Answer to Question 1

ANS: B
Thrombotic thrombocytopenic purpura is characterized by thrombocytopenia, a microangiopathic hemolytic anemia with schistocytes (red cell fragments), and neurologic abnormalities. It is most common in women 30 to 40 years of age.

Answer to Question 2

ANS: D
Heparin is associated with drug-induced thrombocytopenia; this is called heparin-induced thrombocytopenia, and it can have serious thrombotic complications. Warfarin does not affect the platelet count. Aspirin and ibuprofen both effect platelet function.
