What is the purpose of placing a newborn under a radiant heat warmer after birth?
To prevent basal metabolic rate reduction.
To stimulate brown fat production.
To maintain body temperature.
To prevent hypothermia.
The Correct Answer is C
Choice A rationale
Placing a newborn under a radiant heat warmer after birth does not directly prevent basal metabolic rate reduction. The primary function of a radiant heat warmer is to maintain the newborn’s body temperature and prevent hypothermia.
Choice B rationale
While brown fat production is a mechanism used by newborns to generate heat, placing a newborn under a radiant heat warmer does not stimulate brown fat production.
Choice C rationale
The primary purpose of placing a newborn under a radiant heat warmer after birth is to maintain the newborn’s body temperature. Newborns can lose heat rapidly, as they have a
large surface area compared to their body weight. The radiant heat warmer provides a controlled environment that helps maintain the newborn’s body temperature.
Choice D rationale
Preventing hypothermia is a key reason for placing a newborn under a radiant heat warmer. However, the direct purpose of the warmer is to maintain the newborn’s body temperature.

Correct Answer is B
Explanation
Choice A rationale
Inserting an indwelling urinary catheter is not the priority nursing action. While it may be necessary later, especially if the client goes to surgery, it is not the immediate concern.
Choice B rationale
Initiating IV access is the correct action. The client is losing blood rapidly, has hypotension, and tachycardia. IV access will allow IV fluids and blood to be administered quickly if hypovolemia develops.
Choice C rationale
Witnessing the signature for informed consent for surgery is not the priority nursing action. While consent will be necessary if the client needs a cesarean section, the immediate concern is stabilizing the client.
Choice D rationale
Preparing the abdominal and perineal areas is not the priority nursing action. This would be done as part of surgical preparation if a cesarean section is needed, but it is not the immediate concern.
Correct Answer is B
Explanation
Choice A rationale
Betamethasone does not typically increase the fetal heart rate14.

Betamethasone is often given to pregnant women who are at risk of preterm birth to promote fetal lung maturity. It helps speed up the development of the baby’s lungs and other organs14.
Choice C rationale
Betamethasone is not used to stop preterm labor contractions14.
Choice D rationale
Betamethasone does not halt cervical dilation14.
