NR-507 ADVANCED PATHOPHYSIOLOGY – WEEK 4
MIDTERM EXAM 2026/2027 COMPLETE (100) CURRENT
TESTING QUESTIONS AND CORRECT ANSWERS WITH
DETAILED RATIONALES.
PATHOPHYSIOLOGY
Prepare effectively for the NR-507 Advanced Pathophysiology Week 4 Midterm Exam
with this focused study resource. It supports review of disease processes,
pathophysiological mechanisms, cellular responses, clinical manifestations, and
physiological changes associated with illness. Use the material to reinforce your
understanding, review key topics, and identify areas that may require additional study.
This resource is suited for graduate nursing students, advanced practice nursing
learners, and candidates preparing for the NR-507 Week 4 midterm examination.
MULTIPLE CHOICE.
SECTION 1: CELLULAR ADAPTATION & INJURY (Questions 1–10)
Question #1
A patient with long-standing hypertension presents with an enlarged left
ventricle. This increase in cardiac muscle mass is primarily due to which
cellular adaptation?
A. Hyperplasia
B. Hypertrophy
C. Atrophy
D. Metaplasia
Correct Answer: B
Rationale: Hypertrophy is an increase in cell size leading to organ
enlargement. Cardiac muscle cells are terminally differentiated and cannot
undergo hyperplasia (increase in cell number), so they adapt to increased
workload through hypertrophy. This compensatory mechanism maintains
cardiac output against increased afterload in hypertension.

Question #2
A client who smokes has a change in the bronchial epithelium from ciliated
columnar to stratified squamous epithelium. This represents which type of
cellular adaptation?
A. Hyperplasia
B. Hypertrophy
C. Atrophy
D. Metaplasia
Correct Answer: D
Rationale: Metaplasia is a reversible replacement of one differentiated
cell type by another in response to chronic irritation. In smokers, the normal
ciliated columnar epithelium is replaced by stratified squamous epithelium
that is more resistant to irritants but loses protective ciliary function.
Question #3
Which type of necrosis is most commonly associated with myocardial
infarction?
A. Liquefactive necrosis
B. Caseous necrosis
C. Coagulative necrosis
D. Fat necrosis
Correct Answer: C
Rationale: Coagulative necrosis is characteristic of ischemic injury in
solid organs such as the heart (myocardial infarction), kidney, and liver. The
tissue architecture is preserved but cells are dead, with denatured proteins
preventing enzymatic digestion.
Question #4
Which type of necrosis is characterized by a cheese-like appearance and is
most commonly associated with tuberculosis?

A. Liquefactive necrosis
B. Caseous necrosis
C. Coagulative necrosis
D. Fat necrosis
Correct Answer: B
Rationale: Caseous necrosis (cheese-like) is characteristic of
tuberculosis. It represents a combination of coagulative and liquefactive
necrosis with a granulomatous inflammatory response.
Question #5
Gangrenous necrosis is most commonly associated with which body area?
A. Brain injury
B. Liver injury
C. Lower extremities (ischemia with bacterial infection)
D. Lung infection
Correct 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
Programmed cell death that removes damaged or unnecessary cells without
triggering an inflammatory response is called:
A. Necrosis
B. Ischemia
C. Apoptosis
D. Infarction
Correct Answer: C
Rationale: Apoptosis is programmed cell death that removes damaged or
unnecessary cells without triggering an inflammatory response. This contrasts
with necrosis, which is unprogrammed cell death that triggers inflammation.

Question #7
A patient with chronic alcohol use develops liver cirrhosis. The liver cells
undergo which type of cellular adaptation?
A. Hypertrophy
B. Hyperplasia
C. Atrophy
D. Metaplasia
Correct Answer: C
Rationale: Atrophy is a decrease in cell size and function, often due to
decreased workload, loss of innervation, diminished blood supply, or chronic
disease. In cirrhosis, hepatocytes are replaced by fibrous tissue, leading to
loss of functional liver mass.
Question #8
Reversible cellular injury is characterized by which of the following?
A. Cellular swelling and fatty change
B. Nuclear fragmentation
C. Loss of plasma membrane integrity
D. Release of intracellular enzymes
Correct Answer: A
Rationale: Reversible cellular injury is characterized by cellular swelling
(hydropic change) and fatty change (steatosis) . Nuclear fragmentation, loss
of plasma membrane integrity, and release of intracellular enzymes are
features of irreversible injury and cell death.
Question #9
Which of the following is a hallmark of irreversible cell injury?
A. Cellular swelling
B. Nuclear fragmentation (karyorrhexis)
