CURRENT TESTING QUESTIONS AND CORRECT
ANSWERS WITH DETAILED RATIONALES.
PATHOPHYSIOLOGY
Prepare effectively for the NR 507 Midterm Exam at Chamberlain with this focused
study resource. It supports review of advanced pathophysiology, disease
mechanisms, cellular changes, clinical manifestations, and physiological responses
across major body systems. Use the material to reinforce your understanding, review
high-yield topics, and identify areas that may require additional study. This resource is
suited for Chamberlain nursing students, nurse practitioner learners, and advanced
practice nursing candidates preparing for the NR 507 midterm examination.
MULTIPLE CHOICE.
SECTION 1: CELLULAR ADAPTATION & INJURY (Questions 1–25)
Question 1:
A patient with long-standing hypertension develops an enlarged left ventricle.
This is an example of which type of cellular adaptation?
A) Hyperplasia
B) Hypertrophy
C) Atrophy
D) Metaplasia
Answer: B
Rationale: Hypertrophy is an increase in cell size leading to organ
enlargement. The left ventricle enlarges in response to increased workload
(hypertension) because cardiac muscle cells cannot divide (hyperplasia).
Question 2:
A patient who smokes has a change in the bronchial epithelium from ciliated
columnar to stratified squamous. This is an example of:

A) Hyperplasia
B) Hypertrophy
C) Atrophy
D) Metaplasia
Answer: D
Rationale: Metaplasia is the reversible replacement of one differentiated cell
type with another. In smokers, chronic irritation causes the bronchial
epithelium to transform from ciliated columnar to stratified squamous
epithelium as a protective adaptation.
Question 3:
A patient with chronic hypoxia due to COPD develops clubbing of the fingers.
This is an example of:
A) Dysplasia
B) Adaptive change (hypertrophy/hyperplasia response to chronic hypoxia)
C) Necrosis
D) Apoptosis
Answer: B
Rationale: Clubbing is a chronic adaptive response to long-term hypoxia,
involving soft tissue proliferation at the nail beds. It is not dysplasia (abnormal
cell growth) or cell death. It reflects the body's attempt to increase capillary
density and oxygen delivery.
Question 4:
Which type of necrosis is typically seen in tuberculosis?
A) Coagulative necrosis
B) Caseous necrosis
C) Liquefactive necrosis
D) Fat necrosis
Answer: B
Rationale: Caseous necrosis ("cheese-like") is characteristic of

granulomatous infections like tuberculosis. It combines features of
coagulative and liquefactive necrosis, forming soft, friable, white debris within
granulomas.
Question 5:
Gangrenous necrosis is most commonly associated with:
A) Brain injury
B) Liver injury
C) Lower extremities (ischemia with bacterial infection)
D) Lung infection
Answer: C
Rationale: Gangrenous necrosis occurs in the lower extremities due to
ischemia (dry gangrene) or with superimposed bacterial infection (wet
gangrene). Gas gangrene is caused by Clostridium bacteria.
Question 6:
What is the most common cause of cellular injury?
A) Physical trauma
B) Hypoxia
C) Chemical exposure
D) Genetic mutations
Answer: B
Rationale: Hypoxia, or oxygen deprivation, is the most common cause of
cellular injury. It can result from ischemia, anemia, or respiratory failure,
leading to ATP depletion and cellular dysfunction.
Question 7:
A patient with a myocardial infarction experiences cell death due to prolonged
ischemia. This type of cell death is best described as:
, Page 4 of 63
A) Apoptosis
B) Necrosis
C) Autophagy
D) Metaplasia
Answer: B
Rationale: Necrosis is unprogrammed cell death resulting from severe injury,
such as ischemia. In myocardial infarction, prolonged ischemia leads to
coagulative necrosis of cardiac muscle cells. Apoptosis is programmed cell
death.
Question 8:
Reactive oxygen species (ROS) cause cellular injury through which
mechanism?
A) Activation of DNA repair enzymes
B) Lipid peroxidation of cell membranes
C) Increased ATP production
D) Inhibition of apoptosis
Answer: B
Rationale: Reactive oxygen species (free radicals) cause cellular injury
primarily through lipid peroxidation of cell membranes, damaging membrane
integrity and function. They can also damage proteins and DNA.
Question 9:
A patient with a history of alcohol abuse develops liver cirrhosis. The liver
cells show fatty accumulation. This is an example of:
A) Hydropic swelling
B) Fatty change (steatosis)
C) Hypertrophy
D) Hyperplasia
Answer: B
Rationale: Fatty change (steatosis) is the accumulation of lipids in
