Question

Scott's blood test shows that he has excess red blood cells. Identify and describe two causes of this disorder.

A) Hemophilia and Leukopenia
B) Anemia and Thrombocytopenia
C) Polycythemia and Dehydration
D) Sickle Cell Anemia and Hemochromatosis

Answer 1

Dehydration and polycythemia vera are two causes of excess red blood cells (polycythemia).

Step-by-step explanation:

Excess red blood cells, or an elevated RBC count, is known as polycythemia. Two causes of this disorder are dehydration and a bone marrow disease called polycythemia vera. Dehydration can lead to transient polycythemia, where the elevated RBC count is a result of inadequate water intake or excessive water losses. On the other hand, polycythemia vera is a rare disease that causes an excessive production of immature erythrocytes.
