A newly admitted newborn has a temperature of 38.5°C (101.3°F) rectally. Which assessment is the most important first step?
Answer: Assess environmental temperature and whether the infant is overdressed or under a warmer set too high
Environmental hyperthermia from overheating is the most common cause of elevated temperature in newborns and must be ruled out before assuming infection.
What is the purpose of applying a stockinette cap to a newborn immediately after birth?
Answer: To reduce radiant and convective heat loss from the large head surface area
The head represents a large proportion of the newborn's body surface area, and a cap reduces significant heat loss by radiation and convection.
Which finding indicates that rewarming of a hypothermic newborn is proceeding safely?
Answer: Temperature rises by 0.5–1°C per hour with improving skin color and glucose stability
Safe rewarming targets a gradual temperature rise of 0.5–1°C per hour to prevent rewarming-associated apnea, hypotension, and metabolic instability.
A nurse swaddles a newborn for discharge education. Which teaching point about swaddling is most important for safety?
Answer: Always place a swaddled infant on the back to sleep to reduce SIDS risk
Swaddled infants must always be placed supine (back to sleep) because swaddling increases SIDS risk if the infant is placed prone.
Which assessment parameter is monitored most closely when a newborn is under phototherapy for hyperbilirubinemia?
Answer: Temperature, hydration status, and bilirubin levels
Phototherapy increases insensible water loss and generates heat, requiring close monitoring of temperature, fluid intake/output, and bilirubin trends.
A nurse is educating parents on the home environment for their newborn. Which room temperature range is recommended?
Answer: 68–72°F (20–22°C)
A room temperature of 68–72°F (20–22°C) is comfortable for a clothed or lightly swaddled term newborn and aligns with safe sleep recommendations.
