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?

Basal metabolic rate reduction.

Brown fat production.

Shivering.

Cold stress.

Answer and Explanation

The Correct Answer is D

Choice A reason:

Basal metabolic rate reduction. This is incorrect because a newborn under a radiant heat warmer will have an increased basal metabolic rate, not a reduced one. The basal metabolic rate is the amount of energy the body uses at rest, and it is influenced by temperature. A warmer environment will stimulate the newborn's metabolism and increase the energy expenditure. • Choice B reason:

Brown fat production. This is incorrect because a newborn under a radiant heat warmer will have less need for brown fat production, not more. Brown fat is a type of fat tissue that generates heat by burning calories. It is found in newborns and helps them maintain their body temperature in cold environments. A warmer environment will reduce the need for brown fat activation. • Choice C reason:

Shivering. This is incorrect because a newborn under a radiant heat warmer will not shiver, but shivering is not the main mechanism of heat production in newborns. Shivering is an involuntary contraction of muscles that generates heat by increasing metabolism. Newborns have limited ability to shiver because of their immature nervous system and low muscle mass. They rely more on brown fat and increased metabolic rate to produce heat. • Choice D reason:

Cold stress. This is correct because a newborn under a radiant heat warmer will prevent cold stress, which is a condition where the newborn's body temperature drops below normal and causes adverse effects. Cold stress can impair oxygen delivery, increase acidosis, decrease blood glucose, and increase the risk of infection and bleeding. A radiant heat warmer provides a neutral thermal environment for the newborn and prevents heat loss by radiation.

Correct Answer is C

Explanation

Choice A reason:

While positioning is important for comfort during labor, addressing the immediate urge to push takes priority. Panting during contractions is the appropriate action.

Choice B reason:

Although observing for crowning is important when the client is close to delivery, the nurse should first intervene to address the client's urge to push since the client is only 7 cm dilated.

Choice C reason:

When a laboring client feels the urge to push but is not yet fully dilated (10 cm), encouraging her to pant can help reduce the urge to push and avoid complications, such as cervical swelling or tearing. This breathing technique helps the client delay pushing until full dilation and readiness of the cervix.
Choice D reason:

Assisting the client to the bathroom would not be appropriate at this stage of labor because the urge to push could lead to unsafe delivery outside the appropriate setting, and movement could increase discomfort or risks.

A. the interval between contractions. B. whenever she feels the need. C. second-stage of labor. D. first-stage of labor.

Correct Answer is C

Explanation

Choice A: the interval between contractions

Encouraging a laboring woman to push during the interval between contractions is not appropriate. During this time, the uterus is not contracting, and pushing would be ineffective and exhausting for the woman. The intervals are meant for rest and recovery to prepare for the next contraction.

Choice B: whenever she feels the need

While it is important to listen to the laboring woman’s instincts, pushing should be coordinated with contractions for maximum effectiveness. Pushing whenever she feels the need might not align with the contractions, leading to ineffective efforts and increased fatigue.

Choice C: second-stage of labor

The second stage of labor is the most appropriate time for the nurse to encourage a laboring woman to push. This stage begins when the cervix is fully dilated to 10 centimeters and ends with the birth of the baby. During this stage, contractions are strong and frequent, providing the necessary force to help push the baby through the birth canal.

Choice D: first-stage of labor

The first stage of labor involves the dilation and effacement of the cervix and is not the appropriate time for pushing. Pushing during this stage can cause unnecessary strain and may lead to complications. The focus during the first stage should be on managing contractions and conserving energy for the second stage.
