1. A patient experiences prolonged tissue hypoxia due to peripheral arterial
disease. Which cellular change is most directly associated with reversible cell
injury?
A. Lysosomal membrane rupture
B. Cellular swelling due to sodium–potassium pump failure
C. Nuclear pyknosis
D. Mitochondrial membrane destruction
Rationale: Reversible cell injury is characterized by ATP depletion leading to
Na⁺/K⁺ pump dysfunction and cellular swelling; nuclear and lysosomal damage
indicate irreversible injury.
2. During apoptosis, which process differentiates it most clearly from
necrosis?
A. Cellular ATP depletion
B. Inflammatory response activation
C. Programmed cell death without inflammation
D. Cell membrane rupture
Rationale: Apoptosis is an energy-dependent, regulated process that does not elicit
inflammation, unlike necrosis.
3. A nurse practitioner explains ischemia–reperfusion injury to a patient.
Which mechanism is primarily responsible for this phenomenon?
A. Reduced nitric oxide synthesis
,B. Generation of reactive oxygen species
C. Decreased intracellular calcium
D. Increased anaerobic glycolysis
Rationale: Reperfusion introduces oxygen that generates free radicals, causing
additional cellular damage.
4. Which electrolyte imbalance is most likely to occur early in acute renal
failure due to decreased excretion?
A. Hypocalcemia
B. Hyponatremia
C. Hyperkalemia
D. Hypophosphatemia
Rationale: Impaired renal excretion of potassium leads to hyperkalemia, a life-
threatening complication.
5. A patient with chronic inflammation is at increased risk for which long-
term outcome?
A. Enhanced tissue regeneration
B. Fibrosis and loss of organ function
C. Resolution without sequelae
D. Decreased cytokine production
Rationale: Chronic inflammation promotes ongoing tissue injury and fibrotic
repair.
6. Which cytokine is most responsible for initiating the acute-phase response?
A. IL-10
B. IL-6
C. IL-4
,D. TGF-β
Rationale: IL-6 stimulates hepatic production of acute-phase proteins such as
CRP.
7. In Type I hypersensitivity reactions, which immunoglobulin mediates the
response?
A. IgG
B. IgM
C. IgE
D. IgA
Rationale: IgE binds to mast cells and basophils, triggering histamine release
upon antigen exposure.
8. Which finding best differentiates septic shock from hypovolemic shock?
A. Decreased cardiac output
B. Profound vasodilation with warm skin
C. Reduced preload
D. Elevated systemic vascular resistance
Rationale: Septic shock is characterized by vasodilation and initially warm,
flushed skin.
9. A patient has a mutation in a tumor suppressor gene. What is the primary
consequence?
A. Increased apoptosis
B. Reduced cell proliferation
C. Loss of cell cycle regulation
D. Enhanced DNA repair
, Rationale: Tumor suppressor gene mutations remove inhibitory controls on cell
division.
10. Which acid–base disturbance is expected in prolonged vomiting?
A. Metabolic acidosis
B. Metabolic alkalosis
C. Respiratory acidosis
D. Respiratory alkalosis
Rationale: Loss of gastric acid leads to metabolic alkalosis.
11. In left-sided heart failure, which clinical manifestation is most directly
related to pulmonary congestion?
A. Peripheral edema
B. Jugular venous distention
C. Crackles on lung auscultation
D. Hepatosplenomegaly
Rationale: Left-sided failure causes pulmonary venous congestion, producing
crackles.
12. Which mechanism best explains edema formation in nephrotic syndrome?
A. Increased capillary permeability only
B. Decreased plasma oncotic pressure
C. Increased lymphatic obstruction
D. Elevated arterial pressure
Rationale: Hypoalbuminemia reduces oncotic pressure, allowing fluid to shift into
interstitial spaces.
