Explanation:

Warfarin is an oral anticoagulant effective in the primary and secondary prevention of venous thromboembolism, the prevention of systemic embolism in patients with heart valve prosthesis or atrial fibrillation, and the prevention of stroke, recurrent infarction and death in patients with infarction. myocardial infarction. Although eating fruits and vegetables is good for the body, patients who use this type of medication should avoid changing their diet and need to avoid foods that are rich in vitamin K because this vitamin interferes with Warfarin function. Foods rich in vitamin K should be avoided, green leafy vegetables and some fruits have vitamin K in abundance, so we can conclude that if the patient speaks the phrase "I have started eating more healthy foods like green salads and fruit" is because he is not well informed and needs more teaching.

what are the choices?
