Correct Answer is B

Explanation

A. The basal metabolic rate may increase as a result of cold stress, but the primary purpose of the warmer is to prevent cold stress.
B. Newborns are at risk of cold stress because they have a large body surface area and limited ability to regulate body temperature. A radiant warmer is used to help maintain the newborn’s body temperature and prevent cold stress.
C. Newborns do not typically shiver to generate heat. They rely on mechanisms such as non-shivering thermogenesis (use of brown fat).
D. Brown fat is used for heat production, but the goal of the radiant warmer is to prevent cold stress, not directly stimulate brown fat production.

A. Insulating the body against lowered environmental temperatures. B. Protection for the infant from birth injuries. C. Being available to be metabolized by body when heat is needed. D. Providing a ready source of calories for the newborn.

Correct Answer is C

Explanation

A. BAT does not primarily act as insulation but as a heat source.

B. BAT is unrelated to protection from birth injuries.

C. Brown adipose tissue (BAT) is metabolized to generate heat through non-shivering thermogenesis, which is critical for newborns as they cannot shiver effectively.

D. While BAT does provide some energy, its main purpose is heat production, not calorie storage.
