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 the nurse implement?

A. Ask the pharmacist if another dose can be dispensed: Contacting the pharmacist may be necessary if the medication cannot be safely adjusted from what is available. However, if the dose can be accurately calculated and prepared from the current supply, this is not the most immediate action. B. Report a mismatch of prescribed and available doses: Reporting discrepancies is part of medication safety protocols, but it does not address the immediate need to prepare and administer the correct prescribed dose for the client. C. Withhold the medication until the exact dose is available: Delaying administration without attempting to adjust from the available supply could result in treatment delays, which may be harmful, especially for time-sensitive medications. D. Calculate the dose on hand to match the prescribed dose: Using dosage calculation to prepare the exact prescribed amount ensures safe medication administration and avoids overdosing. This is the most immediate action when the available form contains more than the required dose.
