Why is cold stress dangerous for a newborn?
Answer: It increases oxygen and glucose use, causing hypoxia and hypoglycemia
Brown fat metabolism raises oxygen and glucose demand, risking hypoglycemia and acidosis.
Which combination is most characteristic of necrotizing enterocolitis?
Answer: Abdominal distension, bloody stools, and feeding intolerance
NEC presents with distension, bloody stools, bilious residuals, and may show pneumatosis intestinalis on X-ray.
What are the standard criteria for therapeutic hypothermia in hypoxic-ischemic encephalopathy?
Answer: Cooling to 33.5°C for 72 hours, started within 6 hours of birth
Whole-body cooling to 33–34°C for 72 hours should begin within 6 hours in eligible infants.
During resuscitation, how often can epinephrine be repeated if HR stays below 60 bpm?
Answer: Every 3–5 minutes
Epinephrine may be repeated every 3–5 minutes during compressions.
What volume expander dose is recommended for a hypovolemic newborn?
Answer: 10 mL/kg isotonic crystalloid or O-negative blood

A newborn is cyanotic at rest but pink when crying. Which condition is suspected?
Answer: Bilateral choanal atresia
Neonates are obligate nasal breathers; crying opens the oral airway and relieves cyanosis in choanal atresia.
A newborn with suspected congenital diaphragmatic hernia has respiratory distress and a scaphoid abdomen. What should be avoided?
Answer: Prolonged bag-mask ventilation
Bag-mask ventilation inflates the bowel in the chest; intubate early and decompress the stomach.
