YEAR (2026-2027) ALL 300 QUESTIONS AND
CORRECT ANSWERS WITH RATIONALES
MCA 2 HEMATOLOGY EXAM COVERAGE SUMMARY
Exam Focus: Comprehensive Hematology covering erythrocyte disorders, leukocyte disorders,
hemostasis/thrombosis, transfusion medicine, hematologic malignancies, bone marrow failure
syndromes, hemoglobinopathies, coagulation cascade disorders, platelet disorders,
hematologic manifestations of systemic disease, and laboratory diagnostic principles.
Exam Format: 300 randomized multiple-choice questions with scenario-based clinical
presentations, focusing on pathophysiology, diagnosis, treatment, and clinical decision-making.
1. A 45-year-old woman presents with fatigue, pallor, and angular cheilitis. Laboratory findings
show microcytic anemia with elevated RDW and low ferritin. What is the most likely diagnosis?
A) Anemia of chronic disease
B) Iron deficiency anemia
C) Thalassemia trait
D) Sideroblastic anemia
E) Lead poisoning
Answer: B Iron deficiency causes microcytic hypochromic anemia with elevated RDW, low

ferritin, and classic symptoms of fatigue, pallor, and angular cheilitis due to decreased iron
stores.
2. A 72-year-old man with chronic kidney disease has hemoglobin of 8.5 g/dL and hematocrit of
25%. His serum erythropoietin level is inappropriately normal. What is the primary
pathophysiologic mechanism?
A) Decreased iron absorption
B) Impaired erythropoietin production
C) Vitamin B12 deficiency
D) Bone marrow suppression
E) Increased hemolysis
Answer: B Chronic kidney disease leads to decreased erythropoietin production by failing
kidneys, resulting in normocytic normochromic anemia that responds to exogenous
erythropoietin.
3. A 28-year-old woman of Southeast Asian descent has microcytic anemia with hemoglobin of
9.2 g/dL and RBC count of 6.5 million/μL. Iron studies are normal. What is the most likely

diagnosis?
A) Iron deficiency anemia
B) Beta thalassemia trait
C) Alpha thalassemia trait
D) Sickle cell trait
E) Anemia of chronic disease
Answer: C Alpha thalassemia trait presents with microcytic anemia but relatively high RBC
count, normal iron studies, and is common in Southeast Asian populations due to decreased
alpha globin chain synthesis.
4. A 55-year-old man presents with fatigue, paresthesias in his hands and feet, and difficulty
walking. Laboratory findings show macrocytic anemia with hypersegmented neutrophils. What
vitamin deficiency is most likely?
A) Vitamin B6 deficiency
B) Folic acid deficiency
C) Vitamin B12 deficiency
D) Iron deficiency

E) Vitamin C deficiency
Answer: C Vitamin B12 deficiency causes macrocytic anemia with neurologic manifestations
including paresthesias and subacute combined degeneration of the spinal cord, with
characteristic hypersegmented neutrophils.
5. A 32-year-old woman with systemic lupus erythematosus develops hemolytic anemia with
positive direct Coombs test and spherocytes on peripheral smear. What is the most likely
diagnosis?
A) Hereditary spherocytosis
B) Autoimmune hemolytic anemia (warm type)
C) Paroxysmal nocturnal hemoglobinuria
D) Microangiopathic hemolytic anemia
E) Drug-induced hemolytic anemia
Answer: B Warm autoimmune hemolytic anemia is associated with autoimmune diseases like
SLE, presents with positive direct Coombs test, spherocytes, and hemolytic anemia due to IgG
antibodies against RBCs.
