A nurse is caring for a client who is prescribed warfarin therapy for an artificial heart valve. Which of the following laboratory values should the nurse monitor for a therapeutic effect of warfarin?

Bleeding time
Prothrombin time (PT)

The Correct Answer is C
warfarin inhibits vitamin K epoxide reductase interfering with the synthesis of vitamin K dependent clotting factors (II, VII, IX, and X).
