Which actions should the nurse take when reconstituting and administering powdered medications to ensure patient safety? (Select all that apply)

A. Use verbal prescriptions for non-emergency situations without proper documentation. Prepare medications for multiple clients simultaneously to save time is incorrect because verbal orders should be limited to emergencies and must be read back and documented immediately. Preparing medications for multiple patients at once increases the risk of medication errors and compromises patient safety. B. Label the vial with the date and time of preparation, expiration date, and nurse's initials is correct because proper labeling ensures accurate identification, tracking, and safe use of reconstituted medications. This step prevents administration errors and ensures the medication is used within the recommended stability period. C. Add the correct type and amount of diluent per manufacturer instructions is correct because using the appropriate diluent and volume ensures the medication is at the correct concentration. Improper reconstitution can lead to incorrect dosing, reduced efficacy, or adverse effects. D. Check the medication label against the MAR before administration is correct because verifying the medication against the Medication Administration Record (MAR) ensures that the right drug, dose, route, and patient are correct. This is a critical safety step to prevent errors.
