Introduction
The NURS 5315 Advanced Pathophysiology Exams 1-5 evaluates a graduate nursing student's
comprehensive mastery of pathophysiological concepts across the lifespan. The exam assesses
knowledge of cellular mechanisms, genetic disorders, immune responses, fluid and electrolyte balance,
and disease processes affecting every major body system. Candidates must demonstrate competency in
analyzing etiology, pathogenesis, and clinical manifestations at the cellular and systems levels. The
multiple-choice format includes knowledge-based and scenario-driven questions emphasizing critical
thinking, evidence-based decision-making, and advanced practice nursing application.
SECTION ONE: QUESTIONS 1–100
1. A 55-year-old male with a 30-year history of smoking undergoes a bronchoscopy. Biopsy results show
abnormal cellular changes including variation in cell size and shape, increased nuclear-to-cytoplasmic
ratio, and loss of normal tissue organization. These changes are characteristic of:
A. Metaplasia
B. Dysplasia
C. Hyperplasia
D. Anaplasia
, Correct answer: B. Dysplasia
RATIONALE: Dysplasia is characterized by abnormal cellular changes including pleomorphism,
hyperchromatic nuclei, increased nuclear-to-cytoplasmic ratio, and disordered tissue organization .
2. A 62-year-old female presents with acute chest pain and elevated cardiac troponins. Cardiac
catheterization reveals a thrombotic occlusion of the left anterior descending artery. Within 24 hours,
the affected myocardial tissue appears pale and firm microscopically. This pattern of necrosis is best
described as:
A. Liquefactive necrosis
B. Caseous necrosis
C. Coagulative necrosis
D. Fat necrosis
Correct answer: C. Coagulative necrosis
RATIONALE: Coagulative necrosis is characteristic of ischemic injury in most tissues except the brain,
preserving tissue architecture due to protein denaturation while inhibiting enzymatic digestion .
3. A patient with chronic hepatitis C develops cirrhosis. The liver demonstrates shrunken, nodular
appearance with bands of fibrous tissue. Which cellular adaptation process primarily contributes to the
nodular regeneration observed?
A. Hypertrophy
B. Hyperplasia
C. Metaplasia
D. Atrophy
Correct answer: B. Hyperplasia
RATIONALE: Hyperplasia is the increase in cell number that drives nodular regeneration in cirrhosis,
as surviving hepatocytes proliferate in response to chronic injury and fibrosis .
4. A 45-year-old woman presents with progressive dyspnea. Lung biopsy reveals type II pneumocyte
hyperplasia and interstitial thickening with fibroblast foci. Which pathophysiological mechanism best
explains the progressive fibrosis in this pattern of lung injury?
A. Impaired apoptosis of fibroblasts with continued collagen deposition
B. Excessive acute inflammatory cell infiltration
C. Primary endothelial cell proliferation
D. Defective phagocytosis by alveolar macrophages
Correct answer: A. Impaired apoptosis of fibroblasts with continued collagen deposition
RATIONALE: Progressive pulmonary fibrosis involves dysregulated wound healing with impaired
apoptosis of activated fibroblasts, leading to continued extracellular matrix deposition and scar
formation .
5. A newborn is diagnosed with trisomy 21. Which pathophysiological mechanism is responsible for the
characteristic facial features and intellectual disability in this chromosomal disorder?
, A. Single gene mutation affecting neural development
B. Nondisjunction during meiosis resulting in three copies of chromosome 21
C. Mitochondrial DNA mutation
D. Imprinting defect on chromosome 15
Correct answer: B. Nondisjunction during meiosis resulting in three copies of chromosome 21
RATIONALE: Down syndrome results from nondisjunction during meiosis, producing three copies of
chromosome 21 and gene dosage effects disrupting normal development .
6. A 28-year-old male develops fever and swollen lymph nodes after a bacterial infection. Biopsy shows
neutrophilic infiltration, vascular dilation, and edema. Which vascular event initiates this acute
inflammatory response?
A. Vasoconstriction followed by persistent vessel narrowing
B. Immediate prolonged vasodilation
C. Transient vasoconstriction followed by vasodilation and increased vascular permeability
D. Permanent endothelial cell destruction
Correct answer: C. Transient vasoconstriction followed by vasodilation and increased vascular
permeability
RATIONALE: Acute inflammation begins with transient vasoconstriction, followed by vasodilation
and increased vascular permeability that allows plasma proteins and leukocytes to enter the tissue .
7. A 24-year-old male sustains a severe crushing injury to his right lower extremity during an industrial
accident. Within 36 hours, he develops profound muscle weakness, dark tea-colored urine, and an acute
spike in serum creatinine. Pathophysiologically, what cellular mechanism directly explains the
development of his acute kidney injury?
A. Excessive circulating cellular sodium blocks the glomerular filtration membrane
B. Myocyte rupture releases massive amounts of intracellular myoglobin into the bloodstream, which
precipitates in the renal tubules
C. Apoptotic signaling forces the rapid degradation of functional renal cell nuclei
D. Intracellular calcium storage failure causes local renal arteries to spasm persistently
Correct answer: B. Myocyte rupture releases massive amounts of intracellular myoglobin into the
bloodstream, which precipitates in the renal tubules
RATIONALE: Rhabdomyolysis causes plasma membrane failure, releasing myoglobin that is filtered
by the glomerulus and causes direct toxic acute tubular necrosis and cast obstruction .
8. During an autopsy of a patient who suffered a massive ischemic stroke, the pathologist observes that
the dead brain tissue has transformed into a soft, liquid mass containing fluid-filled cavities. Which type
of cellular necrosis is uniquely characteristic of this organ pathology?
A. Coagulative necrosis
B. Caseous necrosis
C. Liquefactive necrosis
D. Fat necrosis
