Sample Question 1
What is the mechanism of action of warfarin?

Warfarin works by increasing the production of clotting factors

Warfarin inhibits the synthesis of vitamin K–dependent clotting factors X, IX, VII, and II. This is absorbed easily orally, but is also involved in many drug interactions. This remains the drug of choice for treatment of deep vein thrombosis (DVT) and pulmonary embolus (PE).

Warfarin acts by directly inhibiting platelet aggregation

Warfarin functions by activating antithrombin III

Sample Question 2
How do anticoagulants like Heparin work?

Anticoagulants work by increasing blood clotting factors.

Anticoagulants work by directly dissolving blood clots.

Heparin binds with antithrombin II and inactivates factors IXA, XA, XIIA, and XIII. Heparin is given either intravenously or subcutaneously and is extensively protein bound. Heparin also has drug interactions but not as many as warfarin.

Anticoagulants work by activating platelets to prevent clot formation.

Sample Question 3
What type of medication is Rivaroxaban?

Heparin is a type of antidepressant medication.

Rivaroxaban is an oral medication that acts as a factor XA inhibitor

Aspirin is a type of anticoagulant medication that inhibits platelet aggregation.

Warfarin is an anticoagulant that acts by inhibiting vitamin K epoxide reductase.
