The electronic medication system alerts the nurse that the medication dose scanned for the client is two times higher than the dose prescribed. Which action should the nurse implement?

A. Withhold the medication until the exact dose is available is not the best first action. The nurse should first report the discrepancy to ensure that the prescribed dose is correct and to confirm if the medication should be withheld or adjusted. B. Calculate the dose on hand to match the prescribed dose is not appropriate. The nurse should not attempt to adjust the medication dose without confirmation from the healthcare provider or pharmacist. C. Report a mismatch of prescribed and available doses is the correct action. The nurse should immediately report the discrepancy to the pharmacist or healthcare provider to verify the correct dose and prevent potential harm to the client. D. Ask the pharmacist if another dose can be dispensed is an appropriate follow-up action but is secondary to reporting the mismatch first. The nurse needs to clarify the prescription and dosage before taking further steps.
