What information should be included on a medication administration record (MAR)?

The correct answer emphasizes the comprehensive details necessary for a medication administration record (MAR), which is critical for ensuring proper medication management in assisted living settings. Including the patient's name ensures that the medication is administered to the correct individual, avoiding potential medication errors. The medication name is vital for identifying what is being given, while the dosage specifies how much of the medication is to be administered, which is essential for safety and efficacy.

The route of administration is equally important as it informs caregivers on how the medication should be given, whether orally, intravenously, or through another method. Additionally, specifying the time of administration is crucial for maintaining medication schedules and adherence, as many medications are time-sensitive.

Finally, the signature of the administering staff provides a record of accountability and verification. This is particularly important in care settings where multiple professionals may be involved in a patient's care to ensure that medications are administered as prescribed and that all documentation is accurate and up to date. Thus, option C provides a complete and appropriate set of information necessary for efficient and safe medication management.
