💉 Pediatric Medication Administration

Everything is weight-based and double-checked. Sites, volumes, and how to get a toddler to take it.

⚖️ The safety rules

The same child weighed in pounds and in kilograms, and the 2.2-times overdose that follows if the two are confused, with the injection sites by age and the maximum volume each takes.
Weigh in kilograms only. Recording pounds and treating them as kilograms is a 2.2-times overdose every single time. Swipe it sideways if it is cut off, or tap to open it full size.

Pediatric doses are calculated, not looked up. A tenfold error is easy to make and can be fatal, which is why every step is checked twice.

Weigh in KILOGRAMS only. Recording pounds and treating it as kilograms is a 2.2-times overdose, and it has killed children.

🧠 Checking a dose

  • Dose is mg per kg — know the safe range before you draw it up
  • Independent double-check by a second nurse for high-alert drugs: insulin, opioids, chemotherapy, digoxin, anticoagulants
  • If the calculated dose seems large or small, recalculate before questioning the child, not after
  • Use oral syringes for liquids, never a kitchen spoon
  • Two identifiers — and in pediatrics, ask the parent to confirm the name too
RouteSiteMax volume per site
IM — infantVastus lateralis0.5–1 mL
IM — toddler/childVastus lateralis; deltoid once walking well1–2 mL
IM — adolescentDeltoid or ventrogluteal2–3 mL
SubcutaneousAbdomen, thigh, upper arm0.5 mL

The dorsogluteal site is not used in children who are not yet walking - the muscle is undeveloped and the sciatic nerve is close.

🩺 Getting it into the child

✅ By age

  • Infant — small amounts into the side of the cheek with an oral syringe; let them swallow between. Never squirt into the back of the throat
  • Toddler — offer two acceptable choices: which cup, sitting on whose lap. Never ask “will you take it?”
  • Preschooler — brief honest explanation; let them hold the syringe; a sticker afterwards
  • School age — explain what it does; let them choose the order
  • Adolescent — privacy, and involve them in the decision

🚨 Things not to do

  • Never call medicine "candy" or "candy" - children then seek it out unsupervised.
  • Never mix medicine into a full bottle of formula or a whole meal. If it is not finished, the dose is unknown.
  • Never tell a child an injection will not hurt. Say it will hurt for a moment and that they can hold your hand.

A small amount of a strongly flavored food is acceptable if the drug allows it — check first, because some are inactivated.

💊 Comfort during procedures

  • Topical anesthetic cream where time allows
  • Sucrose and non-nutritive sucking for infants; breastfeeding during the procedure works well
  • Swaddle; hold the child upright on a parent’s lap rather than lying flat — it is far less frightening
  • Distraction: bubbles, a phone, counting, a favorite song
  • Do painful procedures in a treatment room, never in the child’s bed — the bed must stay a safe place

🎯 NCLEX traps

  • Kilograms only
  • Vastus lateralis for infants; max 1 mL
  • Two choices, not an open question, for a toddler
  • Never in a full bottle; never called candy
  • Painful procedures happen in the treatment room
