A nurse is caring for a client who has type 2 diabetes mellitus. Which of the following findings should the nurse identify as manifestations of hypoglycemia?

Rationale A. Dry mucous membranes: Dry mucous membranes are typically a manifestation of dehydration or hyperglycemia, not hypoglycemia. They indicate fluid deficit rather than low blood glucose levels. B. Thirst: Excessive thirst is associated with hyperglycemia and fluid loss due to osmotic diuresis. It is not a common symptom of hypoglycemia and does not indicate low blood glucose. C. Polyuria: Polyuria occurs with hyperglycemia when the kidneys excrete excess glucose in the urine. It is not a feature of hypoglycemia and does not help identify low blood sugar episodes. D. Shakiness: Shakiness or tremors is a classic manifestation of hypoglycemia. It results from adrenergic stimulation as the body responds to low blood glucose levels, prompting sympathetic nervous system activation and symptoms such as sweating, palpitations, and anxiety.
