Answer 1

7: Answer is C. Vitamin K

Reason: Warfarin is used to prevent arterial and venous thromboembolism. It is vitamin K antagonist. Warfarin inhibits the activation of the vitamin K dependent clotting factors (Factors II, VII, IX, and X). The anticoagulant effect of warfarin may lead to bleeding. To reverse the anticoagulant effect of warfarin, an oral or intravenous dose of vitamin K is an effective option since it activate the clotting factors II, VII, IX, and X and initiates coagulation.

Option A and B are anticoagulants and worsen the condition of bleeding. Option D is a heparin antagonist.
