and Correct Answers
Instructions
This comprehensive examination consists of multiple-choice
questions covering all major topics in NUR 2063 Pathophysiology. The
assessment covers cellular adaptations, injury and death, inflammation and
immunity, fluid and electrolyte balance, acid-base disorders, genetics,
neoplasia, and system-specific pathophysiology. Each question is designed to
test critical thinking and clinical application. Select the single best answer for
each question.
Question 1
A patient with chronic gastroesophageal reflux disease (GERD) develops
Barrett's esophagus. The esophageal squamous epithelium is replaced by
intestinal-type columnar epithelium. This process is an example of:
• A) Dysplasia
• B) Hyperplasia
• C) Metaplasia
• D) Neoplasia
• E) Hypertrophy
Answer: C) Metaplasia
Rationale: Metaplasia is the reversible replacement of one differentiated cell
type with another that is better able to withstand chronic stress. In Barrett's
esophagus, chronic acid exposure causes the esophageal squamous epithelium
,to be replaced by intestinal-type columnar epithelium, which is more resistant
to acid but carries an increased risk of malignancy. Dysplasia is disorganized
and precancerous growth. Neoplasia is new, uncontrolled growth.
Question 2
A patient suffers a myocardial infarction. Which type of necrosis is most
characteristic of ischemic injury in the heart?
• A) Liquefactive necrosis
• B) Caseous necrosis
• C) Coagulative necrosis
• D) Fat necrosis
• E) Gangrenous necrosis
Answer: C) Coagulative necrosis
Rationale: Coagulative necrosis is the most common type of necrosis caused
by ischemia or infarction in solid organs (heart, kidney, spleen). The
architecture is preserved for several days due to protein denaturation.
Liquefactive necrosis occurs in the brain (high lipid content) and abscesses.
Caseous necrosis is characteristic of tuberculosis. Fat necrosis occurs in
pancreatic tissue.
Question 3
A patient is diagnosed with apoptosis. Which characteristic distinguishes
apoptosis from necrosis?
• A) Apoptosis is characterized by cell shrinkage and membrane
blebbing. Necrosis is characterized by cell swelling and membrane
rupture.
• B) Apoptosis is characterized by cell swelling and membrane blebbing.
Necrosis is characterized by cell shrinkage and membrane rupture.
• C) Apoptosis is characterized by cell shrinkage and membrane rupture.
Necrosis is characterized by cell swelling and membrane rupture.
, • D) Apoptosis is characterized by cell swelling and membrane rupture.
Necrosis is characterized by cell shrinkage and membrane blebbing.
• E) Apoptosis and necrosis are characterized by the same cellular
changes.
Answer: A) Apoptosis is characterized by cell shrinkage and membrane
blebbing. Necrosis is characterized by cell swelling and membrane
rupture.
Rationale: Apoptosis is programmed cell death characterized by cell
shrinkage, chromatin condensation, membrane blebbing, and formation of
apoptotic bodies. It does not trigger inflammation. Necrosis is unprogrammed
cell death characterized by cell swelling, organelle dysfunction, membrane
rupture, and release of cellular contents that trigger inflammation.
Question 4
A patient with chronic hypertension develops left ventricular hypertrophy.
This is an example of:
• A) Pathologic hypertrophy
• B) Physiologic hypertrophy
• C) Hyperplasia
• D) Metaplasia
• E) Dysplasia
Answer: A) Pathologic hypertrophy
Rationale: Pathologic hypertrophy occurs in response to increased workload
or stress and can lead to cellular dysfunction and heart failure. Physiologic
hypertrophy occurs in response to normal growth or exercise. Left ventricular
hypertrophy due to chronic hypertension is a classic example of pathologic
hypertrophy.
, Question 5
A patient develops a cerebral infarction (stroke). Which type of necrosis is
most likely to occur in the brain?
• A) Coagulative necrosis
• B) Liquefactive necrosis
• C) Caseous necrosis
• D) Fat necrosis
• E) Gangrenous necrosis
Answer: B) Liquefactive necrosis
Rationale: Liquefactive necrosis occurs in the brain due to its high lipid
content and enzymatic digestion. The affected tissue is transformed into a
liquid mass (cyst) that may eventually be phagocytized. Coagulative necrosis
occurs in solid organs such as the heart and kidneys.
Question 6
A patient with tuberculosis develops a granuloma in the lung. The type of
necrosis seen in tuberculous granulomas is:
• A) Coagulative necrosis
• B) Liquefactive necrosis
• C) Caseous necrosis
• D) Fat necrosis
• E) Gangrenous necrosis
Answer: C) Caseous necrosis
Rationale: Caseous necrosis is characteristic of tuberculosis and certain
fungal infections. The necrotic tissue has a cheese-like appearance (caseous =
cheese-like) and is surrounded by granulomatous inflammation. It is a
combination of coagulative and liquefactive necrosis.
