A nurse is assessing a client who has a new diagnosis of diabetes mellitus. The nurse should identify that which of the following findings is a manifestation of hyperglycemia?

Rationale: A. Increased thirst: Polydipsia, or excessive thirst, is a classic symptom of hyperglycemia. It results from the body's attempt to counteract dehydration caused by osmotic diuresis, which occurs when high glucose levels pull fluid into the urine. B. Decreased urine output: Hyperglycemia typically causes polyuria (increased urine output), not decreased. High glucose concentrations in the blood lead to osmotic diuresis, resulting in frequent and excessive urination. C. Moist skin: Hyperglycemia is more often associated with dry skin and mucous membranes due to fluid loss. Moist, clammy skin is more characteristic of hypoglycemia, particularly when it is accompanied by sweating and other adrenergic symptoms. D. Tremors: Tremors are more commonly associated with hypoglycemia due to increased sympathetic nervous system activity. Hyperglycemia usually develops more gradually and does not typically produce tremors.
