Question

A patient that has recently been placed on warfarin has been asked how many leafy green vegetables that they consume in a week. This is because the doctor is concerned about a possible ______ issue.

a. drug-disease
b. drug-dietary supplement
c. drug-nutrient
d. drug-laboratory

Answer 1

The doctor is concerned about a possible drug-nutrient issue. Leafy green vegetables contain vitamin K, which can interfere with the effectiveness of warfarin, a blood thinning medication.

Step-by-step explanation:

The doctor is concerned about a possible drug-nutrient issue. When a patient takes warfarin, which is a blood thinning medication, they need to be cautious about consuming too many leafy green vegetables. Leafy greens contain vitamin K, which can interfere with the effectiveness of warfarin. Since warfarin works by decreasing the clotting ability of the blood, consuming a lot of vitamin K-rich foods can counteract its effects.
