What is the primary purpose of documenting the time of administration on the MAR?

• A. To track dosing intervals and ensure timely administration
• B. To determine drug cost
• C. To decide which nurse administers
• D. To calculate stock usage

Answer: (A)

Documenting the exact time a medication is given on the MAR anchors the dosing schedule and ensures doses are administered on time. When the administration time is recorded, the care team can verify that each dose is given at the intended interval, catch late or missed doses, and plan the next dose accordingly. This timing information is crucial for drugs that require strict schedules and supports safe handoffs between shifts, since anyone reading the MAR can see when the last dose occurred and when the next should be due. It isn’t used to determine cost, assign which nurse administers, or track stock usage, which are separate processes. So the primary purpose is to track dosing intervals and ensure timely administration.
