🔬 Renal & Urinary Diagnostics

Key serum labs

LabNormalMeaning
BUN10–20 mg/dLProtein-waste byproduct; ↑ in kidney failure, dehydration, high-protein diet, GI bleed
Creatinine0.6–1.3 mg/dL"Critical Kidney Lab." Best indicator of kidney function — >1.3 = bad kidney. Made by muscle wear & tear, cleared only by kidneys
BUN:Creatinine ratio10:1–20:1↑ ratio with normal creatinine = dehydration / prerenal; both ↑ = intrinsic kidney damage
GFR>90 mL/minStages CKD. <60 for ≥3 months = CKD; <15 = kidney failure (ESRD)
Potassium3.5–5.0 mEq/LKidneys excrete K⁺. Failure → hyperkalemia (peaked T waves, dysrhythmias)

Urinalysis (UA) — "a UA should be boring"

Normal urine is clear, pale yellow, no sediment. Specific gravity 1.005–1.030 (high = concentrated/dehydrated, low = dilute).

Dipstick findingInterpretation
Positive leukocyte esteraseWBCs present → infection
Positive nitritesBacterial conversion of nitrates → highly accurate for UTI
Cloudy colorInfection (WBCs/pus make urine cloudy)
ProteinGlomerular damage (nephrotic syndrome, diabetes)
Positive heme/bloodBlood, or myoglobin from rhabdomyolysis
Glucose/ketones/bilirubinAbnormal — should be absent

Imaging & procedures

KUB x-ray, renal ultrasound (no contrast — safe in renal impairment), CT (locates/sizes stones), IVP, cystoscopy, renal biopsy (hold pressure, monitor for bleeding/hematuria after).

A cystoscopy is a risk factor for UTI — any instrumentation of the normally sterile urinary tract introduces bacteria.

Contrast caution

Iodinated contrast is nephrotoxic. Check creatinine/GFR first, hydrate, and hold metformin 48 h around contrast (lactic acidosis risk).

🚽 CAUTI Prevention & Catheter Care

Catheter-associated UTI is the most common HAI. Remember the "No CAUTI" bundle:

✅ DO (reduce CAUTI risk)

  • Insert only when truly Needed; remove ASAP
  • Aseptic insertion technique
  • Keep drainage bag below bladder (no backflow)
  • Keep tubing unobstructed/unkinked
  • Perineal care every shift & PRN
  • Secure catheter; maintain closed system

🚫 NEVER

  • No prophylactic antibiotics for catheters
  • No routine catheter irrigation (breaks closed system)
  • Don't let the bag touch the floor or rise above bladder
  • Don't leave it in "just in case"
"Monitoring for fever" detects a UTI — it does not prevent one. Prevention questions want bundle interventions, not surveillance.

🦠 Urinary Tract Infection — Cystitis vs Pyelonephritis

Cystitis (lower UTI)Pyelonephritis (upper UTI/kidney)
LocationBladderKidney (usually one side)
SignsDysuria, frequency, urgency, suprapubic pain, cloudy/foul urineAbove + flank/CVA tenderness, high fever, chills, N/V
SeverityUsually treated outpatient PO antibioticsMore serious — can lead to sepsis; may need IV antibiotics

Risk factors (esp. cystitis)

Female (short urethra) Catheter / instrumentation Wiping back-to-front Diabetes (glucosuria feeds bacteria) Urinary retention/stasis Sexual activity

Client teaching to prevent UTI

Adequate fluids, void after intercourse, wipe front-to-back, avoid bladder irritants (caffeine, alcohol, citrus, spicy), cotton underwear, complete the full antibiotic course.
Frequent urination with dysuria points to a UTI, not incontinence. Incontinence is usually painless.

💧 Urinary Incontinence — 4 Types

TypeKey cueMechanism / management
StressLeaks with cough/sneeze/laugh/liftingWeak pelvic floor (childbirth, aging) → Kegels, pessary, weight loss
Urge"Gotta go NOW" → sudden strong desire then lossOveractive/irritable detrusor → bladder training, anticholinergics (oxybutynin), avoid irritants
OverflowDribbling, incomplete emptying, nocturiaObstruction/retention (BPH) or weak detrusor → treat obstruction, intermittent cath
FunctionalGU tract is fine — can't reach toilet in timeMobility/cognition barrier → scheduled toileting, assistive devices, accessible bathroom

Psychosocial integrity

Promote autonomy & dignity: involve client in scheduling toileting, use respectful non-judgmental communication, offer assistive devices. Never recommend social isolation or "minimizing discussion."

🧪 Nephrotic Syndrome & Glomerulonephritis

Nephrotic Syndrome

Glomerular membrane becomes leaky to protein. The classic tetrad:

  • Massive proteinuria (>3.5 g/day)
  • Hypoalbuminemia
  • Edema (periorbital, generalized)
  • Hyperlipidemia

Mgmt: ACE inhibitors/ARBs (↓ proteinuria), corticosteroids, diuretics, low-sodium, monitor for infection & clots.

Glomerulonephritis

Inflammation of glomeruli, often post-streptococcal (1–2 wks after strep throat/skin infection).

  • Hematuria (tea/cola-colored urine)
  • Proteinuria, oliguria
  • Edema, hypertension
  • ↑ BUN/creatinine, ↑ ASO titer

Mgmt: antibiotics for residual infection, BP control, fluid/sodium restriction, monitor I&O and daily weights.

Nephrotic = Protein loss (think "leaky"). Nephritic (glomerulonephritis) = blood + hypertension + mild protein.

🎗️ Bladder Cancer & Urinary Diversion

Most common sign: painless gross hematuria. Biggest risk factor: cigarette smoking (also industrial dyes/chemicals). Diagnosed by cystoscopy + biopsy.

Urinary diversions (after cystectomy)

Stoma teaching

Healthy stoma = pink/red & moist. Report dusky/dark/blue (ischemia). Expect mucus in urine (normal — from bowel segment). Empty pouch when ⅓ full; protect peristomal skin; ensure continuous urine flow.

⚡ Acute Kidney Injury (AKI) vs Chronic Kidney Disease (CKD)

AKICKD
OnsetSudden (hours–days), often reversibleGradual, irreversible (GFR <60 for ≥3 months)
Triggers/causesPrerenal (hypotension, dehydration, hemorrhage, shock), intrarenal (ATN, nephrotoxins, contrast), postrenal (obstruction)#1 Diabetes, #2 Hypertension; also PKD, repeated AKIs, glomerulonephritis
AnemiaUsually not yetYes — low erythropoietin
Reversible?Often, if perfusion restored quicklyNo — manage & slow progression

Shared complications of failing kidneys

Fluid volume overload Hyperkalemia Metabolic acidosis ↑ BUN/creatinine (uremia) Anemia (CKD) Hyperphosphatemia / ↓ Ca²⁺

Phases of AKI

Onset
initial insult
Oliguric
<400 mL/day, ↑K⁺, fluid overload
Diuretic
↑ output, risk dehydration/↓K⁺
Recovery
gradual return
Kidneys are "fragile flowers" — repeated hypotension/dehydration that isn't corrected turns reversible AKI into permanent CKD.

🩺 CKD — Priorities, Anemia & Teaching

Priority with fluid overload (edema + crackles + HTN + SOB)

This is an ABC/breathing problem → administer prescribed loop diuretic first. Do NOT increase fluids, give K⁺, or lay supine.

Erythropoietin (epoetin alfa) therapy

Kidneys make erythropoietin → stimulates RBC production. CKD clients lack it → anemia. We replace the hormone, not iron/B12/folate.

Erythropoietin thickens the blood. Complications = hypertension, clotting (DVT/PE/stroke). A BP of 160/95 after EPO = report it. Goal Hgb ~10–11 (keep them off transfusions), not normal range.

Renoprotection

ACE inhibitors/ARBs protect glomeruli (dilate efferent arterioles, ↓ proteinuria) beyond just BP control — that's why so many diabetics/CKD clients take them. Also: BP & glucose control, avoid nephrotoxins (NSAIDs, contrast), phosphate binders, manage acidosis & anemia.

Fluid-overload discharge teaching

Weigh daily (sudden gain = fluid), follow fluid & sodium restriction, report ankle swelling or difficulty breathing. Wrong statement = "I can drink all I want as long as I avoid salt."

🩸 Renal Replacement Therapy

Hemodialysis (HD)

Blood filtered through a machine 3×/week. Needs vascular access.

  • Hold BP meds & certain drugs before HD (dialyzable)
  • Weigh before/after; assess for hypotension, cramping
  • Disequilibrium syndrome: HA, N/V, confusion (rapid solute shifts)

Peritoneal Dialysis (PD)

Dialysate instilled into peritoneal cavity via catheter; gentler on the heart.

  • Warm dialysate; track inflow/outflow balance
  • Outflow should be clear/straw-colored
  • Better option for clients with heart failure

AV Fistula / Graft (HD access)

EMERGENCY — no thrill & no bruit

The access is clotted. Notify the provider/nephrologist immediately. Do not use the site, don't "reassess in 30 min," don't apply warm compress and proceed.
Clients with heart failure may be turned down for an AV fistula — the high-flow shunt overworks an already weak heart. They're steered toward peritoneal dialysis.

Peritonitis (PD's feared complication)

Signs: cloudy dialysate outflow (WBCs), abdominal pain/tenderness, ↑ WBC, fever, N/V, rigid/board-like abdomen, guarding, rebound tenderness. Can become sepsis → death. Straw-colored outflow & bradycardia are NOT signs (expect tachycardia).

🫧 Polycystic Kidney Disease (PKD)

Autosomal dominant. Fluid-filled cysts replace kidney tissue → progressive enlargement & chronic renal failure.

Flank pain Hematuria (cysts bleed) Hypertension → headaches Palpable abdominal mass / huge belly Recurrent UTIs / pyelonephritis Progresses to dialysis
PKD classic answer = flank pain + hematuria. Jaundice/clay stools = biliary; petechiae/bleeding gums = platelet issue; bradycardia/dry skin = hypothyroid. Don't get baited.

🪨 Renal Calculi (Kidney Stones)

Renal calculi = the stone(s). Renal colic = the excruciating pain when a stone moves into the ureter.

Classic presentation (renal colic)

Sudden, severe, sharp flank pain radiating to the groin/testicle, N/V, diaphoresis, pallor, hematuria. Clients appear restless & desperate.

Pain patternThink…
Flank → groin, hematuriaRenal colic
Epigastric → backPancreatitis
RUQ after fatty mealCholecystitis/biliary colic
Central abdominal, distension, vomitingBowel obstruction

Management

Do not "encourage fluids to flush it out" during acute colic before imaging — fluid behind an obstructing stone causes hydronephrosis & more pain. Hydration is for prevention, not the acute attack.

🔁 Renal Transplantation

Signs of rejection

Fever, ↓ urine output, weight gain/edema, pain/tenderness over the graft, ↑ BP, rising creatinine. Report immediately.

Teaching

Take immunosuppressants exactly as prescribed (never skip), avoid sick contacts & crowds, monitor for infection, daily weights & BP, no live vaccines.

🫀 Hepatobiliary (Module 10)

LFTs · Cirrhosis · Portal HTN · Ascites · Varices · Encephalopathy · Hepatitis · Liver Cancer · Gallbladder · Pancreatitis

🧫 Liver Functions → Why Disease Hurts

The liver does a huge amount; when it fails, each lost function creates a classic problem:

Liver functionWhen it fails…
Conjugates/excretes bilirubinJaundice, dark urine, clay/pale stools, pruritus
Makes clotting factorsBleeding, ↑ PT/INR, bruising
Makes albumin↓ oncotic pressure → edema & ascites
Converts ammonia → urea↑ ammonia → hepatic encephalopathy
Metabolizes drugs/toxinsDrug toxicity, altered dosing
Stores glycogen, vitaminsHypoglycemia, nutritional deficiencies
Filtered by portal circulationBlockage → portal hypertension

🧪 Hepatic Diagnostics — LFTs & Key Numbers

TestNormal-ishMeaning
AST / ALTAST 10–40, ALT 7–56 U/LHepatocellular injury. ALT more liver-specific. ↑↑ in hepatitis
ALP~40–120 U/L↑ in biliary obstruction/cholestasis
Bilirubin (total)0.3–1.2 mg/dL↑ → jaundice (visible >~2–3)
Albumin3.5–5 g/dL↓ in chronic liver disease → edema/ascites
Ammonia15–45 mcg/dL↑ → encephalopathy
PT / INRINR ~1.0↑ = impaired synthesis of clotting factors → bleeding risk

Other: abdominal ultrasound, CT/MRI, FibroScan, liver biopsy (check coags first; position on right side with pressure afterward to prevent bleeding).

Hepatocellular damage = ↑ AST/ALT. Obstruction/biliary = ↑ ALP & bilirubin. Synthetic failure = ↓ albumin, ↑ INR.

🪨 Hepatic Cirrhosis — The Hub Disease

Chronic, irreversible scarring (fibrosis) replaces functional liver tissue. Causes: chronic alcohol use, viral hepatitis (B/C), NAFLD, biliary obstruction.

Manifestations

Jaundice Ascites Spider angiomas Palmar erythema Caput medusae Bruising / bleeding Asterixis Gynecomastia Fetor hepaticus

The cirrhosis cascade

Scarring → blood can't flow through liver → portal hypertension → ascites + esophageal varices + splenomegaly; loss of function → ↓ albumin, ↑ ammonia, ↑ INR → encephalopathy & bleeding.

🩸 Portal Hypertension · Ascites · Varices

Portal Hypertension

↑ pressure in portal vein from liver scarring. Drives ascites, varices, splenomegaly, caput medusae.

Ascites

Fluid in peritoneal cavity (↓ albumin + portal HTN + Na⁺/H₂O retention). Mgmt: low sodium, diuretics (spironolactone), fluid restriction, paracentesis, daily weight & abd girth.

Esophageal Varices

Distended fragile veins that can rupture → massive hemorrhage (life-threatening emergency).

Bleeding varices = emergency

Maintain airway, suction, large-bore IV/fluids/blood, octreotide/vasopressin, endoscopic banding/sclerotherapy, balloon tamponade (Sengstaken-Blakemore). Avoid coughing/straining/NSAIDs.

Paracentesis nursing

Have client void first (avoid bladder puncture), position upright/Fowler's, monitor for hypotension after large-volume removal, measure/label fluid, daily weight & girth.

🧠 Hepatic Encephalopathy & Failure

Failing liver can't convert ammonia → urea; ammonia crosses the blood-brain barrier → neuro decline.

Signs (early → late)

Confusion, mood change
Asterixis (flapping tremor)
Lethargy, fetor hepaticus
Stupor → coma

Lower the ammonia

Lactulose — traps & excretes ammonia in stool; titrate to 2–3 soft stools/day (not diarrhea). Rifaximin — gut antibiotic kills ammonia-producing bacteria. Monitor mental status & ammonia.
Protein used to be heavily restricted — current practice favors adequate protein with lactulose; only modest restriction if severe. Don't pick "eliminate all protein."

🥗 Nutritional Deficiencies in Hepatic Disorders

🦠 Viral Hepatitis

TypeRouteKey points
AFecal-oral (food/water)Acute, self-limiting; vaccine available; hand hygiene
BBlood/body fluids, perinatal, sexualCan be chronic → cirrhosis/cancer; vaccine available
CBlood (IV drug use, transfusions)Often chronic; leading cause of transplant; no vaccine; curable with antivirals
DCo-infects with BOnly with HBV present
EFecal-oral (water)Like A; dangerous in pregnancy

Phases: preicteric (flu-like, anorexia, RUQ pain) → icteric (jaundice, dark urine, clay stools, pruritus) → convalescent. Teaching: rest, avoid alcohol/hepatotoxins (acetaminophen), standard precautions, no sharing razors/needles.

"A E come from the Alimentary tract (fecal-oral, vowels). B, C, D are Blood-borne." Vaccines exist for A & B only.

🎗️ Liver Cancer

Often secondary to cirrhosis or chronic hepatitis B/C. Signs: weight loss, RUQ pain/mass, worsening jaundice/ascites, ↑ alpha-fetoprotein (AFP). Mgmt: resection, ablation, chemoembolization (TACE), transplant. Mostly palliative when advanced.

🫛 Gallbladder — Cholelithiasis & Cholecystitis

Cholelithiasis = gallstones. Cholecystitis = inflammation, usually from a stone obstructing the cystic duct.

Risk factors — the "4 F's"

Female Forty (40+) Fat (obesity) Fertile (multiparity/estrogen)

Manifestations

RUQ pain after a fatty meal, may radiate to right shoulder; N/V; +Murphy's sign (arrest of inspiration on RUQ palpation); fever; if obstruction → jaundice, clay stools, dark urine.

Cholecystectomy (usually laparoscopic)

ERCP

Endoscopic Retrograde Cholangiopancreatography — scope visualizes & clears bile/pancreatic ducts (remove stones, stent). NPO before; after: monitor for post-ERCP pancreatitis (severe pain, ↑ amylase/lipase), perforation, bleeding; check gag reflex before resuming PO.

🔥 Pancreatitis

Autodigestion of the pancreas by its own enzymes. Top causes: gallstones & chronic alcohol use.

Manifestations

Management — "rest the pancreas"

NPO (↓ enzyme stimulation), NG suction if vomiting/ileus, IV fluids, pain control (opioids), electrolyte correction (esp. calcium), monitor glucose. Chronic: pancreatic enzyme replacement with meals, low-fat diet, no alcohol.
Don't confuse the pain patterns: pancreatitis = epigastric → back; cholecystitis = RUQ after fatty meal → right shoulder; renal colic = flank → groin.

⚡ Quick-Fire Review — Hepatobiliary

💧 Diuretics

DrugUseWatch for
Furosemide (loop) HYFluid overload in CKD/AKI/ascites; pulmonary edema↓ K⁺, ↓ Na⁺, dehydration, ototoxicity, ↑ glucose. Monitor I&O, daily weight
Hydrochlorothiazide (thiazide)HTN, mild edema↓ K⁺, ↓ Na⁺, ↑ glucose, ↑ uric acid. Weak if GFR low
Spironolactone (K⁺-sparing) HYAscites (cirrhosis), heart failure↑ K⁺ (hyperkalemia), gynecomastia
Loop diuretics waste potassium; spironolactone spares it. Don't combine spironolactone with K⁺ supplements or ACE/ARB carelessly → dangerous hyperkalemia.

🫀 ACE Inhibitors & ARBs

-pril (lisinopril) = ACE. -sartan (losartan) = ARB.

First-line for renoprotection in diabetes/CKD & to ↓ proteinuria in nephrotic syndrome — they protect the glomeruli beyond just lowering BP.
ACE cough = the "-pril tickle." Switch to a "-sartan" (ARB) if cough is intolerable.

🩸 Erythropoietin (Epoetin alfa) HY

Why

CKD kidneys stop making EPO → anemia. Replace the hormone (not iron/B12/folate).

Goal

Hgb ~10–11 to avoid transfusions — not normal range.

EPO thickens blood → hypertension, DVT/PE/stroke. A rising BP after EPO is the complication to report. Don't pick "needs iron therapy" for CKD anemia.

🦴 Phosphate Binders & CKD Mineral Meds

DrugUseKey point
Calcium acetate / sevelamerBind dietary phosphate in CKDGive WITH meals HY — that's the whole point (binds food phosphate)
Calcitriol (active vit D)↓ Ca²⁺ in CKDMonitor calcium
Sodium polystyrene (Kayexalate)HyperkalemiaPulls K⁺ into gut → excreted in stool; expect diarrhea
Phosphate binders with food = treatment. Taken between meals = useless. Stool softeners/laxatives are taken differently — read the timing in the question.

🚽 Urinary / Incontinence Meds

DrugUseWatch
Oxybutynin (anticholinergic)Urge incontinence/overactive bladderAnticholinergic effects: dry mouth, constipation, urinary retention, confusion (elderly)
PhenazopyridineUTI dysuria (analgesic)Turns urine orange/red — harmless; warn client
Tamsulosin (alpha-blocker)BPH/overflow, helps stone passageOrthostatic hypotension
Phenazopyridine staining urine orange is expected — it's a classic "is this normal?" teaching point. (Also stains contacts/clothes.)

🧠 Liver / Hepatic Encephalopathy Meds HY

DrugUseKey point
Lactulose↓ ammonia in encephalopathyTitrate to 2–3 soft stools/day. Too much = dehydration; too little = no effect
RifaximinGut antibiotic; kills ammonia-making bacteriaAdd-on to lactulose
Vitamin KBleeding from ↑ INRLiver can't make clotting factors
Propranolol (beta-blocker)Prevent variceal bleeding (↓ portal pressure)Monitor HR/BP
OctreotideAcute variceal bleedSplanchnic vasoconstriction ↓ bleeding
Lactulose causing 2–3 soft stools/day = therapeutic, not an adverse effect. If the client has no stools, the ammonia stays high — hold-the-dose logic is wrong here.

🍽️ Pancreatic / Biliary & Supportive

DrugUseKey point
Pancrelipase (enzymes)Chronic pancreatitis / malabsorptionWith every meal/snack; don't crush enteric-coated; wipe lips (skin irritation)
Opioids (e.g., morphine/hydromorphone)Severe pancreatitis/renal colic painPain control is a priority; monitor sedation/resp
Ketorolac (IV NSAID)Renal colic painAvoid in renal impairment/long-term
OndansetronN/V (colic, pancreatitis, hepatitis)Monitor QT
AntibioticsPyelonephritis, peritonitis, infected stonesFinish full course; culture before starting if able

Hepatotoxic / nephrotoxic — know these

Acetaminophen (liver — limit/avoid in hepatic disease), NSAIDs & contrast dye & aminoglycosides (kidney). Hold metformin around IV contrast.

🗺️ Mind Maps

See the big picture — how it all connects

🫘 AKI vs CKD — at a glance

ACUTE KIDNEY INJURY CHRONIC KIDNEY DISEASE Onset: SUDDEN (hrs–days) Causes: pre-renal (↓BP, dehydration), intra-renal (ATN, nephrotoxins), post-renal Often REVERSIBLE if perfusion restored Phases: onset→oliguric→diuretic→recovery Anemia: usually NO (yet) Onset: GRADUAL (GFR<60 ≥3 mo) Causes: #1 Diabetes, #2 Hypertension PKD, repeated AKIs, glomerulonephritis IRREVERSIBLE — slow progression 5 stages by GFR; stage 5 = ESRD/dialysis Anemia: YES (low EPO) Both → fluid overload, ↑K⁺, metabolic acidosis, ↑BUN/Cr Repeated AKI can → become CKD

🩸 Failing Kidney — the ripple effects

FAILING KIDNEY ↓EPO → anemia Fluid overload ↑K⁺ (cardiac) Metabolic acidosis ↑Phosphate / ↓Ca Poor wound healing

Cause of death in CKD = heart disease (heart pumps in a toxic, overloaded environment).

🫀 The Cirrhosis Cascade HY

CIRRHOSIS (scarring) ① PORTAL HYPERTENSION ② LOST FUNCTION Ascites Esophageal varices Splenomegaly ↓Albumin→edema ↑INR→bleeding ↑Ammonia→encephalopathy ↑Bilirubin→jaundice Varices rupture = airway + hemorrhage EMERGENCY · Lactulose for encephalopathy

Three "pain triangles" — match the radiation pattern to the organ: RUQ→shoulder (gallbladder), flank→groin (kidney stone), epigastric→back (pancreas).

📝 Lecture Summary

Module 9 exam-prep session with the course faculty (1h 24m)

🎙️ M09 — Disorders of the Renal & Urinary Systems

The lecture walks through 15 practice questions with rationales and test-taking tips. Tap each to expand. Full Q&A versions are also in the Quiz → Lecture filter.

Know your UA dipstick 4 incontinence types EPO = thick blood Thrill + bruit or STAT Cloudy PD = peritonitis

🧠 Test-Taking Tips From the Docs

Cross it off

On your whiteboard write 1-2-3-4 and X out wrong options so you don't hold them in your head.

SATA = only what you're sure of

One right answer is possible. A wrong check cancels a right one — don't guess.

"Needs more teaching" = find the FALSE statement

Write "FALSE" at the top; mark each option T/F.

Psychosocial = autonomy + dignity

Picture yourself as the patient. Never isolate or ignore.

Know the mechanism

If you know what a drug/organ does, the complication answers itself (e.g., EPO → thick blood).

ABCs win priority questions

Crackles + SOB → breathing problem → diuretic before teaching.

📋 The 15 Questions — High-Yield Points

Q1 · UA dipstick interpretation

+Leukocyte esterase = WBCs present. +Nitrites = bacterial conversion → accurate for UTI. Specific gravity 1.035 = concentrated. Cloudy = infection (WBCs). Normal urine is clear & colorless.

Q2 · Functional incontinence (psychosocial SATA)

Support autonomy & dignity: involve client in toileting schedule, respectful communication, offer assistive devices. Never recommend isolation or "minimize discussion."

Q3 · Erythropoietin complication HY

EPO thickens blood → hypertension (160/95) is the complication to report. Rising Hgb is expected. Goal ~10–11, not normal.

Q4 · Urge incontinence (SATA)

Sudden strong desire then involuntary loss = urge. Leak with cough = stress. Frequency + dysuria = UTI. Nocturia/incomplete emptying = overflow. Only the urge definition is correct.

Q5 · CKD priority — fluid overload

Edema + crackles + SOB + HTN = overload → give loop diuretic. Don't ↑ fluids, give K⁺, or lay supine.

Q6 · Polycystic kidney disease

Big blood-filled cysts → flank pain + hematuria. Distractors: jaundice/clay stools (biliary), petechiae/bleeding gums (platelets), bradycardia/dry skin (thyroid).

Q7 · Esmolol IV math (dimensional analysis)

45 mcg/kg/min, 59 kg, 2500 mg/250 mL → set pump to 15.9 mL/hr. Convert mcg→mg→mL, cancel units, round to tenth.

Q8 · Fluid-overload teaching (find the wrong statement)

Wrong = "I can drink as much as I want if I avoid salt." Right behaviors: daily weight, follow fluid restriction, report swelling/SOB.

Q9 · AV graft — no thrill/bruit HY

Access is clotted → notify provider immediately. Don't reassess later, warm compress, or use the site.

Q10 · Cystitis risk factors (SATA)

Risks: cystoscopy, short female urethra, wiping back-to-front, diabetes. Not risks: adequate fluids, voiding after sex (both protective).

Q11 · Matrix — AKI vs CKD vs Pyelonephritis

AKI = sudden, trauma/dehydration/hypotension. CKD = DM/HTN, anemia, poor healing. Pyelonephritis = infection, antibiotics, can → sepsis. Overload/↑K⁺/acidosis/dialysis = AKI & CKD.

Q12 · CAUTI prevention (SATA)

Bag below bladder, remove ASAP, no kinks, peri-care each shift. No prophylactic antibiotics, no routine irrigation. Monitoring for fever detects, doesn't prevent.

Q13 · Renal failure priority (ABC twin of Q5)

Crackles = fluid in lungs = breathing problem → diuretic first, before teaching or monitoring.

Q14 · Renal colic recognition

Severe sharp flank → groin pain + hematuria. Distractors: epigastric→back (pancreatitis), RUQ after burger (gallbladder), central + distension (obstruction).

Q15 · Peritonitis on PD (SATA) HY

Signs: cloudy outflow, abdominal pain, ↑WBC, fever, N/V. Straw-colored outflow = normal. Expect tachycardia (not brady). Watch for rigid/board-like abdomen, guarding, rebound.

🫀 Module 10 — Hepatobiliary Lecture

Wagner Weeks 10 L1 & L2 in the same format. Full slide-by-slide is in the Wagner Lectures tab; the high-yield beats:

Liver = bleeding, bleeding, bleeding Confusion + liver = ammonia → lactulose Assess jaundice at the sclera Varices bleed → stabilize BP first Tylenol OD → acetylcysteine Murphy's sign = cholecystitis Pancreatitis = NPO
L1 · Liver jobs & labs HY

Liver metabolizes glucose/stores glycogen, converts ammonia→urea, handles proteins/fats/vitamins, makes bile clotting factors (bleeding breaks first). Labs: ALT most liver-specific, AST less so, ALP = biliary obstruction, ↑ammonia → encephalopathy, ↑bilirubin → jaundice, ↓albumin → ascites, ↑INR/PT → bleeding. Biopsy: check INR first (give vitamin K if high), lie on the right side after.

L1 · Cirrhosis → portal HTN → ascites & varices HY

Scar tissue replaces working liver (most commonly from alcohol). Assess jaundice at the sclera. Scarring → portal hypertension → ascites & varices. Ascites: biggest danger is respiratory compromise; treat with spironolactone, sodium restriction, paracentesis (give albumin after), or TIPS. Varices: rupture = massive bleed (first-bleed mortality 10–30%). Bleeding varices → stabilize BP first (fluids, blood, vasopressors), protect airway, then band/ligate via EGD; reverse anticoagulation with vitamin K.

L1 · Hepatic encephalopathy & the 5 hepatitises

Encephalopathy: ammonia builds → confusion, asterixis (hand flap), fetor hepaticus → treat with lactulose (2–3 soft stools/day; add rifaximin). Hepatitis A & E = fecal-oral, self-limiting (A has a vaccine). B = blood/body fluids/sex/perinatal, vaccine exists, can go chronic. C = blood (IV drug use), no vaccine but antivirals cure ~90%. D = only with B.

L1 · Hepatic failure — Tylenol case HY

Acute failure is often acetaminophen overdose (ceiling ~3–4 g/day; antidote = acetylcysteine, timing-dependent). Case logic: low BP → bleeding or low albumin; confusion → ↑ammonia → lactulose; high INR → bleed risk → vitamin K; give fluids cautiously (ascites risk); monitor LFTs/INR; consult GI for transplant.

L2 · Gallstones & cholecystitis HY

Gallstones (cholelithiasis) are often silent until one blocks a duct → cholecystitis. Risk = the F's (female, fat, forty, fertile, estrogen, rapid weight loss/post-bariatric, T2DM). Signs: biliary colic (RUQ → right shoulder, worse after fatty food), positive Murphy's sign, clay-colored stool, then fever/↑WBC/↑bilirubin/jaundice. Dx: ultrasound → HIDA → ERCP (can remove stones but risks pancreatitis). Surgery: laparoscopic cholecystectomy (home in 24 h; expect CO₂ shoulder pain); open approach may have a T-tube. Post-op = low-fat diet.

L2 · Pancreatitis HY

Auto-digestion by amylase & lipase (top causes gallstones + alcohol, ~80%). Pain: severe, boring, mid-abdomen → back, better leaning forward/fetal, worse lying flat. Labs/signs: ↑amylase lipase, hyperglycemia, hypocalcemia (Chvostek/Trousseau), Cullen's (umbilicus) Grey Turner's (flank) bruising = hemorrhagic. NPO is the top priority (even ice chips stimulate the pancreas): rest it with IV fluids/TPN, NG tube, pain control, antiemetics, H2/PPI, pancrelipase; no alcohol/smoking.

🫘 Week 9 · Lecture 1 — Incontinence, UTI, Bladder Cancer, Kidney Basics

The 6 types of incontinence HY

Stress

Weak pelvic floor (often after childbirth). Leaks with cough/sneeze/laugh. Fix: Kegels.

Urge

Sudden strong urge → leak. Bladder wall irritation (classic w/ UTI). Fix: meds, treat cause.

Overflow

Bladder never empties — often men w/ BPH. Dribbling, straining. Fix: treat BPH, intermittent cath.

Reflex / Neurogenic

Brain–bladder connection lost (spinal cord injury, MS, stroke). Spastic (empties on reflex, common) or flaccid. Fix: bladder training, self-cath.

Functional

Bladder works, but a barrier stops them — dementia, mobility, environment. Connection intact = cognitive issue.

Transient

Temporary & reversible — UTI, med, injury. Fix the cause, it resolves.

Incontinence is never a normal part of aging. Always treat it.
The 4 P's every hour to prevent falls: Pain · Potty · Position · Possessions.
UTI ladder + urosepsis HY
Urethritis
(often STI)
Cystitis
(bladder)
Ureteritis
Pyelonephritis
(kidney)
Urosepsis

Most UTIs = E. coli from stool. Bladder infection usually no fever; once it hits the kidney → fever, high WBC, flank pain = pyelonephritis.

Urosepsis is the #1 cause of sepsis. Treat suspected UTI with antibiotics right away — don't wait for the culture (culture takes ~48h, then narrow the drug).

Cotton is king — breathable underwear lowers UTI risk. Avoid synthetics, hot tubs, wet clothes. Wipe front-to-back. Cranberry (unsweetened) may help bacteria not stick.

CAUTI prevention HY

✅ DO

  • Sterile insertion (2-nurse check is common)
  • Ask daily: does this catheter still need to be in?
  • Bag below bladder, no kinks, closed system
  • Peri-care every shift (clean the whole area + tube)
  • Empty bag before it's half full

🚫 NEVER

  • Place a catheter for your convenience
  • Leave it >48h without reassessing
  • Prophylactic antibiotics / routine irrigation
  • Let the bag touch the floor or rise above bladder
CMS/Joint Commission call CAUTIs "never events." Get the catheter OUT ASAP.
Bladder cancer & urinary diversion

#1 sign = gross, painless hematuria (actual blood, not tinge). Risks: smoking, male, older age, occupational dyes. Dx: cystoscopy + biopsy, CT.

Unique treatment: chemo goes into the bladder (intravesical), not IV — IV chemo gets filtered out before it reaches the bladder. Also BCG immunotherapy (held ~2h), radiation, surgery.

After cystectomy → diversion: urostomy tubes or ileal conduit (ureters → piece of ileum → stoma). Watch stoma color: should look like inside of your cheek (pink/moist). Dark red/blue/black/brown = poor perfusion = bad. Protect skin with wafer/barrier; change pouch q3–7 days.

Kidney functions, blood flow & the 3 labs HY

When kidneys fail, you lose: waste removal (ammonia builds → confusion), fluid/electrolyte control (K⁺, Na⁺, Mg²⁺ ↑), vitamin D activation (weak bones), BP control (fluid overload → HTN), erythropoietin (→ anemia → tired), acid-base buffering (→ metabolic acidosis).

Blood flow: artery → glomerulus (capillary bed) → Bowman's capsule → convoluted tubules → Loop of Henle (potassium!) → collecting tubule → renal pelvis → ureter → bladder. Adrenal glands sit on top but aren't part of the kidney.

BUN

Amino-acid waste. ↑ with kidney injury, dehydration, bleeding, hypotension. Less specific.

Creatinine

Muscle-metabolism waste. Most accurate marker of kidney function.

GFR

Calculated filtering number. Want >90. Defines CKD stage.

Renal biopsy: patient prone, ultrasound-guided needle. Watch for bleeding (very vascular) + infection; pressure dressing after.

🫘 Week 9 · Lecture 2 — Glomerulonephritis, Nephrotic, AKI, CKD, Dialysis

Glomerulonephritis → Nephrotic syndrome

Glomerulonephritis = inflammation of the glomeruli (primary, or secondary from a systemic infection). Sign: reddish-brown / "Coca-Cola" urine, edema, HTN, N/V. Treat symptoms first, then antibiotics for the cause; sometimes hemodialysis to rest the kidney.

Nephrotic syndrome = the result of badly scarred glomeruli. Classic 4: severe pitting edema, low albumin, foamy (protein) urine, high cholesterol. Treat the symptom (albumin, dialysis) + the cause.

AKI — 4 phases + pre/intra/post-renal HY
1. Onset
hrs–days
2. Oliguric
100–400 mL/day, K⁺↑
3. Diuretic
2–4 L/day, watch dehydration
4. Recovery
up to 1 year

Pre-renal

Before the kidney — not enough blood. Dehydration, blood loss, cardiac failure, sepsis, hypotension.

Intra-renal

Inside the kidney — direct damage. Pyelo, glomerulonephritis, nephrotic; nephrotoxic drugs (aminoglycosides, cephalosporins, contrast dye, NSAIDs).

Post-renal

After the kidney — obstruction. Kidney stones, BPH, cancer, urethral stricture (urine backs up).

Hyperkalemia in AKI → peaked T waves on EKG. Telemetry, telemetry, telemetry.
CKD — staged by GFR HY

Don't memorize all 5 stages. Memorize the 2 numbers:

GFR > 90

Excellent kidney function.

GFR < 15

Patient needs dialysis.

Slow it down: control BP (biggest lever), drink water (~2 L unless overloaded), stop smoking, limit alcohol, avoid NSAIDs, finish antibiotics.

Replace what the kidney can't do: calcitriol (activate vit D) + calcium carbonate (bones), epoetin + iron (anemia), loop diuretic / Kayexalate (potassium), phosphate control. Diet: low protein if not dialyzed (protein OK once dialyzed), limit abnormal electrolytes, high complex carb, moderate fat.

Uremic frost: urea pushed out through pores → salty, itchy, dry skin → patients scratch & get cuts. Keep skin clean + moisturized.
"Abnormal" can be normal for that patient — a CKD patient always has high BUN/creatinine. Watch for change, not just the number.
Dialysis — Peritoneal vs Hemo HY

Neither replaces the kidney's hormonal jobs (vit D, EPO) — only fluids, electrolytes, acid-base, waste.

Peritoneal (PD)

Dialysate (hypertonic, high glucose) instilled into abdomen → dwell time → drain. Done at home, gentler, fewer diet limits, good for heart-failure/older patients. Big risk = peritonitis.

Hemodialysis (HD)

Blood pumped through a dialyzer, ~3×/week, 3–4h. Uses heparin. Watch hypotension (pulls ~250 mL out at start) disequilibrium syndrome (rapid shift → cerebral edema → HA/nausea early, seizures late → slow the rate).

PERITONITIS = fever + abdominal pain + CLOUDY outflow. Straw-colored outflow is normal. Assess, then call provider → antibiotics (finish the course).
Protect the AV fistula/graft arm. No BP, no IV, no blood draws in that arm (a BP cuff can blow the fistula). Before every access: feel the thrill, hear the bruit — no thrill/bruit = clotted = call provider.

Access types: temp central venous catheter (emergent, into right atrium) → AV fistula (vein+artery, needs weeks to mature) → AV graft (synthetic tube). Hold meds before HD (beta blockers etc. get filtered out) unless told otherwise.

Kidney transplant

Restores hormonal function — EPO, BUN/creatinine, GFR, acid-base all normalize. Donor: living, non-heart-beating, or cadaver; related donor best.

Lifelong immunosuppressants are an absolute must — miss them and the kidney rejects. Even more important than "finish your antibiotics."

🫀 Week 10 · Lecture 1 — Liver, Cirrhosis, Portal HTN, Hepatitis

What the liver does + liver labs HY

Liver jobs: metabolize glucose/store glycogen, convert ammonia→urea, handle proteins/fats/vitamins, make bile & bilirubin, metabolize drugs, and make clotting factors (bleeding is often the first thing to break).

ALT

Most specific to the liver. Tracks if treatment is working.

AST

Rises with liver damage, less specific.

ALP

Marker of biliary obstruction.

Ammonia

↑ when liver can't make urea → hepatic encephalopathy.

Bilirubin

↑ → jaundice.

Albumin / INR

Low albumin → ascites. High INR/PT → bleeding.

Liver biopsy: check INR first (give vitamin K if high); afterward lie on right side to tamponade; watch for bleeding.

Cirrhosis + jaundice HY

Cirrhosis = scar tissue replaces working liver. Most common cause = alcohol; also hepatitis, fatty liver (metabolic syndrome/steatohepatitis), biliary obstruction. Compensated (looks well, vague symptoms) vs decompensated (jaundice, portal HTN, hepatorenal syndrome).

Jaundice: best assessed at the sclera (works on all skin tones). Skin can range from mild to "yellow highlighter."
Portal hypertension → ascites, varices HY
Scarred liver
Portal hypertension
Ascites & varices

Ascites: pressure + low albumin push fluid into the abdomen. Biggest danger = respiratory compromise (fluid pushes on lungs). Treat: spironolactone (blocks aldosterone), sodium restriction (not fluid restriction), paracentesis (drain — give albumin after), or TIPS shunt.

Esophageal varices: varicose veins in the esophagus from the backed-up pressure. Rupture = massive bleed, first-bleed mortality 10–30%.

Bleeding varices: stabilize BP FIRST — fluids, blood products, vasopressors — before fixing the source. Protect airway (suction, maybe intubate). Permanent fix = banding/ligation via EGD. Reverse anticoagulation (vitamin K). A Blakemore tube can tamponade (Wagner said NOT on the exam).
Hepatic encephalopathy

Late sign. Ammonia builds up → toxic to brain → confusion, sleep changes, asterixis (hand flap), coma, seizures. Musty "fetor hepaticus" breath.

Treatment = lactulose (binds ammonia, poop it out). Causes diarrhea → watch skin. Builds up over the day — often needs a second dose by night.
The 5 hepatitis types HY
TypeSpreadKey points
AFecal–oral (shellfish, food)Usually mild/self-limiting. Vaccine exists. No chronic cirrhosis.
BBlood & body fluids, sex, mother→babyVaccine exists. Antivirals/interferon. Can → chronic, cirrhosis, cancer.
CIV drug use, blood, needles, tattoos, sexNo vaccine (60+ subtypes). Antivirals cure ~90%. Often silent.
DCo-infection with BPrevent B = prevent D. ↑ risk cirrhosis.
EFecal–oral (poor sanitation, water)Like A — self-limiting, supportive care.

General care: high-carb, high-cal, moderate fat/protein, rest the liver, small frequent meals, no alcohol, vaccinate at-risk, hand hygiene, safe injection, purified water when traveling.

Hepatic failure + Tylenol case study HY

Acute cause = often acetaminophen overdose. Chronic = untreated cirrhosis/hepatitis.

Acetaminophen ceiling ≈ 3–4 g/day. Antidote for Tylenol toxicity = acetylcysteine (timing-dependent).

Case study logic: Low BP → bleeding OR low albumin. Confusion → high ammonia → lactulose. High INR → bleed risk → vitamin K. Give fluids cautiously (ascites risk). Monitor LFTs + INR; consult GI/liver for possible transplant.

🫀 Week 10 · Lecture 2 — Gallbladder & Pancreas

Gallstones & cholecystitis HY

Cholelithiasis = gallstones (often silent). Problem starts when a stone blocks the ductcholecystitis (inflamed gallbladder).

Risk = the 5 F's vibe: female, estrogen/oral contraceptives, obesity/high cholesterol, type 2 diabetes, rapid weight loss (classic after bariatric surgery), older age, Crohn's, Native/Mexican American, multiple pregnancies.

Key signs

Biliary colic = RUQ pain radiating to right shoulder, worse after fatty food. N/V, belching, gas.

Murphy's sign

Push under right ribs, patient inhales — pain = positive = gallbladder.

Clay-colored stool

Bile isn't reaching the gut (fats not broken down) → pale, fatty stool (steatorrhea).

Later

Fever, ↑WBC, ↑bilirubin → jaundice, dark urine.

Gallbladder diagnostics & surgery

Ultrasound (first, best/simplest) → HIDA scan (flow through biliary tree) → ERCP (most invasive: camera to biliary tree, can remove stones — but risks pancreatitis).

Cholecystectomy: usually laparoscopic (home within 24h). Open approach if very inflamed/leaking → longer stay, may have a T-tube (drains bile ~2–4 wks while it heals).

Post-op: low-fat diet (no gallbladder to store bile), expect possible right shoulder pain from CO₂ gas, showers not baths, no lifting >10–15 lb for 4–6 wks.
Pancreatitis HY

Auto-digestion: pancreatic enzymes (amylase & lipase) activate too early and eat the pancreas → inflammation, necrosis, hemorrhage. Top causes = gallstones + alcohol (~80%). Also ERCP, high triglycerides, smoking, trauma, valproic acid.

Pain

Severe, boring, mid-abdomen → back. Better sitting up / fetal / leaning forward; worse lying flat.

Labs/signs

↑ amylase & lipase, hyperglycemia, hypocalcemia (check Chvostek/Trousseau), N/V, absent bowel sounds.

Cullen's sign

Bruising around the belly button = hemorrhagic pancreatitis.

Grey Turner's sign

Bruising on the flank = hemorrhagic pancreatitis.

NPO is a top priority. Even ice chips/water activate the pancreas and cause pain. Rest the pancreas: IV fluids/TPN, NG tube, pain control (fentanyl ± ketorolac), antiemetics, H2 blockers/PPIs, pancrelipase replacement (swallow whole, then a full glass of water), no alcohol/smoking.
⚠️ Bonus preview — NOT on Exam 4

Wagner used the last ~30 min of Wk 10 L2 to start upper GI / enteral nutrition (EGD, NG/G/J/GJ tubes, checking residuals, aspiration precautions). He said clearly this is for a future exam, not Exam 4. Skip if you're short on time.

One handy definition if you want it: Enteral = feeds through the GI tract (tube feeding). Parenteral = TPN + lipids via IV, bypassing the gut.

❓ Q&A Bank — Every Question Asked in the Lectures

Questions Wagner posed to the class, with the answer he was looking for and other options that came up. Tap to reveal.

🫘 Week 9 · Lecture 1

Q1 · A patient has urinary incontinence — what's your nursing management?

Possible answers raised: skin integrity, psychosocial factors, find the underlying cause, check on them more often, toileting schedule.

✅ Key answer

Protect skin integrity, address psychosocial factors, and prevent falls using the 4 P's (Pain, Potty, Position, Possessions) on hourly rounding.
Q2 · Suspected UTI — what's the nurse's first action? (student question)

Options debated: (a) administer prescribed antibiotic, (b) educate on fluid intake since it's only "suspected."

✅ Answer given

Administer the prescribed antibiotic. Suspected UTIs are treated right away (culture takes ~48h, then narrow). Wagner agreed the wording was a bit ambiguous, but the intended answer is antibiotics.
Q3 · How does the body correct metabolic acidosis?

Possible answer raised: "breathing fast."

✅ Answer

Respiratory alkalosis — breathe faster (Kussmaul respirations) to blow off CO₂. So yes, expect an ↑ respiratory rate in kidney-failure patients.

🫘 Week 9 · Lecture 2

Q4 · What do you see on the EKG with hyperkalemia? HY

✅ Answer

Peaked T waves. Seen in AKI when potassium rises → monitor on telemetry.
Q5 · What type of AKI is this — pre-renal, intra-renal, or post-renal? HY

All possible answers:

  • Pre-renal = before the kidney (dehydration, blood loss, cardiac failure, sepsis, hypotension).
  • Intra-renal = inside the kidney (pyelonephritis, nephrotic, glomerulonephritis, nephrotoxic drugs, contrast dye, NSAIDs).
  • Post-renal = after the kidney / obstruction (kidney stones, BPH, cancer, urethral stricture).

💡 Wagner's tip

He said he asks this a lot on tests. Sort by where the problem sits relative to the kidney.

🫀 Week 10 · Lecture 1

Q6 · Case study — why does this patient have a low BP (108/66)?

Possible answers raised: bleeding; low albumin.

✅ Answer

Both are valid concerns. The one Wagner steered to: low albumin → fluid leaks out of the vasculature (also watch for bleeding, given the liver).
Q7 · Case study — what's the diagnosis, and why?

✅ Answer

Liver failure due to acetaminophen (Tylenol) toxicity.
Q8 · Case study — the patient is confused; what's elevated, and how do you treat it?

✅ Answer

Confusion + liver = elevated ammonia (hepatic encephalopathy). Treat with lactulose (binds ammonia, excreted in stool).
Q9 · What's the antidote for acetaminophen overdose? HY

✅ Answer

Acetylcysteine (timing-dependent).
Q10 · A patient is bleeding from esophageal varices / in shock — what do you do?

Possible answers raised: give meds, suction, intubation, transfusion, cauterize, fluids/blood products, vasopressors.

✅ Answer

Stabilize BP first — IV fluids, blood products, and vasopressors (norepinephrine, epinephrine, dopamine). Protect the airway (suction, possible intubation). Then fix the source (EGD banding/cautery). Reverse anticoagulation with vitamin K.

🫀 Week 10 · Lecture 2

Q11 · Is there a way to find gallstones before they cause problems? (student question)

✅ Answer

Ultrasound or CT only — no blood test detects gallstones. They're usually found once they cause symptoms.
Q12 · Why use a J-tube over a G-tube?

Possible answers raised: "if the stomach isn't working" (a good point, Wagner said, but not his target).

✅ Answer

A J-tube (jejunum) puts food past more sphincters, so it's harder to vomit up → lower aspiration risk. But meds work better through a G-tube (stomach acid helps break them down) — which is why a GJ-tube (both ports) is ideal after an incision. (Bonus content, not on Exam 4.)
Q13 · How do you reduce aspiration risk with tube feeding?

✅ Answer

Raise the head of the bed, suction available, side-lying — anything that keeps feed from going down the throat. (Bonus content, not on Exam 4.)
Q14 · Difference between enteral and parenteral nutrition? (student question)

✅ Answer

Enteral = through the GI tract / tube feeding (activates the gut). Parenteral = TPN + lipids via IV, bypassing the gut. (Bonus content, not on Exam 4.)

🫘 Renal & Urinary Systems — Module 9 Deck

Slides 1–3 · Objectives, Topics & Urinary Elimination

Module topics: urinary diagnostics, incontinence, UTI, bladder cancer + diversion, renal diagnostics, pyelonephritis, glomerulonephritis, nephrotic syndrome, AKI, CKD, renal replacement therapies, PKD, renal calculi.

Factors affecting urinary elimination: poor abdominal/pelvic tone, acute & chronic disorders, spinal cord injury, older age, diet, immobility, psychological factors, pain, medications.

Slides 2–3 · Urinary Incontinence (6 types) HY

Types: Stress · Urge · Overflow · Reflex/Neurogenic · Functional · Transient.

Treatment: Stress → Kegels. Urge → pharmacotherapy. Overflow → often men w/ BPH; treat BPH, encourage complete emptying. Neurogenic → intermittent cath, bladder training. Functional → bladder training.

Reflex/Neurogenic bladder: from neuro disorders; spastic (empties on reflex, more common) or flaccid (fills + overflow). Tx: pharmacotherapy, bladder training, intermittent self-cath.

Slides 4–9 · UTI: Types, Risks, S/S, Diagnostics, CAUTI, Teaching HY

Types: urethritis (often STI) · cystitis (bladder) · pyelonephritis (kidney, complication of cystitis).

Risk factors: female anatomy, indwelling catheter (CAUTI), retention, stool incontinence, intercourse, pregnancy, synthetic underwear, hot tubs/wet clothing, neurogenic bladder, diabetes.

Manifestations: urgency/frequency, burning, suprapubic discomfort, cloudy/foul/blood-tinged urine; fever + flank pain = pyelonephritis; older adults → confusion, falls, fatigue, anorexia.

Diagnostics: urinalysis (clean catch), urine C&S, CT (pyelo).

CAUTI prevention: aseptic insertion, prevent backflow, bag below bladder, peri-hygiene, assess need daily, sterile closed system, drain before half full.

Teaching: antibiotics + antipyretics/analgesics, warm sitz baths, 3 L fluid/day, void q3–4h, void after intercourse, cranberry juice, wipe front-to-back, avoid bubble baths/perfumes/wet suits/tight synthetic clothing.

Slides 10–14 · Bladder Cancer & Urinary Diversion

Begins in cells lining the bladder; invasive or non-invasive. Risk: cigarette smoking (2× risk), male, older adults, occupational dyes/nitrates/rubber. #1 sign = gross, painless hematuria.

Diagnostics: cystoscopy with biopsy, CT.

Management: intravesical chemo, intravesical immunotherapy BCG (instilled, retained 2 h), systemic chemo, radiation, surgical excision (partial/total cystectomy).

Ileal conduit care: stoma & skin care, change pouch, measure I&O.

Slides 15–18 · Kidney Roles & Acid-Base HY

Kidney roles: fluid/electrolyte balance (esp. K⁺), waste removal, vitamin D activation (calcitriol), BP control, RBC production (erythropoietin), acid-base balance.

Kidneys balance pH by reabsorbing bicarbonate & secreting H⁺. Renal failure → metabolic acidosis (can't remove acids / hold bicarb).

Slides 19–22 · Renal Diagnostics, Biopsy, Pyelonephritis, Glomerulonephritis

Serum: BUN 8–20 (↑ with injury, dehydration, bleeding, hypotension); Creatinine 0.6–1.2 (better marker); GFR >90.

Biopsy: for cancer, unexplained AKI, transplant rejection → monitor renal function, assess for hemorrhage, analgesia.

Pyelonephritis: cystitis S/S + fever, chills, flank pain, N/V; may → sepsis, CKD, HTN. Tx: antibiotics, analgesia, 2 L fluids/day.

Glomerulonephritis: facial/hand/eye/foot edema, anorexia, N, dysuria/oliguria, fatigue, HTN, FVE, cola-colored urine. Mgmt: monitor renal fxn/BP/resp/fluids, antibiotics, possible protein/K⁺ restriction, maybe hemodialysis.

Slide 23 · Nephrotic Syndrome

Intrinsic glomerular damage. Manifestations: severe edema (pitting/periorbital), low albumin, proteinuria (foamy urine), hyperlipidemia. Tx: symptom management + treat underlying cause.

Slides 24–29 · AKI: Phases, Types, Manifestations, Management HY

Phases: Onset (hrs–days) → Oliguria (100–400 mL/24h, 1–3 wk) → Diuresis (large output, 2–6 wk) → Recovery (up to a year).

Manifestations: HTN, FVO, dysrhythmia, crackles/dyspnea, lethargy/twitching/seizures, dry skin; ↑BUN/creatinine, hyperkalemia, hyperphosphatemia, hypocalcemia, ↓Hct, metabolic acidosis.

Management: correct cause, monitor VS/labs/ECG, strict I&O, daily weights, manage FVE/FVD, diuretics, catheter for retention, restrict fluids PRN, BP mgmt, limit protein/K⁺/Na⁺/phosphate/Mg.

Slides 30–37 · CKD: Risks, Prevention, Manifestations, Labs, Management HY

Risks: AKI, diabetes, chronic glomerulonephritis, nephrotoxins, HTN (esp. Black clients), autoimmune (SLE), PKD, pyelonephritis, renal artery stenosis, recurrent infections.

Prevention: 2 L water/day, stop smoking, limit alcohol, manage weight/DM/HTN, adhere to meds, finish antibiotics, limit OTC NSAIDs.

Manifestations (mostly fluid overload): lethargy/confusion/seizures; JVD, edema, HTN, HF, peaked T-waves; uremic breath, Kussmaul breathing, crackles, pink frothy sputum; N/V; anemia & bruising; osteodystrophy; dry itchy pale-yellow skin, uremic frost; immunosuppression, poor wound healing.

Labs: hematuria/proteinuria, ↓ specific gravity, chronically ↑BUN/creatinine, ↓Na (dilutional) & ↓Ca, ↑K/phosphorus/Mg, ↓Hgb/Hct (low EPO).

Management: daily weight, review nephrotoxic meds, diet (limit protein, Na, K, Mg, phosphate; high complex carb, moderate fat), fluid restriction, monitor for infection. Pharmacotherapy: calcitriol, calcium carbonate, K⁺-lowering drug, ferrous sulfate, epoetin alfa, loop diuretic.

Slides 38–43 · Peritoneal Dialysis HY

Dialysate instilled via peritoneal catheter → dwell → drain → exchange. Advantages: fewer side effects, continuous/natural, better for older adults heart failure, fewer diet restrictions, home/while sleeping.

Types: CAPD (manual daytime exchanges) · continuous cycle (machine at night).

Nursing: warm dialysate (don't microwave), sterile technique, monitor glucose (dextrose dialysate), outflow bag below client/dialysate bag above; record outflow amount/color/clarity.

Complications: peritonitis (fever, pain, cloudy outflow — surgical asepsis!), site infection, protein loss, ↑ glucose/lipids, catheter blockage/dislodgement.

Slides 44–48 · Hemodialysis & Vascular Access HY

Shunts blood through dialyzer; 3×/week, 3–4 h. Removes fluid/electrolytes/waste, fixes acid-base — but doesn't replace hormonal function. Needs vascular access (artery + vein needles).

Access nursing: NO BP/IV/blood draws in access arm; palpate thrill, auscultate bruit; assess distal circulation & infection; check for bleeding post-HD; don't sleep on that arm.

HD nursing: hold most meds until after, pre/post weights, monitor BP (hypotension common), assess access, watch complications.

Complications: clotting/infection of fistula, disequilibrium syndrome (rapid fluid/BUN loss → cerebral edema; early N/V + HA, late ↓LOC/seizures → slow exchange rate), hypovolemia, anemia.

Slides 49–56 · Renal Transplant & NGN Case Study

Transplant: for ESKD; donors living/non-heart-beating/cadaver; living related + tissue match = best graft survival; lifelong immunosuppression to prevent rejection.

Case study labs: Peritonitis → ↑CRP, WBC, neutrophils. ESKD → ↑BUN/creatinine/K⁺/phosphorus, ↓Hgb (low EPO).

Slides 57–60 · Polycystic Kidney Disease

Autosomal dominant; fluid-filled cysts replace nephrons → enlargement → kidney failure. Most have HTN (cysts compress blood flow).

Manifestations: abd/flank pain (dull = enlargement/infection, sharp = ruptured cyst/stone), HTN, enlarged girth, constipation, bloody/cloudy urine, stones, hyponatremia, progressive failure.

Management: BP control = highest priority, pain mgmt (no NSAIDs), infection & constipation prevention, monitor labs, daily BP/weight, low-Na diet.

Slides 61–66 · Renal Calculi HY

Urolithiasis; most stones calcium phosphate/oxalate; most pass without surgery. Risks: stasis, retention, dehydration.

Manifestations: severe renal colic (worse as stone moves), frequency/dysuria, diaphoresis, pallor, N/V, tachycardia, ↑BP, oliguria/anuria if obstructing, hematuria.

Diagnostics: UA, KUB x-ray, ultrasound, CT, cystoscopy.

Management: opioids/NSAIDs (ketorolac)/antiemetics, strain all urine + save stone, ↑ intake to 3 L/day, moist heat, IV fluids, ambulation.

ESWL lithotripsy: moderate sedation + ECG; post: strain urine, expect bruising & hematuria. Complications: urosepsis, obstruction, hydronephrosis.

Diet: Calcium phosphate → limit animal protein & Na. Calcium oxalate → avoid spinach, black tea, cocoa/chocolate, beets, strawberries.

🫀 Hepatobiliary, Gallbladder & Pancreas — Module 10 Deck

Slides 2–7 · Objectives, Liver Functions & LFTs HY

Module topics: cirrhosis, viral hepatitis, liver failure, cholelithiasis, cholecystitis, pancreatitis.

Functions of the liver: glucose metabolism & glycogen storage, ammonia → urea conversion, protein & fat metabolism, vitamin/iron storage (fat-soluble vitamins + B12), bile formation, bilirubin excretion, drug metabolism, clotting-factor production.

Hepatic serum studies (LFTs):ALT (most liver-specific) AST in liver injury; ↑ALP = biliary obstruction; prolonged INR = poor synthetic function; ↑ammonia → hepatic encephalopathy; ↑bilirubin = jaundice; ↓albumin → ascites.

Liver biopsy: monitor INR, assess for hemorrhage, position on the right side after to apply pressure.

Slides 8–11 · Cirrhosis: Types, Risks & Manifestations HY

Irreversible scarring; functional tissue replaced by fibrosis. Types: alcoholic (most common), post-necrotic (viral hep B/C or toxins), biliary (chronic bile-duct obstruction, least common).

Risk factors: alcohol use disorder, chronic viral hepatitis, autoimmune hepatitis, steatohepatitis (fatty liver), hepatotoxic drugs/toxins, chronic biliary obstruction.

Slides 13–16 · Jaundice, Portal HTN & Ascites HY

Jaundice: yellowing of skin/sclera/mucous membranes; damaged liver can't process bilirubin (normal 0.3–1.0 mg/dL).

Portal hypertension: ↑ pressure in the portal venous system from obstructed blood flow through the damaged liver — drives ascites & varices.

Ascites: fluid in the peritoneal cavity from portal HTN + hypoalbuminemia (albumin 3.5–5.2 g/dL). Nursing priority = respiratory status. Mgmt: diuretics, strict Na restriction, paracentesis, TIPS shunt.

Slides 18–21 · Esophageal Varices HY

Enlarged esophageal veins from portal HTN; may rupture → life-threatening hemorrhage. Manifestations: hematemesis, melena, deterioration, hemorrhagic shock. Screen with endoscopy; treat with endoscopic ligation/banding.

Nursing: frequent VS, supplemental O₂, IV fluids/electrolytes/blood products, prevent aspiration, vasoactive drugs, prep for EGD/surgery. Bleeding risk ties to ↓ prothrombin & ↓ vitamin K storage.

Slides 23–30 · Viral Hepatitis A–E & Nursing HY

A — fecal-oral (contaminated food/water, shellfish); mild, full recovery; supportive care. E — fecal-oral, like A, poor-sanitation regions.

B — blood/body fluids, perinatal, sex; often silent; vaccine-preventable; no cure; risk of chronic hep, cirrhosis, liver cancer. D — only as coinfection with HBV.

C — blood/body fluids (IV drug use, needles, tattoos); often silent; direct-acting antivirals cure >90%; untreated → chronic liver disease, liver cancer.

Nursing: high-carb/high-cal, moderate-fat/protein, small frequent meals (hepatic rest); avoid alcohol; CDC vaccination & infection-control; hand hygiene; safe injection; purified water when traveling.

Slides 31–35 · Hepatic Failure & Acetaminophen Case Study

Hepatic failure: acute (sudden — infection, drug overdose, injury) vs chronic (gradual — cirrhosis/hepatitis). Tx: remove blood toxins, dietary changes, manage complications, possible liver transplant.

Case: 45 y/o male, acetaminophen overdose (suicide attempt) → N/V, abdominal pain, confusion; ↓BP, ↑HR/RR; ↑AST/ALT/bilirubin, prolonged INR. Recognize acetaminophen as the classic hepatotoxic overdose (antidote = acetylcysteine).

Slides 36–44 · Gallbladder: Cholelithiasis & Cholecystitis HY

Cholelithiasis = stones; cholecystitis = gallbladder inflammation, usually from stones obstructing ducts.

Risk factors — the 5 F's: Female, Fat (obesity), Forty+, Fertile (estrogen/OCPs/multiple pregnancies), Family history; also T2DM, Crohn, rapid weight loss, Native/Mexican American ethnicity.

Manifestations: RUQ pain radiating to right shoulder, worse after fatty foods; Murphy's sign; rebound tenderness, dyspepsia, belching; fever, leukocytosis; ↑bilirubin, jaundice, clay-colored stools, dark urine.

Diagnostics: ultrasound, HIDA scan, ERCP (NPO 6–8 h before, moderate sedation, withhold fluids until gag reflex returns; risk of pancreatitis). Mgmt: laparoscopic cholecystectomy (home in 24 h); open approach may need a T-tube (removed in 2–4 wks) & JP drain.

Slides 45–54 · Pancreatitis HY

Pancreatitis: autodigestion by prematurely activated enzymes → inflammation, necrosis, hemorrhage. Acute: 80% from gallstones or alcohol. Chronic: progressive fibrosis → diabetes + malabsorption.

🍎 Nutrition (Modules 9 & 10)

Diet therapy for Renal/Urinary & Hepatobiliary disorders · ATI Nutrition Ch. 14–15

Big picture: Two dials dominate this exam's nutrition — protein (the renal "flip") and fat (the hepatobiliary lever). Nail those two and most questions fall into place.

🫘 Renal & Urinary Nutrition (Module 9)

Urea is the waste product of protein metabolism. It rises as kidneys fail, so protein is the master dial — but which way you turn it depends on dialysis.

CKD Stages 1–4 (pre-dialysis)

ESKD / Stage 5 — the protein FLIP

On dialysis, protein INCREASES to 1.0–1.2 g/kg (amino acids are lost in the dialysate). Still low sodium (2–3 g), low potassium, low phosphorus (700–1,200 mg), fluid-restricted, ~35 kcal/kg, phosphate binders with meals.

Acute Kidney Injury (AKI)

Usually reversible. 20–30 cal/kg. Protein 0.6 g/kg (no dialysis) → 1.0–1.2 (on dialysis). Fluid = urine output + 500 mL when oliguric.

Nephrotic syndrome

Proteinuria + edema. Adequate protein 0.7–1.0 g/kg (soy helps), LOW sodium (2,000 mg), carbs for calories, low cholesterol/fat, vitamins.

Kidney stones

Mostly calcium oxalate. #1 = FLUIDS for ≥2 L urine/day (including before bed). Limit animal protein, sodium, and oxalates (spinach, rhubarb, beets, nuts, chocolate, tea). No megadose vitamin C.

🫀 Hepatobiliary, Pancreatic & Biliary Nutrition (Module 10)

Liver disease

Protein (positive nitrogen balance) · carbs NOT restricted · vitamins B, C, K · eliminate alcohol, nicotine, caffeine. (In hepatic encephalopathy, protein is temporarily moderated — but the default liver-diet answer is higher protein.)

Cholecystitis (gallbladder)

LIMIT fat — dietary fat stimulates the inflamed gallbladder. Low-fat is the whole answer.

Pancreatitis

🍽️ Related GI Nutrition (supporting)

ConditionDiet answer
Low- vs high-fiberLow-fiber RESTS the gut (diarrhea, flares); high-fiber MOVES it (constipation, prevention).
ConstipationFiber 25 g/day female · 38 g/day male; fluids 64 oz/day; exercise. Avoid chronic laxatives.
DiarrheaReplace fluid + potassium + sodium; low-fiber short-term.
Dysphagia (aspiration risk)Sit UPRIGHT / high-Fowler's, thicken liquids, avoid thin liquids & sticky foods.
Dumping syndromeEarly 10–20 min (vasomotor) · late 1–3 hr (rebound HYPOglycemia). Small frequent meals, protein + fat, NO concentrated sugar, fluids between meals.
GERDNo eating 3 hr before lying down; elevate on pillows; avoid citrus, spicy, carbonated, fatty, caffeine, chocolate, alcohol, mint, nicotine.
Celiac diseaseStrict gluten-free FOR LIFE — the only treatment. Safe: rice, corn, potato, meat, fruit.
OstomyFluid & electrolytes #1 (64–80 oz + soluble fiber); ↑ protein/calories to heal.
IBD (Crohn's/UC) flareLow-residue, high-protein, high-calorie + vitamins; enteral before parenteral.

🩺 Dialysis Infection Case Studies

NGN case study + bowtie · PD peritonitis & HD access sepsis

📋 Case 1 — PD Peritonitis

35F · ESRD · automated peritoneal dialysis × 6 months. Fever, vomiting, abdominal pain × 1 day. T 39.1 °C, HR 104, RR 16, BP 145/87. Periumbilical tenderness with guarding & rebound. Erythema + creamy yellow exudate at PD catheter exit site. Cloudy yellow dialysate effluent.

Bacteria entered through the catheter exit site → infected the peritoneum → now she's at risk of going septic. That's the whole story.

The 5 most concerning findings

BUN and creatinine are sky-high — but she has ESRD. That's her baseline, not the emergency. Never pick chronic findings when there's an acute infection on the table.

🧪 Peritonitis vs. ESRD — sorting the labs

FindingPeritonitisESRD
BUN 46 mg/dL
Creatinine 11.7 mg/dL
C-reactive protein 61.5 mg/L
Potassium 5.86 mEq/L
Phosphorus 5.4 mg/dL
Hemoglobin 10.6 g/dL
WBC 14.22
Neutrophils 89%
Sort it in one move — infection markers (CRP, WBC, neutrophils) → Peritonitis. Failed-kidney chemistry (BUN, creatinine, K⁺, phos, low Hgb) → ESRD.

CRP in 30 seconds

Baseline caveat

ESRD patients run a mildly elevated CRP (~5–10) from chronic inflammation. Hers is 61.5. That's acute infection, not noise.

⚡ Highest risk for developing…

SEPSIS

The peritoneum is a huge, highly vascular surface — bacteria there reach the bloodstream easily. She already has fever, tachycardia, high WBC, high CRP. The systemic response has started.

Why not the others

  • Abdominal abscess — possible, but slower and less lethal
  • Cellulitis — she already has it. That's the cause, not the future risk
  • Pyelonephritis — ESRD. Kidneys aren't making urine. Wrong organ

The rule

"Highest risk" = what kills her fastest. On the NCLEX that's almost always sepsis.

💊 Orders — appropriate or not?

Culture result: gram-negative rods.

OrderVerdictWhy
Daily weightsYESOnly reliable fluid-status measure in someone who doesn't urinate
Blood cultures STATYESHigh sepsis risk — draw before antibiotics
PD catheter care Q shiftYESThe exit site is the source
IVF D5½NS + 20 mEq KCl @ 120 ml/hrNOMost dangerous order here. K⁺ already 5.86, and she can't excrete potassium or that volume
Calcium carbonate with mealsYESPhosphate binder — phos high, Ca low. Fixes both
Vancomycin IVNOVanc covers gram-POSITIVE. Culture is gram-NEGATIVE. Wrong drug
Gentamicin intraperitoneally dailyYESCovers gram-negative, delivered right where the infection lives
Enoxaparin subQ dailyNORenally cleared → accumulates in ESRD → bleeding risk
Epoetin alfa injectionsYESHgb 10.6 — failed kidneys make no erythropoietin
The gram stain drives the antibiotic. Gram-NEGATIVE rods → aminoglycoside/cephalosporin (gentamicin). Gram-POSITIVE cocci → vancomycin. Swap them and you kill nothing.

👥 Delegation — RN / LPN / UAP

TaskWhoWhy
Vital signsUAPRoutine data collection, no judgment required
Daily weightsUAPSame — but the RN still interprets the number
Dialysate exchangeLPNSterile procedure with a defined protocol
PD catheter care Q shiftLPNSterile procedure on a direct line into the peritoneum
Intraperitoneal gentamicinRNMed into a sterile body cavity + nephro/ototoxic drug
PD catheter care teachingRNTeaching is never delegated
Catheter care is NOT a UAP task. It's a sterile procedure into the peritoneal cavity — LPN/RN scope only. Marking UAP is wrong on the NCLEX and a scope violation on the floor. It's exactly how patients get peritonitis in the first place.
The rule that answers every delegation question: RN keeps Assessment, Teaching, Evaluation, unstable/high-risk meds. LPN gets sterile procedures with a set protocol. UAP gets routine data collection and ADLs. See the word "teach"? → RN. Always.

🗣️ Exit-Site Care Teaching — understands or not?

Client statementVerdict
"I'll wash my hands with soap and water and put on clean gloves."UNDERSTANDS
"I should remove crusts or scabs at the exit site before washing."DOES NOT
"I should hold the catheter in place during cleaning."UNDERSTANDS
"I should scrub the exit site vigorously with iodine or chlorhexidine."DOES NOT
"I'll put antibiotic cream around the catheter every dressing change."UNDERSTANDS
"I won't use petroleum creams — they damage the catheter."UNDERSTANDS
"I'll leave the exit site open to air or covered by loose clothing."DOES NOT

Why the wrong ones are wrong

  • Picking scabs — that's a scab over a healing tract. Rip it off = direct highway into the peritoneum.
  • Vigorous scrubbing — trauma causes infection. Clean gently, clean around crusts.
  • Open to air — the site needs a sterile dressing and the catheter must be anchored. Loose clothing immobilizes nothing; tension pulls the tunnel open.
Theme for every exit-site answer: gentle + covered + anchored. Anything that traumatizes the site or lets the catheter move = wrong answer.

🎀 Case 2 — HD Access Sepsis (Bowtie)

39M · ESRD secondary to heroin nephrotoxicity · hemodialysis × 7 months. Shaking chills, fever. Left upper arm AV fistula with positive thrill and bruit, but red and inflamed.

Read the trend, not the snapshot

BP dropped 50 points in one hour while HR climbed. That's not "infected fistula." That's septic shock starting.

Bowtie answers

✅ Actions to Take

  • Administer oxygen
  • Administer broad-spectrum antibiotics IV

🎯 Condition

SEPTICEMIA

📈 Parameters to Monitor

  • Blood pressure
  • Pulse oximeter
URINARY OUTPUT. In any other sepsis question it's a correct answer. Here he's on hemodialysis — he barely makes urine. Useless parameter. Always check whether the "obvious" answer still applies to THIS patient.

Why not the other options

Wrong actions

  • Epinephrine drip — vasopressors come after fluids, and norepinephrine is first-line in sepsis anyway
  • Prepare for intubation — premature. 90% isn't intubation territory. Give O₂ first
  • Raise HOB — positioning/comfort, not treatment

Wrong conditions / parameters

  • Cardiogenic shock — no cardiac event
  • ARDS — no bilateral infiltrates or refractory hypoxemia yet
  • MODS — organs haven't failed yet. Sepsis comes first
  • Pain / liver enzymes — not sepsis progress markers
History of IV heroin use + vascular access infection = screaming risk for Staph aureus bacteremia and endocarditis. Listen for a new murmur.
