Answer to Question 1

ANS: D
This is a key feature of primary myelofibrosis.

Answer to Question 2

ANS: B
Bleeding and thromboembolic complications are characteristic of essential thrombocytosis. Patients with polycythemia vera who are treated only with phlebotomy are at increased risk for bleeding and thrombosis, but it is otherwise not characteristic of polycythemia vera. Splenomegaly is seen in all the myeloproliferative disorders, as are fatigue and infections.
