Which of the following anemias is classified as a macrocytic-normochromic anemia?
A) Iron deficiency anemia
B) Pernicious anemia
C) Sideroblastic anemia
D) Hemolytic anemia

Question

Quizplus · Accepted Answer

Pernicious anemia is a macrocytic-normochromic anemia caused by a deficiency in vitamin B12, which is required for normal erythrocyte production. In this type of anemia, erythrocytes are abnormally large, but hemoglobin content is normal. Iron deficiency anemia (A) is a microcytic-hypochromic anemia, where erythrocytes are abnormally small and pale in color. Sideroblastic anemia (C) is a type of microcytic-hypochromic anemia where there is a failure in heme synthesis, leading to increased iron accumulation in the erythrocyte precursors. Hemolytic anemia (D) is a normocytic-normochromic anemia, where erythrocytes are normal in size and color but have a shortened lifespan.
