Before administering liquid potassium via NG tube, which action is most appropriate first?

• A. Confirm the order with the physician
• B. Check the latest electrolyte results
• C. Dilute potassium in juice
• D. Administer with water immediately

Answer: (B)

When giving potassium through an NG tube, the safety priority is knowing the patient’s current potassium status. Checking the latest electrolyte results is the best first step because it shows whether replacement is even needed and guides the correct dose—avoiding unnecessary or excessive potassium that could lead to dangerous hyperkalemia. Once you have the lab results, you can verify the order and plan the administration with proper dilution and tube care. Diluting potassium in juice isn’t routinely appropriate, and giving it with water without first confirming the lab status and dosing can be unsafe.
