Answer to Question 1

Ans:
D

Feedback:

While hypertension may accompany polycythemia vera, the primary goal of treatment is to control the increase in blood viscosity that accompanies the disease. Polycythemia vera is not associated with increased corpuscular volume, and oxygen distribution is not a priority problem.

Answer to Question 2

Ans:
D

Feedback:

Prevention of trauma is important. ASA and other NSAIDs that affect platelet function should be avoided. Factor VIII replacement therapy administered at home has reduced the typical musculoskeletal damage. Wrapping with a bandage will not prevent damage. Warm compression will extend the bleed.
