A nurse is caring for a preterm newborn who is in an incubator to maintain a neutral thermal environment.
The father of the newborn asks the nurse why this is necessary. Which of the following responses should the nurse make?
Preterm newborns lack the ability to regulate their own temperatures.
The heat in the incubator rapidly dries the sweat of preterm newborns.
Preterm newborns have a smaller body surface area than normal newborns.
The added brown fat layer in a preterm newborn reduces his ability to generate heat.
The Correct Answer is A
Choice A rationale
Preterm newborns have underdeveloped mechanisms for thermoregulation, making it difficult for them to maintain stable body temperatures without external assistance.
Choice B rationale
Preterm newborns do not sweat significantly because their sweat glands are not fully developed; thus, this rationale is incorrect.
Choice C rationale
Preterm newborns actually have a larger body surface area relative to their weight, contributing to their difficulty in maintaining body temperature.
Choice D rationale
Preterm newborns have insufficient brown fat, not an excess, which impairs their ability to generate heat effectively.

Correct Answer is C
Explanation
Choice A rationale
AAP guidelines recommend rear-facing car seats for children under 24 months due to superior protection in a collision.
Choice B rationale
The chest buckle should be at armpit level to prevent injury in case of a crash.
Choice C rationale
Switching to a forward-facing car seat at 12 months contradicts safety recommendations; the child should remain rear-facing until at least 2 years old.
Choice D rationale
Car seats should always be placed in the back seat to minimize risk from front airbags during collisions.
Correct Answer is A
Explanation
Choice A rationale
Monitoring for hypoglycemia is critical in newborns born to mothers with gestational diabetes, as they can experience significant drops in blood sugar levels post-birth due to the
sudden discontinuation of the high glucose supply from the mother.
Choice B rationale
Physiological jaundice is common in many newborns but does not represent the most immediate threat. It typically resolves within a few days with appropriate monitoring and care.
Choice C rationale
Hyperthermia can be a concern for newborns, but it is not the primary immediate complication in newborns born to gestational diabetic mothers. Hypoglycemia poses a greater
immediate risk.
Choice D rationale
Development of rash is generally a less critical concern and does not represent an immediate threat to the newborn’s well-being in comparison to hypoglycemia.
