NCLEX-PN pediatrics: development, immunisations, and common childhood conditions

Developmental milestone knowledge helps the LPN/LVN identify children who may need referral and choose age-appropriate communication strategies.

Red flag developmental delays requiring reporting: No social smile by 3 months, no babbling by 12 months, no single words by 16 months, no 2-word phrases by 24 months, any loss of previously acquired language or social skills at any age, no pointing by 12 months.

Age-appropriate communication: Infants/toddlers: involve parents, use simple words and visual cues, allow security objects. Preschool: explain procedures immediately before (not hours ahead — increases anxiety), use puppets/dolls to demonstrate, offer limited choices for control. School-age: explain honestly in concrete terms, allow questions, privacy becomes important. Adolescents: provide privacy, communicate directly with the patient (not just parents), discuss confidentiality.

The ACIP (Advisory Committee on Immunisation Practices) schedule is the standard tested on NCLEX-PN. Key concepts: birth (HepB), 2 months (DTaP, Hib, IPV, PCV, RV), 4 months (same), 6 months (+ influenza annually), 12–15 months (MMR, varicella, HepA), 4–6 years (DTaP, IPV, MMR, varicella booster).

True vs. false contraindications: True contraindications: previous severe allergic reaction to vaccine component (anaphylaxis), encephalopathy within 7 days of prior DTaP (contraindication to further pertussis-containing vaccines), live vaccines in severely immunocompromised patients. False contraindications (vaccine can be given): mild illness with low-grade fever, antibiotic therapy, convalescence from illness, family history of adverse reactions, breastfeeding.

Common parent misconceptions: Vaccines do not cause autism (scientific consensus is clear). Combination vaccines are safe and do not overload the immune system. A mild cold is not a reason to delay vaccination.
