A nurse is preparing a client for discharge home after an admission for bilateral pulmonary emboli. The client is prescribed warfarin in addition to regular daily medications. Which of the following actions should the nurse take?

A. Taking all medications together can increase the risk of drug interactions, especially with warfarin’s narrow therapeutic index. B. Cranberry juice can increase the anticoagulant effect of warfarin, raising bleeding risk. C. Consulting the pharmacist ensures a thorough review of potential drug–drug or drug–food interactions, crucial for warfarin therapy management and client safety. D. Over-the-counter medications (e.g., NSAIDs, aspirin, certain herbal supplements) can potentiate bleeding and should be used only with provider approval.
