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

The correct answer is c. Dehydration. A significantly indented anterior fontanelle in a newborn is most commonly a sign of dehydration.

Choice A reason:

Increased intracranial pressure: This statement is incorrect because increased intracranial pressure typically causes a bulging, not indented, fontanelle. Symptoms include irritability, vomiting, and a high-pitched cry.

Choice B reason:

Vernix caseosa: This statement is incorrect because vernix caseosa is a white, cheesy substance covering the skin of newborns, unrelated to fontanelle indentation. It serves as a protective layer for the baby’s skin.

Choice C reason:

Dehydration: This statement is correct. Dehydration in newborns can cause a sunken fontanelle due to the loss of fluid. Other signs include dry mouth, sunken eyes, and fewer wet diapers.

Choice D reason:

Cyanosis: This statement is incorrect because cyanosis refers to a bluish discoloration of the skin due to lack of oxygen, not related to fontanelle shape. It indicates issues with oxygenation or circulation.

A. Change her position to the right side. B. Place a wedge under the left hip. C. Lower the head of the bed. D. Place the mother in a Trendelenburg position.

Correct Answer is B

Explanation

Choice A: Change her position to the right side

Changing the mother’s position to the right side can sometimes help improve fetal oxygenation by relieving pressure on the vena cava. However, since the mother is already lying on her left side, which is typically the preferred position to optimize blood flow, changing to the right side may not be as effective .

Choice B: Place a wedge under the left hip

Placing a wedge under the left hip is a common intervention to improve uteroplacental blood flow. This position helps to tilt the uterus off the vena cava, enhancing venous return and improving cardiac output, which can positively affect fetal oxygenation. This is why it is the correct answer.

Choice C: Lower the head of the bed

Lowering the head of the bed can help increase blood flow to the upper body and brain, but it does not specifically address the issue of improving uteroplacental blood flow. This action is less targeted for resolving nonreassuring fetal heart rate patterns.

Choice D: Place the mother in a Trendelenburg position

The Trendelenburg position, where the mother is laid flat on her back with her feet elevated higher than her head, is generally used to treat hypotension or to improve venous return in cases of shock. However, it is not typically recommended for nonreassuring fetal heart rate patterns as it can increase pressure on the diaphragm and reduce respiratory efficiency.
