GENERAL INSTRUCTIONS
Difficulty Level: Advanced / Hard (Mixed)
Target Audience: Nursing students (BSN, MSN, DNP), registered nurses, and nurse practitioner
candidates
Format: Each question has four options (A–D). Only ONE answer is correct.
Marking Convention: 🟢 indicates the start of each question. 🔴🔴 precedes the correct answer.
Answer Rationale: Provided immediately after each question.
Sources: Questions are derived from McCance & Huether's Pathophysiology: The Biologic Basis
for Disease in Adults and Children (9th ed.), Porth's Pathophysiology: Concepts of Altered Health
States (11th ed.), and verified advanced pathophysiology examination banks.
SECTION I: CELLULAR ADAPTATION, INJURY, AND DEATH
🟢 1. A 68-year-old patient with long-standing hypertension develops thickening of the left ventricular
wall. Which cellular adaptation does this represent?
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
🔴🔴 Correct Answer: B. Hypertrophy
Rationale: Hypertrophy is an increase in cell size that occurs in tissues incapable of cell division, such as
cardiac muscle. Chronic pressure overload from hypertension triggers increased protein synthesis and
sarcomere assembly, leading to ventricular wall thickening. Hyperplasia involves increased cell number;
metaplasia is replacement of one mature cell type by another; dysplasia refers to disordered growth.
🟢 2. A patient develops tissue hypoxia following severe blood loss. Which cellular change occurs
earliest during hypoxic injury?
A. Nuclear fragmentation
B. Decreased ATP production
,C. Lysosomal rupture
D. Membrane calcification
🔴🔴 Correct Answer: B. Decreased ATP production
Rationale: Hypoxia reduces oxidative phosphorylation and ATP generation. ATP depletion impairs
sodium-potassium ATPase activity, causing cellular sodium and water accumulation (hydropic swelling).
Nuclear fragmentation, lysosomal rupture, and calcification occur later in irreversible injury.
🟢 3. Which mechanism most directly explains cellular swelling during reversible injury?
A. Increased protein synthesis
B. Failure of the sodium-potassium pump
C. Increased lysosomal activity
D. Increased DNA replication
🔴🔴 Correct Answer: B. Failure of the sodium-potassium pump
Rationale: ATP depletion from hypoxia or toxins impairs Na⁺/K⁺-ATPase. Sodium accumulates
intracellularly, followed by water movement into the cell, producing hydropic swelling. This is the
hallmark of reversible cellular injury.
🟢 4. Which finding is most characteristic of irreversible cellular injury?
A. Cellular swelling
B. Fatty change
C. Severe mitochondrial dysfunction with inability to reverse injury
D. Mild endoplasmic reticulum dilation
🔴🔴 Correct Answer: C. Severe mitochondrial dysfunction with inability to reverse injury
Rationale: Irreversible injury is associated with profound mitochondrial dysfunction and loss of
membrane integrity. Once adequate mitochondrial function cannot be restored, the cell progresses
toward death via necrosis or apoptosis.
🟢 5. Reperfusion of ischemic tissue can paradoxically worsen cellular injury primarily because of:
A. Reduced oxygen availability
B. Reactive oxygen species generation
C. Reduced calcium entry
D. Decreased inflammatory signaling
🔴🔴 Correct Answer: B. Reactive oxygen species generation
, Rationale: Reintroduction of oxygen during reperfusion generates reactive oxygen species (ROS) that
damage lipids, proteins, DNA, and cellular membranes. Calcium overload and inflammatory activation
further contribute to reperfusion injury.
🟢 6. Which process is characterized by programmed cellular death without significant surrounding
inflammation?
A. Necrosis
B. Apoptosis
C. Gangrene
D. Autolysis
🔴🔴 Correct Answer: B. Apoptosis
Rationale: Apoptosis is regulated cell death involving cellular shrinkage, chromatin condensation, and
formation of apoptotic bodies. Cellular contents remain contained within membranes, limiting
inflammation. Necrosis triggers inflammation due to release of cellular contents.
🟢 7. Which intracellular organelle plays the central role in initiating the intrinsic apoptotic pathway?
A. Golgi apparatus
B. Lysosome
C. Mitochondrion
D. Ribosome
🔴🔴 Correct Answer: C. Mitochondrion
Rationale: Mitochondrial outer membrane permeabilization permits cytochrome c release, which
activates caspases through the apoptosome pathway. This is the intrinsic (mitochondrial) apoptotic
pathway.
🟢 8. A 55-year-old smoker undergoes a bronchial biopsy that reveals replacement of normal columnar
epithelium with stratified squamous epithelium. This finding is best described as:
A. Hyperplasia
B. Metaplasia
C. Dysplasia
D. Anaplasia
🔴🔴 Correct Answer: B. Metaplasia
Rationale: Metaplasia is the reversible replacement of one mature cell type by another, often as an
adaptation to chronic irritation. In smokers, columnar bronchial epithelium is replaced by stratified
squamous epithelium. Dysplasia involves disordered growth and maturation but not a change in cell
type.
