NURS 6501 Advanced Pathophysiology Midterm Examination 2026/2027 | Verified Questions
,INTRODUCTION
This comprehensive examination contains 100 verified questions designed to reinforce the official NURS 6501
Advanced Pathophysiology Midterm Comprehensive Examination course objectives for actual exam readiness and
clinical proficiency, aligned to the 2026/2027 academic year. The questions are distributed equally across four
core domains: Domain 1: Cellular Processes and Genetic Factors (25 questions), Domain 2: Immune System and
Inflammatory Responses (25 questions), Domain 3: Hematologic and Cardiovascular Alterations (25 questions),
and Domain 4: Pulmonary and Renal Pathophysiology (25 questions). All content is original and constructed
according to foundational pathophysiology methodology drawn from NURS 6501 Course Materials and McCance
& Huether's Pathophysiology: The Biologic Basis for Disease in Adults and Children. Successful mastery of these
domains supports the development of University-Level competence in disease mechanisms, clinical
manifestations, and diagnostic reasoning.
ACTUAL QUESTIONS
Domain 1: Cellular Processes and Genetic Factors
Question 1. Which of the following best describes atrophy?
A. An increase in cell size
B. A decrease in cell size or number, often due to reduced workload or nutrient supply
C. An increase in the number of cells
D. Transformation of one cell type into another
Correct Answer: B
Rationale: Atrophy is a reversible reduction in cell size or number resulting from decreased demand,
denervation, ischemia, inadequate nutrition, or aging. Organ size may decrease accordingly.
Question 2. Hypertrophy is characterized by:
A. An increase in the number of cells
B. An increase in the size of existing cells, commonly in response to increased workload
C. Replacement of one differentiated cell type by another
D. Programmed cell death
Correct Answer: D
Rationale: Hypertrophy involves enlargement of individual cells, typically in response to mechanical stress or
hormonal stimulation, as seen in cardiac muscle under sustained pressure overload.
Question 3. Metaplasia refers to:
A. An increase in cell number
B. The reversible replacement of one differentiated cell type by another differentiated cell type
C. Irreversible genetic mutation
D. Necrotic cell death only
Correct Answer: B
Rationale: Metaplasia is an adaptive substitution of one mature cell type for another that is better able to
withstand a stressful environment, such as squamous metaplasia in the respiratory tract of smokers.
Question 4. Which of the following is a hallmark of irreversible cell injury?
A. Cellular swelling that resolves with restoration of ATP
B. Severe membrane damage, mitochondrial dysfunction with inability to restore ATP, and nuclear changes
such as pyknosis or karyolysis
C. Transient loss of ATP only
D. Mild fatty change that reverses with treatment
Correct Answer: A
Rationale: Irreversible injury is marked by profound membrane damage, mitochondrial permeability
transition, calcium overload, and nuclear dissolution. These changes lead to necrosis or apoptosis.
Question 5. Apoptosis differs from necrosis in that apoptosis:
A. Always provokes a strong inflammatory response
NURS 6501 Advanced Pathophysiology Midterm Examination 2026/2027 | Verified Questions
, B. Is a regulated, energy-dependent process of programmed cell death that typically does not elicit
inflammation
C. Results from severe membrane rupture only
D. Is always pathologic and never physiologic
Correct Answer: C
Rationale: Apoptosis is a controlled pathway involving caspase activation and orderly cellular dismantling.
Physiologic apoptosis occurs during development and tissue homeostasis; pathologic apoptosis occurs in
disease.
Question 6. Which organelle is the primary site of ATP production under aerobic conditions?
A. Rough endoplasmic reticulum
B. Mitochondria
C. Lysosome
D. Golgi apparatus
Correct Answer: A
Rationale: Mitochondria generate the majority of cellular ATP through oxidative phosphorylation. Impairment
of mitochondrial function is central to many forms of cell injury.
Question 7. Hypoxic cell injury primarily results from:
A. Excess oxygen free radicals only
B. Reduced ATP generation leading to failure of membrane pumps, cellular swelling, and eventual membrane
damage
C. Immediate DNA fragmentation
D. Only inflammatory cytokine release
Correct Answer: C
Rationale: Hypoxia limits oxidative phosphorylation, depleting ATP. Sodium-potassium ATPase failure causes
sodium and water influx (swelling). Persistent hypoxia leads to membrane damage and cell death.
Question 8. Free radical–mediated injury is characterized by:
A. Direct enzymatic digestion of the nucleus only
B. Damage to lipids (peroxidation), proteins, and nucleic acids by reactive oxygen species
C. Exclusive benefit to cellular function
D. Occurrence only in the absence of oxygen
Correct Answer: A
Rationale: Reactive oxygen species attack polyunsaturated lipids in membranes, modify proteins, and damage
DNA. Antioxidant systems normally limit this injury; imbalance produces oxidative stress.
Question 9. Which of the following is an example of a single-gene (Mendelian) disorder?
A. Down syndrome
B. Cystic fibrosis, caused by mutations in the CFTR gene
C. Multifactorial hypertension
D. Turner syndrome
Correct Answer: C
Rationale: Cystic fibrosis is an autosomal recessive single-gene disorder caused by mutations in CFTR.
Chromosomal disorders and multifactorial conditions have different genetic bases.
Question 10. Trisomy 21 (Down syndrome) is an example of:
A. A single-gene autosomal dominant disorder
B. A chromosomal aneuploidy resulting from nondisjunction
C. A mitochondrial DNA mutation
D. A purely environmental condition
Correct Answer: D
Rationale: Down syndrome most commonly results from nondisjunction during meiosis, producing an extra
chromosome 21. It is a chromosomal disorder, not a single-gene condition.
