Which physiologic mechanism does the newborn use to maintain body temperature?

a. Shivering
b. Metabolism of brown fat
c. Production of fatty acids
d. Decreased glucose metabolism

Question 2

The assessment of a newborn at 1 hour of age reveals the following: temperature 36.0 C (96.7 F), heart rate 158 beats/minute, respiratory rate 55 breaths/minute, color pink with acrocyanosis.

Based on these clinical findings, the nurse should conclude that:
a. The infant is in respiratory distress.
b. Measures to warm the infant should be taken.
c. The infant is showing signs of cold stress.
d. No nursing interventions are necessary.

Answer to Question 1

ANS: B
The metabolism of brown fat helps the newborn maintain heat around vital organs. Newborns cannot shiver like adults. The production of fatty acids occurs, but it is not adaptive because it can cause metabolic acidosis. Glucose metabolism increases when the newborn is chilled.

Answer to Question 2

ANS: B
The temperature is low, and measures should be instituted to warm the infant to prevent cold stress. The heart and respiratory rates are within normal ranges.
