Answer to Question 1

ANS: C
The symptoms of PV are due to increased blood viscosity, the erythrocyte count is elevated, there will be decreased blood flow to tissues and organs but vessel injury does not occur.

Answer to Question 2

ANS: A
Treatment of PV is phlebotomy to reduce red cell mass and blood volume; increasing blood volume will increase symptoms as will the administration of additional cells and iron replacement therapy.
