Question 1 of 5
The mean cell volume of the patient is 90 fl and the reticulocyte production index is low. Which of the following is the most possible cause of anemia in this patient?
Correct Answer: C
Rationale: A mean cell volume (MCV) of 90 fL indicates normocytic anemia (80-100 fL). A low reticulocyte production index suggests reduced bone marrow response. Aplastic anemia (C) causes normocytic anemia with low reticulocytes due to marrow failure. Thalassemia (A) is typically microcytic, vitamin B12 deficiency (B) is macrocytic, sideroblastic anemia (D) can be microcytic or macrocytic, and iron deficiency (E) is microcytic—none match normocytic with low reticulocytes as well as aplastic anemia.
Question 2 of 5
Myelodysplastic syndromes are a group of clonal stem cell disorders. Which of the following type has the poorest prognosis according to the FAB system of classifications?
Correct Answer: D
Rationale: In the FAB classification of myelodysplastic syndromes, RA with excess blasts in transformation (D, RAEB-T, >20% blasts) has the poorest prognosis due to high risk of AML progression. RA (A) and RA with ring sideroblasts (B) are low-risk, RAEB (C) is intermediate, and CMML (E) varies—RAEB-T is worst.
