A nurse calculates a medication dose that differs from the amount available in the unit-dose system. After completing the calculation, what is the nurse's best next action to ensure safe medication administration?

Have a second nurse verify the calculation before preparing and administering the medication.

Administer the medication without verification because the calculation was done by a licensed nurse.

Discard the medication and request a new dose from the pharmacy without verifying calculations.

Prepare the medication immediately to save time.
