Health Promotion, Growth, and Development
Health promotion as a continuum
Pediatric health promotion is longitudinal, family-centered, and anticipatory rather than reactive. Candidates must know growth-chart interpretation (serial measurements, percentiles, and growth velocity), developmental surveillance and screening, age-specific anticipatory guidance, immunization principles, nutrition (breastfeeding, iron, vitamin D, obesity prevention), oral health, injury prevention, and screening schedules (vision, hearing, lead, anemia, autism). Recognize social determinants and the nurse's role in connecting families to resources.
Traps
A common trap is using chronological age instead of corrected age for a preterm infant. Another is treating a single low percentile as failure to thrive while ignoring a child who crosses two major percentile lines downward. A missed milestone is a prompt for surveillance and referral, not an automatic diagnosis; loss of previously acquired skills is a red flag. Vaccine questions often test true contraindications (severe allergic reaction to a vaccine component or prior dose; live vaccines in significant immunocompromise) versus mild illness, which is not a reason to delay. Do not apply adult BMI or vital-sign norms to children.
Worked example
An infant born at 30 weeks is 9 months chronological. Weeks preterm = 10. Corrected age = 9 months minus about 10 weeks, or roughly 7 months. Use corrected age for milestone expectations and growth until 24 months. Rule of thumb: corrected age = chronological age minus weeks born early.
