1. Liquefactive necrosis is best defined as which of the following?
A. Deposition of fibrin in blood vessels
B. Tissue that becomes firm and preserved
C. Tissue that loses structure and becomes a liquid mass
D. Death of fat cells with calcification
• Correct Answer: Tissue that loses structure and becomes a liquid mass
Rationale: Liquefactive necrosis occurs when enzymatic digestion causes
tissue to dissolve into a liquid form, commonly seen in infections.
Example: Brain abscess, bacterial pneumonia
2. Liquefactive necrosis is most commonly caused by:
A. Trauma
B. Infection and inflammation
C. Autoimmune disease
D. Ischemia of skeletal muscle
• Correct Answer: Infection and inflammation
Rationale: Enzymes released during infection digest tissue, producing a
liquid necrotic mass.
Example: Brain abscess
,3. Caseous necrosis is characterized by:
A. Liquid tissue destruction
B. Firm fibrotic tissue
C. Soft, cheese-like necrotic material
D. Hemorrhagic necrosis
• Correct Answer: Soft, cheese-like necrotic material
Rationale: Caseous necrosis produces a granular, cheese-like appearance
typically associated with granulomatous inflammation.
Example: Tuberculosis
4. Caseous necrosis is most commonly associated with:
A. Pancreatitis
B. Tuberculosis and fungal infections
C. Trauma to adipose tissue
D. Myocardial infarction
• Correct Answer: Tuberculosis and fungal infections
Rationale: Granulomatous infections produce caseous necrosis.
Example: Granulomatous inflammation in tuberculosis
5. Fat necrosis occurs when:
A. Brain tissue liquefies
B. Fat cells die and become surrounded by a fibrous capsule
C. Blood vessels rupture
D. Tissue becomes calcified
• Correct Answer: Fat cells die and become surrounded by a fibrous
capsule
Rationale: Lipase release breaks down fat cells, resulting in necrosis and
fibrosis.
Example: Pancreatitis
,6. Common causes of fat necrosis include:
A. Viral infections
B. Trauma, pancreatitis, and ischemia
C. Autoimmune disorders
D. Bacterial pneumonia
• Correct Answer: Trauma, pancreatitis, and ischemia
Rationale: Fat necrosis frequently follows injury to adipose tissue or
enzyme release.
Example: Fat emboli, pancreatitis
7. Fibrinoid necrosis is best described as:
A. Liquid tissue destruction
B. Deposition of fibrin and proteins in blood vessels
C. Necrosis of adipose tissue
D. Granuloma formation
• Correct Answer: Deposition of fibrin and proteins in blood vessels
Rationale: Immune-mediated vascular damage leads to fibrin deposition in
vessel walls.
Example: Rheumatoid vasculitis
8. Fibrinoid necrosis is commonly caused by:
A. Bacterial infection
B. Autoimmune disease and hyperacute transplant rejection
C. Trauma
D. Hypoxia
• Correct Answer: Autoimmune disease and hyperacute transplant
rejection
Rationale: Immune complex deposition damages vessels.
Example: Membranous nephropathy
, 9. Chronic alcohol use most commonly leads to which liver condition?
A. Hepatitis B
B. Fatty liver progressing to cirrhosis
C. Liver abscess
D. Hemochromatosis
• Correct Answer: Fatty liver progressing to cirrhosis
Rationale: Alcohol causes fat accumulation, inflammation, and fibrosis.
Example: Cirrhosis
10.Chronic alcohol use can lead to inflammation of the pancreas known as:
A. Pancreatic insufficiency
B. Pancreatitis
C. Pancreatic tumor
D. Hyperinsulinemia
• Correct Answer: Pancreatitis
Rationale: Alcohol damages pancreatic tissue leading to inflammation.
Example: Chronic pancreatitis
11.Chronic alcohol use increases the risk for which cardiac complication?
A. Heart block
B. Cardiomyopathy and hypertension
C. Valvular stenosis
D. Bradycardia
• Correct Answer: Cardiomyopathy and hypertension
Rationale: Alcohol weakens cardiac muscle and raises blood pressure.
