Answer

If the patient had adequate iron stores, accelerated production of RBCs occurs, so that 1 week after bleeding, a larger-than-normal number of young RBCs and reticulocytes are circulating in the peripheral blood. Because reticulocytes and young RBCs have a larger volume (MCV of approximately 120), macrocytes may be observed in the peripheral smear, and a slight increase in the MCV occurs.
