A nurse is assessing a client who has hypokalemia as a result of nausea, vomiting, and diarrhea. Which of the following findings should the nurse expect?

A. Weak, irregular pulse is a classic sign of hypokalemia. Low potassium levels affect cardiac muscle function, leading to dysrhythmias and reduced cardiac output. B. Hypokalemia typically causes hypoactive reflexes, not hyperactive ones. C. Hypokalemia leads to decreased gastrointestinal motility, so bowel sounds are usually hypoactive, not hyperactive. D. Extreme thirst is more commonly associated with hypernatremia or dehydration, not specifically hypokalemia.
