Which foods should be avoided or monitored due to interaction with warfarin?

  1. Spinach, broccoli, and kale

  2. Bananas, apples, and oranges

  3. Bread, rice, and pasta

  4. Milk, cheese, and yogurt

The correct answer is: Spinach, broccoli, and kale

Foods high in vitamin K such as spinach, broccoli, and kale should be avoided or monitored with warfarin because they can affect the blood's ability to clot. Bananas, apples, oranges, bread, rice, pasta, milk, cheese, and yogurt do not have interactions with warfarin. However, it is important to maintain a balanced and consistent diet while taking warfarin to ensure the proper dosage of the medication.
