Introduction
The NR 507 Final Examination assesses the competency of
graduate-level nurse practitioner students enrolled in Advanced
Pathophysiology at Chamberlain University. This comprehensive
,assessment evaluates knowledge across critical domains including
cellular adaptation, genetics, inflammation, immunity, and the
pathophysiology of major body systems. The examination
employs multiple-choice and scenario-based questions that
require candidates to demonstrate applied decision-making skills
essential for advanced nursing practice. Emphasis is placed on
disease mechanisms, clinical manifestations, and evidence-based
practice concepts. Successful completion validates the candidate's
readiness to apply pathophysiological principles in clinical
practice.
SECTION ONE: QUESTIONS 1–100
Question 1
A 68-year-old male with chronic GERD undergoes endoscopy
revealing intestinal-type columnar epithelium replacing the
normal squamous epithelium in the distal esophagus. This cellular
adaptation is BEST described as:
A. Hyperplasia
B. Metaplasia
C. Dysplasia
D. Anaplasia
B. Metaplasia
RATIONALE: Metaplasia is the reversible replacement of one
differentiated cell type with another, often an adaptive
substitution of cells sensitive to stress with cells better able to
withstand the adverse environment. In Barrett esophagus,
chronic acid exposure causes squamous epithelium to be replaced
by intestinal-type columnar epithelium.
Question 2
A patient's heart muscle increases in size due to chronic
hypertension. This cellular adaptation is called:
,A. Hyperplasia
B. Hypertrophy
C. Atrophy
D. Metaplasia
B. Hypertrophy
RATIONALE: Hypertrophy is an increase in cell SIZE, occurring
in tissues like cardiac and skeletal muscle composed of cells that
cannot divide. The increased workload from chronic hypertension
forces myocardial cells to enlarge to generate greater contractile
force.
Question 3
A pathologist examining a tissue specimen notes cell swelling,
vacuolation, and nuclear changes including pyknosis. These
findings are MOST consistent with:
A. Apoptosis
B. Reversible cell injury
C. Necrosis
D. Metaplasia
B. Reversible cell injury
RATIONALE: Cellular swelling (hydropic change) and
vacuolation are hallmarks of reversible cell injury - early
ischemic/hypoxic changes that can resolve if oxygenation is
restored. Necrosis is characterized by cell membrane rupture and
inflammation.
Question 4
Which of the following BEST distinguishes apoptosis from
necrosis?
A. Apoptosis involves cell swelling; necrosis involves cell
shrinkage
, B. Apoptosis is programmed cell death requiring ATP, with cell
shrinkage and no inflammation
C. Apoptosis triggers inflammation; necrosis does not
D. Apoptosis is a passive process; necrosis is active
B. Apoptosis is programmed cell death requiring ATP, with cell
shrinkage and no inflammation
RATIONALE: Apoptosis is energy-dependent, programmed cell
death characterized by cell shrinkage, fragmentation, and
phagocytosis by macrophages without initiating inflammation.
Necrosis causes swelling, rupture, and inflammation.
Question 5
A cell lacks the enzyme to break down sphingolipids. This results
in the accumulation of these substances within the cell. What is
this cellular process called?
A. Metaplasia
B. Intracellular accumulation
C. Apoptosis
D. Calcification
B. Intracellular accumulation
RATIONALE: The failure of enzymatic degradation leads to the
intracellular accumulation of substances, such as lipids, causing
conditions like Tay-Sachs disease.
Question 6
A patient has a prolonged blockage of the right coronary artery.
Which cellular change is most likely to occur in the myocardial
cells supplied by this artery?
A. Cellular atrophy
B. Cellular hypertrophy
