NR507 FINAL EXAM STUDY GUIDE 2026-2027| Advanced Pathophysiology |
Chamberlain University | Weeks 5
Preparing for the NR507 Advanced Pathophysiology final exam requires rigorous
practice and a deep understanding of complex disease mechanisms across
multiple body systems. This exclusive guide provides 300 unique, zero-repetition
questions that perfectly mirror the Weeks 5–8 exam format, including clinical
scenarios and mechanism-based reasoning. Master every critical concept with
verified answers and in-depth rationales to guarantee your success and secure
your A+ on test day.
SECTION 1: CELLULAR ADAPTATION, INJURY, AND DEATH (Q1–Q30)
1. A 68-year-old male with chronic hypertension develops increased left
ventricular wall thickness without chamber dilation. Which cellular
adaptation is primarily responsible?
A. Hyperplasia of cardiac myocytes
B. Hypertrophy of cardiac myocytes
C. Metaplasia of cardiac tissue
D. Atrophy of ventricular myocardium
Answer: B. Hypertrophy of cardiac myocytes
Explanation: Chronic pressure overload stimulates an increase in individual
myocyte size because cardiac myocytes are terminally differentiated and
cannot undergo hyperplasia.
,2. During acute myocardial infarction, irreversibly injured myocardium
shows membrane rupture, mitochondrial swelling, and calcium influx. Which
form of cell death is primarily occurring?
A. Apoptosis with orderly DNA fragmentation
B. Autophagy with lysosomal recycling
C. Necrosis with inflammatory sequelae
D. Senescence with permanent cell-cycle arrest
Answer: C. Necrosis with inflammatory sequelae
Explanation: Ischemic necrosis involves loss of membrane integrity,
organelle swelling, and inflammation, unlike energy-dependent apoptosis.
3. A patient with chronic GERD develops replacement of esophageal
squamous epithelium with columnar epithelium. This is best classified as:
A. Metaplasia driven by chronic injury
B. Hyperplasia of residual squamous cells
C. Dysplasia with disordered maturation
D. Neoplastic transformation to adenocarcinoma
Answer: A. Metaplasia driven by chronic injury
Explanation: Barrett esophagus is metaplasia—a reversible replacement of
one mature cell type by another better suited to chronic acid exposure.
4. A cervical biopsy shows abnormal cell size, shape, and organization, but
the basement membrane remains intact. This finding is most consistent
with:
A. Metaplasia
B. Hyperplasia
C. Dysplasia
D. Anaplasia
Answer: C. Dysplasia
Explanation: Dysplasia is disorganized growth with abnormal morphology
and loss of polarity, but the basement membrane remains intact.
,5. Which type of cell death is energy-dependent, non-inflammatory, and
characterized by cell shrinkage and nuclear fragmentation?
A. Necrosis
B. Apoptosis
C. Autophagy
D. Pyroptosis
Answer: B. Apoptosis
Explanation: Apoptosis is programmed cell death that does not incite
inflammation and features cell shrinkage and nuclear
condensation/fragmentation.
6. A cell that has lost specialized features and resembles a primitive cell is
described as:
A. Dysplastic
B. Metaplastic
C. Anaplastic
D. Hyperplastic
Answer: C. Anaplastic
Explanation: Anaplasia is lack of differentiation, a hallmark of malignant
tumors.
7. Which pigment accumulates after free radical–mediated lipid
peroxidation and is associated with aging?
A. Bilirubin
B. Lipofuscin
C. Melanin
D. Hemosiderin
Answer: B. Lipofuscin
Explanation: Lipofuscin is a "wear-and-tear" pigment formed from oxidized
lipids and proteins.
, 8. A 70-year-old male with chronic bronchitis has increased goblet cells
and submucosal glands. This adaptation is:
A. Hypertrophy
B. Hyperplasia
C. Metaplasia
D. Dysplasia
Answer: B. Hyperplasia
Explanation: Chronic irritation stimulates an increase in the number of
mucus-secreting cells (hyperplasia).
9. What is the single most common cause of cellular injury?
A. Oxidative stress
B. Hypoxic injury
C. Chemical exposure
D. Mechanical trauma
Answer: B. Hypoxic injury
Explanation: Hypoxic injury, due to inadequate oxygen supply, is the most
common cause of cellular injury, leading to impaired ATP production and
cell dysfunction.
10. Which mechanism most directly explains cellular swelling during
reversible injury?
A. Increased ATP production
B. Failure of the Na⁺/K⁺-ATPase pump
C. Enhanced protein synthesis
D. Activation of apoptosis
Answer: B. Failure of the Na⁺/K⁺-ATPase pump
Explanation: ATP depletion causes pump failure, allowing sodium and water
to enter the cell, producing swelling.
