Which food sources should the nurse highlight for a patient limiting vitamin K intake while on anticoagulant therapy?

The focus on limiting vitamin K intake during anticoagulant therapy is crucial because vitamin K can interfere with the effectiveness of these medications, particularly warfarin. While spinach and asparagus are notoriously high in vitamin K, the correct response emphasizes that these foods should be highlighted for a patient needing to manage their intake.

Highlighting potatoes and corn would be less relevant since these foods contain low levels of vitamin K, and informing patients about strawberries and apples would also miss the point, as these fruits similarly do not contribute significantly to vitamin K intake. Pasta and rice, too, are not significant sources of vitamin K.

Therefore, the correct choice underscores the importance of awareness regarding high vitamin K foods for those on anticoagulants, making it valuable for patients to be informed about spinach and asparagus to ensure they manage their vitamin K consumption effectively.
