Answer to Question 1

ANS: A
Thrombin is considered the most important protease of the coagulation pathway because of its multiple functions. These include splitting fibrinogen to form fibrin monomers; activating the cofactors V and VIII; activating factor XIII; binding to thrombomodulin to activate protein C; and aggregating platelets, to name just a few.

Answer to Question 2

ANS: D
Vitamin K antagonism is the basis for oral anticoagulation.
