Final answer:
b. Reticulocytes.
Basophilic macrocytes on a peripheral blood cell film usually indicate increased numbers of reticulocytes.
Step-by-step explanation:
The presence of basophilic macrocytes on a peripheral blood cell film usually indicates increased numbers of
a. Codocytes.
b. Reticulocytes.
c. Metarubricytes.
d. Dacryocytes.
Basophilic macrocytes are enlarged red blood cells with basophilic staining properties. They are commonly observed in certain types of anemias, such as megaloblastic anemia, where there is impaired DNA synthesis resulting in larger and poorly differentiated red blood cells.
Therefore, the correct option is b. Reticulocytes as they are immature red blood cells that can exhibit basophilic staining.
