Question

A nurse is reinforcing teaching with an older adult client who is to start taking warfarin. Which of the following statements indicates the client understands the teaching?

a) "I will take aspirin daily to enhance the anticoagulant effect."
b) "I should avoid foods high in vitamin K, like green leafy vegetables."
c) "I'll stop the medication if I notice any signs of bleeding."
d) "I can take a double dose if I forget a dose the day before."

Answer 1

The client understands the teaching about taking warfarin if they state that they should avoid foods high in vitamin K, like green leafy vegetables.

Step-by-step explanation:

The statement that indicates the client understands the teaching about taking warfarin is b) "I should avoid foods high in vitamin K, like green leafy vegetables." This is because warfarin is an anticoagulant medication that works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver. Therefore, consuming foods high in vitamin K can interfere with the effectiveness of warfarin.
