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.

Correct Answer is ["A","D","E","F"]
Explanation
Choice A rationale
Bottles can be put in the dishwasher, boiled, or cleaned with hot soapy water to ensure they are thoroughly sanitized and safe for the infant.
Choice B rationale
Holding the baby in a supine position during feedings is incorrect because it increases the risk of aspiration. The baby should be held in a semi-upright position.
Choice C rationale
Only burping the baby after they have finished the entire feeding is incorrect because it can lead to discomfort and gas buildup. The baby should be burped during and after feedings.
Choice D rationale
Always holding the bottle while feeding and not propping the bottle is correct as it prevents choking and ensures the baby is feeding safely.
Choice E rationale
Keeping the nipple full of formula throughout the feeding is correct as it prevents the baby from swallowing air, which can cause gas and discomfort.
Choice F rationale
Prepared formula can be kept in the refrigerator for 48 hours, ensuring it remains safe and free from bacterial growth.
