NSG 3280 PATHOPHYSIOLOGY FOR NURSES – EXAM 1 (2026)
• This guide contains 100+ multiple-choice questions with five answer options
each, covering all major pathophysiology concepts tested on Exam 1, with
the correct answer clearly marked and a detailed EXPERT RATIONALE
explaining the underlying physiology.
• For best results, attempt each question on your own first, then check the
bolded correct answer and read the EXPERT RATIONALE carefully to
reinforce the "why" behind each concept rather than just memorizing the
answer.
Question 1: A nurse is reviewing the concept of cellular adaptation. Which
term describes an increase in the size of individual cells, leading to an
increase in the size of the affected organ?
A. Atrophy
B. Hyperplasia
C. Hypertrophy
D. Metaplasia
E. Dysplasia
Correct Answer: C. Hypertrophy EXPERT RATIONALE: Hypertrophy refers to
an increase in the size of individual cells without an increase in cell number, which
results in an enlarged organ. This is commonly seen in cardiac muscle in response
to hypertension (left ventricular hypertrophy) or in skeletal muscle with resistance
training. Atrophy is a decrease in cell size, hyperplasia is an increase in cell number,
metaplasia is the reversible replacement of one cell type with another, and
dysplasia refers to abnormal cell growth and differentiation.
,Question 2: Which type of cellular adaptation involves an increase in the
number of cells in an organ or tissue?
A. Hypertrophy
B. Atrophy
C. Hyperplasia
D. Dysplasia
E. Necrosis
Correct Answer: C. Hyperplasia EXPERT RATIONALE: Hyperplasia is defined as
an increase in the number of cells in an organ or tissue, usually resulting from
increased cellular division. This is seen physiologically in the proliferation of breast
and uterine tissue during pregnancy, and pathologically in conditions like benign
prostatic hyperplasia. It differs from hypertrophy, which involves enlargement of
existing cells rather than an increase in their number.
Question 3: A patient's bronchial epithelium changes from ciliated columnar
cells to squamous cells after years of smoking. This is an example of:
A. Hypertrophy
B. Hyperplasia
C. Atrophy
D. Metaplasia
E. Anaplasia
Correct Answer: D. Metaplasia EXPERT RATIONALE: Metaplasia is the
reversible replacement of one differentiated cell type with another, often as an
adaptive response to chronic irritation or stress. In smokers, the normal ciliated
columnar epithelium of the bronchi is replaced by tougher squamous epithelium,
which is more resistant to irritation but lacks the protective ciliary function,
increasing the risk for malignant transformation over time.
,Question 4: Which of the following best describes apoptosis?
A. Uncontrolled cell death due to injury
B. Programmed cell death that does not trigger inflammation
C. Cell death due to lack of oxygen
D. Cell death secondary to infection only
E. Cell swelling leading to lysis
Correct Answer: B. Programmed cell death that does not trigger
inflammation EXPERT RATIONALE: Apoptosis is a regulated, energy-dependent
process of programmed cell death that eliminates damaged or unnecessary cells
without provoking an inflammatory response, since the cell membrane remains
intact and cellular contents are not released into the surrounding tissue. This is in
contrast to necrosis, which is unregulated, often results from injury or ischemia,
and triggers inflammation due to the release of intracellular contents.
Question 5: A patient experiences a myocardial infarction. The dead cardiac
tissue undergoes liquefaction over time. Which type of necrosis is most
associated with ischemic injury in highly cellular organs like the brain, but
can be relevant here due to enzymatic digestion?
A. Coagulative necrosis
B. Liquefactive necrosis
C. Caseous necrosis
D. Fat necrosis
E. Gangrenous necrosis
Correct Answer: B. Liquefactive necrosis EXPERT RATIONALE: Liquefactive
necrosis occurs when dead cells are digested by enzymes, transforming the tissue
into a liquid, viscous mass. It is most classically associated with hypoxic injury in the
brain due to the high lipid content and lack of structural framework, but it can also
, occur in bacterial infections where enzymes from neutrophils digest tissue.
Coagulative necrosis, by contrast, is the hallmark of myocardial infarction itself,
where protein denaturation preserves the tissue architecture initially.
Question 6: Which type of necrosis is characteristically seen in myocardial
infarction, where the tissue architecture is initially preserved due to protein
denaturation?
A. Liquefactive necrosis
B. Caseous necrosis
C. Coagulative necrosis
D. Fibrinoid necrosis
E. Fat necrosis
Correct Answer: C. Coagulative necrosis EXPERT RATIONALE: Coagulative
necrosis occurs when ischemia denatures cellular proteins, including enzymes,
before the cell can be digested. This preserves the basic tissue architecture for
several days, which is characteristic of infarcted tissue in organs such as the heart
and kidney. Over time, dead cells are eventually removed by phagocytosis and
replaced with scar tissue.
Question 7: A patient with tuberculosis has a lung biopsy showing a cheese-
like, soft, granular area of necrosis. This describes which type of necrosis?
A. Coagulative necrosis
B. Liquefactive necrosis
C. Caseous necrosis
D. Fat necrosis
E. Gangrenous necrosis
