The nurse caring for an infant at risk for hypothermia knows that the function of brown adipose tissue (BAT) in a newborn is what?
Insulating the body against lowered environmental temperatures.
Protection for the infant from birth injuries.
Being available to be metabolized by body when heat is needed.
Providing a ready source of calories for the newborn.
The Correct Answer is C
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.
