A nurse in a provider's office is collecting data from a client who takes furosemide daily for heart failure. Which of the following findings is a manifestation of hypokalemia?

Rationale: A. Increased bowel sounds are more commonly associated with conditions like diarrhea or early bowel obstruction, not hypokalemia. B. Numbness in the feet is more characteristic of peripheral neuropathy or hypocalcemia, not a typical early sign of hypokalemia. C. A positive Trousseau's sign indicates hypocalcemia, not hypokalemia. D. Reports of fatigue are a common and early manifestation of hypokalemia due to muscle weakness and decreased cellular function resulting from low potassium levels.
