100% Correct Solutions
1. What is the primary cause of chronic obstructive pulmonary disease (COPD)?
A. Genetic mutation
B. Long-term exposure to irritants
C. Acute viral infection
D. Autoimmune response
Correct Answer: B
Rationale: COPD is primarily caused by prolonged exposure to irritants like cigarette
smoke, leading to airway inflammation and alveolar damage (Week 7 topic: Respiratory
disorders).
2. Which condition is characterized by reversible airway obstruction?
A. Emphysema
B. Chronic bronchitis
C. Asthma
D. Pulmonary fibrosis
Correct Answer: C
Rationale: Asthma involves reversible bronchoconstriction triggered by allergens or
irritants, unlike the irreversible damage in COPD (Week 7 topic: Asthma
pathophysiology).
3. What is the hallmark symptom of pneumonia?
A. Chest pain
B. Productive cough with fever
C. Peripheral edema
D. Joint swelling
Correct Answer: B
Rationale: Pneumonia presents with fever, productive cough, and sputum due to lung
infection (Week 7 topic: Infectious respiratory diseases).
4. Which diagnostic test is most specific for assessing lung function in COPD?
A. Chest X-ray
B. Spirometry
C. Blood gas analysis
D. CT scan
Correct Answer: B
Rationale: Spirometry measures airflow obstruction (FEV1/FVC ratio) to diagnose and
monitor COPD (Week 7 topic: Respiratory diagnostics).
5. What is the primary pathophysiological feature of emphysema?
A. Airway inflammation
