A nurse is preparing to administer a medication to a client. Using the rights of medication administration, which of the following actions should the nurse take to ensure the right medication is administered to the client?

Correct Answer: B - Use two client identifiers prior to administering the medication.

Rationale: Using two client identifiers ensures that the right medication is administered to the correct client. By verifying the client's identity using two unique identifiers such as their name and date of birth, the nurse minimizes the risk of administering the medication to the wrong person. This step is crucial in preventing medication errors and ensuring patient safety.

Other choices:
A: Asking another nurse to check the medication dosage is a good practice for double-checking accuracy but does not specifically ensure the right medication is administered.
C: Documenting the medication name after administration is important for record-keeping but does not prevent errors in medication administration.
D: Verifying a written order with the medication administration record is essential but does not directly ensure the right medication is administered to the correct client.
