The nurse is caring for a newborn who is 18 inches long, weighs 4 pounds, 14 ounces (2.2 kg), has a head circumference of 13 inches (33 cm), and a chest circumference of 10 inches (25.4 cm). Based on these physical findings, assessment for which condition has the highest priority?

Hypoglycemia is a common concern for newborns with low birth weight. Their glucose reserves are limited, and they have a higher metabolic rate, making them prone to low blood sugar levels. Choice B rationale Polycythemia, an increased red blood cell count, is not typically a primary concern based on the measurements given. It is more commonly associated with conditions like delayed cord clamping or maternal diabetes. Choice C rationale Hyperthermia is not a primary concern based on the provided measurements. Thermoregulation issues might arise, but initial focus should be on managing glucose levels. Choice D rationale Hyperbilirubinemia, or jaundice, can occur in newborns but is not the immediate priority based on the given physical findings. Monitoring and managing blood sugar levels is more critical in the initial hours after birth.
