Which MAR field records who administered the medication?

• A. The physician
• B. The nurse or pharmacist
• C. The patient
• D. The nurse's assistant

Answer: (B)

The record of medication administration shows who gave each dose, which is essential for accountability and patient safety. The physician writes and approves the order, but the act of giving the medicine is performed by a licensed professional who administers it, and that person's name or initials appear on the MAR next to the time and dose. The patient does not administer most medications, and a nurse's assistant typically does not have authority to administer meds in many settings. Tracking who administered each dose helps explain any reactions or dosing questions and keeps the care team informed about exactly who delivered the medication.
