Vitamin K
Correct Answer
A. Vitamin KExplanation
Vitamin K is the correct answer because it plays a crucial role in blood clotting. It helps the liver produce clotting factors, such as prothrombin, which are essential for the formation of blood clots. Administering vitamin K before surgery ensures that the liver has an adequate supply of this vitamin, reducing the risk of excessive bleeding during and after the procedure. Vitamin C, vitamin B12, and vitamin D do not have direct effects on blood clotting and are not typically used preoperatively for this purpose.Rate this question:
