Choose the sign or symptom that a new mother should be taught to report:

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:

This is the best response because it shows that the nurse is providing nonpharmacological pain relief measures and supporting the client's coping mechanisms. Breathing and imagery techniques can help the client relax and focus on something other than the pain. Moaning, screaming, and vocalizing are normal and acceptable ways of expressing pain during labor, and the nurse should not try to suppress them.

Choice B reason:

This is not the best response because it does not address the husband's concern or offer any intervention for the client's pain. Asking the client to rate her pain on a scale of 0 to 10 is a subjective assessment tool that may not reflect the true intensity of her pain. Furthermore, it may be difficult for the client to answer this question while she is in the second stage of labor.

Choice C reason:

This is not the best response because it may not be feasible or appropriate to administer more pain medication to the client in the second stage of labor. The obstetrician may not be available to evaluate the client's pain, and increasing the dose of pain medication may have adverse effects on the client and the fetus, such as respiratory depression, hypotension, and decreased uterine contractility.

Choice D reason:

This is not the best response because it does not acknowledge the husband's feelings or provide any comfort or education for him. Reassuring him that his wife will be fine may sound dismissive and insensitive, and offering to stay with her while he takes a walk may imply that he is not needed or wanted in the birthing room. The nurse should involve the husband in the care of his wife and explain to him what is happening and what to expect during labor.
