Practice Question
A nurse is collecting data from a client who has hypokalemia as a result of nausea, vomiting, and diarrhea. Which of the following findings should the nurse expect?
Answer Choices:
Correct Answer:
Weak, irregular pulse
Rationale:
💎 Hypokalemia results in decreased electrical conduction in the heart, leading to cardiac arrhythmias.
💎 Potassium is essential for muscle contraction, including in the heart, and its deficiency can result in a weak, irregular pulse and other dysrhythmias.
💎 Clients with nausea, vomiting, and diarrhea are at increased risk for potassium loss through the gastrointestinal tract.
💎 Early identification of cardiac signs like a weak pulse can help prevent more severe complications such as arrhythmias or cardiac arrest.
