A client who is a vegetarian has a new prescription for warfarin. The client reports eating green leafy vegetables every day. How should the nurse respond?

A. Advise the client that the healthcare provider (HCP) needs to be made aware of the current diet: Green leafy vegetables are high in vitamin K, which can interfere with the effectiveness of warfarin by promoting clotting. The healthcare provider must be informed to adjust the medication dose if necessary or provide specific dietary guidance.B. Suggest that the client replace the leafy vegetables with a protein source such as nuts or beans: Advising the client to eliminate green vegetables is not appropriate because sudden changes in vitamin K intake can destabilize warfarin therapy. Consistency in vitamin K consumption is key rather than abrupt dietary changes.C. Confirm that the client's diet choices will help the medication be more effective in preventing blood clots: Regular consumption of vitamin K-rich foods without dose adjustment can decrease warfarin's anticoagulant effect, increasing the risk of clot formation. The current diet does not inherently support the intended action of the medication.D. Commend the client for a healthy lifestyle and encourage the client to continue current diet habits: Although a diet rich in vegetables is generally healthy, with warfarin therapy, any vitamin K intake must be consistent and properly managed. Simply encouraging the client without notifying the provider could lead to therapeutic failure.
