1The ten rights
Drug · patient · time · route · dose
Approach · documentation · form
Pediatrics adds right approach (developmental technique), right form, and the child's right to be educated and right to refuse to the adult five.
2How kids' bodies handle drugs
Pharmacodynamics = drug → body
Pharmacokinetics = body → drug (ADME)
Kids: more body water, less fat, less protein binding (more free drug), immature blood-brain barrier, immature kidneys → longer half-life, more toxicity risk. Absorption is less predictable in infants.
3Dosing safety
Weight in KILOGRAMS · current · accurate
Check pediatric range + MAX dose
Doses by mg/kg or body surface area (mg/m²). Pounds used as kilograms more than doubles the dose. Independent double-checks; monitor response.
4Ear drops + oral meds
Under 3 yrs: pinna DOWN and back
3 yrs and up: pinna UP and back
Eye drops go in the lower conjunctival sac; never touch the eye with the dropper. Oral liquids: oral syringe, slowly inside the cheek, never force a crying child.
5Injection sites
Infants: vastus lateralis (outer thigh)
Older kids: deltoid · ventrogluteal selected
Choose by age, muscle development, volume. Subcutaneous = insulin. Intradermal = diagnostic tests. Always atraumatic technique.
6Meds through feeding tubes
Verify placement FIRST
Never crush extended-release or enteric-coated
Crushing extended-release dumps the whole dose at once; crushing enteric-coated destroys its protection. Prefer liquids, give meds separately, flush per orders.
7IV therapy in children
Small fragile veins · tiny fluid volume
Scalp veins OK in neonates
Sites: hands/forearms, feet in selected infants, scalp in neonates. Use a pump, verify rate + volume — but never rely on pump alarms alone. Prep equipment before approaching the child.
8Maintenance fluids — 100/50/20
First 10 kg: 100 mL/kg/day
Next 10 kg: 50 · over 20 kg: 20
Example: 25 kg = 1,000 + 500 + 100 = 1,600 mL/day. Monitor: prescribed vs actual volume, intake/output, diaper weights, urine in mL/kg/hr, daily weight.
9IV complications
Infiltration: cool · swollen · blanched · leaking
Extravasation: vesicant leak = tissue injury
Phlebitis (vein inflammation): red, warm, tender. Infection: redness, drainage, fever. Overload: edema, breathing changes, weight gain. Remove lines when no longer needed.
10Enteral feeding safety
Enteral preferred when the gut works
NEMU measurement preferred over NEX
Never trust air auscultation alone — it can sound right with the tube in the lung. Never feed when placement is uncertain. NG/OG short-term; G-tube/J-tube long-term. Coughing + distress mid-feed? Stop, assess airway first.
11TPN essentials
TPN = complete nutrition · central line
PPN = short-term · peripheral · dilute
Never stop TPN abruptly — insulin outlasts the glucose and blood sugar crashes. Monitor glucose, electrolytes, weight, line site. Strict aseptic technique.
