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 D
Explanation
Choice A rationale
While it is important to monitor a client’s temperature regularly, especially if they have a fever, simply checking the client’s temperature in 4 hours is not an adequate response to a temperature of 38.9°C (102°F) in a woman who is at 38 weeks of gestation and in early labor with ruptured membranes. This could indicate an infection, which could be dangerous for both the mother and the baby.
Choice B rationale
Administering glucocorticoids intramuscularly is not typically the first-line treatment for a fever in a pregnant woman. Glucocorticoids are often used to accelerate fetal lung maturity in preterm labor, but they are not typically used to treat infections or fevers.
Choice C rationale
Preparing the client for an emergency cesarean section may be necessary if the client’s condition worsens or if there are other complications, but it is not the immediate response to a fever. The first step would be to identify and treat the cause of the fever, which could be an infection.
Choice D rationale
Administering acetaminophen orally is an appropriate nursing action for a client with a fever. Acetaminophen can help to reduce the client’s fever and make her more comfortable. However, it is also important to identify and treat the underlying cause of the fever, which could be an infection.
Correct Answer is B
Explanation
Choice A rationale
Administering oxytocin infusion is usually done to stimulate uterine contractions and prevent postpartum hemorrhage. However, it’s not the first action to take when the client’s blood pressure is low.
Choice B rationale
Evaluating the firmness of the uterus is crucial in this situation. A soft or “boggy” uterus could indicate uterine atony, a condition that can lead to serious postpartum hemorrhage. This could be the cause of the client’s low blood pressure.
Choice C rationale
Initiating oxygen therapy by non-rebreather mask can help increase the client’s oxygen saturation levels, but it doesn’t address the underlying cause of the low blood pressure.
Choice D rationale
Obtaining a type and crossmatch is important if the client needs a blood transfusion. However, it’s not the first action to take. The nurse should first assess for possible causes of the low blood pressure.
