Q1 Question 1 of 150
A 58-year-old male with a 30-year history of cigarette smoking presents with chronic bronchitis.
Bronchial biopsy reveals patches of stratified squamous epithelium replacing the normal
pseudostratified ciliated columnar epithelium. What cellular adaptation does this finding represent?
A. Hyperplasia from increased hormonal stimulation of the bronchial mucosa
B. Atrophy due to decreased workload on the airway
C. Metaplasia as a reversible substitution of one differentiated cell type for another
D. Dysplasia marked by disordered cellular maturation and atypia
Correct Answer: A
Rationale:
Metaplasia is the reversible substitution of one adult differentiated cell type for another, here columnar
to squamous in response to chronic smoke injury. Dysplasia implies disordered maturation and atypia,
while hyperplasia increases cell number without changing cell type.
Q2 Question 2 of 150
A 72-year-old female with severe aortic stenosis is found on echocardiography to have a markedly
thickened left ventricular wall with normal chamber dimensions. Which mechanism best accounts for
this finding?
A. Hyperplasia from increased hormonal signaling on cardiac myocytes
B. Hypertrophy produced by an increase in cell size in response to pressure overload
C. Atrophy caused by diminished workload on the ventricular myocardium
D. Metaplasia reflecting replacement of myocytes by fibroblasts under stress
Correct Answer: B
Rationale:
Pressure overload from aortic stenosis triggers cardiac myocyte hypertrophy, an increase in individual
cell size, since adult myocytes cannot divide by hyperplasia. Hyperplasia would require cell division,
which adult cardiac muscle cannot achieve.

, Q3 Question 3 of 150
A 45-year-old male presents with unilateral testicular atrophy following mumps orchitis at age 19.
Light microscopy would most likely reveal a predominant pattern of cell death involving which
process?
A. Caseous necrosis forming a cheesy white mass surrounded by granulomatous inflammation
B. Coagulative necrosis preserving tissue architecture with protein denaturation
C. Apoptosis characterized by chromatin condensation and absence of inflammation
D. Liquefactive necrosis with neutrophil infiltration and enzymatic tissue destruction
Correct Answer: C
Rationale:
Slow, sustained tissue atrophy after viral injury proceeds largely through apoptosis, an
energy-dependent, gene-regulated process with chromatin condensation and non-inflammatory cell
deletion. Coagulative necrosis is typical of ischemic infarcts, not chronic atrophy.
Q4 Question 4 of 150
A 62-year-old male experiences sudden occlusion of the left anterior descending coronary artery.
Histologic examination of the infarcted myocardium 24 hours later most likely shows which pattern of
cell death?
A. Fat necrosis with chalky-white deposits of calcium soap formation
B. Caseous necrosis with granulomatous inflammation and central amorphous debris
C. Liquefactive necrosis with neutrophil enzymatic digestion of myocardium
D. Coagulative necrosis with preserved tissue architecture and loss of nuclei
Correct Answer: D
Rationale:
Ischemic injury to solid organs such as the heart produces coagulative necrosis, in which cell
architecture is preserved but nuclei are lost and proteins are denatured. Liquefactive necrosis
predominates in the brain and in abscesses.

, Q5 Question 5 of 150
A 56-year-old alcoholic presents with severe epigastric pain and elevated serum lipase. CT imaging
shows peripancreatic fat stranding with scattered dull white chalky deposits. Which mechanism
produces this appearance?
A. Fibrinoid necrosis of small vessel walls in severe acute pancreatitis
B. Liquefactive necrosis from neutrophil release of proteases
C. Fat necrosis following pancreatic lipase release forming calcium soaps
D. Caseous necrosis from mycobacterial infection of peripancreatic tissue
Correct Answer: A
Rationale:
Acute pancreatitis releases lipase that hydrolyzes triglycerides, generating fatty acids that combine
with calcium to form chalky-white soap deposits characteristic of fat necrosis. Coagulative and
liquefactive patterns do not produce calcium soaps.
Q6 Question 6 of 150
A 35-year-old female with systemic lupus erythematosus develops rapidly progressive
glomerulonephritis. Renal biopsy reveals glomerular capillary walls with smudgy, eosinophilic,
fibrin-like material. Which process best describes this vascular change?
A. Coagulative necrosis of glomerular capillary endothelium from ischemia
B. Fibrinoid necrosis involving immune complex deposition and plasma protein leakage
C. Liquefactive necrosis of the glomerular tuft from neutrophil infiltration
D. Fat necrosis of afferent arterioles from dyslipidemia in nephrotic syndrome
Correct Answer: B
Rationale:
Fibrinoid necrosis is the smudgy eosinophilic deposition of plasma proteins, especially fibrin, in
damaged vessel walls, characteristic of immune-mediated vasculitis such as lupus nephritis.
Coagulative necrosis would not selectively target vessel walls.
