• The NR507 Advanced Pathophysiology Final Examination assesses the
competency of graduate-level nurse practitioner students enrolled 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 58-year-old male construction worker presents to the primary care clinic with
chronic fatigue and shortness of breath. He has a 30-year history of smoking two
packs per day, and his arterial blood gas reveals a carboxyhemoglobin level of 12%.
His cardiac myocytes show mitochondrial swelling and cristae disruption on
electron microscopy. The cellular injury pattern observed in this patient is best
classified as which type of adaptation or injury?
A. Hypoxic injury due to decreased oxygen-carrying capacity of hemoglobin
B. Ischemic injury due to reduced arterial blood flow to myocardial tissue
C. Chemical injury due to direct toxin-mediated destruction of cell membranes
D. Apoptotic injury due to programmed cell death triggered by carbon monoxide
RATIONALE: Carbon monoxide binds hemoglobin with 200 times the affinity of
oxygen, drastically reducing the oxygen-carrying capacity and causing hypoxic injury
to tissues, including mitochondrial swelling and cristae disruption. Ischemic injury
refers specifically to reduced blood flow rather than impaired oxygen transport.
Question 2
A 42-year-old female with a long history of poorly controlled hypertension is
admitted to the hospital with severe headache and visual disturbances.
Echocardiography reveals significant left ventricular wall thickening, and myocardial
biopsy shows enlarged cardiac myocytes with increased amounts of cytoplasmic
structural proteins. This myocardial change is best described as which cellular
adaptation?
,A. Hyperplasia resulting from increased number of cardiac myocytes under stress
B. Hypertrophy resulting from increased cell size due to chronic pressure
overload
C. Metaplasia resulting from replacement of one mature cell type by another
D. Dysplasia resulting from disorganized cellular proliferation in the myocardium
RATIONALE: Cardiac myocytes are terminally differentiated cells that cannot
undergo hyperplasia, so they respond to chronic pressure overload by increasing in
size through the addition of structural proteins, which defines hypertrophy.
Question 3
A 4-year-old boy is brought to the pediatric emergency department with a 2-day
history of high fever, severe sore throat, and swollen cervical lymph nodes. A
complete blood count reveals marked leukocytosis with atypical lymphocytes.
Which cellular adaptation or pathological process best explains the atypical
lymphocytes seen in this patient?
A. Hyperplasia of normal lymphocytes
B. Hypertrophy of lymphoid tissue
C. Reactive lymphoid hyperplasia with atypical features
D. Metaplasia of lymphoid cells
RATIONALE: In infectious mononucleosis and similar viral illnesses, lymphoid
tissue undergoes reactive hyperplasia with atypical lymphocytes. This is a benign,
reversible proliferation in response to infection.
Question 4
A pathologist examines a liver biopsy from a patient with chronic alcohol use
disorder. The hepatocytes contain large cytoplasmic lipid droplets that displace the
nucleus. This reversible change is an example of which cellular adaptation or injury
pattern?
A. Atrophy
B. Hypertrophy
, C. Steatosis (fatty change)
D. Necrosis
RATIONALE: Steatosis, or fatty change, is a reversible form of cell injury
characterized by accumulation of lipid vacuoles in the cytoplasm. It is commonly
seen in chronic alcohol use and metabolic disorders.
Question 5
A 68-year-old male with a 50-pack-year smoking history undergoes bronchoscopy
that reveals replacement of the normal ciliated columnar epithelium with stratified
squamous epithelium in the bronchi. This cellular change is best described as:
A. Hyperplasia
B. Metaplasia
C. Dysplasia
D. Anaplasia
RATIONALE: Metaplasia is the reversible substitution of one differentiated cell
type for another in response to chronic irritation. In this case, chronic smoke
exposure causes columnar epithelium to convert to squamous epithelium.
Question 6
A 30-year-old woman with a BRCA1 mutation undergoes breast biopsy showing
ductal epithelium with loss of polarity, nuclear pleomorphism, and increased mitotic
figures, but the myoepithelial layer remains intact. This finding is consistent with:
A. Hyperplasia
B. Metaplasia
C. Dysplasia
D. Carcinoma in situ
RATIONALE: Dysplasia is characterized by disordered growth with cytologic
atypia confined within the basement membrane. It represents a pre-neoplastic
change. Carcinoma in situ would involve malignant cells that have not invaded.
