1. What is the primary stimulus for the first breath at birth?
A. Hypoxia
B. Hypercapnia
C. Cold exposure
D. All of the above
Answer: D – All of the above
Rationale: The first breath is triggered by a combination of
hypoxia (from cord clamping), hypercapnia (↑PaCO₂), acidosis,
cold exposure, and sensory input (touch, sound).

,2. What is the normal oxygen saturation target in the first 10
minutes of life for a term newborn?
A. 90–100%
B. 80–90%
C. 70–80%
D. 60–70%
Answer: D – 60–70%
Rationale: Per NRP guidelines, SpO₂ rises gradually: 1 min 60–
65%, 2 min 65–70%, 3 min 70–75%, 5 min 80–85%, 10 min
85–95%. Avoid 100% O₂.
3. What closes functionally within minutes after birth and
anatomically within months?
A. Ductus arteriosus
B. Foramen ovale
C. Ductus venosus
D. All of the above
2
,Answer: D – All of the above
Rationale: The foramen ovale closes functionally with increased left
atrial pressure; ductus arteriosus constricts due to ↑PaO₂; ductus
venosus closes with umbilical cord clamping.
4. Which fetal lung fluid clearance mechanism is most
important?
A. Pulmonary lymphatics
B. Epithelial sodium channels (ENaC)
C. Vaginal squeeze
D. Thoracic compression
Answer: B – Epithelial sodium channels (ENaC)
Rationale: ENaC upregulation near term actively reabsorbs lung
fluid. C-section infants without labor have delayed clearance.
5. A newborn has grunting, nasal flaring, and retractions. This
indicates:
A. CNS depression
3
, B. Respiratory distress
C. Normal transition
D. Cardiac failure
Answer: B – Respiratory distress
Rationale: Grunting generates PEEP to maintain FRC; retractions
indicate increased work of breathing. These are signs of respiratory
distress, not normal transition.
6. The normal heart rate (HR) in a term newborn immediately
after birth is:
A. 80–100 bpm
B. 100–120 bpm
C. 120–160 bpm
D. 160–200 bpm
Answer: C – 120–160 bpm
Rationale: Normal newborn HR ranges 120–160 bpm. HR <100
bpm indicates bradycardia requiring intervention per NRP.
