Question

prothrombin time is used to measure what therapy?
fibrinogen
coumadin
warfarin
coagulation

Explanation:

Prothrombin time (PT) is a blood test that measures how long it takes for blood to clot. Warfarin is an anticoagulant (blood - thinner) drug. PT is used to monitor the effectiveness of warfarin therapy. Coumadin is a brand - name for warfarin. Fibrinogen is a protein involved in clotting, but PT is not specifically for measuring fibrinogen therapy. Coagulation is a general process, and PT is more specifically tied to warfarin (Coumadin) monitoring.

Answer:

C. Warfarin
