Which of the following actions helps to ensure medication accuracy?

Double-checking the medication against the order is crucial in ensuring medication accuracy. This action serves as an important safety measure to confirm that the right medication is being administered to the right patient, at the right dose, and via the correct route. It allows the medication aide to verify that the medication matches what is prescribed in the order, reducing the risk of errors that could harm the patient.

By cross-referencing the medication with the order, the aide can catch potential discrepancies, such as wrong dosages or the use of medications that should not be given together. This step is fundamental in promoting patient safety and effective medication management, aligning with best practices in healthcare.
