What is the purpose of the back of the MAR?

The back of the Medication Administration Record (MAR) serves a specific function in the medication administration process, primarily related to documenting medication administration events that occur outside the standard schedule. Recording PRN (as needed) medications, refusals, and omissions is critical for maintaining accurate medical records and ensuring continuity of care.

When medications are not administered as scheduled—due to patient refusal or other reasons such as the medication being omitted—it's essential to have this information documented on the MAR. This allows healthcare providers to keep track of a patient’s medication history and make informed decisions about further medication administration or adjustments in treatment based on the patient’s responses. Additionally, PRN medication administration requires specific documentation to manage the patient's needs effectively and adjust care plans accordingly.

The other options, while relevant to patient care, do not focus on the primary function of the MAR's back side. Documenting side effects, patient instructions, or tracking prescription refills is typically managed through different healthcare documentation processes or tools. Therefore, the correct understanding of the MAR’s purpose directly aligns with the necessity of appropriate documentation practices, particularly encompassing PRN medications, refusals, and omissions.
