covering advanced pathophysiology topics: cellular injury, inflammation, genetics, cancer,
cardiovascular, respiratory, renal, neuro, endocrine, GI, etc.
Q1. A patient with chronic hypertension develops left ventricular hypertrophy. Which
cellular adaptation best describes this change?
A) Atrophy
B) Hyperplasia
C) ✓ Hypertrophy
D) Metaplasia
Hypertrophy is an increase in cell size. In hypertension, increased workload causes cardiac
myocytes to enlarge, leading to ventricular wall thickening.
Q2. The replacement of normal esophageal squamous epithelium with columnar
epithelium in Barrett's esophagus is an example of:
A) Dysplasia
B) ✓ Metaplasia
,C) Anaplasia
D) Hyperplasia
Metaplasia is a reversible change where one mature cell type is replaced by another, often
due to chronic irritation. Barrett’s esophagus is a classic example.
Q3. A patient with a myocardial infarction has elevated troponin levels 6 hours after
chest pain onset. This indicates:
A) Reversible cell injury
B) ✓ Irreversible cell injury and necrosis
C) Apoptosis
D) Inflammation only
Cardiac troponins are intracellular proteins released only when myocardial cells undergo
necrosis, confirming irreversible cell death.
Q4. Caseous necrosis is most characteristically associated with which condition?
A) Myocardial infarction
B) Stroke
C) ✓ Tuberculosis
D) Acute pancreatitis
Caseous necrosis, a form of necrosis with a cheese-like appearance, is typical of
granulomatous inflammation caused by Mycobacterium tuberculosis.
,Q5. A patient with prolonged ischemia to the kidney would most likely exhibit which
type of necrosis?
A) Liquefactive
B) ✓ Coagulative
C) Caseous
D) Fat
Coagulative necrosis occurs in solid organs (except brain) when ischemia denatures
structural proteins, preserving tissue architecture.
Q6. Which form of cell death is programmed, energy-dependent, and does not elicit
an inflammatory response?
A) Necrosis
B) ✓ Apoptosis
C) Pyroptosis
D) Autophagy
Apoptosis is a regulated, ATP-requiring process of cell suicide that eliminates cells without
causing inflammation.
Q7. A patient with alcoholism presents with confusion, ataxia, and nystagmus.
Deficiency of which vitamin is most likely responsible?
A) Vitamin B12
, B) ✓ Thiamine (Vitamin B1)
C) Vitamin D
D) Vitamin A
Wernicke encephalopathy results from thiamine deficiency, common in alcoholism, and
presents with the classic triad of confusion, ataxia, and ophthalmoplegia/nystagmus.
Q8. The hallmark of irreversible cell injury is:
A) Cellular swelling
B) Ribosomal detachment
C) ✓ Mitochondrial dysfunction and loss of membrane integrity
D) Fatty change
Irreversible injury is marked by severe mitochondrial damage, inability to produce ATP, and
loss of plasma membrane integrity, leading to cell death.
Q9. Which cellular organelle is most vulnerable to hypoxic injury?
A) Ribosomes
B) Golgi apparatus
C) ✓ Mitochondria
D) Smooth ER
Mitochondria require oxygen for oxidative phosphorylation; hypoxia rapidly depletes ATP,
causing failure of energy-dependent processes.
