A nurse is teaching a newly licensed nurse about medication reconciliation. The nurse should instruct the newly licensed nurse to perform medication reconciliation for which of the following clients?

A. A client who is transported to radiology: Transporting a client to radiology is a temporary transfer for diagnostic purposes, not a change in level of care or medication responsibility. Medication reconciliation is not required in this situation. B. A client who has a consultation for physical therapy: A physical therapy consultation does not involve medication administration or changes, so medication reconciliation is unnecessary in this case. C. A client who has a referral for social services: Social services referrals address psychosocial or discharge needs, not medication management. Therefore, medication reconciliation is not performed at this point. D. A client who is transferred to a step-down unit: Medication reconciliation must be completed during any transition of care, including transfers between units. This process ensures continuity, prevents omissions or duplications, and identifies potential medication errors.
