Why must CMAs check compatibility with the MAR before administering a medication?

• A. To determine insurance coverage.
• B. To check patient preference.
• C. To confirm the medication order matches the MAR and avoid errors.
• D. To decide which nurse is assigned.

Answer: (C)

The important idea here is to verify that what’s on the MAR matches the physician’s order so the right drug is given correctly. The MAR is the bedside record listing every medication to be administered, including the drug name, dose, route, and time. By cross-checking the order with the MAR before giving a dose, you catch discrepancies such as a changed dose, a discontinued medication still listed, or a different route or time than what the order specifies. This careful check helps prevent medication errors and protects patient safety. Other factors like insurance coverage, patient preference, or which nurse is assigned don’t ensure that the exact medication, dose, route, and timing are being followed, and they don’t prevent mismatches with the current orders. If you notice any difference, you should seek clarification before proceeding.
