Question

sienna is to start taking warfarin, a blood thinner. which piece of dietary advice is most appropriate for her?
○ a. it is important to avoid all vitamin k - containing foods.
○ b. if she eats a salad every day, she should continue to eat a salad every day.
○ c start to drink a glass of milk every day.
○ d. consume plenty of vitamin e - rich foods such as plant oils, nuts, and seeds

Explanation:

Warfarin is a blood thinner, and vitamin K affects blood clotting (Warfarin works by blocking vitamin K - dependent clotting factors). However, patients on Warfarin are advised to maintain a consistent intake of vitamin K - containing foods (not avoid all, as that can cause instability in INR), but if they have a regular intake (like a salad daily), continuing that consistency is key. Option a is wrong as avoiding all vitamin K foods isn't advised. Option c (milk) and d (vitamin E - rich foods) are not related to Warfarin's mechanism. So option b is appropriate as consistent vitamin K intake (by continuing the salad if she already eats it daily) helps keep the Warfarin's effect stable.

Answer:

b. If she eats a salad every day, she should continue to eat a salad every day.
