A nurse places a newborn under a radiant heat warmer after birth.
The purpose of this action is to prevent which of the following in the newborn?
Shivering.
Cold stress.
Brown fat production.
Basal metabolic rate reduction.
The Correct Answer is B
Choice A rationale
Shivering is not a primary concern for newborns as they have limited ability to shiver. Instead, they rely on non-shivering thermogenesis to maintain body temperature.
Choice B rationale
Cold stress is a significant concern for newborns as it can lead to hypothermia, increased oxygen consumption, and metabolic acidosis. Placing a newborn under a radiant heat warmer helps maintain their body temperature and prevent cold stress.
Choice C rationale
Brown fat production is a natural process in newborns that helps generate heat. However, the primary purpose of using a radiant heat warmer is to prevent cold stress, not to stimulate brown fat production.
Choice D rationale
Basal metabolic rate reduction is not the primary concern. The focus is on preventing cold stress and maintaining the newborn’s body temperature.

- “The glans penis will appear red and have a yellow crust as it heals. Do not remove this.”
- Essential: This is a normal part of the healing process.
- “Ensure the diaper is really tight to keep the gauze attached to the penis.”
- Contraindicated: The diaper should be loose to avoid pressure on the circumcision site.
- “Notify your pediatrician if your baby has not voided in 24 hours.”
- Essential: This could indicate a problem that needs medical attention.
- “Coat the glans penis with petroleum jelly and cover with gauze.”
- Essential: This helps prevent the diaper from sticking to the circumcision site and aids in healing.
- “Check for bleeding every 4 hours for the first 24 hours and notify your pediatrician if there is bleeding at the circumcision site.”
- Essential: Monitoring for bleeding is crucial to ensure there are no complications.
Correct Answer is A
Explanation
Choice A rationale
Drying the newborn’s skin thoroughly immediately after birth helps reduce heat loss by evaporation, which is a significant concern as wet skin can cause rapid heat loss.
Choice B rationale
Maintaining ambient room temperature at 24°C (75°F) helps prevent heat loss by convection but does not directly address evaporation.
Choice C rationale
Placing the newborn on a warm surface helps prevent heat loss by conduction but does not address evaporation.
Choice D rationale
Preventing air drafts helps reduce heat loss by convection but does not address evaporation.
