Anemia
Anemia ( 42 Questions)
This choice is correct. Iron-deficiency anemia may present with an increased number of target cells on the peripheral blood smear, which are red blood cells with a central area of pallor and a surrounding ring of hemoglobin. This appearance is due to a reduced hemoglobin content in relation to cell size.
This choice is incorrect because hemolytic anemia is characterized by the destruction of red blood cells and typically presents with different morphological changes on the peripheral blood smear.
This choice is incorrect because sickle cell anemia is associated with the presence of sickle-shaped cells, not target cells.
This choice is incorrect because aplastic anemia is characterized by a decrease in the number of all formed elements of the blood (red blood cells, white blood cells, and platelets), and it does not typically cause target cells.
