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

Answer and Explanation

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.

Here is an image of a newborn under a radiant warmer.

Correct Answer is C

Explanation

Administer low concentrations of oxygen. Retinopathy of prematurity (ROP) is a disease of retinal vascular and capillary proliferation affecting premature infants undergoing oxygen therapy. Oxygen treatment results in pathologic growth of vessels in the developing retina that may lead to permanent damage to the retina as well as retinal detachment and macular folds. Administering low concentrations of oxygen can help prevent ROP by reducing the oxygen-induced vasoconstriction and vascular endothelial growth factor (VEGF) expression.

Choice A is not correct because keeping the infant's eyes covered at all times does not prevent ROP. In fact, it may increase the risk of infection or injury to the eyes.

Choice B is not correct because positioning with the head slightly lower than the body does not prevent ROP. It may increase the intracranial pressure and affect the cerebral blood flow.

Choice D is not correct because monitoring arterial oxygen levels with a pulse oximeter does not prevent ROP. It is a useful tool to guide oxygen therapy, but it does not directly affect retinal vascular development.

A. Fundus soft, 2 fingerbreadths below the umbilicus B. Fundus firm, at the level of the umbilicus C. Fundus firm, 2 fingerbreadths above the umbilicus D. Fundus soft, to the right of the umbilicus

Correct Answer is B

Explanation

Fundus firm, at the level of the umbilicus. This is because the normal postpartum uterine fundus location should be around the belly button (umbilicus) one hour after delivery and then decrease by 1 cm per 24 hours. A firm fundus indicates that the uterus is contracting well and preventing bleeding.

Choice A is wrong because a soft fundus indicates uterine atony, which is a risk factor for hemorrhage.

Choice C is wrong because the fundus should not be above the umbilicus 12 hours after delivery.

Choice D is wrong because a fundus to the right of the umbilicus indicates a full bladder, which can displace the uterus and cause bleeding.
