NGR 5149 ADVANCED PATHOPHYSIOLOGY FINAL EXAM
Comprehensive Practice Exam (300 Questions)
This comprehensive practice exam covers the core content areas required for the NGR 5149 Advanced
Pathophysiology Across the Lifespan course. The questions are designed to test understanding of cellular
and tissue pathophysiology, inflammation and immunity, genetics and oncology, and pathophysiology
across all major body systems (cardiovascular, pulmonary, renal, gastrointestinal, neurological,
endocrine, and musculoskeletal). All questions are scenario-based, randomized, and include correct
answers with detailed rationales to reinforce learning.
SECTION 1: CELLULAR PATHOPHYSIOLOGY & ADAPTATION (Questions 1-36)
1. A hospitalized patient develops cellular swelling after prolonged hypoxia. Which intracellular process is
the primary cause of this change?
A) Increased lysosomal membrane stability
, Page 2 of 186
B) Failure of ATP-dependent sodium-potassium pumps
C) Increased protein synthesis
D) Activation of apoptosis
Answer: B
Hypoxia leads to decreased ATP production, impairing Na⁺/K⁺-ATPase function and causing intracellular
sodium and water accumulation, resulting in cellular swelling. This is the hallmark of reversible cell injury.
2. Which mechanism best explains reperfusion injury following ischemia?
A) Restoration of normal mitochondrial ATP production
B) Decreased neutrophil activation
C) Generation of reactive oxygen species and inflammatory mediators
D) Suppression of cytokine release
Answer: C
Reperfusion introduces oxygen that generates free radicals (reactive oxygen species) and triggers
inflammation, worsening tissue damage rather than reversing it. This paradoxical injury occurs when
blood supply is restored to ischemic tissue.

3. A patient with chronic inflammation is most likely to demonstrate which histologic feature?
A) Neutrophilic predominance
B) Mononuclear cell infiltration
C) Fibrin deposition
D) Extensive edema
Answer: B
Chronic inflammation is characterized by mononuclear cell infiltration (macrophages, lymphocytes,
plasma cells), tissue destruction, and fibrosis, rather than acute neutrophil dominance. Acute
inflammation is characterized by neutrophilic predominance.
4. Which component of the cell produces hydrogen peroxide (H₂O₂) by using oxygen to remove hydrogen
atoms from specific substrates in an oxidative reaction?
A) Lysosomes
B) Peroxisomes
C) Ribosomes
D) Golgi apparatus
, Page 4 of 186
Answer: B
Peroxisomes are organelles that contain oxidative enzymes and produce hydrogen peroxide (H₂O₂) as a
byproduct of oxidation reactions. They play a role in lipid metabolism and detoxification.
5. Which cell component is capable of cellular autodigestion when it is released during cell injury?
A) Lysosomes
B) Ribosomes
C) Smooth endoplasmic reticulum
D) Golgi complex
Answer: A
Lysosomes contain hydrolytic enzymes capable of digesting cellular components. When released during
cell injury, these enzymes can cause autodigestion (autolysis) of the cell.
6. A mutation affecting the p53 gene increases cancer risk primarily because p53 normally:
A) Enhances angiogenesis
B) Induces cell cycle arrest and apoptosis after DNA damage
C) Promotes cellular differentiation
