A nurse is preparing to administer a medication to a client for the first time. Which of the following actions should the nurse take to help ensure safe medication administration?

A. Read the medication label twice prior to administration: Best practice requires reading the label three times (when retrieving, preparing, and before administering), so reading it only twice is insufficient for safety. B. Ask the client if they have ever taken a similar medication: While helpful, this does not replace the need for the nurse to verify the medication's action, side effects, and interactions independently. C. Use one patient identifier prior to medication administration: Safe practice requires using two patient identifiers (e.g., name and date of birth), so using only one is inadequate and unsafe. D. Access the online drug formulary for an unfamiliar medication: This ensures the nurse understands the medication's purpose, dosage, side effects, and contraindications, which is critical for safe first-time administration.
