The nurse is assessing a newborn. Which sign would indicate hypoglycemia?

A. Increased nasal mucus: Excess nasal mucus is common in newborns and may indicate mild respiratory irritation or congestion, but it is not a sign of hypoglycemia. B. High-pitched cry: A high-pitched cry is a neurologic manifestation of neonatal hypoglycemia. It reflects central nervous system irritability caused by low blood glucose levels, often accompanied by jitteriness, lethargy, or poor feeding. C. Increased temperature: Fever or elevated temperature is not typically associated with hypoglycemia in newborns. Temperature instability may occur with infection but does not indicate low glucose levels. D. Active muscle movements: Active movements generally indicate normal neurologic function. Hypoglycemia often causes jitteriness, hypotonia, or weak movements rather than increased or coordinated activity.
