1. What is the primary mechanism by which phototherapy reduces serum bilirubin levels? → Converts unconjugated bilirubin to water-soluble photoisomers excreted without conjugation
2. A neonate has a serum glucose of 300 mg/dL on day 2 of TPN. What is the first step in management? → Reduce the dextrose concentration in TPN and recheck glucose
3. A premature infant in the NICU benefits most from which developmental care principle to reduce stress? → Clustering care activities and providing containment/nesting
4. A term neonate has a serum bilirubin of 22 mg/dL at 48 hours of life. Direct Coombs test is positive. Which condition is most likely? → ABO incompatibility
5. What is the mechanism of action of phenytoin in treating neonatal seizures? → Blocks voltage-gated sodium channels to stabilize neuronal membranes
6. Which finding on neonatal MRI is most predictive of adverse neurodevelopmental outcomes after HIE? → Basal ganglia and thalamic injury on diffusion-weighted imaging
7. A neonate presents with jitteriness and irritability at 24 hours of age. Mother has a history of opioid use disorder. What condition is most likely? → Neonatal opioid withdrawal syndrome (NOWS)
8. Which intervention has been shown to reduce the incidence and severity of IVH in premature neonates? → Antenatal corticosteroids administered to the mother
9. Which of the following is the greatest technique to swiftly remove air from the chest cavity in the case of a baby with pneumothorax symptoms? → Using a needle and syringe
10. What is the recommended caloric intake to support adequate growth in a stable premature neonate? → 110-130 kcal/kg/day
11. Which antibiotic combination is the standard empiric therapy for early-onset neonatal sepsis in the US? → Ampicillin and gentamicin
12. Which chromosomal abnormality is most commonly associated with duodenal atresia in the newborn? → Trisomy 21 (Down syndrome)
13. Which of the following maternal blood types places a neonate at highest risk for significant ABO hemolytic disease? → Type O mother with type A or B infant
14. Total parenteral nutrition (TPN) in neonates typically starts with which amino acid concentration to promote anabolism? → 3-4 g/kg/day starting on day 1
15. Which reversal agent is used for opioid-induced respiratory depression in a neonate? → Naloxone
16. A VLBW neonate has a serum sodium of 128 mEq/L on day 3 of life with urine output of 6 mL/kg/hr. What is the most likely cause? → Excessive free water administration (dilutional hyponatremia)
17. Why is erythromycin eye ointment applied to neonates at birth in the US? → Prophylaxis against Neisseria gonorrhoeae ophthalmia neonatorum
18. Which chest X-ray finding is classic for respiratory distress syndrome (RDS) in a premature neonate? → Diffuse ground-glass appearance with air bronchograms
19. What is the primary mechanism by which prostaglandin E1 (PGE1) helps a ductal-dependent lesion? → Maintains or reopens the ductus arteriosus
20. What is the blood glucose threshold below which treatment is recommended for a symptomatic neonate in the US per AAP guidelines? → 50 mg/dL
21. Dexamethasone given postnatally for BPD carries a significant risk of: → Neurodevelopmental impairment and GI perforation
22. What is the primary risk associated with chloramphenicol use in neonates? → Gray baby syndrome due to immature hepatic metabolism

26. Kangaroo care (skin-to-skin holding) in the NICU has been shown to provide which benefit? → Stabilize temperature, heart rate, and improve breastfeeding outcomes
27. High-frequency oscillatory ventilation (HFOV) is preferred in which neonatal condition? → Pulmonary interstitial emphysema (PIE)
28. A neonate of a diabetic mother is at increased risk for hypoglycemia primarily because of: → Fetal hyperinsulinism from chronic fetal hyperglycemia
29. What is the recommended initial FiO2 for resuscitation of a term neonate at birth in the US? → 21%
30. In the first 24 hours of life, what is the primary reason insensible water loss is high in extremely premature neonates? → Thin, poorly keratinized skin with large surface area-to-volume ratio
