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?

Choice A reason: A weak, irregular pulse is a hallmark sign of hypokalemia. Potassium is essential for normal cardiac conduction and muscle function. Low potassium levels disrupt electrical activity in the heart, leading to arrhythmias, bradycardia, and diminished pulse strength. This finding requires close cardiac monitoring and prompt correction of electrolyte imbalance. Choice B reason: Hyperactive reflexes are not typically associated with hypokalemia. In fact, hypokalemia may lead to decreased reflexes and muscle weakness due to impaired neuromuscular transmission. Choice C reason: Hyperactive bowel sounds are more commonly seen in conditions like diarrhea or early intestinal obstruction. Hypokalemia, especially when caused by prolonged vomiting and diarrhea, often results in decreased gastrointestinal motility and hypoactive bowel sounds. Choice D reason: Extreme thirst is more characteristic of hypernatremia or hyperglycemia. While dehydration from fluid loss may cause thirst, it is not a direct manifestation of hypokalemia and does not help distinguish it clinically.
