MRS. oviskan 62 years old has an NG tube and requires liquid potassium to be administered. What should the nurse do first?

• A. Administer potassium via NG tube immediately
• B. Check the latest electrolyte results
• C. Call the physician for orders
• D. Flush the tube with water before administration

Answer: (B)

Before giving potassium via an NG tube, you must verify the patient’s current status with lab data, because potassium is a high‑risk medication and the need for supplementation depends on the latest levels and kidney function. Checking the latest electrolyte results provides the necessary information to decide if supplementation is actually needed and to determine the safe dose, avoiding dangerous imbalances like hyperkalemia. If the results show an abnormal level or no active order, you’d then escalate by contacting the physician, but the first step is to review the labs to guide any further action. Once labs and orders are confirmed, you’d proceed with the administration steps (ensuring the tube is patent and flushing as appropriate).
