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 C
Explanation
Choice A rationale
Monitoring blood glucose levels frequently is important for newborns, especially those at risk for hypoglycemia. However, it does not directly prevent jaundice. Jaundice is caused by elevated bilirubin levels, which are not directly related to blood glucose levels.
Choice B rationale
Beginning phototherapy immediately is a treatment for jaundice, not a preventive measure. Phototherapy is used to reduce high bilirubin levels in newborns who already have jaundice.
Choice C rationale
Initiating early feeding is an effective way to prevent jaundice in newborns. Early feeding helps promote regular bowel movements, which aids in the excretion of bilirubin from the body, thereby reducing the risk of jaundice.
Choice D rationale
Preparing for a blood transfusion is a treatment for severe jaundice, not a preventive measure. Blood transfusions are used in cases of extreme hyperbilirubinemia that do not respond to other treatments.
Correct Answer is ["A","B","C","E"]
Explanation
Choice A rationale
Sucking on their fingers is an early hunger cue in infants. It indicates that the baby is ready to feed.
Choice B rationale
Smacking their lips is another early hunger cue. It shows that the baby is thinking about feeding.
Choice C rationale
Extending their tongue is also an early hunger cue. It indicates that the baby is ready to latch onto the breast or bottle.
Choice D rationale
Crying is a late hunger cue. It is better to feed the baby before they start crying to make feeding easier.
Choice E rationale
Rooting is an early hunger cue. It involves the baby turning their head towards the breast or bottle, indicating they are ready to feed. .
