What is the best practice for administering client medications?

Following the agreed medication schedule and documenting administration is essential for ensuring clients receive their medications consistently and accurately. Adhering to a prescribed schedule helps maintain the efficacy of the medications and supports the client's health and well-being. It allows for organized care, prevents missed doses, and can help in managing potential side effects. Documentation of medication administration is equally important as it provides a clear record of what has been given, when, and in what dosage. This record can be critical for ongoing assessments of client health, coordination among caregiving staff, and compliance with legal and organizational policies regarding medication management.
