A) Altered hemoglobin synthesis.
B) Altered DNA synthesis.
C) Decreased hemolysis.
D) Bone marrow failure.
Answer: C
The pathophysiological mechanisms of anemia include altered hemoglobin synthesis, altered DNA synthesis, bone marrow failure, and increased hemolysis. Altered hemoglobin synthesis is the mechanism involved in iron deficiency anemia, Thalassemia, and chronic inflammation. Altered DNA synthesis is the mechanism involved in Vitamin B12 malabsorption or deficiency, and folic acid malabsorption or deficiency. Bone marrow failure is the mechanism in aplastic anemia, red cell aplasia, myeloproliferative leukemias, and lymphomas.
