Answer to Question 1
4. It always requires treatment with folic acid.
Rationale:
Hemolytic anemia is more common with aging and is caused by the premature destruction of the red blood cells. The normal life span of a red blood cell is 120 days. All hemolytic anemias require treatment with folic acid because this vitamin is consumed by the increased bone marrow production of red blood cells in response to the anemia.It is not associated with blood loss. There is an increase, not a decrease, in the reticulocyte (immature red blood cells) count because they are released early from the bone marrow to compensate. Hemolytic anemias are normocytic (red blood cells are normal size), not microcytic.
