A nurse is reviewing the laboratory results of a client who is taking a loop diuretic and notes the client's potassium level is 3.0 mEq/L. Which of the following physiological responses should the nurse expect related to the client's hypokalemia?

A. Cardiac dysrhythmias: Hypokalemia disrupts cardiac conduction and increases the risk of potentially life-threatening dysrhythmias - this is an expected physiologic response. B. Hyperreflexia: Low potassium usually causes muscle weakness and reduced reflexes rather than increased reflex activity. C. Polyuria: While some electrolyte disturbances affect urine output, hypokalemia more commonly contributes to urinary concentrating defects in some cases but is not the primary expected physiologic response listed here. D. Increased appetite: Changes in appetite are not a typical physiologic response to hypokalemia.
