MAR is a system of accountability for which substances?

• A. DEA controlled substances
• B. All medications
• C. Antibiotics only
• D. Medical devices

Answer: (A)

MAR is a record that tracks every dose of drugs administered. The key purpose here is accountability for controlled substances—the drugs regulated by the DEA because of their potential for abuse and diversion. In practice this means strict inventory and control: secure storage, precise sign-out, double-checks, proper disposal of waste, and thorough documentation of every administration. That level of oversight is specific to DEA-controlled substances and isn’t required for all medications, antibiotics, or for medical devices, which is why those options don’t fit. So MAR is used for DEA controlled substances.
