A nursing student is helping the nursery nurses with morning vital signs. A baby born 10 hours ago via cesarean section is found to have moist lung sounds. What is the best interpretation of these data?

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.

A. The woman had a vacuum-assisted birth. While vacuum-assisted births can cause perineal trauma, the specific orders for ice packs, sitz baths, and stool softeners are more directly related to an episiotomy, which involves a surgical incision that requires careful postpartum care.

B. The woman is a gravida 2, para 2. This information indicates the woman's obstetric history but does not directly correlate with the need for perineal ice packs, sitz baths, and stool softeners. These orders are more specific to perineal trauma or surgical intervention.

C. The woman has an episiotomy. An episiotomy involves a surgical cut made at the opening of the vagina during childbirth, which can cause significant perineal pain and swelling. The orders for perineal ice packs, sitz baths, and stool softeners are intended to manage pain, reduce swelling, and prevent constipation, which can be particularly uncomfortable with perineal stitches.

D. The woman received epidural anesthesia. While epidural anesthesia is a common pain management technique during labor, it does not necessitate the use of perineal ice packs, sitz baths, or stool softeners postpartum. These orders are more indicative of perineal trauma or surgical intervention such as an episiotomy.
