Aligned with Rasmussen University NUR 2063 Course Syllabus, NCLEX-RN Pathophysiology Standards, and Essentials of
Pathophysiology Competencies (2026/2027 Edition). 150 Questions - 12 Sections.
Section 1: Cellular Injury, Adaptation, & Death
Q1: A 68-year-old male with long-standing hypertension presents with an echocardiogram
demonstrating increased left ventricular wall thickness. The cardiologist explains this represents an
adaptive response to chronically elevated afterload. Which cellular adaptation mechanism BEST
explains this finding?
A. Atrophy due to decreased workload
B. Hypertrophy from increased workload *[CORRECT]*
C. Hyperplasia from hormonal stimulation
D. Metaplasia from chronic irritation
Correct Answer: B
Rationale: Hypertrophy is an increase in cell size in response to increased workload, classically seen in cardiac
myocytes adapting to elevated afterload in hypertension. Atrophy is the opposite (decrease in cell size), hyperplasia is
an increase in cell number (not applicable to permanently divided cells like cardiac myocytes), and metaplasia is
reversible replacement of one adult cell type with another.
Q2: A 55-year-old chronic smoker undergoes bronchoscopy with biopsy of the bronchial epithelium.
Pathology reveals replacement of the normal ciliated pseudostratified columnar epithelium with
stratified squamous epithelium. This cellular adaptation is BEST classified as:
A. Dysplasia
B. Metaplasia *[CORRECT]*
C. Anaplasia
D. Hyperplasia
Correct Answer: B
Rationale: Metaplasia is the reversible replacement of one differentiated adult cell type with another, often as an
adaptive substitution to chronic irritation (e.g., squamous metaplasia in bronchi of smokers). Dysplasia indicates
disordered growth with atypical cells (a pre-neoplastic change), anaplasia refers to lack of differentiation in cancer cells,
and hyperplasia is increased cell number. Metaplasia is initially protective but reduces mucus clearance, predisposing to
infection and malignancy.
Q3: A pathologist evaluating a renal biopsy notes cells exhibiting irreversible injury. Which finding is
MOST indicative of irreversible cellular injury and impending cell death?
A. Cellular swelling and steatosis
B. Mitochondrial swelling and dispersion of ribosomes

,NUR 2063 - Essentials of Pathophysiology - Final Exam Page 2
C. Severe depletion of intracellular glycogen
D. Rupture of the lysosomal and plasma membranes *[CORRECT]*
Correct Answer: D
Rationale: Rupture of lysosomal and plasma membranes is a hallmark of irreversible injury because it releases
hydrolytic enzymes into the cytoplasm and triggers uncontrolled digestion, inflammation, and cell death. Cellular
swelling, mitochondrial swelling, ribosomal dispersion, and glycogen depletion are features of reversible injury that
may progress but are not, by themselves, irreversible markers. The key event distinguishing reversible from irreversible
injury is profound membrane damage.
Q4: A 45-year-old female presents with a cold, pulseless, blue-tinged lower extremity following 6 hours
of femoral artery thrombosis. The affected tissue undergoes infarction. Which type of necrosis is
MOST expected in this ischemic tissue?
A. Liquefactive necrosis
B. Coagulative necrosis *[CORRECT]*
C. Caseous necrosis
D. Fat necrosis
Correct Answer: B
Rationale: Coagulative necrosis is the typical pattern of cell death in solid organs (heart, kidney, spleen) following
ischemia, in which cellular architecture is preserved for some time because denatured proteins retain structure while
enzymatic digestion is impaired. Liquefactive necrosis occurs in the brain (ischemic stroke) or with bacterial infection
(abscess). Caseous necrosis is associated with tuberculosis, and fat necrosis occurs in pancreatic lipase exposure to
adipose tissue.
Q5: A 70-year-old female with a femoral fracture develops a fat embolism and dies 48 hours later.
Autopsy reveals chalky-white, soap-like deposits in subcutaneous fat of the lower limbs. This
appearance is pathognomonic for which type of necrosis?
A. Caseous necrosis
B. Liquefactive necrosis
C. Fat necrosis *[CORRECT]*
D. Fibrinoid necrosis
Correct Answer: C
Rationale: Fat necrosis occurs when lipase enzymes (often pancreatic, but also from inflammatory cells) digest
triglycerides into free fatty acids that combine with calcium to form soap-like, chalky-white deposits. Caseous necrosis
has a cheese-like appearance in TB, liquefactive necrosis results in liquid pus, and fibrinoid necrosis involves immune
complex deposition in vessel walls (not grossly visible as chalky deposits).
Q6: An infant born with tracheoesophageal fistula undergoes surgical correction. During development,
the cells destined to die to allow separation of trachea and esophagus undergo a programmed process
characterized by chromatin condensation, cell shrinkage, and apoptotic body formation. This process
is BEST described as:
A. Coagulative necrosis
B. Apoptosis *[CORRECT]*
C. Autophagy
D. Liquefactive necrosis

,NUR 2063 - Essentials of Pathophysiology - Final Exam Page 3
Correct Answer: B
Rationale: Apoptosis is programmed cell death, characterized by cell shrinkage, chromatin condensation, membrane
blebbing, and formation of apoptotic bodies that are phagocytosed without significant inflammation. It is essential in
development, tissue homeostasis, and immune regulation. Unlike necrosis, apoptosis is energy-dependent, highly
regulated, and does not elicit an inflammatory response, distinguishing it from coagulative or liquefactive necrosis.
Q7: A 28-year-old male rescuing hikers at high altitude (5500 m) develops confusion, ataxia, and
decreased consciousness. Cerebral cells are exposed to chronic hypoxia. In the pathophysiology of
hypoxic injury, which cellular event occurs FIRST as oxygen tension declines?
A. Decreased ATP production leading to Na+/K+ pump failure *[CORRECT]*
B. Activation of lysosomal enzymes and membrane rupture
C. Free radical generation in mitochondria
D. Calcium influx triggering apoptosis
Correct Answer: A
Rationale: Hypoxia first decreases oxidative phosphorylation in mitochondria, reducing ATP synthesis. With
insufficient ATP, the Na+/K+-ATPase pump fails, allowing sodium (and water) to enter the cell causing cellular
swelling, potassium to leave, and calcium to accumulate intracellularly. Subsequent events—free radical formation,
lysosomal enzyme activation, and apoptosis—follow this initial ATP depletion, making energy failure the earliest
pathophysiologic event.
Q8: A 50-year-old welder presents with chronic copper exposure. Laboratory findings suggest hepatic
injury caused by reactive oxygen species. Which statement BEST describes the role of free radicals in
cellular injury?
A. They enhance mitochondrial oxidative phosphorylation
B. They are stable molecules that improve DNA repair
C. They damage lipids, proteins, and DNA through oxidative reactions *[CORRECT]*
D. They activate protective antioxidant pathways only
Correct Answer: C
Rationale: Free radicals are highly reactive, unstable molecules with unpaired electrons that damage lipids
(peroxidation of membrane phospholipids), proteins (cross-linking, denaturation), and DNA (strand breaks, base
modifications), leading to cellular injury. They do not enhance oxidative phosphorylation or DNA repair; rather, they
impair these processes. Antioxidant defenses (superoxide dismutase, catalase, glutathione) help neutralize them, but
excess production overwhelms these defenses.
Q9: A 60-year-old male with Barrett esophagus undergoes endoscopic surveillance. Biopsy reveals cells
with disordered architecture, increased nuclear-to-cytoplasmic ratio, and hyperchromatic nuclei, but
no invasion through the basement membrane. This finding is classified as:
A. Metaplasia only
B. Mild dysplasia *[CORRECT]*
C. Carcinoma in situ
D. Invasive adenocarcinoma
Correct Answer: B
Rationale: Dysplasia is disordered cellular proliferation with atypical features (pleomorphism, hyperchromatic nuclei,
increased mitoses) but no breach of the basement membrane. In Barrett esophagus, metaplasia (columnar replacement of
squamous epithelium) may progress to dysplasia, which is a pre-neoplastic change. Carcinoma in situ is full-thickness

dysplasia without invasion, and invasive adenocarcinoma penetrates the basement membrane. The biopsy described
shows dysplasia.
Q10: A 75-year-old male has progressive memory decline and brain imaging reveals generalized
cortical atrophy. Cellular aging involves telomere shortening, oxidative damage, and decreased
regenerative capacity. Which cellular process is most directly associated with replicative senescence in
aging cells?
A. Progressive telomere shortening with each cell division *[CORRECT]*
B. Decreased lysosomal activity
C. Increased proteasomal degradation
D. Hyperactivation of apoptotic pathways
Correct Answer: A
Rationale: Telomeres are repetitive DNA sequences at chromosome ends that shorten with each cell division because
DNA polymerase cannot fully replicate the lagging strand. When telomeres reach a critical length, cells enter replicative
senescence (Hayflick limit). This telomere shortening is a hallmark of cellular aging. Decreased lysosomal activity,
altered proteasomal function, and apoptosis contribute to aging but are not the primary drivers of replicative senescence.
Q11: A 40-year-old female with severe burns over 60% of her body develops acute tubular necrosis.
The renal tubular cells demonstrate autophagic vacuoles containing damaged organelles. Which
statement BEST describes autophagy?
A. Random cell death through membrane rupture
B. Programmed cell death via caspase activation
C. Self-digestion of damaged organelles via lysosomes *[CORRECT]*
D. Bystander injury due to complement activation
Correct Answer: C
Rationale: Autophagy is a regulated self-catabolic process in which damaged organelles and misfolded proteins are
sequestered in double-membrane autophagosomes and delivered to lysosomes for digestion. It serves as a survival
mechanism under nutrient stress and quality control, but excessive or dysregulated autophagy can contribute to cell
death. It is distinct from apoptosis (caspase-mediated programmed death) and necrosis (membrane rupture with
inflammation).
Q12: A 35-year-old IV drug user develops infective endocarditis and dies of acute myocardial
infarction. Histologic examination of the infarcted myocardium at 24 hours shows increased
eosinophilia, loss of cross-striations, and coagulative necrosis. Which mechanism BEST explains this
histologic appearance?
A. Protein denaturation preserving cell outline *[CORRECT]*
B. Lipid breakdown forming soap
C. Cytotoxic T-cell mediated apoptosis
D. Bacterial enzymatic digestion of tissue
Correct Answer: A
Rationale: Coagulative necrosis in myocardial infarction results from protein denaturation. Denatured structural
proteins and enzymes preserve the cell outline and tissue architecture, while loss of cross-striations and increased
eosinophilia reflect protein changes. This distinguishes coagulative necrosis from liquefactive necrosis (enzymatic
digestion producing liquid), caseous (cheesy granuloma in TB), or fat necrosis (lipase acting on fat).
