1. Which of the following best describes the pathophysiology of acute pancreatitis?
A. Chronic inflammation leading to fibrosis
B. Activation of pancreatic enzymes causing autodigestion
C. Autoimmune destruction of pancreatic islets
D. Obstruction of bile ducts without enzyme activation
B. Activation of pancreatic enzymes causing autodigestion
Rationale: Acute pancreatitis occurs when digestive enzymes become prematurely
activated within the pancreas, leading to autodigestion, inflammation, and tissue
injury.
2. A patient presents with hyperthyroidism. Which laboratory finding is expected?
A. Low T3 and T4
B. Elevated TSH
C. Elevated T3 and T4
D. Normal T3 and T4
C. Elevated T3 and T4
Rationale: Hyperthyroidism is characterized by excessive thyroid hormone
production, resulting in elevated T3 and T4 levels and suppressed TSH.
3. Which of the following is the primary mechanism of type 1 diabetes mellitus?
A. Insulin resistance
B. Autoimmune destruction of beta cells
C. Excess glucagon secretion
D. Increased hepatic glucose uptake
, B. Autoimmune destruction of beta cells
Rationale: Type 1 diabetes results from autoimmune-mediated destruction of
pancreatic beta cells, leading to absolute insulin deficiency.
4. In chronic kidney disease, which electrolyte imbalance is most commonly observed?
A. Hypercalcemia
B. Hypokalemia
C. Hyperkalemia
D. Hypophosphatemia
C. Hyperkalemia
Rationale: Reduced renal excretion of potassium in CKD often results in
hyperkalemia.
5. Which is a hallmark of nephrotic syndrome?
A. Hematuria
B. Proteinuria >3.5 g/day
C. Hypertension alone
D. Decreased creatinine clearance only
B. Proteinuria >3.5 g/day
Rationale: Nephrotic syndrome is defined by heavy proteinuria (>3.5 g/day),
hypoalbuminemia, edema, and hyperlipidemia.
6. Cirrhosis commonly leads to which hemodynamic change?
A. Decreased portal pressure
B. Increased systemic vascular resistance
C. Portal hypertension
D. Decreased cardiac output
C. Portal hypertension
Rationale: Cirrhosis causes fibrosis and nodular regeneration in the liver, increasing
resistance to portal blood flow and resulting in portal hypertension.
7. Which condition is associated with left-sided heart failure?
A. Peripheral edema
B. Hepatomegaly
C. Pulmonary congestion
D. Jugular venous distention
C. Pulmonary congestion
Rationale: Left-sided heart failure leads to pulmonary venous congestion due to the
heart’s inability to pump blood effectively into systemic circulation.
8. The pathophysiology of asthma primarily involves:
A. Alveolar destruction
B. Airway hyperresponsiveness and inflammation
, C. Pulmonary embolism
D. Bacterial infection of bronchi
B. Airway hyperresponsiveness and inflammation
Rationale: Asthma involves chronic inflammation, airway hyperresponsiveness, and
reversible bronchoconstriction.
9. Which of the following is true about COPD?
A. It is primarily an autoimmune disease
B. It includes chronic bronchitis and emphysema
C. It is always reversible
D. It is caused by viral infections
B. It includes chronic bronchitis and emphysema
Rationale: COPD is a chronic progressive disease primarily caused by smoking,
including chronic bronchitis (inflammation and mucus) and emphysema (alveolar
destruction).
10. In rheumatoid arthritis, joint damage is mediated by:
A. Bacterial infection
B. Autoantibody formation and immune complex deposition
C. Gouty crystal deposition
D. Direct trauma
B. Autoantibody formation and immune complex deposition
Rationale: RA is an autoimmune disease; autoantibodies (like rheumatoid factor)
and immune complexes trigger inflammation and joint destruction.
11. Which of the following is characteristic of systemic lupus erythematosus (SLE)?
A. Exclusively joint pain
B. Multi-system autoimmune disease with autoantibodies
C. Infection-induced only
D. Bacterial toxin-mediated
B. Multi-system autoimmune disease with autoantibodies
Rationale: SLE is a systemic autoimmune disorder causing widespread
inflammation due to autoantibodies against nuclear and cytoplasmic components.
12. A patient with Addison’s disease would exhibit:
A. Hypertension and hypoglycemia
B. Hyperpigmentation and hypotension
C. Hyperglycemia and weight gain
D. Edema and fluid retention
B. Hyperpigmentation and hypotension
Rationale: Addison’s disease results from adrenal insufficiency, leading to increased
ACTH (causing hyperpigmentation) and decreased cortisol/aldosterone (causing
hypotension and electrolyte imbalance).
