A nurse is caring for a client who is taking a glucocorticoid.
Which of the following findings should indicate to the nurse the client is experiencing hypokalemia? (Select all that apply.)

Choice A rationale

Muscle weakness is a classic sign of hypokalemia, resulting from decreased neuromuscular excitability. Normal serum potassium levels range from 3.5 to 5.0 mEq/L, with hypokalemia typically defined as levels below 3.5 mEq/L.

Choice B rationale

Hyperactive bowel sounds are more indicative of hyperkalemia due to increased gastrointestinal motility. Hypokalemia generally results in diminished bowel sounds and constipation due to decreased gastrointestinal motility.

Choice C rationale

Tingling of fingers, or paresthesia, is a symptom of hypokalemia affecting the neuromuscular system. The altered potassium levels affect nerve function, leading to sensations such as tingling or numbness.

Choice D rationale

Peaked T waves are a hallmark sign of hyperkalemia, reflecting increased cardiac excitability. Hypokalemia typically presents with flattened or inverted T waves and the presence of U waves on an ECG.

Choice E rationale

Fatigue is a non-specific but common sign of hypokalemia. The reduced potassium levels impair muscle function and cellular processes, leading to generalized weakness and fatigue. .
