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 C
Explanation
Choice A rationale
Inserting an indwelling urinary catheter is not the immediate next step. While it may be necessary in some cases, the priority is to address the client’s excessive bleeding, which is a sign of postpartum hemorrhage.
Choice B rationale
Administering oxytocin by continuous IV infusion is a common intervention for postpartum hemorrhage. However, it is not the immediate next step. The nurse should first attempt to massage the client’s fundus to promote contractions and control bleeding.
Choice C rationale
Massaging the client’s fundus is the correct next step. The client’s symptoms indicate postpartum hemorrhage, a serious condition that can lead to shock and other complications. Fundal massage often helps the uterus contract and can stop the bleeding.
Choice D rationale
Tilting the client onto her right side with her legs elevated to at least 30 degrees is not the immediate next step. This position can help improve venous return but does not directly address the cause of the client’s symptoms.
Correct Answer is ["0.8"]
Explanation
Step 1 is to determine the amount of heparin to administer. The client is receiving 3,800 units of heparin, and the available heparin is 5,000 units/mL.
Step 2 is to set up the calculation: (3,800 units ÷ 5,000 units/mL) = x mL.
Step 3 is to perform the calculation: x = 0.76 mL. Therefore, the nurse should administer 0.8 mL of heparin, rounded to the nearest tenth.
