An accurate description of anemia is:
a. Increased blood viscosity.
b. Depressed hematopoietic system.
c. Presence of abnormal hemoglobin.
d. Decreased oxygen-carrying capacity of blood.
ANS: D
Anemia is a condition in which the number of red blood cells or hemoglobin concentration is reduced below the normal values for age. This results in a decreased oxygen-carrying capacity of blood. Increased blood viscosity is usually a function of too many cells or of dehydration, not of anemia. A depressed hematopoietic system or abnormal hemoglobin can contribute to anemia, but the definition depends on the deceased oxygen-carrying capacity of the blood.
