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)

Rationale: A. Inability to concentrate: Hypoglycemia reduces glucose availability to the brain, leading to cognitive changes such as difficulty concentrating, confusion, or irritability. This neurologic symptom is an early and common indicator of low blood glucose. B. Tremors: Trembling or shakiness occurs due to autonomic nervous system activation in response to low blood glucose. Catecholamine release stimulates muscle activity, making tremors a classic sign of hypoglycemia. C. Acetone breath odor: Acetone or “fruity” breath is associated with diabetic ketoacidosis (DKA), a complication of hyperglycemia rather than hypoglycemia. It indicates fat metabolism due to insulin deficiency, not low blood glucose. D. Diaphoresis: Profuse sweating is a sympathetic nervous system response to hypoglycemia. It often accompanies other adrenergic symptoms such as palpitations, anxiety, and tremors, signaling low blood sugar. E. Polydipsia: Excessive thirst is a symptom of hyperglycemia and is not associated with hypoglycemia. It occurs when high blood glucose leads to osmotic diuresis and fluid loss.
