When assessing a newborn 1 hour after birth, the nurse measures an axillary temperature of 95.8° F (35.4° C), an apical pulse of 114 beats per minute, and a respiratory rate of 60 breaths per minute. The nurse would identify which area as the priority?

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:

Inspecting if the urethral opening appears circular. This is a correct action for the nurse to do, as it helps to identify any abnormalities in the urethral opening, such as hypospadias or epispadias, which are congenital defects where the opening is located on the underside or the top of the penis, respectively. • Choice B reason:

Retracting the foreskin over the glans to assess for secretions. This is an incorrect action for the nurse to avoid, as it can cause pain, bleeding, and infection in the newborn. The foreskin is usually adhered to the glans in newborns and should not be forcibly retracted. It will gradually loosen over time and can be retracted by the child himself when he is older. •

Choice C reason:

Palpating if testes are descended into the scrotal sac. This is a correct action for the nurse to do, as it helps to detect any undescended testes, which are more common in preterm infants and can increase the risk of infertility and testicular cancer later in life. • Choice D reason:

Inspecting the genital area for irritated skin. This is a correct action for the nurse to do, as it helps to identify any signs of diaper rash, fungal infection, or allergic reaction in the newborn's skin.
