Answer to Question 1

ANS: D
Thrombotic thrombocytopenia purpura, hemolytic uremic syndrome, and DIC are all examples of MAHAs. An antibody against platelets causes immune thrombocytopenia purpura, and only the platelet count is affected. No anemia exists unless the patient is bleeding because of the low platelet count; if the bleeding is occult, then this eventually could result in iron deficiency anemia but not MAHA.

Answer to Question 2

ANS: B
Paroxysmal nocturnal hemoglobinuria is an acquired disorder that can be shown to be clonal in nature. Some patients have two populations of red cells: (1) normal and (2) defective.
