Which assessment finding indicates a newborn may have hypoglycemia?

A lethargic state in a newborn is indeed a significant indicator of potential hypoglycemia. In newborns, hypoglycemia can manifest through various signs, and lethargy is one of the more noticeable and critical symptoms. It suggests that the infant may not have sufficient glucose to maintain normal brain activity and function, leading to a decreased level of alertness and responsiveness.

Other potential signs of hypoglycemia may include irritability, jitteriness, poor feeding, or even seizures, but lethargy stands out because it can indicate a more severe situation requiring prompt evaluation and intervention.

The yellow sclera is indicative of jaundice, which is related to bilirubin levels and does not directly reflect blood sugar status. Ecchymotic caput succedaneum refers to a type of head swelling that can be caused during delivery and is not linked to blood glucose levels. Frequent urination may reflect other concerns, such as hydration status or kidney function, but is not a direct indicator of hypoglycemia. Understanding these distinctions is vital for prompt and appropriate management in a clinical setting.
