A nurse on a medical-surgical unit is performing medication reconciliation for a newly admitted client. Which of the following actions should the nurse take?

Rationale: A. Compare a list of common medications to treat a condition to the actual prescriptions: This approach does not meet the definition of medication reconciliation, which focuses on comparing the client’s actual prior medications to new orders to prevent errors. B. Compare the prescription to the allergy history of the client: While this is an important safety check, it is not the primary purpose of medication reconciliation. Allergy review is a separate step done for every prescribed medication, not specifically during reconciliation. C. Compare the medication label to the provider's prescription on three occasions before administration: This is part of the "three checks" of medication administration to ensure accuracy and safety, but it is unrelated to the reconciliation process that occurs during admission, transfer, or discharge. D. Compare the client's list of home medications to the admission prescriptions written for the client: This is the central process in medication reconciliation. It ensures continuity of care, prevents omissions, duplications, or interactions, and identifies changes that need clarification.
