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 A
Explanation
Choice A rationale
Toddlers are at a stage where they are increasingly curious and mobile, which requires close supervision to ensure their safety. They are also prone to tantrums as they test
boundaries and express frustration due to limited communication skills. Effective management of tantrums and supervision can help parents guide their child's behavior and ensure
their safety.
Choice B rationale
Solitary play and identity development are more characteristic of older children. Toddlers engage more in parallel play, where they play alongside other children but not directly with
them. Encouraging solitary play is not as developmentally appropriate for toddlers.
Choice C rationale
Establishing trust is crucial in infancy when infants learn to trust their caregivers to meet their needs. Dental care should start around the toddler years, but the primary focus should
be on supervision and behavior management rather than dental care initiation.
Choice D rationale
Establishing relationships and developing self-confidence are vital across all developmental stages, but in toddlers, the priority lies in providing a safe environment and guiding
behavior through supervision and tantrum management.
