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
Wiping the cord daily with alcohol prep pads is not recommended. Current guidelines suggest keeping the cord clean and dry without the use of alcohol, as it can delay the natural drying and falling off process.
Choice B rationale
Keeping the cord moist is not recommended. The cord should be kept dry to promote natural drying and separation. Moisture can increase the risk of infection.
Choice C rationale
Folding the top of the diaper underneath the cord is recommended to keep the cord exposed to air and prevent irritation from urine or stool. This helps the cord dry out and fall off naturally.
Choice D rationale
Applying petroleum jelly to the cord stump is not recommended. The cord should be kept dry, and the use of ointments or creams can interfere with the natural drying process. .
Correct Answer is B
Explanation
Choice A rationale
A newborn with a temperature of 37.0°C (98.6°F) is within the normal range for newborns and does not require immediate intervention.
Choice B rationale
A newborn who has not voided within 27 hours post-delivery requires immediate intervention. Newborns should void within the first 24 hours of life. Failure to void may indicate dehydration, urinary tract obstruction, or renal issues.
Choice C rationale
A newborn who has not passed meconium within 18 hours post-delivery is concerning but not as urgent as not voiding. Newborns typically pass meconium within the first 24-48 hours.
Choice D rationale
Acrocyanosis, or bluish discoloration of the hands and feet, is common in newborns and usually resolves on its own. It does not require immediate intervention.
