Pediatrics: Growth, Development, and Integrated Care
Pediatrics rewards a developmental and preventive mindset. Know the immunization schedule milestones, growth chart interpretation (weight-for-age, length-for-age, weight-for-length), and developmental red flags at each visit. Distinguish failure to thrive from constitutional small stature by crossing percentile lines on the growth curve rather than a single measurement. In neonates, recognize the danger signs: poor feeding, lethargy, hypothermia, and respiratory distress demand prompt evaluation for sepsis.
High-yield clinical patterns
Bronchiolitis in infants under two years is viral (respiratory syncytial virus) and managed supportively - oxygen and hydration, not routine antibiotics or bronchodilators. Croup presents with a barking cough and inspiratory stridor and responds to corticosteroids. Acute otitis media requires bulging tympanic membrane, not just redness. Dehydration is assessed clinically by capillary refill, skin turgor, and mental status; oral rehydration is first line for mild-moderate dehydration.
Traps
Questions often test the most appropriate next step in a well-appearing versus toxic child. A toxic-appearing infant with fever gets a full sepsis workup regardless of source. Watch for age cutoffs that change management, such as the febrile infant under 28 days.
Rule of thumb
Use the pediatric assessment triangle - appearance, work of breathing, circulation - to triage severity before detailed history. If the child looks well but the parent is worried, still document and reassess.
