1.
A patient with chronic obstructive pulmonary disease (COPD) is experiencing
hypoxemia. Which physiological change contributes most to this condition?
A. Increased alveolar surface area
B. Destruction of alveolar walls
C. Increased lung compliance
D. Hypersecretion of surfactant
Correct Answer: B. Destruction of alveolar walls
Rationale: In emphysema, alveolar walls are destroyed, decreasing surface area for gas
exchange and leading to hypoxemia. Lung compliance is increased, but this does not
improve oxygenation. Surfactant secretion is unrelated to COPD pathogenesis.

2.
A patient with left-sided heart failure is at risk for which major complication?
A. Peripheral edema
B. Pulmonary congestion
C. Hepatomegaly
D. Jugular vein distension
Correct Answer: B. Pulmonary congestion
Rationale: Left-sided heart failure leads to blood backing up into the pulmonary
circulation, causing pulmonary edema and dyspnea. Right-sided failure is associated
with systemic congestion (JVD, hepatomegaly, peripheral edema).
3.
Which electrolyte imbalance is most commonly seen in chronic kidney disease?
A. Hypokalemia
B. Hyperkalemia
C. Hypocalcemia
D. Hypernatremia
Correct Answer: B. Hyperkalemia
Rationale: Impaired renal excretion leads to potassium retention, resulting in
hyperkalemia, which can cause arrhythmias. Hypocalcemia may also occur but is

secondary to impaired vitamin D activation.
4.
In type 1 diabetes mellitus, what is the primary pathophysiological defect?
A. Insulin resistance
B. Destruction of beta cells
C. Increased glucagon sensitivity
D. Excessive cortisol production
Correct Answer: B. Destruction of beta cells
Rationale: Type 1 diabetes results from autoimmune destruction of pancreatic beta
cells, leading to absolute insulin deficiency. Insulin resistance characterizes type 2
diabetes.
5.
Which condition results from hypersecretion of growth hormone in adulthood?
A. Gigantism
B. Acromegaly
C. Dwarfism
D. Addison’s disease
Correct Answer: B. Acromegaly
Rationale: Excess GH after epiphyseal closure causes acromegaly, leading to enlarged

hands, feet, and facial bones. Gigantism occurs if GH excess happens before growth
plate closure.
6.
Which of the following is a primary risk factor for developing peptic ulcer disease?
A. Helicobacter pylori infection
B. High-fiber diet
C. Low-salt diet
D. Vitamin D deficiency
Correct Answer: A. Helicobacter pylori infection
Rationale: H. pylori damages gastric mucosa, leading to ulcers. Other causes include
NSAID use and stress, not dietary salt or vitamin D deficiency.
7.
A patient with cirrhosis develops ascites. Which pathophysiological mechanism is
primarily responsible?
A. Increased plasma oncotic pressure
B. Portal hypertension
C. Increased urine output
D. Hypoglycemia
Correct Answer: B. Portal hypertension
