The nurse recognizes that a symptom of respiratory distress syndrome (RDS) in an infant is:

Choice A rationale

Placing the newborn in a radiant warmer is appropriate for managing hypothermia but does not directly address the signs of diaphoresis, jitteriness, and lethargy, which are indicative of hypoglycemia.

Choice B rationale

Monitoring the newborn's blood pressure is not the primary action needed for signs of hypoglycemia. The immediate need is to check blood glucose levels and address any hypoglycemia.

Choice C rationale

Initiating phototherapy is a treatment for hyperbilirubinemia (jaundice) and is not related to the signs of diaphoresis, jitteriness, and lethargy seen in hypoglycemia.

Choice D rationale

Obtaining blood glucose by heel stick is the correct action as the signs of diaphoresis, jitteriness, and lethargy are indicative of hypoglycemia. Checking blood glucose levels will help in diagnosing and managing the condition.

Choice B rationale: Prolactin is the hormone responsible for the production of breast milk. It does not determine the caloric content of the milk released later in the feeding.

Choice C rationale: Foremilk is the initial milk released during breastfeeding. It is higher in water content and lower in calories compared to hindmilk.

Choice D rationale: Hindmilk is the milk released later in the feeding. It is richer in fat and calories, providing essential nutrients and energy to the baby. The higher fat content in hindmilk helps in the baby's growth and development.
