Pediatrics is a section that many FNP students underestimate — and then lose points on. The boards test a specific, predictable set of pediatric content: developmental milestones, immunization schedules, well-child visit components, and the handful of childhood conditions that present differently than their adult counterparts. Here's what you need to know.
Developmental milestone questions are almost always structured the same way: a child is described at a specific age, and you are asked whether their development is normal or whether a referral is warranted. The key is knowing the expected milestones at the ages the boards test most frequently.
2 months: Social smile (the most important milestone at this age), tracks objects past midline, vocalizes (cooing), lifts head briefly when prone.
4 months: Laughs, rolls front to back, brings hands to midline, reaches for objects, holds head steady.
6 months: Sits with support, transfers objects hand to hand, babbles (consonant sounds like "ba," "da"), recognizes faces.
9 months: Sits without support, pulls to stand, pincer grasp developing, says "mama/dada" nonspecifically, stranger anxiety begins.
12 months: Walks with support (cruising), says 1–2 words with meaning, waves bye-bye, pincer grasp mature, separation anxiety peaks.
18 months: Walks independently, says 10–20 words, points to body parts, uses a spoon, stacks 2–4 blocks.
24 months (2 years): Runs, climbs, 50+ words, 2-word phrases ("more milk"), follows 2-step commands, parallel play.
3 years: Rides tricycle, 3-word sentences, knows first and last name, dresses with help, interactive play begins.
4 years: Hops on one foot, 4–5 word sentences, draws a person with 4 parts, counts to 10.
5 years: Skips, ties shoes (some), 5+ word sentences, reads simple words, cooperative play.
Board Pearl: The most commonly tested "red flag" milestones: 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. Any of these warrants immediate developmental evaluation.
The boards test the immunization schedule directly — specific vaccines at specific ages, contraindications, and catch-up schedules. Know these cold.
