Question

Polycythemia vera is a chronic disorder of the bone marrow in which excessive amounts of red blood cells and platelets are produced. What does this put patients at risk for?

A) Thrombosis
B) Anemia
C) Leukopenia
D) Bleeding disorders

Answer 1

Patients with polycythemia vera are at increased risk for thrombosis due to excessive production of red blood cells and platelets leading to a higher than normal amount of clotting, which may cause unwanted blood clots.

Step-by-step explanation:

Polycythemia vera is a condition where the bone marrow produces excessive amounts of red blood cells (RBCs) and platelets.

This overproduction can lead to a condition called thrombocytosis, characterized by a high platelet count, which increases the risk of thrombosis, the formation of unwanted blood clots. Thrombosis is a serious condition that can be potentially fatal if clots form in critical areas, such as the lungs, heart, or brain.

The disease also results in increased blood viscosity, making it harder for the heart to pump blood, which can raise blood pressure and cause complications.
