What should the nurse do when told by the HCP to discontinue potassium chloride due to hyperkalemia?

• A. Discontinue the medication as directed.
• B. Withhold the medication and document.
• C. Continue the medication until lab results confirm.
• D. Increase the dose to compensate for high potassium.

Answer: (A)

Stopping potassium chloride immediately is the priority when hyperkalemia is present. Potassium chloride adds potassium to the body, and in hyperkalemia further administration can worsen the risk of dangerous heart rhythms and other complications. Therefore, the nurse should discontinue the medication exactly as directed, then reassess the patient’s potassium level and monitor the heart rhythm and vitals. Document that the drug was stopped and notify the healthcare provider. Also review for any other potassium sources (other meds, IV fluids, supplements) and ensure ongoing monitoring of labs and ECG to guide further care.
