A nurse is admitting a term newborn to the nursery following a cesarean birth. The nurse observes that the newborn's skin is slightly yellow. This finding indicates the newborn is experiencing a complication related to which of the following?

Choice A reason:

Stop breastfeeding. This is the correct answer because newborns and infants with galactosemia cannot metabolize galactose, a sugar found in milk and lactose-containing formulas, including breast milk. Galactose can build up in their blood and cause serious complications such as liver damage, cataracts, brain damage, and even death. Therefore, the therapeutic management for this newborn is to stop breastfeeding and switch to a soy or elemental formula that contains no galactose.

Choice B reason:

Add amino acids to the breast milk. This is incorrect because adding amino acids to breast milk will not prevent the accumulation of galactose in the newborn's blood. Amino acids are the building blocks of proteins, not sugars. Adding amino acids to breast milk will not change its galactose content or help the newborn metabolize it.

Choice C reason:

Substitute a lactose-containing formula for breast milk. This is incorrect because lactose is a disaccharide composed of glucose and galactose. Lactose-containing formulas will also expose the newborn to galactose, which they cannot break down. Lactose-containing formulas should be avoided in newborns and infants with galactosemia.

Choice D reason:

Give the appropriate enzyme along with breast milk. This is incorrect because there is no enzyme therapy available for galactosemia. Galactosemia is caused by a genetic defect in one of the enzymes involved in the breakdown of galactose, such as galactose-1-phosphate uridyltransferase (GALT), galactokinase (GALK), or uridine diphosphate galactose-4-epimerase (GALE). Giving an enzyme along with breast milk will not correct this defect or prevent the harmful effects of galactose accumulation.

Choice A reason:

Heat facilitates the drainage of mucus for a premature newborn. This is incorrect because heat does not affect mucus drainage. Mucus drainage is more related to suctioning and hydration.

Choice B reason:

The newborn has a small body surface for his weight. This is incorrect because a small body surface area for weight would indicate a large newborn, not a premature one. A large newborn would have less risk of heat loss than a small one.

Choice C reason:

The newborn's temperature control mechanism is immature. This is correct because premature newborns have immature thermoregulation and are prone to hypothermia. Placing the newborn in an incubator helps maintain a stable temperature and prevent further complications.

Choice D reason:

Heat increases the flow of oxygen to the newborn's extremities. This is incorrect because heat does not directly affect oxygen delivery. Oxygen delivery is more related to ventilation, perfusion, and hemoglobin levels. The question is about a premature newborn who has signs of respiratory distress, such as nasal flaring, intercostal retractions, expiratory grunting, and mild cyanosis. These signs indicate that the newborn is having difficulty breathing and may have a condition such as respiratory distress syndrome, transient tachypnea of the newborn, or meconium aspiration syndrome. The nurse should place the newborn in an incubator to provide warmth and prevent heat loss, which can worsen respiratory distress. The nurse should also monitor the newborn's vital signs, oxygen saturation, blood gases, chest x-ray, and neonatal abstinence scoring system if indicated. The nurse should be prepared to administer oxygen, surfactant, or mechanical ventilation as ordered.
