The student nurse learns that the hormone necessary for milk production is

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.

Choice A reason:

The nurse's priority in this situation is the client's blood pressure of 80/56 mm Hg. Opioid epidural analgesia can cause a drop in blood pressure, known as hypotension. Hypotension can be a significant concern during labor, as it may reduce blood flow to the placenta and compromise the baby's well-being. Therefore, it is crucial for the nurse to address this finding promptly to prevent any adverse effects on both the mother and the baby. The nurse may need to administer intravenous fluids, adjust the dosage of the opioid medication, or take other appropriate actions to raise the blood pressure to a safer level.

Choice B reason:

While profuse itching (choice B) can be a common side effect of opioids, it is not the nurse's priority in this situation. Itching, also known as pruritus, can be managed with antihistamines or other supportive measures, but it is not an immediate threat to the client's well-being.

Choice C reason:

The client reporting weakness of the lower extremities (choice C) is an expected side effect of epidural analgesia. Epidurals can cause temporary paralysis or weakness in the lower body due to the local anesthetic's effects on the nerves. While it's essential to monitor and support the client during this time, it is not the priority over the potentially dangerous drop in blood pressure.

Choice D reason:

A temperature of 38.2°C (100.8 F) (choice D) may indicate a fever, but it is not the nurse's priority in this specific situation of opioid epidural analgesia during labor. Fever during labor could have various causes, and the nurse should investigate and manage it appropriately. However, addressing the client's blood pressure takes precedence, as hypotension can have immediate and significant consequences.
