1. Stimulates the breakdown of specific clotting factors by the liver, and it takes 2-3 days for this is exhibit an anticoagulant effect.
2. Inhibits synthesis of specific clotting factors in the liver, and it takes 3 to 4 days for this medication to exert an anticoagulation effect.
3. Stimulates production of the body’s own thrombolytic substances, but it takes 2-4 days for it to begin.
4. Has the same mechanism action of heparin, and the crossover time is needed for the serum level of warfarin sodium to be therapeutic.

2. Slightly deteriorating and should be monitored for another hour
3. Moderately impaired, and the surgeon should be called.
4. Adequate from the arterial approach, but venous complications are arising.
