Q1 Question 1 of 100
Q1. A 42-year-old female presents with fatigue, pallor, and a hemoglobin of 8.2 g/dL. Bone
marrow biopsy reveals megaloblastic anemia with hypersegmented neutrophils. The
pathophysiologic basis of megaloblastic anemia involves impaired DNA synthesis due to
deficiency of:
A. Iron required for hemoglobin production
B. Vitamin B12 or folate required for thymidine synthesis and DNA replication
C. Vitamin K required for coagulation factor synthesis
D. Copper required for ceruloplasmin function
Correct Answer: C
Rationale:
Megaloblastic anemia results from impaired DNA synthesis caused by vitamin B12 or folate deficiency,
leading to large, immature erythrocytes. Iron deficiency causes microcytic anemia, vitamin K deficiency
causes bleeding, and copper deficiency causes neurologic symptoms.
Q2 Question 2 of 100
Q2. A 35-year-old male with a history of recurrent infections is found to have a genetic
defect in the NADPH oxidase enzyme system in his phagocytes. This defect results in
chronic granulomatous disease, which impairs the ability of phagocytes to:
A. Engulf and internalize bacteria through endocytosis
B. Produce reactive oxygen species needed for intracellular killing of pathogens
C. Present antigens to T lymphocytes via MHC class II molecules
D. Secrete complement proteins that opsonize bacteria
Correct Answer: C
Rationale:
Chronic granulomatous disease results from a defect in NADPH oxidase, which prevents the respiratory
burst needed to generate reactive oxygen species for killing ingested pathogens. Phagocytosis itself and
antigen presentation remain intact, and complement is produced by the liver, not phagocytes.

, Q3 Question 3 of 100
Q3. A 28-year-old female presents with a butterfly rash across her cheeks and nose, joint
pain, and proteinuria. Laboratory testing reveals positive anti-dsDNA antibodies and low
complement levels. The underlying pathophysiologic mechanism in systemic lupus
erythematosus involves:
A. Type I hypersensitivity mediated by IgE antibodies
B. Type II hypersensitivity with antibody-mediated cellular destruction
C. Loss of self-tolerance with production of autoantibodies that form immune complexes
depositing in tissues
D. Type IV delayed hypersensitivity mediated by cytotoxic T lymphocytes
Correct Answer: A
Rationale:
SLE involves loss of self-tolerance leading to autoantibody production, and immune complex deposition
(type III hypersensitivity) in tissues such as the kidney, skin, and joints. Type I involves IgE, type II involves
direct antibody-mediated cell destruction, and type IV is T-cell mediated.
Q4 Question 4 of 100
Q4. A 55-year-old male with a 30-pack-year smoking history develops squamous cell
carcinoma of the lung. The cellular adaptation that most commonly precedes the
development of this malignancy in the bronchial epithelium is:
A. Hyperplasia, an increase in the number of cells
B. Metaplasia, the replacement of one differentiated cell type with another
C. Hypertrophy, an increase in cell size without cell division
D. Dysplia, disordered cell growth with loss of uniformity
Correct Answer: B
Rationale:
Chronic exposure to cigarette smoke causes squamous metaplasia, replacing ciliated columnar epithelium
with squamous epithelium, which is the precursor change that can progress to dysplasia and then
carcinoma. Hyperplasia and hypertrophy do not involve cell type change, and dysplasia follows
metaplasia.

, Q5 Question 5 of 100
Q5. A 48-year-old patient with severe burns develops edema, hypotension, and tachycardia
within hours of injury. The pathophysiologic process responsible for these findings is:
A. Increased capillary permeability and massive fluid shifts from the intravascular to the
interstitial space
B. Decreased aldosterone secretion causing sodium wasting
C. Primary cardiac dysfunction reducing cardiac output
D. Acute renal failure preventing urine output
Correct Answer: B
Rationale:
Severe burns cause massive release of inflammatory mediators that increase capillary permeability,
leading to fluid and protein shifts from the intravascular to the interstitial space, causing edema and
hypovolemic shock. The primary problem is capillary leak, not cardiac or renal dysfunction.
Q6 Question 6 of 100
Q6. A 62-year-old male with prostate cancer presents with bone pain and elevated serum
calcium. Radiographs show lytic bone lesions. The hypercalcemia in this patient is most
likely caused by:
A. Primary hyperparathyroidism from parathyroid adenoma
B. Tumor secretion of parathyroid hormone-related peptide causing osteoclastic bone
resorption
C. Vitamin D toxicity from excessive supplementation
D. Immobilization-induced calcium release from bone
Correct Answer: B
Rationale:
Humoral hypercalcemia of malignancy is commonly caused by tumor secretion of PTHrP, which mimics
PTH and stimulates osteoclastic bone resorption. Primary hyperparathyroidism causes elevated PTH not
PTHrP, vitamin D toxicity is unrelated to cancer, and immobilization alone does not cause this degree of
hypercalcemia.
