A nurse places a newborn under a radiant heat warmer after birth. The purpose of this action is to prevent which of the following in the newborn?

A.

Shivering.

B.

Cold stress.

C.

Brown fat production.

D.

Basal metabolic rate reduction.

Answer and Explanation

The Correct Answer is B

Choice A rationale

 

Shivering is not a primary concern for newborns as they have limited ability to shiver. Instead, they rely on non-shivering thermogenesis to maintain body temperature.

 

Choice B rationale

 

Cold stress is a significant concern for newborns as it can lead to hypothermia, increased oxygen consumption, and metabolic acidosis. Placing a newborn under a radiant heat warmer helps maintain their body temperature and prevent cold stress.

 

Choice C rationale

 

Brown fat production is a natural process in newborns that helps generate heat. However, the primary purpose of using a radiant heat warmer is to prevent cold stress, not to stimulate brown fat production.

 

Choice D rationale

 

Basal metabolic rate reduction is not the primary concern. The focus is on preventing cold stress and maintaining the newborn’s body temperature.

Correct Answer is A

Explanation

Choice A rationale

Placing a baby on their back to sleep significantly reduces the risk of SIDS. This position helps keep the airway open and reduces the risk of suffocation.

Choice B rationale

There is no direct correlation between SIDS and the diphtheria, tetanus, and pertussis vaccines. Vaccines are safe and do not increase the risk of SIDS3.

Choice C rationale

SIDS rates have actually decreased over the last 10 years, largely due to public health campaigns promoting safe sleep practices.

Choice D rationale

Sleep apnea is not the main cause of SIDS. The exact cause of SIDS is unknown, but it is believed to be related to defects in the brain that control breathing and arousal from sleep.

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

Explanation

Choice A rationale

Sucking on their fingers is an early hunger cue in infants. It indicates that the baby is ready to feed.

Choice B rationale

Smacking their lips is another early hunger cue. It shows that the baby is thinking about feeding.

Choice C rationale

Extending their tongue is also an early hunger cue. It indicates that the baby is ready to latch onto the breast or bottle.

Choice D rationale

Crying is a late hunger cue. It is better to feed the baby before they start crying to make feeding easier.

Choice E rationale

Rooting is an early hunger cue. It involves the baby turning their head towards the breast or bottle, indicating they are ready to feed. .
