CORE DOMAINS
Cellular Adaptation, Injury, and Death
Inflammation and Immunity
Genetics and Genetic Disorders
Fluid, Electrolyte, and Acid-Base Balance

Renal and Urologic Pathophysiology
Gastrointestinal and Hepatobiliary Pathophysiology

INTRODUCTION
This comprehensive examination assesses the advanced pathophysiology
knowledge and clinical reasoning skills required of the graduate nursing
student at William Paterson University. It evaluates foundational
mechanisms of cellular adaptation, injury, inflammation, immunity, and
system-based pathophysiology across the lifespan. The examination
employs multiple-choice and case-based questions to simulate realistic
clinical encounters. Emphasis is placed on critical thinking, integration of
pathophysiologic mechanisms with clinical presentation, and the application
of evidence-based diagnostic reasoning. This assessment prepares
candidates for the rigor of advanced practice nursing certification and real-
world clinical practice.
SECTION ONE: QUESTIONS 1–100
1. Which of the following best defines pathophysiology?
A. The study of normal body function
B. The study of structural changes in disease
C. The study of the functional changes that occur in the body as a result of
,disease
D. The study of the cause of disease
C. The study of the functional changes that occur in the body as a
result of disease
RATIONALE: Pathophysiology focuses on the functional alterations in
cells, tissues, and organs that underlie disease processes, distinguishing it
from anatomy (structure) and physiology (normal function) .
2. Which term describes the cause or origin of a disease?
A. Pathogenesis
B. Etiology
C. Manifestation
D. Prognosis
B. Etiology
RATIONALE: Etiology refers to the causal factors of a disease,
including biological agents, physical forces, chemical agents, genetic
mutations, and nutritional imbalances .
3. A patient with hypertension develops left ventricular hypertrophy.
This is an example of which type of cellular adaptation?
A. Atrophy
B. Hyperplasia
C. Hypertrophy
D. Metaplasia
C. Hypertrophy
RATIONALE: Hypertrophy is an increase in cell size. In hypertension,
the left ventricle works against increased pressure (afterload), causing
cardiac myocytes to enlarge as an adaptive response to meet the
increased workload .
4. The hallmark of apoptosis is:
A. Cell swelling and lysis with inflammation
B. Caseous necrosis with granuloma formation
,C. Cell shrinkage, nuclear fragmentation, and formation of apoptotic bodies
without inflammation
D. Coagulative necrosis with preserved tissue architecture
C. Cell shrinkage, nuclear fragmentation, and formation of apoptotic
bodies without inflammation
RATIONALE: Apoptosis is programmed cell death characterized by cell
shrinkage, chromatin condensation, nuclear fragmentation, and formation
of apoptotic bodies that are phagocytosed without eliciting an inflammatory
response .
5. A patient with chronic kidney disease develops decreased muscle
mass. This is an example of which type of cellular adaptation?
A. Atrophy
B. Hypertrophy
C. Hyperplasia
D. Metaplasia
A. Atrophy
RATIONALE: Atrophy is a decrease in cell size and organ size resulting
from reduced workload, loss of innervation, diminished blood supply,
inadequate nutrition, or aging. In chronic kidney disease, decreased muscle
mass reflects atrophy due to metabolic derangements .
6. A patient with chronic gastroesophageal reflux disease develops
Barrett's esophagus. This is an example of which type of cellular
adaptation?
A. Atrophy
B. Hyperplasia
C. Hypertrophy
D. Metaplasia
D. Metaplasia
RATIONALE: Metaplasia is the reversible replacement of one
differentiated cell type with another. In Barrett's esophagus, the normal
, stratified squamous epithelium of the esophagus is replaced by columnar
epithelium resembling that of the intestine, in response to chronic acid
exposure .
7. The most common cause of cell injury leading to necrosis is:
A. Hypoxia/ischemia
B. Physical trauma
C. Chemical agents
D. Infectious agents
A. Hypoxia/ischemia
RATIONALE: Hypoxia or ischemia is the most common cause of cell
injury leading to necrosis. Reduced oxygen availability limits oxidative
phosphorylation, leading to ATP depletion and failure of the sodium-
potassium pump .
8. Which finding is most characteristic of apoptosis?
A. Cellular swelling with membrane rupture
B. Extensive inflammatory response
C. Cell shrinkage with formation of apoptotic bodies
D. Complete tissue liquefaction
C. Cell shrinkage with formation of apoptotic bodies
RATIONALE: Apoptosis is programmed cell death. Cells shrink,
chromatin condenses, and apoptotic bodies form without the marked
inflammation typically associated with necrosis .
9. A patient experiences prolonged tissue hypoxia. Which cellular
change is expected initially?
A. Increased oxidative phosphorylation
B. Increased anaerobic glycolysis
C. Increased ATP production
D. Increased mitochondrial oxygen consumption
B. Increased anaerobic glycolysis
RATIONALE: Reduced oxygen availability limits oxidative
