The Correct Answer is A
A. Enoxaparin. Enoxaparin is a low molecular weight heparin used for prophylaxis against DVT. It works by inhibiting clotting factors and is commonly used postoperatively to prevent DVT formation.
B. Alteplase (tPA): Alteplase is a thrombolytic agent used to dissolve clots and is not used for DVT prophylaxis.
C. Warfarin: Warfarin requires monitoring and has a delayed onset, making it less suitable for immediate postoperative DVT prophylaxis.
D. Clopidogrel: Clopidogrel is an antiplatelet agent and is not typically used for DVT prophylaxis postoperatively.
