单选题 A neonate of a client with type 1 diabetes mellitus is at high risk for hypoglycemia. An initial sign the nurse should recognize as indicating hypoglycemia in a neonate is
A. peripheral acrocyanosis.
B. bradycardia.
C. lethargy.
D. jaundice.

【正确答案】 C

【答案解析】Lethargy in the neonate may be seen with hypoglycemia because of a lack of glucose in the nerve cells. Peripheral acrocyanosis is normal in the neonate because of immature capillary function. Tachycardia, not bradycardia, is seen with hypoglycemia. Jaundice isn't a sign of hypoglycemia.
