What symptom should a nurse expect to find in a client with hypokalemia due to diuretic use?

• A. Increased energy levels
• B. Muscle cramps
• C. Fatigue and muscle weakness
• D. Palpitations

Answer: (C)

In a client with hypokalemia, particularly one that results from diuretic use, one of the prominent symptoms is fatigue and muscle weakness. Potassium plays a crucial role in the proper functioning of muscle cells, including those in the skeletal and cardiac muscles. When potassium levels fall, muscle cells cannot function optimally, leading to weakness and fatigue. This is particularly concerning because the heart relies heavily on potassium for maintaining rhythm and contractility, and a deficiency can manifest as profound weakness in the limbs and the respiratory muscles, making it difficult for patients to carry out daily activities. While muscle cramps can occur with hypokalemia, it's the generalized fatigue and muscle weakness that are more prominently reported and that encompass a broader range of muscle involvement. Additionally, palpitations can be a symptom of electrolyte imbalance but are not as directly indicative of the systemic weakness that hypokalemia tends to induce in affected individuals. Increased energy levels would contradict the expected symptoms of hypokalemia, as individuals typically feel weaker and more fatigued due to their low potassium levels.
