The nurse meets the frantic father at an ED door. He says he just delivered his wife’s full-term newborn in the car when the temperature outside is only 10°F (—12.2°C). In response to the cold environment,the nurse knows that the infant’s body will immediately begin to produce heat by which mechanism?
- A. Shivering
- B. Metabolizing body fat
- C. Dilating surface blood vessels
- D. Decreasing flexion of the extremities
Correct Answer: B
Rationale: When skin receptors of full-term newborns perceive a drop in environmental temperature the sympathetic nervous system is stimulated. This in turn stimulates metabolism of brown fat thus producing heat that is transferred to the peripheral circulation. Shivering is rarely seen in newborns and it does little to produce heat. Newborns conserve heat by constricting not dilating blood vessels. Decreasing flexion promotes heat loss by exposing more skin surface.
