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?
Correct answer
C
Rationale
The correct answer is C: Weak, irregular pulse. Hypokalemia, caused by excessive loss of potassium through vomiting and diarrhea, can lead to cardiac dysrhythmias due to decreased potassium affecting the heart's electrical conduction system. Weak, irregular pulse is a common manifestation of hypokalemia. Extreme thirst (Choice A) is more indicative of dehydration. Hyperactive bowel sounds (Choice B) may be present due to gastrointestinal upset, but it is not a direct result of hypokalemia. Hyperactive reflexes (Choice D) are not typically associated with hypokalemia.
