Pediatrics High-Yield: Well-Child Visits, Vaccines, and Common Peds Conditions for FNP Boards
Clinical High-Yield · 12 min read · April 28, 2026
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 Milestones: The Ages That Matter
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.
Immunization Schedule: The High-Yield Vaccines
The boards test the immunization schedule directly — specific vaccines at specific ages, contraindications, and catch-up schedules. Know these cold.
Birth: Hepatitis B (HepB) #1.
2 months: DTaP #1, IPV #1, Hib #1, PCV15/20 #1, RV #1, HepB #2.
4 months: DTaP #2, IPV #2, Hib #2, PCV #2, RV #2.
6 months: DTaP #3, IPV #3 (can be given 6–18 months), Hib #3 (if needed), PCV #3, RV #3 (if needed), HepB #3, annual influenza (starting 6 months).
12–15 months: MMR #1, Varicella #1, Hib #4, PCV #4, HepA #1.
15–18 months: DTaP #4.
18–23 months: HepA #2 (6 months after #1).
4–6 years: DTaP #5, IPV #4, MMR #2, Varicella #2.
11–12 years: Tdap (booster), HPV series (2 doses if started before age 15), MenACWY #1.
16 years: MenACWY #2.
Key contraindications the boards test: MMR and Varicella are live vaccines — contraindicated in pregnancy and in immunocompromised patients (with some exceptions). Rotavirus is contraindicated in infants with a history of intussusception or severe combined immunodeficiency (SCID). Influenza live attenuated vaccine (LAIV, the nasal spray) is contraindicated in immunocompromised patients, pregnant women, and children with severe asthma.
Common Pediatric Conditions: The Board Favorites
Otitis Media (AOM): The most common reason for antibiotic prescriptions in children. Presentation: ear pain, fever, irritability, pulling at ear. Otoscopy shows a bulging, erythematous tympanic membrane with loss of landmarks and light reflex. First-line treatment: amoxicillin (90 mg/kg/day in 2 divided doses) for children ≥2 years with severe symptoms or bilateral AOM, or for children <2 years. For children ≥2 years with mild unilateral AOM, watchful waiting for 48–72 hours is appropriate. Amoxicillin-clavulanate for treatment failure.
Croup (Laryngotracheobronchitis): Caused by parainfluenza virus. Presents in children 6 months–3 years with a barking (seal-like) cough, stridor, and hoarse voice, typically worse at night. The steeple sign on AP neck X-ray (subglottic narrowing) is pathognomonic. Treatment: cool mist or humidified air (limited evidence but commonly used), a single dose of dexamethasone (0.6 mg/kg PO/IM) for moderate-to-severe croup, and nebulized racemic epinephrine for severe cases.
Epiglottitis: A medical emergency. Caused by H. influenzae type b (Hib) — now rare due to vaccination. Presentation: high fever, drooling, dysphagia, muffled voice ("hot potato voice"), and the tripod position (leaning forward with neck extended). Do not examine the throat — it can precipitate complete airway obstruction. Secure the airway first, then treat with IV antibiotics (ceftriaxone).
Bronchiolitis: The most common lower respiratory tract infection in infants, caused by RSV. Presents in children <2 years with rhinorrhea, cough, low-grade fever, wheezing, and respiratory distress. Treatment is supportive — supplemental oxygen if SpO2 <90%, adequate hydration. Bronchodilators and corticosteroids are NOT recommended (this is a high-yield board point).
Febrile Seizures: The most common seizure type in children aged 6 months–5 years. Simple febrile seizures are generalized, last <15 minutes, and do not recur within 24 hours. Complex febrile seizures are focal, last >15 minutes, or recur within 24 hours. Simple febrile seizures do not require EEG, neuroimaging, or lumbar puncture (unless meningitis is suspected). They do not increase the risk of epilepsy significantly and do not require prophylactic AED therapy.
Lead Screening and Anticipatory Guidance
Lead screening: Universal blood lead level (BLL) screening at 12 and 24 months for children in high-risk areas (pre-1978 housing, Medicaid enrollment). Elevated BLL ≥3.5 mcg/dL requires follow-up and environmental investigation. Chelation therapy is indicated for BLL ≥45 mcg/dL.
Anticipatory guidance by age: The boards test that anticipatory guidance is a core component of every well-child visit. Key topics by age: safe sleep (supine position, firm mattress, no soft bedding) for infants; car seat safety (rear-facing until age 2, forward-facing until 4–8 years, booster until 8–12 years); screen time (none before 18–24 months except video chat, 1 hour/day of high-quality programming for 2–5 years); dental care (first dental visit by age 1, fluoride varnish starting at eruption of first tooth).
The Bottom Line
Pediatrics on the FNP boards rewards knowing the developmental milestones by age, the immunization schedule with its contraindications, and the handful of childhood conditions that have board-specific management pearls. Know your milestone red flags. Know your vaccine contraindications. Know that bronchiolitis is supportive care only. Know that simple febrile seizures do not require workup. Master these and you will handle the pediatrics section with confidence.
