Correct answer: C — Keep INR appointments, maintain consistent alcohol intake and report signs of bleeding promptly.

Warfarin requires INR monitoring and careful counselling about bleeding symptoms, missed doses, alcohol and interacting medicines. Patients should keep dietary vitamin K intake consistent rather than avoiding vegetables completely. Aspirin should not be used routinely without advice because it increases bleeding risk.
