Answer to Question 1

ANS: C
Antithrombin covalently binds and inhibits XIIa, XIa, Xa, IXa, and thrombin. It does not bind VIIa.

Answer to Question 2

ANS: C
A decrease of 40 or greater in the platelet count, even if the platelet count remains in the reference range, is evidence for heparin-induced thrombocytopenia. This is a serious consequence, and unfractionated heparin therapy must be immediately stopped and replaced with a direct thrombin inhibitor.
