Answer to Question 1

ANS: C
The majority of cases of ITP are due to immune-driven destruction of platelets. It is not due to allergies, hypersplenism, or T-cell injury.

Answer to Question 2

ANS: D
Thrombocythemia is characterized by a platelet count more than 400,000 platelets per cubic mil-limeter of blood and is symptomatic when the count exceeds 1,000,000 platelets per cubic milli-meter, at which time the risk for intravascular clotting (thrombosis) is high. Thrombocythemia is characterized by a high platelet count, not a defective one, a fragmented one, or a consumed one.
