Correct answer: D — Keep vitamin K intake consistent and attend INR monitoring

Warfarin dosing is guided by INR monitoring, and sudden major changes in vitamin K intake can alter anticoagulant control. Patients should be advised to keep diet consistent rather than avoid vegetables altogether. Extra warfarin doses are unsafe. Aspirin is not a substitute and increases bleeding risk.
