A nurse is caring for a newborn shortly after birth and places the newborn under a radiant warmer. Which of the following potential complications does this action help to prevent?
Cold stress
Thermogenesis
Shivering
Brown fat production
The Correct Answer is A
This action helps to prevent cold stress. This is because cold stress is a condition where the newborn's core temperature drops below 36.5°C and they use energy and oxygen to generate warmth. This can lead to hypoglycemia, metabolic acidosis, hypoxia, and an increased risk of infection.
Placing the newborn under a radiant warmer provides thermal stability and prevents heat loss by radiation.
Choice B is wrong because thermogenesis is the process of heat production, not a complication.
Choice C is wrong because shivering is a mechanism of heat production in adults, not in newborns.
Choice D is wrong because brown fat production is a normal feature of newborns that helps them generate heat by lipolysis.

Correct Answer is C
Explanation
Place the infant on the mother's abdomen after birth. This will help the infant maintain an adequate body temperature by providing skin-to-skin contact with the mother, which reduces heat loss and promotes bonding. Skin-to-skin contact also stimulates the baby's natural feeding cues and helps initiate breastfeeding.
Choice A is not correct because turning up the temperature in the birth room may not be enough to prevent heat loss from the infant, especially if they are wet or exposed to cold surfaces. It may also make the mother uncomfortable or dehydrated.
Choice B is not correct because bathing the infant immediately after birth may increase heat loss from evaporation and conduction. It may also interfere with the baby's natural protective coating (vernix) and microbiome. Bathing should be delayed until at least 24 hours after birth.
Choice D is not correct because wrapping the infant in a warm, dry blanket may not provide the same benefits as skin-to-skin contact with the mother. It may also prevent the baby from smelling and seeing the mother's breast, which are important cues for breastfeeding initiation.
Correct Answer is D
Explanation
Check for blood under the client's buttock. This is because lochia rubra is the normal vaginal discharge that occurs after childbirth, consisting of blood, mucus, and tissue from the placenta and the uterus lining. It is usually heavy for the first three to four days and can pool under the client's buttocks if they are lying down. Checking for blood under the buttock can help assess the amount of bleeding and prevent complications such as infection or hemorrhage.
The other choices are not correct for the following reasons:
A. Increasing the rate of the IV fluids is not necessary because the client's fundus is firm and midline, indicating that the uterus is contracting well and preventing excessive bleeding.
B. Assisting the client to ambulate is not advisable because it can increase the lochia flow and cause fainting or dizziness due to blood loss.
C. Performing fundal massage is not indicated because the fundus is already firm and midline, meaning that the uterus is adequately contracted. Massaging a firm fundus can cause pain and discomfort to the client.
