NSG 3280 EXAM 1 PRACTICE EXAM:
PATHOPHYSIOLOGY FOR NURSES I
(2026/2027) QUESTIONS AND VERIFIED
CORRECT ANSWERS
.
Introduction
Pathophysiology for Nurses I examines the physiological mechanisms behind disease, how
normal body functions become disrupted, and how these changes produce the signs and
symptoms observed in clinical practice. This NSG 3280 Exam 1 practice resource is intended for
nursing students preparing to apply foundational pathophysiology concepts to patient
assessment, clinical reasoning, and nursing care.
Understanding pathophysiology is essential because effective nursing decisions depend on
recognizing why a patient’s condition is changing, identifying early signs of deterioration,
interpreting laboratory findings, and anticipating complications. Rather than relying on
memorization alone, students need to connect cellular injury, inflammation, fluid and electrolyte
imbalances, acid–base disturbances, genetic mechanisms, and altered organ function to realistic
clinical scenarios.
This practice bank contains challenging, application-level multiple-choice questions, each with
four options and a detailed rationale explaining the correct answer and why the alternatives are
less appropriate. Use the questions to identify knowledge gaps, review the underlying
mechanisms, and practice distinguishing similar clinical presentations. Compare the topics with
your instructor’s Exam 1 learning objectives and assigned materials, since the precise scope and
weighting of NSG 3280 may vary by institution and course section.

QUESTIONS 1–100
Section 1: Cellular adaptation and injury
Q1
A patient with long-standing hypertension develops thickening of the left ventricular wall.
Which cellular mechanism most directly explains this change?
A) Increased cardiomyocyte number through routine cell division B) Increased size of existing
cardiomyocytes in response to sustained workload C) Replacement of cardiomyocytes with
mature skeletal muscle cells D) Programmed destruction of cardiomyocytes followed by
compensatory shrinkage
Rationale: B is correct because adult cardiac muscle cells respond to chronic pressure overload
primarily through hypertrophy, increasing cell size and protein synthesis. A is incorrect because
mature cardiomyocytes have limited proliferative capacity. C describes an abnormal cell-type
replacement that does not explain hypertensive remodeling. D describes cell loss rather than the
thickened ventricular wall.
Q2
,3|Page
A patient’s lower-limb muscle becomes smaller after six weeks in a cast. Which mechanism best
explains the change?
A) Hyperplasia caused by increased mechanical stimulation B) Metaplasia caused by altered
tissue differentiation C) Atrophy resulting from reduced mechanical use and decreased protein
synthesis D) Dysplasia caused by uncontrolled cellular maturation
Rationale: C is correct because immobilization reduces mechanical stimulation, promoting
protein breakdown and decreasing muscle fiber size. A involves increased cell number and is
inconsistent with disuse. B involves replacement by another mature cell type. D describes
disordered cellular growth and maturation, not the expected response to immobilization.
Q3
A smoker develops replacement of normal ciliated bronchial columnar epithelium with stratified
squamous epithelium. Which interpretation is most accurate?
A) Irreversible malignant transformation has necessarily occurred B) Metaplasia has occurred as
an adaptive response to chronic irritation C) Normal epithelial apoptosis has produced an
increase in cell size D) Hyperplasia has converted mature epithelial cells into connective tissue
Rationale: B is correct because chronic irritation can trigger replacement of one mature epithelial
type with another better able to tolerate the stress. This adaptation may impair mucociliary
clearance and can increase cancer risk if harmful exposure continues. A is incorrect because
metaplasia is not itself cancer. C confuses apoptosis with cellular adaptation. D incorrectly
describes hyperplasia and connective-tissue formation.
Q4
A patient experiences severe coronary artery occlusion. Cardiac cells develop swelling,
membrane damage, and leakage of intracellular enzymes. Which process is most likely
occurring?
A) Physiological hypertrophy B) Reversible adaptation without membrane injury C)
Programmed cell death without inflammation in every affected cell D) Irreversible ischemic cell
injury progressing toward necrosis
Rationale: D is correct because severe, sustained ischemia depletes ATP and disrupts membrane
integrity, allowing intracellular contents to escape. A is an adaptive increase in cell size, not
acute ischemic destruction. B is inconsistent with membrane damage and enzyme leakage. C
describes a generalized feature of apoptosis, which typically preserves membrane integrity until
late stages.
Q5
, 4|Page
A laboratory researcher observes controlled cell shrinkage, chromatin condensation, and
fragmentation into membrane-bound bodies without substantial surrounding inflammation.
Which process is demonstrated?
A) Apoptosis B) Liquefactive necrosis C) Coagulative necrosis D) Fat necrosis
Rationale: A is correct because apoptosis is regulated cell death characterized by cell shrinkage,
chromatin condensation, and membrane-bound apoptotic bodies. B is associated with enzymatic
digestion, classically in cerebral infarction. C commonly occurs in ischemic solid organs other
than the brain. D involves enzymatic fat destruction, often associated with pancreatic injury.
Q6
A patient has a cerebral infarction. The damaged area undergoes enzymatic digestion and
eventually becomes a cavity. Which type of necrosis is characteristic of this injury?
A) Coagulative necrosis B) Caseous necrosis C) Liquefactive necrosis D) Fibrinoid necrosis
Rationale: C is correct because enzymatic digestion predominates in brain infarction, producing
liquefactive necrosis. A typically preserves tissue architecture initially in ischemic solid organs.
B is classically associated with certain granulomatous infections. D is associated with immune-
mediated or severe vascular injury.
Q7
A patient’s kidney sustains prolonged ischemia. Microscopy initially shows preserved tissue
architecture despite loss of viable cells. Which process best fits this finding?
A) Liquefactive necrosis B) Coagulative necrosis C) Fat necrosis D) Physiological apoptosis
only
Rationale: B is correct because ischemia in most solid organs produces coagulative necrosis, in
which protein denaturation initially preserves tissue outlines. A is characteristic of cerebral
infarction and some abscesses. C primarily involves adipose tissue. D cannot explain the
characteristic pattern of widespread ischemic necrosis.
Q8
A patient with chronic pressure on the skin develops thickening of the epidermis. Which process
most directly increases the number of epithelial cells?
A) Hypertrophy B) Atrophy C) Metaplasia D) Hyperplasia
Rationale: D is correct because hyperplasia increases cell number through proliferation. A
increases cell size rather than cell number. B decreases cell size or tissue mass. C changes the
differentiated cell type and does not primarily mean an increased number of cells.
