A school nurse is assessing an adolescent who reports feeling shaky and is having difficulty speaking and concentrating on the questions the nurse is asking. The nurse checks the adolescent's blood glucose level and identifies a value of 55 mg/dL. Which of the following findings should the nurse expect?

Rationale: A. Polyuria is a sign of hyperglycemia, not hypoglycemia. B. Tachycardia occurs as part of the adrenergic response to hypoglycemia, along with shakiness, anxiety, and diaphoresis. C. Dry, flushed skin is more consistent with hyperglycemia or dehydration, not hypoglycemia. D. Deep, rapid respirations (Kussmaul respirations) are associated with metabolic acidosis, particularly diabetic ketoacidosis, not hypoglycemia.
