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

Choice A reason:

If the client reports frequent uterine contractions , it is not indicative of a distended bladder. Postpartum uterine contractions are normal and necessary to help the uterus return to its pre-pregnancy size.

Choice B reason:

The fundus (the top portion of the uterus being palpable to the right of the midline suggests a distended bladder. A full bladder can displace the uterus, causing the fundus to deviate from the midline.

Choice C reason:

Having less than 2.5 cm of rubra lochia on a perineal pad is related to the amount of vaginal discharge after birth and does not provide information about bladder distention.

Choice D reason:

The client's report of increased thirst may indicate dehydration or the body's response to fluid loss during childbirth but is not directly related to bladder distention.

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.
