A nurse is caring for four clients who have drainage tubes, The nurse should identify the client who has which of the following tubes as being at risk for hypokalemia?

Rationale: A. Urinary catheters drain urine but do not typically cause significant electrolyte loss leading to hypokalemia. B. Chest tubes remove air, blood, or fluid from the pleural space but do not significantly affect potassium levels. C. NG (nasogastric) tubes to suction can lead to hypokalemia because they remove gastric contents, which include potassium and other electrolytes. Prolonged suctioning can cause significant electrolyte imbalances. D. Nephrostomy tubes drain urine directly from the kidney and do not typically lead to potassium depletion unless there is a high-output or concurrent renal dysfunction.
