Jaundiced patients are susceptible to postoperative hemorrhage because their blood does not clot normally due to the fact that:

A Excess bile salts in the blood inhibit synthesis of prothrombin in the liver. B Excess bile salts in the blood inhibit synthesis of vitamin K and prothrombin in the liver. D Lack of bile in the intestine causes inadequate vitamin K absorption, which causes inadequate prothrombin synthesis by the liver. C Decreased bile salts in the blood inactivate prothrombinase and prevent formation of thrombin from prothrombin.
