NR 507 Advanced Pathophysiology Midterm Examination 2026/2027 | Verified Questions
,INTRODUCTION
This comprehensive examination contains 100 verified questions designed to reinforce the official
Chamberlain College of Nursing NR 507 Advanced Pathophysiology Midterm course objectives for actual
exam readiness and clinical proficiency, aligned to the 2026/2027 academic year. The questions are
original and address four core domains: Cellular and Genetic Alterations, Immune and Hematologic
Disorders, Neurological and Endocrine Pathophysiology, and Cardiovascular and Pulmonary
Pathophysiology. Each item requires application of foundational advanced pathophysiology knowledge
drawn from established NR 507 curriculum materials and evidence-based disease mechanisms.
Successful completion of this examination supports development of the clinical judgment required for
accurate pathophysiologic reasoning in advanced nursing care.
ACTUAL QUESTIONS
Domain 1: Cellular and Genetic Alterations
Question 1. Which process describes programmed cell death that is orderly and does not
typically provoke inflammation?
A. Necrosis
B. Apoptosis
C. Metaplasia
D. Hyperplasia
Correct Answer: C
Rationale: Apoptosis is a regulated form of cell death that eliminates damaged or unnecessary cells
without releasing intracellular contents that would trigger inflammation.
Question 2. Hypoxic injury leads to cellular swelling primarily because of:
A. Increased ATP production
B. Failure of the sodium-potassium ATPase pump due to ATP depletion, allowing sodium and water
to enter the cell
C. Decreased membrane permeability to sodium
D. Enhanced oxidative phosphorylation
Correct Answer: B
Rationale: Hypoxia reduces ATP, impairing the Na+/K+ ATPase. Sodium accumulates intracellularly,
drawing water and causing cellular swelling.
Question 3. Which type of cellular adaptation involves an increase in the number of cells in
a tissue?
A. Hypertrophy
B. Atrophy
C. Hyperplasia
D. Metaplasia
Correct Answer: C
Rationale: Hyperplasia is an increase in cell number. Hypertrophy is an increase in cell size; atrophy is
a decrease in size or number; metaplasia is replacement by a different cell type.
Question 4. Free radical injury is primarily mediated by:
A. Direct enzymatic digestion of proteins only
B. Reactive oxygen species that damage lipids, proteins, and DNA through oxidative reactions
C. Complete inhibition of all metabolic pathways
D. Increased production of ATP
Correct Answer: D
Rationale: Reactive oxygen species (free radicals) cause lipid peroxidation, protein modification, and
DNA damage, contributing to cell injury and death.

, Question 5. Which genetic term describes a situation in which a single gene influences
multiple phenotypic traits?
A. Pleiotropy
B. Epistasis
C. Penetrance
D. Expressivity
Correct Answer: C
Rationale: Pleiotropy occurs when one gene affects multiple, seemingly unrelated phenotypic traits.
Question 6. A mutation that results in a premature stop codon and truncated protein is
best classified as a:
A. Silent mutation
B. Missense mutation
C. Nonsense mutation
D. Frameshift mutation that always preserves the reading frame
Correct Answer: B
Rationale: A nonsense mutation changes a codon that codes for an amino acid into a stop codon,
producing a truncated and usually nonfunctional protein.
Question 7. Which cellular organelle is the primary site of ATP production through
oxidative phosphorylation?
A. Rough endoplasmic reticulum
B. Golgi apparatus
C. Mitochondria
D. Lysosome
Correct Answer: A
Rationale: Mitochondria generate the majority of cellular ATP via the electron transport chain and
oxidative phosphorylation.
Question 8. Metaplasia is best defined as:
A. An increase in cell size
B. A reversible change in which one differentiated cell type is replaced by another differentiated cell
type
C. Irreversible malignant transformation
D. A decrease in cell number
Correct Answer: D
Rationale: Metaplasia is a reversible adaptive replacement of one adult cell type by another, often in
response to chronic irritation.
Question 9. Which mechanism of cell injury is most closely associated with reperfusion
after ischemia?
A. Immediate restoration of normal function without risk
B. Generation of reactive oxygen species when oxygen is reintroduced to previously ischemic tissue
C. Complete absence of inflammatory response
D. Decreased calcium influx
Correct Answer: C
Rationale: Reperfusion injury occurs when oxygen returns to ischemic tissue, leading to a burst of
reactive oxygen species, calcium overload, and inflammation.
Question 10. Autosomal dominant inheritance is characterized by:
A. Disease expression only when two mutant alleles are present
B. Disease expression when only one mutant allele is present, with vertical transmission across
generations
