Which client is most at risk for hypokalemia?

• A. A client with diarrhea
• B. A client with an NG tube to suction
• C. A client on a potassium supplement
• D. A client with diabetes mellitus

Answer: (B)

A client with an NG tube to suction is most at risk for hypokalemia because gastric suction can lead to the loss of electrolytes, including potassium. The stomach secretes gastric juices that contain potassium, and when these secretions are continuously removed through suction, especially over a prolonged period, the body can lose significant amounts of potassium. This can lead to decreased serum potassium levels, resulting in hypokalemia. In addition, factors like the use of medications (such as diuretics) and dietary intake can also influence potassium levels, but in the case of clients with an NG tube to suction, the direct loss of gastric contents exacerbates the risk for hypokalemia significantly. Managing electrolyte levels in patients with NG tubes is critical, and monitoring for symptoms of hypokalemia is essential in these cases.
