Answer to Question 1

ANS: D
To prevent warfarin-induced skin necrosis, heparin is given along with the warfarin until a therapeutic and stable international normalized ratio (INR) is obtained.

Answer to Question 2

ANS: A
Fibrinogen levels may drop in DIC, but because fibrinogen is an acute phase reactant it may actually be increased in the presence of an inflammatory process such as sepsis.
