Q1 Question 1 of 100
A 55-year-old man with a 30-pack-year smoking history presents with a persistent cough and
weight loss. A lung biopsy reveals cells with large, irregular nuclei and abnormal mitotic figures.
Which cellular adaptation best describes the initial change that preceded malignant transformation?
A. Metaplasia of bronchial epithelium from columnar to squamous type
B. Hyperplasia of alveolar cells
C. Hypertrophy of bronchial smooth muscle
D. Dysplasia of bronchial epithelium
Correct Answer: D
Rationale:
Dysplasia, characterized by abnormal, disorganized cell growth with atypical nuclei and mitotic figures, is the
direct precursor to malignant transformation. Metaplasia is a reversible change from one cell type to another that
may precede dysplasia but is not the immediate precursor. Hyperplasia and hypertrophy are adaptive, not
pre-malignant changes.
Q2 Question 2 of 100
A 40-year-old woman presents with fatigue, pallor, and a hemoglobin of 7.8 g/dL. Peripheral smear
shows microcytic, hypochromic red blood cells. Iron studies reveal low serum ferritin. Which
pathophysiologic mechanism best explains her anemia?
A. Impaired heme synthesis due to insufficient iron for ferrochelatase activity
B. Decreased erythropoietin production by the kidneys
C. Increased red blood cell destruction by the spleen
D. Bone marrow failure reducing erythroid progenitor cells
Correct Answer: A
Rationale:
Iron deficiency anemia results from insufficient iron to support heme synthesis, specifically the
ferrochelatase-catalyzed insertion of iron into protoporphyrin IX. This produces microcytic, hypochromic cells.
Decreased EPO causes normocytic anemia in kidney disease. Splenic destruction causes hemolytic anemia.
Bone marrow failure causes pancytopenia.

, Q3 Question 3 of 100
A 60-year-old man with chronic alcohol abuse presents with jaundice, ascites, and elevated liver
enzymes. A liver biopsy shows hepatocytes with swollen, pale cytoplasm containing Mallory
bodies. Which cellular injury mechanism is most likely occurring?
A. Apoptosis mediated by caspase activation
B. Coagulative necrosis from ischemia
C. Fatty degeneration with intracellular protein accumulation
D. Caseous necrosis from granulomatous inflammation
Correct Answer: C
Rationale:
Mallory bodies (eosinophilic cytoplasmic inclusions) are a hallmark of alcoholic liver disease, representing
intracellular accumulation of damaged intermediate filaments in hepatocytes undergoing fatty degeneration.
Apoptosis does not produce Mallory bodies. Coagulative necrosis preserves tissue architecture. Caseous
necrosis is associated with tuberculosis.
Q4 Question 4 of 100
A 35-year-old woman presents with a butterfly rash across her cheeks and nasal bridge. Laboratory
tests reveal positive ANA and anti-dsDNA antibodies. Which pathophysiologic process is the
primary mechanism driving her disease?
A. Type I hypersensitivity reaction with IgE-mediated mast cell degranulation
B. Type II hypersensitivity with antibody-dependent cellular cytotoxicity
C. Type III hypersensitivity with immune complex deposition in tissues
D. Type IV hypersensitivity with T-cell-mediated tissue damage
Correct Answer: C
Rationale:
Systemic lupus erythematosus is primarily driven by type III hypersensitivity, where autoantibodies form immune
complexes that deposit in tissues (skin, kidneys, joints), activating complement and causing inflammation. The
butterfly rash and anti-dsDNA antibodies are characteristic. Type I involves allergies, type II involves cell
destruction, and type IV is T-cell mediated.

, Q5 Question 5 of 100
A 68-year-old man with atherosclerosis suffers a myocardial infarction. After 24 hours, histologic
examination of the infarcted tissue would most likely reveal which finding?
A. Coagulative necrosis with preservation of tissue architecture
B. Liquefactive necrosis with complete enzymatic digestion
C. Caseous necrosis with granuloma formation
D. Fat necrosis with saponification
Correct Answer: A
Rationale:
Myocardial infarction produces coagulative necrosis, characterized by preservation of tissue architecture with
denatured proteins maintaining cell outlines, typically evident by 12-24 hours. Liquefactive necrosis occurs in the
brain. Caseous necrosis is seen in tuberculosis. Fat necrosis occurs in pancreatic tissue and breast fat.
Q6 Question 6 of 100
A 45-year-old man with cirrhosis develops increased abdominal girth and edema. Paracentesis
reveals a serum-ascites albumin gradient greater than 1.1 g/dL. Which mechanism primarily
contributes to ascites formation in portal hypertension?
A. Splanchnic arteriolar vasodilation triggering activation of the renin-angiotensin-aldosterone system
B. Decreased hepatic lymphatic drainage alone
C. Malignant peritoneal seeding with exudative fluid
D. Protein-losing enteropathy causing hypoalbuminemia
Correct Answer: A
Rationale:
In cirrhosis, portal hypertension causes splanchnic arteriolar vasodilation, which reduces effective arterial blood
volume and activates the RAAS, leading to sodium and water retention and ascites formation. While lymphatic
drainage is impaired, vasodilation and RAAS activation are the primary drivers. Malignancy causes exudative
ascites. Protein-losing enteropathy is a separate condition.
