A seizure is a sudden, uncontrolled burst of electrical activity in the brain. Most stop
on their own in under two minutes — so almost nothing you are tested on is about stopping it. It
is about keeping the airway open and the patient uninjured while it runs, and knowing the exact minute
it stops being a seizure and becomes status epilepticus.

TYPES & PHASES
STEP 1 · CLASSIFY
Two questions sort every seizure: how much of the brain is involved, and what stage are we watching right now.
🧠 Generalized vs focal — how much brain is involved
🧠 GENERALized = the whole GENERAL area. FOCAL = one FOCUS. If consciousness is lost from the very start, think generalized.
🌍 The generalized types
Tonic–clonic (“grand mal”) — stiffen then jerk, loss of consciousness. The one everyone pictures.
Absence (“petit mal”) — brief blank staring, often in children; mistaken for daydreaming or inattention.
Myoclonic — sudden brief jerks of a limb or the whole body.
Atonic (“drop attack”) — all tone lost, the patient falls. Helmets are a real intervention.
Tonic or clonic alone — stiffening only, or jerking only.
🧠 Absence seizures look like a child ignoring you. A teacher’s report of “stares off, then carries on mid-sentence” is the classic stem.
📍 The focal types
Focal AWARE (old name: simple partial) — patient stays awake and can remember it. Symptoms match the lobe: jerking of one hand, a strange smell, tingling.
Focal with IMPAIRED AWARENESS (old: complex partial) — altered awareness, staring, and automatisms: lip smacking, picking at clothes, fumbling.
Focal to bilateral tonic–clonic — starts in one place and spreads to the whole brain.
🧠 Automatisms = the body on autopilot. Lip smacking and clothes picking during a staring spell is focal, not absence.
🧠 “PATCH-P”: Prodrome, Aura, Tonic, Clonic, then Postictal. The whole convulsion is usually under two minutes; the postictal phase is the long part.
⭐ The AURA is a warning, not a symptom to fix
An aura is an unusual sensation immediately before the seizure — a smell, a taste, a rising
feeling in the stomach, a flash of light, déjà vu.
Classic stem: the client says “I smell oranges and there aren’t any on my tray.” The best
response is “Have you experienced this sensation before?” — you are establishing whether this
is their usual aura, because if it is, a seizure is about to happen and you have seconds to make them
safe.
🧠 An aura is a free warning. Teach patients that when they feel theirs, they should sit or lie down immediately.
🧨 What triggers seizures
Missed or abruptly stopped antiseizure medication — the number one cause
🧠 Check the glucose and the sodium. Two cheap labs explain a surprising number of first seizures.
🎭 Not every “seizure” is a seizure
Events that look like seizures but are not epileptic: syncope (brief jerks after fainting),
psychogenic non-epileptic events, breath-holding spells in toddlers, migraine aura, and
transient ischemic attacks.
Clues that point away from a true seizure include a gradual onset, eyes held tightly closed, side-to-side
head shaking, very long duration with normal oxygen saturation, and no postictal confusion.
Treat the patient safely either way — the diagnosis is made on video EEG, not at the bedside.
🧠 No postictal phase is the biggest clue. A real tonic–clonic seizure leaves the patient wrecked afterwards.
⚠️ “Seizure” vs “epilepsy”
A seizure is a single event — anyone’s brain can have one under enough provocation.
Epilepsy is a chronic disorder of recurrent unprovoked seizures. A febrile seizure or a
seizure from hypoglycemia is not epilepsy.
🧠 One provoked seizure ≠ epilepsy. Fix the provocation first.
🩺
DURING THE SEIZURE
STEP 2 · DO
This is the highest-yield section on the page. If you learn one thing here, learn the order — and the three nevers.
✅ The bedside picture
🧠 “SIDE · PAD · TIME · STAY.” Four words that answer most “what does the nurse do first” questions about an active seizure.
✅ Priority order at the bedside
1
AIRWAY — turn the patient onto their SIDE. Gravity drains saliva, blood and vomit away from the airway. This is the single most important action.
2
Protect the head — pillow, folded blanket, or your hands. Move furniture and hard objects away.
3
Call for help and STAY. Use the call bell rather than leaving the room.
4
TIME it. Note the exact start time — the treatment changes at 5 minutes.
5
Loosen restrictive clothing at the neck and chest.
6
Prepare for suction and oxygen; lower the bed and raise the padded rails if the patient is in bed.
7
Observe and remember the details — you are the only witness.
🧠 Airway beats everything. If “turn the client to the side” is an option during an active seizure, it is almost always the answer.
❌ THE THREE NEVERS
Never insert anything into the mouth · never restrain or hold down the limbs · never leave the patient alone.
People cannot swallow their tongue. Forcing an object between clenched teeth breaks teeth, damages the
airway and gets you bitten. Holding a convulsing limb causes fractures and dislocations — guide
movements away from hazards instead of gripping.
🧠 “Nothing in, nobody holds, nobody leaves.”
👀 What to observe — you are the witness
The chart is the diagnostic test. Record:
Time started and time stopped — exact, not “a few minutes”
What the patient was doing immediately before; any aura reported
Where it started and whether it spread (focal → generalized)
Which body parts moved, and whether movement was symmetrical
Eye deviation, pupil size, head turning
Color — cyanosis, apnea
Incontinence of urine or stool; tongue or cheek biting
Level of consciousness during and after; duration of the postictal phase
🧠 “Where it starts tells you where the lesion is.” That is why “which side jerked first” matters more than it sounds.
⭐ If the seizure happens out of bed
Ease them to the floor — do not try to lift or move them onto the bed
Something soft under the head; clear the area
Roll onto the side as soon as the jerking allows
Nothing under the head that could obstruct breathing — a thin pillow or folded clothing, not a bulky cushion
Stay, time it, and get help
🧠 Down, soft, side, stay. Same four moves, wherever they are.
🚨
STATUS EPILEPTICUS
STEP 3 · EMERGENCY
A seizure that will not stop is a medical emergency — the brain is burning oxygen it cannot replace.
🚨 The definition and the escalation ladder
🧠 “Five and it’s alive.” Five minutes of continuous seizure and it will not stop on its own — it needs a drug.
💊 The #1 drug: a benzodiazepine
After the airway and breathing are secured, the priority is to STOP the seizure. The
first-line agents are benzodiazepines:
Lorazepam (brand: Ativan) — IV
Diazepam (brand: Valium) — IV or rectal gel when there is no IV access
Midazolam — intramuscular or intranasal when there is no IV access
Watch for the side effects: respiratory depression, hypotension and sedation. Have a bag-valve
mask and monitoring in place before you push.
💊 Benzos BREAK the seizure but they also SLOW the breathing. Never give one without the airway equipment at the bedside.
⚠️ Why it is dangerous
Hypoxia — the patient is not ventilating effectively while convulsing
Hyperthermia from sustained muscle activity
Lactic acidosis, rhabdomyolysis and acute kidney injury
Aspiration
Permanent neuronal injury — neurons die from the metabolic demand
Fractures and dislocations from the convulsion itself
🧠 The brain is running a sprint it cannot stop. Every extra minute costs neurons.
🧪 Look for the cause while you treat
Blood glucose — checked immediately; hypoglycemia both mimics and prolongs seizures
Electrolytes — sodium, calcium, magnesium
Antiseizure drug levels — a subtherapeutic phenytoin level often explains the whole event
Toxicology, alcohol withdrawal history
Oxygen saturation and capnography
CT head once stable if the cause is unclear
🧠 “Did they take their medication?” is the most productive question in the room.
⭐ The most common cause of status is an abrupt medication stop
Never stop an antiseizure medication abruptly — not for a procedure, not because the patient feels better, not because they ran out.
Doses are tapered over weeks under a provider’s direction. Teach patients to:
Refill before running out and never skip doses
Carry a medical alert ID
Tell every prescriber and dentist what they take
Call the provider rather than stopping if side effects appear
🧠 “Stopping suddenly is how a controlled epileptic ends up intubated.” Say it exactly like that and you will never miss the question.

AFTER THE SEIZURE & PRECAUTIONS
STEP 4 · RECOVER
The postictal patient is confused, exhausted and at risk. And the padding should have been up long before any of this.
✅ Postictal care
1
Keep them side-lying and suction as needed — secretions are the airway risk now.
2
Assess LOC, neuro status and vital signs; check oxygen saturation and give oxygen as needed.
3
Check for injuries — head, tongue, shoulders, hips; check for incontinence and provide hygiene privately.
4
Reorient calmly and repeatedly. They will not remember the seizure and may be frightened or combative.
5
Let them sleep. Deep postictal sleep is normal — keep the rails up and the bed low.
6
Document everything and notify the provider.
🧠 Postictal confusion is expected. Postictal FOCAL WEAKNESS is not — a lasting one-sided weakness (Todd’s paralysis) needs reporting.
😴 What the postictal phase looks like
Deep sleep, difficult to rouse — minutes to hours
Confusion and disorientation, sometimes agitation
Headache and generalized muscle soreness
No memory of the event at all
Possible temporary weakness on one side
Document this phase by name: “documented as the postictal phase.”
🧠 “Post-ictal” = after the ictus (the seizure itself). Ictal = during, interictal = between.
📝 How to document it
Write it so someone who was not there can classify the seizure:
“At 1412 client reported an odd smell, then had
tonic–clonic activity beginning in the right arm and spreading to all four limbs (focal onset, becoming bilateral). Eyes deviated left.
Cyanosis noted. Turned to left side, airway maintained, O₂ 2 L nasal cannula
applied, side rails padded and up. Activity stopped at 1413:40
(100 seconds). Incontinent of urine. Postictal, deeply asleep, rousable to
voice at 1425, oriented to person only. Vital signs …. Provider notified.”
🧠 Onset · spread · duration · airway · postictal. Five elements and the note writes itself.
🛏️ Seizure precautions — set up BEFORE anything happens
🧠 “Low bed, up rails, suction & O₂, clear floor.” If a stem asks what you set up for a new admission with a seizure history, that is the list.
⚠️ Everyday safety teaching
Showers, not baths — a seizure in a bath is a drowning risk
Never swim alone; supervision at all times in water
No driving until the legally required seizure-free interval is met — and clearance comes from the provider, not the nurse
Avoid working at heights, with open flame, or with dangerous machinery
Avoid known triggers: sleep deprivation, alcohol, flashing lights if photosensitive
Medical alert bracelet at all times
Teach family what to do — and what never to do — during a seizure
🧠 Water and heights are the two killers. The seizure itself rarely is.
👨👩👧 Teach the family — and when to call 911
Stay calm, time it, protect the head, turn them on their side
Nothing in the mouth, no restraints, do not leave them
Move furniture away; take glasses off; loosen anything tight at the neck
Stay with them until they are fully awake and oriented
Call emergency services if: the seizure lasts > 5 minutes · a second
seizure follows without recovery · the patient does not wake up · breathing is difficult · it happened in
water · they are injured, pregnant, or diabetic · it is their first seizure.
🧠 Five minutes, second seizure, doesn’t wake up, in water, first ever. Any one of those = call.
🤰 Pregnancy and antiseizure drugs
Several antiseizure medications are teratogenic — valproic acid in particular carries a high
risk of neural tube defects and is generally avoided in people who could become pregnant.
Carbamazepine also carries risk.
Teach that a pregnancy must be planned with the prescriber, that folic acid supplementation is
routinely recommended, and that the medication is never stopped without medical advice — an
uncontrolled seizure is dangerous for both mother and fetus.
💊 “Val is bad for the belly.” Valproate + pregnancy is the classic exam pairing.
✅ When drugs are not enough
Ketogenic diet — high fat, very low carbohydrate; used mainly in refractory pediatric epilepsy and requires dietitian supervision
Vagus nerve stimulator — an implanted device; the patient can swipe a magnet over it when an aura starts
Responsive neurostimulation / deep brain stimulation
Epilepsy surgery — resection of a well-localized focus after video EEG mapping
🧠 Refractory = two appropriate drugs failed. That is the point at which these options get considered.
🧊 A note on febrile seizures
Common in children roughly 6 months – 5 years, triggered by a rapid rise in
temperature. Most are brief, generalized and do not cause brain damage.
Teach parents: control fever with antipyretics as directed, keep the child safe and side-lying during
the event, and do not use ice baths or alcohol rubs — rapid cooling causes shivering, which raises
the temperature again.
🧠 Reassure, don’t over-treat. Most children with febrile seizures never develop epilepsy.

DRUGS & DIAGNOSTICS
STEP 5 · TREAT
Know the names, the one big monitoring point for each, and the rule that applies to every single one of them.
🚨 The rule that applies to every antiseizure drug
Never stop an antiseizure medication abruptly.
Abrupt withdrawal precipitates status epilepticus. Doses are tapered slowly. This is true of
all of them, and it is the most commonly tested single fact about the class.
💊 One rule, every drug. If an answer option says “stop the medication,” it is wrong unless a provider ordered a taper.
💊 The drugs by name
Drug
The thing you monitor / teach
Phenytoin (Dilantin)
Therapeutic level commonly cited as 10–20 mcg/mL (a typical adult range that varies by lab); hold and report above 20. Gingival hyperplasia — meticulous oral care and dental visits. Nystagmus is an early toxicity sign. IV: mix with normal saline only (precipitates in dextrose) and infuse slowly.
Fosphenytoin
A prodrug of phenytoin used IV/IM in emergencies; fewer infusion-site problems, still monitor cardiac rhythm and blood pressure.
Levetiracetam (Keppra)
Well tolerated; watch for mood and behavior changes — irritability, agitation, depression. Driving permission comes from the provider.
Carbamazepine (Tegretol)
Blood dyscrasias (agranulocytosis, aplastic anemia), Stevens–Johnson syndrome, hyponatremia, many interactions. Report sore throat, fever, bruising or rash.
💊 PHENytoin = PHEN-cy gums. Levetiracetam = “Keppra makes you kranky.” Valproate = “Val hurts the liVer.” Lamotrigine = “Lamo-RASH-gine.”
🧪 Phenytoin level — the number you must recognize
A reported level of 22 mcg/mL means hold the dose and notify the
provider. Do not give it and document later.
10–20 mcg/mL is the commonly cited therapeutic range for total serum phenytoin; it is a typical adult reference range and varies by laboratory (and free/unbound levels use a different range) — always check the range reported with your patient’s result.
🧠 10 to 20 is fine. Over 20 you’re done.
📈 EEG and imaging
🧠 EEG = the EGG head (Electrical activity of the brain). ECG = C for Cardiac. Two letters apart, two completely different tests.
🖼️ The other diagnostics
CT head — first-line after a new seizure to exclude bleed, tumor or trauma
MRI — better for structural lesions and mesial temporal sclerosis
Blood glucose, electrolytes, calcium, magnesium
Antiseizure drug levels and a toxicology screen
Lumbar puncture if infection is suspected
🧠 A first seizure in an adult always earns imaging. The seizure is a symptom, not the diagnosis.
🎯 NCLEX traps on this topic
The stem says…
The answer is…
“Client is actively seizing — first action?”
Turn the client to the side (airway)
“Which action does the nurse take during a seizure?”
Protect the head / clear the area — never insert anything, never restrain
“I smell oranges and there aren’t any on my tray”
“Have you experienced this sensation before?” — that is an aura
“Deep sleep and confusion after the event — documented as?”
The postictal phase
“Seizure has lasted 6 minutes”
Status epilepticus — airway, then IV/rectal benzodiazepine
“Phenytoin level is 22 mcg/mL”
Hold the dose and notify the provider
“Preparing for an EEG — which instruction?”
No caffeine for 12–24 h · wash the hair · eat beforehand (not NPO)
“Client on levetiracetam asks about driving”
Driving permission must come from the provider
“Client feels better and wants to stop the medication”
Never stop abruptly — it causes status epilepticus
“Safe bathing for a client with epilepsy?”
Take showers rather than baths
🧠 Side · protect · time · never stop the drug. That covers most of the exam’s seizure questions.
