QUESTIONS 1–150
Question 1
A patient develops sustained hypoxia during an episode of severe respiratory
failure. Which cellular adaptation is most likely to occur initially in tissues exposed
to reduced oxygen availability?
A. Increased oxidative phosphorylation
B. Increased anaerobic glycolysis
,C. Increased mitochondrial calcium uptake
D. Increased protein synthesis
🔴 Correct Answer: B. Increased anaerobic glycolysis.
🔵 Explanation: Reduced oxygen limits oxidative phosphorylation, so cells increase
anaerobic glycolysis to maintain limited ATP production. This produces lactate and
contributes to intracellular acidosis.
Question 2
A patient with prolonged hypertension develops left ventricular hypertrophy.
Which cellular adaptation best explains this finding?
A. Hyperplasia of cardiomyocytes
B. Hypertrophy of cardiomyocytes
C. Metaplasia of cardiac muscle
D. Atrophy of cardiac muscle
🔴 Correct Answer: B. Hypertrophy of cardiomyocytes.
🔵 Explanation: Cardiomyocytes have limited capacity for cell division. Chronic
pressure overload therefore produces hypertrophy, characterized by increased cell
size and myocardial mass.
Question 3
A patient with chronic gastroesophageal reflux develops replacement of normal
distal esophageal squamous epithelium with intestinal-type columnar epithelium.
This process represents:
A. Dysplasia
B. Hyperplasia
C. Metaplasia
D. Hypertrophy
🔴 Correct Answer: C. Metaplasia.
🔵 Explanation: Metaplasia is a reversible substitution of one differentiated cell type
for another better suited to persistent stress. Chronic reflux can produce intestinal
metaplasia of the esophagus.
Question 4
A biopsy demonstrates disorganized cellular growth with abnormal nuclear
morphology and loss of normal tissue architecture. Which finding most strongly
suggests dysplasia?
,A. Uniformly enlarged cells responding to workload
B. Replacement by a mature alternate cell type
C. Abnormal cellular maturation and organization
D. Temporary reduction in cellular metabolic activity
🔴 Correct Answer: C. Abnormal cellular maturation and organization.
🔵 Explanation: Dysplasia involves abnormal cellular maturation, architecture,
nuclear features, and organization. It can represent a precursor to malignant
transformation.
Question 5
Which cellular change is most characteristic of reversible cellular injury caused by
decreased ATP production?
A. Cellular swelling
B. Nuclear fragmentation
C. Plasma membrane rupture
D. Extensive lysosomal digestion
🔴 Correct Answer: A. Cellular swelling.
🔵 Explanation: ATP depletion impairs the sodium-potassium pump, causing
intracellular sodium and water accumulation. Cellular swelling is a classic early
manifestation of reversible injury.
Question 6
A patient experiences myocardial ischemia followed by restoration of coronary
blood flow. Despite reperfusion, myocardial injury worsens. Which mechanism
contributes significantly to this phenomenon?
A. Reduced oxygen radical generation
B. Increased reactive oxygen species formation
C. Complete inhibition of inflammatory signaling
D. Permanent suppression of calcium influx
🔴 Correct Answer: B. Increased reactive oxygen species formation.
🔵 Explanation: Reperfusion can generate reactive oxygen species, activate
inflammation, and promote calcium-mediated injury, resulting in additional cellular
damage.
Question 7
Which mechanism most directly explains irreversible cellular injury?
, A. Mild reduction in ATP
B. Temporary cellular swelling
C. Severe mitochondrial dysfunction with membrane damage
D. Reversible ribosomal detachment
🔴 Correct Answer: C. Severe mitochondrial dysfunction with membrane
damage.
🔵 Explanation: Irreversible injury is associated with profound mitochondrial
dysfunction and loss of membrane integrity, resulting in failure of essential cellular
processes.
Question 8
A patient develops ischemic tissue necrosis following arterial occlusion. Which
type of necrosis is most commonly associated with ischemia in solid organs such
as the heart and kidney?
A. Liquefactive
B. Coagulative
C. Fat
D. Fibrinoid
🔴 Correct Answer: B. Coagulative.
🔵 Explanation: Coagulative necrosis is typical of ischemic injury in most solid
organs except the brain. Protein denaturation preserves tissue architecture
temporarily.
Question 9
A patient has an acute cerebral infarction. Which form of necrosis is expected?
A. Coagulative
B. Caseous
C. Liquefactive
D. Fat
🔴 Correct Answer: C. Liquefactive.
🔵 Explanation: Brain ischemia characteristically produces liquefactive necrosis
because enzymatic digestion rapidly destroys the affected tissue.
Question 10
A patient with pancreatic injury develops chalky white deposits in peripancreatic
fat. Which process is most likely responsible?
