A nurse is reinforcing teaching with a client who has peripheral vascular disease and a new prescription for warfarin. Which of the following client statements indicates an understanding of the teaching?

A. "I will eat a consistent amount of green vegetables.": Green vegetables are high in vitamin K, which can affect warfarin’s anticoagulant effect. Maintaining a consistent intake helps keep INR levels stable and prevents fluctuations in blood clotting risk. This demonstrates proper understanding of dietary management while on warfarin. B. "I will continue to take aspirin for pain relief.": Aspirin can increase the risk of bleeding when taken with warfarin because both affect platelet function. Clients on warfarin are advised to avoid NSAIDs or aspirin unless specifically approved by their healthcare provider. Continuing aspirin without guidance is unsafe. C. "I will keep using my straight-edge razor to shave.": Using a straight-edge razor increases the risk of cuts and bleeding while on warfarin. Electric razors are recommended to minimize skin injury and potential complications. D. "I should discontinue my regular exercise regimen.": Exercise is generally encouraged to maintain circulation and overall cardiovascular health. Discontinuing activity is unnecessary unless there is a specific contraindication. Stopping exercise does not prevent warfarin-related risks and is not advised.
