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 B
Explanation
Choice A rationale
Erythema toxicum is a common, benign rash seen in newborns. It appears as red patches with small white or yellow pustules in the center. It is not characterized by small raised pearly white spots on the nose and chin.
Choice B rationale
Milia spots are small raised pearly white spots that commonly appear on the nose, chin, and cheeks of newborns. They are caused by trapped keratin and are harmless, usually resolving on their own within a few weeks.
Choice C rationale
Mongolian spots are flat, blue-gray patches commonly found on the lower back and buttocks of newborns, especially those with darker skin. They are not raised and do not appear on the nose and chin.
Choice D rationale
Epstein’s pearls are small white or yellow cysts found on the gums or roof of the mouth in newborns. They are not found on the nose and chin. .
Correct Answer is D
Explanation
Choice A rationale
The xiphoid process is not the correct anatomical landmark for measuring chest circumference in newborns. It is located at the lower end of the sternum and does not provide a consistent measurement point.
Choice B rationale
The fifth intercostal space is not used for measuring chest circumference in newborns. This space is located between the ribs and is not a reliable landmark for consistent measurements.
Choice C rationale
The sternal notch is not the correct landmark for measuring chest circumference. It is located at the top of the sternum and does not provide a consistent measurement point.
Choice D rationale
The nipple line is the correct anatomical landmark for measuring chest circumference in newborns. This method ensures that the measurement is taken at a consistent and reproducible location, providing an accurate assessment of the chest size relative to growth and development standards.
