Which of the following are CNS findings of hypoglycemia in newborns?

Lethargy and poor feeding are indeed central nervous system (CNS) findings commonly associated with hypoglycemia in newborns. When a newborn experiences low blood sugar levels, their brain may not receive enough glucose, which is crucial for its energy and proper functioning. This lack of energy often results in lethargy, as the infant may appear less responsive, drowsy, or weak. Poor feeding is also a direct consequence of lethargy; the infant may not have the energy or motivation to feed effectively, leading to inadequate nutritional intake and further complications.

While other options may describe various responses, they do not accurately reflect the typical CNS manifestations seen in newborns suffering from hypoglycemia. In such cases, the priority is recognizing lethargy and poor feeding, as these signs can help healthcare providers intervene promptly to address the newborn's hypoglycemia and prevent serious outcomes.
