Answer to Question 1

ANS: A
Lack of vitamin K, not D, E, or B12, interferes with clotting.

Answer to Question 2

ANS: B
Intravascular clotting leads to depletion of clotting factors. DIC is due to depletion of clotting factors, not activation of prothrombin. Activation of clotting associated with DIC leads to in-flammation, but inflammation does not cause DIC. TF is activated during DIC.
