NCLEX Pediatric Nursing: High-Yield Topics and Study Guide
Pediatric nursing on the NCLEX requires you to think differently about assessment, medication dosing, and communication. Children are not small adults — their physiology, developmental stage, and psychosocial needs are unique. This guide covers the topics most frequently tested on the exam.
Growth and development milestones are heavily tested
Know the key milestones by age: social smile at 2 months, sits unsupported at 6 months, walks at 12 months, speaks 2-word sentences at 2 years. Erikson's stages are also tested — trust vs. mistrust (infant), autonomy vs. shame (toddler), initiative vs. guilt (preschool), industry vs. inferiority (school age).
Vital Signs by Age
Pediatric vital signs differ significantly from adults. Heart rate: newborn 120–160, infant 100–150, toddler 80–130, school age 70–110. Respiratory rate: newborn 30–60, infant 25–40, child 20–30. Blood pressure increases with age — hypotension is a late sign of shock in children. Fever in an infant under 3 months (≥100.4°F / 38°C) is always an emergency.
Medication Safety in Pediatrics
All pediatric medications are dosed by weight in mg/kg. Always verify the weight is in kilograms — never assume. Calculate the safe dose range before administering any medication. If the ordered dose exceeds the safe range, clarify with the provider before giving it.
Avoid aspirin in children due to the risk of Reye's syndrome (use acetaminophen or ibuprofen instead). Codeine is contraindicated in children under 12. When administering IM injections to infants, use the vastus lateralis muscle — the deltoid is too small.
Common Childhood Diseases
Croup: seal-bark cough, inspiratory stridor, worse at night. Treat with cool mist humidifier or exposure to cool night air. Severe cases require nebulized racemic epinephrine and dexamethasone. Epiglottitis: sudden onset of high fever, drooling, tripod positioning. This is a medical emergency — do not inspect the throat (risk of complete airway obstruction). Prepare for intubation.
Kawasaki disease: high fever lasting 5+ days, strawberry tongue, conjunctivitis, rash, swollen hands/feet, and cervical lymphadenopathy. Treat with IV immunoglobulin and high-dose aspirin (one of the few times aspirin is used in pediatrics). Monitor for coronary artery aneurysms.
Dehydration assessment is critical in children
Children dehydrate faster than adults due to their higher body surface area to weight ratio. Assess for decreased urine output (fewer wet diapers), sunken fontanels in infants, dry mucous membranes, poor skin turgor, and lethargy. Mild dehydration: oral rehydration. Moderate to severe: IV fluid resuscitation with isotonic saline.
Pediatric Emergencies
Respiratory distress is the most common pediatric emergency. Signs include nasal flaring, intercostal retractions, grunting, and head bobbing in infants. Respiratory failure progresses quickly in children — early recognition is critical. For choking: infants get 5 back blows and 5 chest thrusts; children over 1 year get abdominal thrusts (Heimlich maneuver).
Febrile seizures occur in children 6 months to 5 years with high fevers. They are typically self-limiting and last less than 15 minutes. Priority: ensure safety (protect from injury, position on side), do not restrain, time the seizure, and reassure the parents afterward.
Family-Centered Care
Always include parents in the plan of care. Use age-appropriate communication — dolls and play for toddlers and preschoolers, clear explanations for school-age children. Therapeutic play (letting a child give an injection to a doll) helps reduce anxiety before procedures. Informed consent comes from the parent/guardian, but children over 7 should be given age-appropriate assent.
In pediatric nursing, you always have two patients — the child and the family. Addressing parental anxiety and providing thorough education are just as important as the clinical intervention itself.
