1. Which of the following best describes the primary pathophysiology of type 1
diabetes mellitus?
A. Insulin resistance in peripheral tissues
B. Autoimmune destruction of pancreatic beta cells
C. Excess hepatic glucose production
D. Increased glucagon secretion
B. Autoimmune destruction of pancreatic beta cells
Rationale: Type 1 diabetes results from an autoimmune attack on beta cells in the
pancreas, leading to absolute insulin deficiency.
2. A patient presents with jaundice, dark urine, and clay-colored stools. Which liver
enzyme pattern suggests cholestasis?
A. Elevated AST and ALT
B. Elevated ALP and GGT
C. Elevated amylase and lipase
D. Normal liver enzymes
B. Elevated ALP and GGT
Rationale: Cholestasis primarily elevates alkaline phosphatase (ALP) and gamma-glutamyl
transferase (GGT), rather than hepatocellular enzymes AST and ALT.
3. Which type of shock is most likely in a patient with severe allergic reaction?
A. Hypovolemic shock
B. Cardiogenic shock
, C. Neurogenic shock
D. Anaphylactic shock
D. Anaphylactic shock
Rationale: Anaphylactic shock is a distributive shock caused by a severe IgE-mediated
allergic reaction, leading to vasodilation and increased vascular permeability.
4. What is the hallmark pathophysiologic feature of chronic obstructive pulmonary
disease (COPD)?
A. Reversible airway obstruction
B. Loss of elastic recoil and airflow limitation
C. Alveolar hyperplasia
D. Bronchial hypersecretion only
B. Loss of elastic recoil and airflow limitation
Rationale: COPD is characterized by persistent airflow limitation due to small airway
disease and alveolar destruction, reducing lung elastic recoil.
5. A patient with congestive heart failure has elevated BNP levels. What is the primary
pathophysiologic mechanism leading to BNP elevation?
A. Myocardial necrosis
B. Ventricular wall stretch due to volume overload
C. Peripheral vasoconstriction
D. Renal tubular injury
B. Ventricular wall stretch due to volume overload
Rationale: BNP is released from ventricular myocytes in response to increased wall stress
from volume or pressure overload.
6. In metabolic acidosis, which compensatory mechanism is expected?
A. Hypoventilation to retain CO2
B. Hyperventilation to decrease CO2
C. Increased renal bicarbonate excretion
D. Increased aldosterone secretion
B. Hyperventilation to decrease CO2
Rationale: Respiratory compensation for metabolic acidosis involves increased ventilation
to reduce CO2 and help restore pH.
7. The pathophysiology of peptic ulcer disease most commonly involves:
A. Increased gastric motility
B. H. pylori infection and imbalance of mucosal defense
C. Autoimmune destruction of parietal cells
D. Excess pancreatic enzyme secretion
, B. H. pylori infection and imbalance of mucosal defense
Rationale: H. pylori infection disrupts mucosal defenses, increasing susceptibility to acid-
peptic injury, which is central to peptic ulcer disease.
8. Which is the primary mechanism of hypoxemia in a patient with pneumonia?
A. Hypoventilation
B. Diffusion impairment
C. V/Q mismatch
D. Shunt
C. V/Q mismatch
Rationale: Pneumonia causes alveolar filling and inflammation, leading to ventilation-
perfusion mismatch and impaired oxygenation.
9. The most common cause of hyperthyroidism is:
A. Thyroid adenoma
B. Graves disease
C. Hashimoto thyroiditis
D. Iodine deficiency
B. Graves disease
Rationale: Graves disease is an autoimmune disorder characterized by thyroid-stimulating
immunoglobulins that activate TSH receptors, causing hyperthyroidism.
10. Which electrolyte abnormality is expected in a patient with Addison disease?
A. Hypernatremia
B. Hypokalemia
C. Hyponatremia and hyperkalemia
D. Hypercalcemia
C. Hyponatremia and hyperkalemia
Rationale: Addison disease involves adrenal insufficiency with deficient aldosterone,
leading to sodium loss and potassium retention.
11. A patient with nephrotic syndrome is at risk for which complication?
A. Hypercoagulability
B. Hypotension
C. Hypolipidemia
D. Hypoglycemia
A. Hypercoagulability
Rationale: Nephrotic syndrome causes urinary loss of antithrombotic proteins like
antithrombin III, increasing the risk of thrombosis.
12. The hallmark feature of multiple sclerosis (MS) pathophysiology is:
A. Neuronal apoptosis due to ischemia

1. Which of the following best describes the primary pathophysiology of type 1
diabetes mellitus?
A. Insulin resistance in peripheral tissues
B. Autoimmune destruction of pancreatic beta cells
C. Excess hepatic glucose production
