A nurse is preparing to administer medication to a client. Which of the following actions should the nurse take?

Rationale: A. Ensure the medication is administered within 3 hr of the scheduled time: Medications should typically be administered within 30 minutes before or after the scheduled time, not within 3 hours. Administering too early or too late can reduce therapeutic effectiveness or cause harm, depending on the medication type. B. Use two identifiers to verify the client’s identity: Verifying identity with two identifiers—such as name and date of birth—ensures the right client receives the right medication. This practice aligns with the “five rights” of medication administration and is a critical step in preventing medication errors. C. Document administration of the client’s routine medications at the beginning of the shift: Documentation should occur immediately after medication administration, not beforehand. Charting in advance increases the risk of errors and creates false records if the medication is delayed or omitted. D. Check the label of the medication twice prior to administration: The nurse must check the medication label three times—when removing it from storage, before preparing it, and immediately before administration. Checking only twice does not meet safety standards.
