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?

A.

Preterm newborns lack the ability to regulate their own temperatures.

B.

The heat in the incubator rapidly dries the sweat of preterm newborns.

C.

Preterm newborns have a smaller body surface area than normal newborns.

D.

The added brown fat layer in a preterm newborn reduces his ability to generate heat.

Answer and Explanation

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 D

Explanation

Choice A rationale

Administering vitamin K is important but not the immediate priority right after birth.

Choice B rationale

Administering eye prophylaxis is also necessary but comes after ensuring the newborn is dry to prevent heat loss.

Choice C rationale

Placing an identification bracelet is crucial but not as immediate as drying the skin to regulate the baby's temperature.

Choice D rationale

Drying the skin is the priority to prevent hypothermia by reducing evaporative heat loss right after birth

Correct Answer is ["A","B","C","E"]

Explanation

Choice A rationale

Serving food in small, halved, or quartered pieces can help prevent choking, which is a significant concern for infants and young children who are still developing their chewing and swallowing skills.

Choice B rationale

Ensuring the mattress fits snugly against the sides of the crib prevents the infant from getting trapped between the mattress and the crib sides, reducing the risk of suffocation or injury.

Choice C rationale

Child-proof locks on cabinet doors prevent infants from accessing hazardous substances or dangerous objects that could cause harm. This is a crucial aspect of home safety for young children.

Choice D rationale

Setting the water heater at 65°C (149°F) is not recommended because it is too hot and can cause burns. The water heater should be set at a maximum of 48°C (118°F) to prevent scalding injuries.

Choice E rationale

Never leaving a child unattended during bath time is essential to prevent drowning, which can occur quickly and silently. Close supervision is necessary to ensure the child’s safety in the water. .
