Section 1: Cellular Function, Injury & Adaptation (Questions 1-25)
Q1: A Jersey College nursing student is caring for a patient with right-sided hemiplegia
following a stroke. The patient's right arm muscles have decreased in size due to lack of
use. Which cellular adaptation is this?
A. Hypertrophy
B. Hyperplasia
C. Atrophy [CORRECT]
D. Metaplasia
Correct Answer: C
Rationale: Atrophy is a decrease in cell size due to decreased workload, which aligns
with the Jersey College curriculum's definition of disuse atrophy following neurologic
injury; hypertrophy is an increase in size, hyperplasia is an increase in number, and
metaplasia is a change in cell type.
Q2: A patient is diagnosed with cardiomegaly secondary to chronic hypertension. The
left ventricular wall has thickened to compensate for increased afterload. What is the
primary mechanism of this adaptation?
A. Increased cell division
B. Increased cellular protein synthesis and organelles [CORRECT]
C. Replacement of dead cells with fibrous tissue
D. Conversion of one cell type to another
Correct Answer: B
Rationale: Hypertrophy, as emphasized in Jersey College pathophysiology case
studies, occurs via increased synthesis of cellular proteins and organelles (not cell
division) to adapt to increased stress, such as hypertension; the other options describe
hyperplasia, fibrosis, and metaplasia respectively.
Q3: A patient with a history of chronic GERD develops Barrett's esophagus. The normal
stratified squamous epithelium of the esophagus is replaced by intestinal columnar
epithelium. This is an example of:
A. Dysplasia
B. Metaplasia [CORRECT]
C. Hyperplasia
D. Anaplasia
Correct Answer: B
,Rationale: Metaplasia is the reversible replacement of one fully differentiated cell type
with another, often as an adaptive response to chronic irritation, a key Jersey College
curriculum concept for Barrett's esophagus; dysplasia is abnormal maturation,
hyperplasia is increased number, and anaplasia refers to undifferentiated tumor cells.
Q4: Which of the following cellular adaptations is considered a premalignant condition
characterized by deranged cell growth of a specific tissue?
A. Hyperplasia
B. Metaplasia
C. Dysplasia [CORRECT]
D. Atrophy
Correct Answer: C
Rationale: Jersey College emphasizes that dysplasia is characterized by abnormal
changes in cell size, shape, and organization that are strongly considered
precancerous, distinguishing it from reversible adaptations like hyperplasia and
metaplasia.
Q5: A patient presents with severe crushing chest pain. The myocardial cells in the
affected area experience a sudden, severe decrease in oxygen supply. What is the most
immediate consequence of this hypoxia at the cellular level?
A. Nuclear chromatin condensation
B. Depletion of ATP [CORRECT]
C. Rupture of the plasma membrane
D. Influx of calcium into the cell
Correct Answer: B
Rationale: According to Jersey College cellular injury protocols, hypoxia leads to
decreased oxidative phosphorylation, making ATP depletion the most immediate
consequence, whereas chromatin condensation (apoptosis/necrosis) and membrane
rupture occur later; calcium influx happens secondary to ATP depletion.
Q6: A patient suffers a crush injury to their lower extremity. When the tourniquet is
removed, the reperfusion of the tissue causes massive free radical generation. Which
enzyme system is primarily responsible for this?
A. Cyclooxygenase
B. Lipoxygenase
C. Xanthine oxidase [CORRECT]
D. Monoamine oxidase
Correct Answer: C
Rationale: Jersey College pathophysiology materials teach that ischemia-reperfusion
injury causes calcium accumulation that converts xanthine dehydrogenase to xanthine
,oxidase, which generates massive amounts of reactive oxygen species (ROS) when
oxygen is reintroduced.
Q7: A patient with a genetic deficiency in antioxidant enzymes (e.g., glutathione
peroxidase) is highly susceptible to cellular injury from lipid peroxidation. What are the
highly reactive molecules that cause this damage?
A. Reactive nitrogen species (RNS)
B. Reactive oxygen species (ROS) [CORRECT]
C. Complement proteins
D. Acute phase reactants
Correct Answer: B
Rationale: ROS, such as superoxide and hydroxyl radicals, cause lipid peroxidation
damaging cell membranes, a core Jersey College concept; RNS cause nitrosative
stress, while complement and acute phase reactants are part of the
immune/inflammatory response.
Q8: A patient with severe liver disease has impaired urea cycle function, leading to an
accumulation of ammonia in the blood. Ammonia is directly toxic to cells because it
combines with which ion?
A. Potassium
B. Calcium
C. Alpha-ketoglutarate [CORRECT]
D. Sodium
Correct Answer: C
Rationale: Jersey College curriculum highlights that ammonia combines with
alpha-ketoglutarate to form glutamine, which depletes alpha-ketoglutarate needed for
the Krebs cycle, severely impairing ATP production and causing cellular injury.
Q9: A patient is prescribed a chemotherapy drug that damages cellular DNA, triggering
programmed cell death. What is the morphologic hallmark of this type of cell death?
A. Cellular swelling and rupture
B. Cell shrinkage, chromatin condensation, and apoptotic bodies [CORRECT]
C. Inflammation and neutrophil infiltration
D. Caseous necrosis
Correct Answer: B
Rationale: Apoptosis is programmed, energy-dependent cell death characterized by cell
shrinkage, chromatin condensation, and formation of apoptotic bodies without
inflammation, aligning perfectly with Jersey College distinctions between physiologic
and pathologic death.
, Q10: A patient presents with a "cold abscess" in the lung. Biopsy reveals necrotic tissue
that appears as granular, cheese-like debris surrounded by macrophages. What type of
necrosis is this?
A. Liquefactive necrosis
B. Coagulative necrosis
C. Caseous necrosis [CORRECT]
D. Fat necrosis
Correct Answer: C
Rationale: Jersey College case studies on tuberculosis emphasize that caseous
necrosis has a gross appearance of clumped, cheese-like debris and is a classic
hallmark of granulomatous inflammation caused by mycobacteria.
Q11: A patient suffers an acute myocardial infarction. The necrotic area in the heart
maintains its structural outline for several days before being removed by inflammatory
cells. What type of necrosis is this?
A. Liquefactive necrosis
B. Coagulative necrosis [CORRECT]
C. Fat necrosis
D. Gangrenous necrosis
Correct Answer: B
Rationale: Coagulative necrosis, as taught in Jersey College cardiovascular modules,
occurs in ischemic injury to most solid organs (except the brain) where the tissue
architecture is preserved due to protein denaturation.
Q12: A patient with untreated acute bacterial meningitis develops brain abscesses. The
necrotic brain tissue is completely liquefied. What type of necrosis is occurring?
A. Coagulative necrosis
B. Liquefactive necrosis [CORRECT]
C. Caseous necrosis
D. Fat necrosis
Correct Answer: B
Rationale: Jersey College neurology pathophysiology explains that liquefactive necrosis
is characteristic of bacterial infections and brain infarcts, where hydrolytic enzymes
completely digest the dead cells into a liquid pus.
Q13: A patient with acute pancreatitis develops focal areas of fat necrosis in the
peripancreatic tissue. What is the mechanism of this specific necrosis?
A. Activation of lipases that hydrolyze fat into glycerol and fatty acids [CORRECT]
B. Occlusion of the pancreatic arteries
C. Direct viral cytotoxicity
D. Accumulation of beta-amyloid proteins
