Q1 Question 1 of 50
A 58-year-old male with a 30-pack-year smoking history presents with a chronic cough and a
bronchoscopic biopsy revealing altered epithelium in his bronchi. The pathologist notes that the
normal ciliated columnar epithelium has been replaced by stratified squamous epithelium. The nurse
recognizes that this cellular adaptation is best classified as which of the following?
A. Metaplasia as a reversible substitution of one differentiated cell type for another
B. Hyperplasia as a response to chronic irritation
C. Dysplasia as an atypical proliferation indicating preneoplastic change
D. Hypertrophy as an increase in cell size to compensate for stress
Correct Answer: A
Rationale:
Metaplasia is the reversible replacement of one differentiated cell type with another more resilient to chronic stress,
such as stratified squamous epithelium replacing ciliated columnar epithelium in the bronchi of smokers. Hyperplasia
involves an increase in cell number, not cell type change. Dysplia involves disordered growth with atypical cells
suggesting preneoplastic change, and hypertrophy involves increased cell size rather than a change in cell type.
Q2 Question 2 of 50
A 42-year-old female with a history of uncontrolled hypertension undergoes an echocardiogram that
reveals a thickened left ventricular wall with normal cavity size. The cardiologist explains that this
change is an adaptive response to increased afterload. The nurse understands that the primary
cellular mechanism driving this finding is which of the following?
A. An increase in the size of individual cardiac myocytes through hypertrophy
B. An increase in the number of cardiac myocytes through hyperplasia
C. A change from cardiac muscle to smooth muscle through metaplasia
D. An accumulation of lipid droplets within the myocytes through fatty degeneration
Correct Answer: A
Rationale:
The thickened left ventricular wall with normal cavity size in response to chronic pressure overload (hypertension)
represents concentric hypertrophy, where individual cardiac myocytes increase in size by adding sarcomeres in
parallel. Cardiac myocytes are terminally differentiated and cannot undergo hyperplasia. Metaplasia does not occur in
cardiac muscle, and fatty degeneration would weaken rather than adapt the myocardium.

, Q3 Question 3 of 50
A 65-year-old male who sustained a myocardial infarction 3 weeks ago has a follow-up biopsy of the
infarcted area. The pathologist identifies coagulative necrosis with loss of nuclei and preserved
tissue architecture. The nurse understands that coagulative necrosis is most characteristic of injury
from which mechanism?
A. Liquefactive dissolution by hydrolytic enzymes from neutrophils
B. Ischemic hypoxia causing protein denaturation while preserving tissue architecture
C. Enzymatic digestion by lipases transforming tissue into a liquid mass
D. Calcium deposition in dead tissue leading to dystrophic calcification
Correct Answer: B
Rationale:
Coagulative necrosis is the hallmark of ischemic injury in most tissues except the brain, where protein denaturation
from hypoxia causes the cellular proteins to coagulate and maintain the tissue architecture in a firm, opaque state
while the nuclei are lost. Liquefactive necrosis involves enzymatic dissolution (typical of brain and abscesses), fat
necrosis involves lipase action on adipose tissue, and dystrophic calcification is a secondary change in necrotic
tissue, not the primary necrotic process.
Q4 Question 4 of 50
A 50-year-old male with chronic alcohol abuse presents with an enlarged, tender liver. A liver biopsy
reveals hepatocytes swollen with clear cytoplasm and centrally located nuclei. Special staining
confirms intracellular lipid accumulation. The nurse recognizes that this pathologic change is best
described as which of the following?
A. Steatosis representing intracellular accumulation of triglycerides in hepatocytes
B. Hydropic degeneration from acute cellular swelling
C. Glycogen storage disease causing carbohydrate accumulation
D. Amyloidosis resulting from extracellular protein deposition
Correct Answer: A
Rationale:
Steatosis (fatty change) is the intracellular accumulation of triglycerides in hepatocytes, commonly caused by chronic
alcohol abuse, which impairs beta-oxidation of fatty acids and increases triglyceride synthesis. The clear cytoplasm
with centrally located nuclei is the classic histologic appearance of lipid-laden hepatocytes. Hydropic degeneration
involves water accumulation from membrane pump failure, glycogen storage disease is a genetic disorder of
carbohydrate metabolism, and amyloidosis involves extracellular protein deposition.
