Which RBC index is most useful for identifying microcytosis?

• RDW

• MCHC

• Hemoglobin

• MCV

A decreased MCHC indicates which RBC characteristic?

• Hypochromia

• Anisocytosis

• Poikilocytosis

Which anemia typically shows microcytosis disproportionate to the degree of anemia?

• Anemia of chronic disease

• Aplastic anemia

• Thalassemia

Which condition is not classically considered a microcytic anemia?

• Sideroblastic anemia

• Iron deficiency anemia

• Vitamin B12 deficiency

• Thalassemia

Which form of iron is best absorbed in the gastrointestinal tract?

• Ferric (Fe3+)

• Heme-bound transferrin

• Ferrous (Fe2+)

• Hemosiderin

Most iron used for erythropoiesis comes from:

• Liver storage

• Recycled red blood cells

• Iron supplements

• Dietary intake

Iron is transported in the plasma bound to:

• Hemosiderin

• Transferrin

• Albumin

• Ferritin

Iron is primarily stored in the body as:

• Protoporphyrin and iron

• Heme and globin

• Ferritin and hemosiderin

• Transferrin and albumin

The most common cause of iron deficiency anemia in adults is:

• Genetic mutations

• Chronic blood loss

• Increased iron utilization

• Poor dietary intake

Which stage of iron deficiency shows decreased ferritin but normal hemoglobin?

• Terminal stage
