Obstructive Lung Disease MCQs: practice questions

Sample Obstructive Lung Disease multiple-choice questions from Respiratory.

In cystic fibrosis, pancreatic insufficiency occurs through a mechanism similar to which pulmonary process?
- A. Direct autoimmune pancreatic destruction unrelated to CFTR
- B. Isolated pancreatic tumor formation
- C. A process largely unrelated to the pulmonary CFTR defect
- D. Thick secretions obstructing pancreatic ducts, like airways
- E. Excess pancreatic enzyme secretion causing autodigestion
Allergic bronchopulmonary aspergillosis is a hypersensitivity reaction most commonly seen in which patient population?
- A. Patients with asthma or cystic fibrosis
- B. Patients with no underlying lung disease
- C. mainly immunocompromised transplant recipients
- D. mainly healthy young athletes
- E. Patients with isolated coronary artery disease
Chronic asthma leads to airway remodeling, which includes which structural changes?
- A. Complete loss of airway smooth muscle
- B. Alveolar wall destruction comparable to emphysema
- C. Isolated cartilage calcification
- D. Smooth muscle hypertrophy and subepithelial fibrosis
- E. Complete absence of any structural change over time
Which best describes the DLCO (diffusion capacity) finding typically seen in predominant emphysema versus predominant chronic bronchitis?
- A. DLCO is comparable in both conditions
- B. DLCO reduced in emphysema, relatively preserved in bronchitis
- C. DLCO is reduced in chronic bronchitis but normal in emphysema
- D. DLCO has no diagnostic relevance in obstructive lung disease
- E. DLCO is commonly elevated in both conditions
Loss of elastic recoil in emphysema contributes to airflow obstruction primarily through which mechanism?
- A. Increased airway smooth muscle tone
- B. Excess mucus production obstructing the airway lumen
- C. Direct bronchial wall calcification
