A nurse is caring for a client who has type 1 diabetes mellitus. The client reports that she is not feeling well. Which of the following findings should indicate to the nurse that the client is hypoglycemic? (Select all that apply.)

A. Polydipsia (excessive thirst) occurs with hyperglycemia, not hypoglycemia, as the body attempts to dilute elevated blood glucose levels. B. Tremors occur due to activation of the sympathetic nervous system in response to falling glucose levels. C. The brain depends on glucose; decreased levels cause neuroglycopenic symptoms like poor concentration, confusion, or irritability. D. Acetone (fruity) breath odor occurs in diabetic ketoacidosis due to ketone production from fat metabolism, a sign of hyperglycemia, not hypoglycemia. E. Diaphoresis is a hallmark autonomic symptom of hypoglycemia, resulting from catecholamine release.
