MULTIPLE CHOICE.
SECTION 1: HEMATOLOGIC DISORDERS (Questions 1–25)
Question 1: A patient presents with fatigue, pallor, and pica. Laboratory
findings reveal microcytic, hypochromic anemia with low ferritin and elevated
TIBC. This presentation is most consistent with:
A. Pernicious anemia
B. Iron deficiency anemia
C. Anemia of chronic disease
D. Sickle cell anemia
Correct answer: B. Iron deficiency anemia
Rationale: Iron deficiency anemia is characterized by decreased iron
availability for erythropoiesis due to blood loss, inadequate intake/absorption,
or increased demand. Laboratory findings include microcytic, hypochromic
RBCs, low ferritin, low serum iron, and elevated TIBC. Pica is a classic clinical
feature .

Question 2: A 65-year-old patient presents with macrocytic anemia,
paresthesia, and ataxia. Laboratory findings reveal an elevated MCV, low
serum B12, and positive anti-intrinsic factor antibodies. This is most
consistent with:
A. Iron deficiency anemia
B. Pernicious anemia
C. Sickle cell anemia
D. Thalassemia
Correct answer: B. Pernicious anemia
Rationale: Pernicious anemia is a vitamin B12 deficiency caused by lack of
intrinsic factor, often autoimmune in origin. It presents with macrocytic
anemia (elevated MCV) and neurologic symptoms (paresthesia, ataxia) due to
B12's role in myelin synthesis. Positive anti-intrinsic factor antibodies confirm
the diagnosis .
Question 3: A patient with sickle cell anemia presents with sudden onset of
severe pain in the chest, fever, and cough. This complication is most
consistent with:
A. Vaso-occlusive crisis
B. Acute chest syndrome
C. Aplastic crisis
D. Splenic sequestration
Correct answer: B. Acute chest syndrome
Rationale: Acute chest syndrome is a life-threatening complication of sickle
cell anemia characterized by chest pain, fever, cough, hypoxia, and new
infiltrates on chest X-ray. It is caused by vaso-occlusion in the pulmonary
microvasculature and can rapidly progress to respiratory failure .
Question 4: The pathophysiology of sickle cell anemia involves:
A. Autosomal dominant defect in alpha-globin gene
B. Autosomal recessive defect in beta-globin gene with HbS formation and
RBC sickling under low oxygen conditions

C. X-linked recessive defect in hemoglobin synthesis
D. Acquired defect in RBC membrane stability
Correct answer: B. Autosomal recessive defect in beta-globin gene with
HbS formation and RBC sickling under low oxygen conditions
Rationale: Sickle cell anemia is caused by an autosomal recessive defect in
the β-globin gene, resulting in hemoglobin S (HbS). Under low oxygen
conditions, HbS polymerizes, causing RBC sickling, hemolysis, and vaso-
occlusive complications .
Question 5: A patient with immune thrombocytopenia purpura (ITP) would
most likely present with:
A. Elevated platelet count with thrombosis
B. Isolated low platelet count with petechiae, purpura, and mucosal bleeding
C. Anemia with jaundice and splenomegaly
D. Leukocytosis with fever and fatigue
Correct answer: B. Isolated low platelet count with petechiae, purpura,
and mucosal bleeding
Rationale: ITP is an autoimmune disorder characterized by autoantibody-
mediated destruction of platelets, leading to isolated thrombocytopenia.
Clinical features include petechiae, purpura, and mucosal bleeding. Platelet
count is low, but other cell lines are typically normal .
Question 6: A patient with polycythemia vera (PV) has a JAK2 mutation
causing uncontrolled RBC production. Which of the following is a
complication of PV?
A. Hemolytic anemia
B. Thrombotic events
C. Bone marrow failure
D. Vitamin B12 deficiency
Correct answer: B. Thrombotic events
Rationale: Polycythemia vera is a myeloproliferative neoplasm with JAK2
mutation causing uncontrolled RBC production. The increased hematocrit

and blood viscosity significantly increase the risk of thrombotic events
(stroke, MI, DVT). Clinical features include pruritus, erythromelalgia, and
splenomegaly .
Question 7: A patient with acute lymphoblastic leukemia (ALL) would most
likely present with:
A. Insidious onset with fatigue in older adults
B. Abrupt onset with marked signs and complications in children
C. Painless lymphadenopathy with B symptoms
D. Bone pain and anemia in adolescents
Correct answer: B. Abrupt onset with marked signs and complications in
children
Rationale: Acute leukemias (ALL and AML) have a high proportion of very
immature nonfunctional cells (blast cells) in bone marrow and peripheral
circulation. Onset is usually abrupt with marked signs and complications. ALL
occurs primarily in children and younger adults .
Question 8: What is the most common cause of anemia in hospitalized
patients?
A. Iron deficiency anemia
B. Anemia of chronic disease
C. Pernicious anemia
D. Hemolytic anemia
Correct answer: B. Anemia of chronic disease
Rationale: Anemia of chronic disease is the most common cause of anemia
in hospitalized patients. It is associated with chronic inflammation, infection,
or malignancy and is characterized by normal to low ferritin, low serum iron,
and low TIBC. Inflammatory cytokines impair erythropoiesis and iron
utilization .
