Correct answer: C — Take it at the same time daily and attend INR monitoring as arranged

Warfarin requires regular INR monitoring and dose adjustment according to the anticoagulation plan. Taking it at a consistent time helps adherence and makes dose changes easier to manage. Patients should be counselled on bleeding signs, interactions, missed-dose advice, and maintaining a consistent diet rather than avoiding vitamin K foods completely.
