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
Fever. This is because fever is a sign of infection, which is a common and potentially serious postpartum complication. Infection can affect various parts of the body, such as the uterus (endometritis), the bladder (cystitis), the breast (mastitis), the wound (wound infection), or the blood (sepsis). Infection can cause symptoms such as fever, chills, pain, foul-smelling discharge, redness, swelling, or warmth at the site of infection.
Choice A is not correct because the change in lochia from red to white is not a sign of postpartum complication. Lochia is the vaginal discharge that occurs after childbirth. It changes color and amount over time, from red to pink to brown to yellow to white. This is a normal process of healing and does not indicate a problem unless the lochia is foul-smelling, heavy, or contains large clots³.
Choice B is not correct because fatigue and irritability are not signs of postpartum complications. Fatigue and irritability are common feelings after childbirth due to hormonal changes, sleep deprivation, physical recovery, and emotional adjustment. They do not necessarily indicate a problem unless they are severe or persistent and interfere with daily functioning or bonding with the baby.
Choice D is not correct because contractions are not signs of postpartum complication. Contractions are normal after childbirth and help the uterus shrink back to its pre-pregnancy size. They are usually mild and subside within a few days. They may be more intense during breastfeeding due to the release of oxytocin, which stimulates uterine contractions.
Correct Answer is A
Explanation
Clear the respiratory tract. This is because clearing the respiratory tract is the first step in the initial care of a newborn following vaginal delivery. The respiratory tract includes the nose, mouth, and lungs.
Clearing the respiratory tract helps the baby breathe more easily and prevents aspiration of amniotic fluid, blood, or mucus. The nurse can use a bulb syringe or a suction device to gently remove any fluid from the baby's nose and mouth.
Choice B is not correct because drying the infant off and covering the head is not the first action to take. Drying and covering the infant helps prevent heat loss and hypothermia, which are important for newborn care. However, this should be done after clearing the respiratory tract.
Choice C is not correct because stimulating the infant to cry is not the first action to take. Stimulating the infant to cry can help expand the lungs and improve oxygenation, which is also important for newborn care. However, this should be done after clearing the respiratory tract.
Choice D is not correct because clamping the umbilical cord is not the first action to take. Clamping and cutting the umbilical cord separates the baby from the placenta, which is no longer needed after birth. However, this should be done after clearing the respiratory tract.
