Answer #1

Hematocrit is defined as the volume of red blood cells in total volume of blood. Anemia is a condition of decreased levels of hemoglobin. Increase of hematocrit of Ted from 45 to 50% increases the blood viscosity. This is because, increased hematocrit contributes the viscosity. less is the hematocrit, the blood viscocity is decreased and blood is diluted. Increased blood viscosity increases the resistance of blood flow. Therefore, the factor contributing to increased hematocrit of Ted would be administration of erythropoietin. Thus, option 2 is correct.
