Introduction
The NR507 Advanced Pathophysiology Final Examination evaluates the graduate
nursing student's mastery of complex disease mechanisms across body systems.
The assessment measures understanding of cellular alterations, genetic influences,
inflammatory and immune responses, and the pathophysiologic basis of clinical
manifestations. Content emphasizes critical thinking and application of
,pathophysiologic principles to clinical scenarios encountered in advanced nursing
practice. This comprehensive test bank challenges the candidate to analyze disease
processes at the cellular and systemic levels, interpret diagnostic findings, and
predict clinical consequences of pathophysiologic alterations, preparing the
advanced practice nurse for evidence-based clinical decision-making.
SECTION ONE: QUESTIONS 1–200
1. A nurse is reviewing the process of cellular adaptation. Which type of
adaptation involves an increase in the number of cells in an organ or tissue?
A. Hypertrophy
B. Hyperplasia
C. Atrophy
D. Metaplasia
B. Hyperplasia
RATIONALE: Hyperplasia is an increase in the number of cells in an organ or
tissue, often in response to hormonal stimulation. Hypertrophy is an increase in cell
size, atrophy is a decrease in cell size, and metaplasia is the reversible replacement
of one mature cell type with another.
2. A patient has a mutation in the p53 tumor suppressor gene. Which cellular
process is most directly affected by this mutation?
A. DNA repair
B. Apoptosis
C. Cell cycle arrest
D. All of the above
D. All of the above
RATIONALE: The p53 gene is critical for DNA repair, inducing apoptosis when
damage is irreparable, and causing cell cycle arrest to allow for repair. Mutation of
p53 disrupts all these functions.
3. A cell placed in a hypotonic solution will undergo which change?
,A. Shrink
B. Swell
C. Remain unchanged
D. Undergo apoptosis
B. Swell
RATIONALE: In a hypotonic solution, water moves into the cell due to lower
solute concentration outside the cell, causing the cell to swell and potentially lyse.
4. Which type of necrosis is characterized by enzymatic digestion of dead cells,
creating a liquid mass?
A. Coagulative necrosis
B. Liquefactive necrosis
C. Caseous necrosis
D. Fat necrosis
B. Liquefactive necrosis
RATIONALE: Liquefactive necrosis occurs when enzymatic digestion of dead
cells transforms tissue into a liquid mass, commonly seen in brain infarcts and
abscesses.
5. A patient has a deficiency in vitamin C. Which cellular process is impaired?
A. DNA synthesis
B. Collagen synthesis
C. ATP production
D. Protein degradation
B. Collagen synthesis
RATIONALE: Vitamin C is a cofactor for enzymes involved in collagen synthesis.
Deficiency leads to impaired wound healing and scurvy.
6. During which phase of the cell cycle does DNA replication occur?
, A. G1 phase
B. S phase
C. G2 phase
D. M phase
B. S phase
RATIONALE: DNA replication occurs during the S (synthesis) phase of the cell
cycle. G1 and G2 are gap phases, and M phase includes mitosis.
7. Which oncogene is associated with the development of Burkitt lymphoma?
A. HER2
B. MYC
C. RAS
D. BCR-ABL
B. MYC
RATIONALE: The MYC oncogene is translocated in Burkitt lymphoma, leading to
overexpression and uncontrolled cell proliferation.
8. A patient has a mutation in the BRCA1 gene. Which cancer type is most
strongly associated with this mutation?
A. Lung cancer
B. Breast and ovarian cancer
C. Colon cancer
D. Prostate cancer
B. Breast and ovarian cancer
RATIONALE: BRCA1 mutations significantly increase the risk of breast and
ovarian cancers due to impaired DNA repair mechanisms.
9. Which type of hypersensitivity reaction is mediated by IgE antibodies?
A. Type I
B. Type II
