NR 507 Advanced Pathophysiology Week 8 Final Exam
Chamberlain University | Academic Year 2026–2027
200-Question Comprehensive Practice Examination with Answers and Rationales
Description:
This comprehensive practice examination assesses advanced pathophysiology
concepts through multiple-choice questions emphasizing cellular mechanisms,
inflammation and immunity, genetics, hematologic disorders, cardiovascular
disease, pulmonary disease, renal and urologic disorders, neurologic disease,
endocrine disorders, gastrointestinal/hepatic disease, musculoskeletal disorders,
and multisystem pathophysiology. The examination contains 200 original questions
with four answer choices, one best answer, and mechanism-focused rationales.
Question distribution:
• Basic recall: 60 questions (30%)
• Application: 100 questions (50%)
• Analysis/critical thinking: 40 questions (20%)
• Total: 200 questions

SECTION 1 — CELLULAR BIOLOGY, INJURY, GENETICS & NEOPLASIA
Questions 1–20
Q1 — Basic Recall
Which cellular adaptation is characterized by an increase in cell size rather than an increase in
cell number?
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
Correct answer: B. Hypertrophy
Rationale: Hypertrophy results from enlargement of individual cells, usually because of
increased protein synthesis and organelle production. Hyperplasia instead involves an increased
number of cells.
Q2 — Basic Recall
Which cellular adaptation involves replacement of one mature differentiated cell type with
another mature differentiated cell type?
A. Atrophy
B. Hypertrophy
C. Metaplasia
D. Anaplasia
Correct answer: C. Metaplasia
Rationale: Metaplasia is a potentially reversible adaptation in which one differentiated cell type
is replaced by another better suited to the environmental stress. Anaplasia refers to loss of
cellular differentiation associated with malignancy.
Q3 — Basic Recall
,Which intracellular organelle is primarily responsible for ATP production through oxidative
phosphorylation?
A. Lysosome
B. Golgi apparatus
C. Mitochondrion
D. Ribosome
Correct answer: C. Mitochondrion
Rationale: Mitochondria generate most cellular ATP through oxidative phosphorylation.
Lysosomes digest cellular material, while ribosomes synthesize proteins.
Q4 — Application
A patient with chronic uncontrolled hypertension develops thickening of the left ventricular wall.
Which cellular response best explains this finding?
A. Hyperplasia of cardiomyocytes
B. Hypertrophy of cardiomyocytes
C. Metaplasia of cardiac muscle
D. Atrophy caused by increased workload
Correct answer: B. Hypertrophy of cardiomyocytes
Rationale: Chronic pressure overload increases the workload imposed on cardiomyocytes,
causing them to enlarge and synthesize additional contractile proteins. Mature cardiac muscle
cells have limited capacity for proliferative hyperplasia.
Q5 — Application
A patient experiences prolonged tissue hypoxia after severe blood loss. Which cellular change is
most likely to occur first?
A. Increased oxidative phosphorylation
B. Decreased ATP production
C. Increased mitochondrial activity
D. Increased protein synthesis
Correct answer: B. Decreased ATP production
Rationale: Oxygen deprivation impairs mitochondrial oxidative phosphorylation, producing an
early decline in ATP. Reduced ATP disrupts ion pumps and cellular homeostasis and can progress
to irreversible injury if prolonged.
Q6 — Basic Recall
Which type of necrosis is classically associated with myocardial infarction?
, A. Coagulative
B. Liquefactive
C. Caseous
D. Fat
Correct answer: A. Coagulative
Rationale: Ischemic injury in most solid organs produces coagulative necrosis, including
myocardial infarction. Liquefactive necrosis is more characteristic of cerebral infarction and
abscess formation.
Q7 — Application
A patient develops acute pancreatitis with extensive destruction of pancreatic tissue. Which
mechanism contributes to the resulting fat necrosis?
A. Activation of pancreatic lipase
B. Deposition of immune complexes
C. Denaturation of nuclear DNA
D. Reduced lysosomal enzyme activity
Correct answer: A. Activation of pancreatic lipase
Rationale: Pancreatic lipase hydrolyzes triglycerides, releasing fatty acids that combine with
calcium and produce saponification. This process produces the characteristic fat necrosis
associated with pancreatic injury.
Q8 — Analysis
A patient with prolonged ischemia develops cellular swelling, membrane disruption, and leakage
of intracellular enzymes. Which finding most strongly indicates that the injury has progressed
from reversible to irreversible cellular damage?
A. Mild cellular swelling
B. Fatty change
C. Severe membrane disruption
D. Temporary reduction in ATP
Correct answer: C. Severe membrane disruption
Rationale: Severe plasma and mitochondrial membrane damage is a major indicator of
irreversible cellular injury. Mild swelling and temporary ATP reduction may still be reversible if
the underlying insult is removed.
Q9 — Basic Recall
Which mechanism is most directly responsible for apoptosis?
