A client admitted with gastroenteritis and a potassium level of 2.9 mEq/dL has been placed on telemetry. Which ECG finding would the nurse expect to find due to the client's potassium results?
Correct answer
A
Rationale
Hypokalemia (2.9 mEq/dL) can cause a depressed ST segment, flattened T waves, and prominent U waves on ECG due to altered cardiac repolarization.
