🫁 SECTION 1: PULMONARY PATHOPHYSIOLOGY
Questions 1–45
❓ Question 1
What is the primary purpose of the lungs?
• A) To filter blood
• B) To provide movement of air from the external environment to the point
of gas exchange
, • C) To regulate body temperature
• D) To produce red blood cells
✅ Correct Answer: B
Rationale: The primary purpose of the lungs is to provide movement of air from the
external environment to the point of gas exchange in the alveoli. This process, known as
ventilation, is essential for oxygen delivery to the blood and removal of carbon dioxide.
❓ Question 2
What is the functional unit of the lungs where gas exchange occurs?
• A) Bronchiole
• B) Alveolus
• C) Pleura
• D) Trachea
✅ Correct Answer: B
Rationale: The alveolus is the functional unit of the lungs where gas exchange occurs.
Oxygen diffuses from the alveoli into the pulmonary capillaries, and carbon dioxide
diffuses from the blood into the alveoli.
❓ Question 3
What is the primary cause of obstructive lung diseases?
• A) Airway obstruction leading to increased resistance to airflow
, • B) Restriction of lung expansion
• C) Decreased surfactant production
• D) Increased alveolar elasticity
✅ Correct Answer: A
Rationale: Obstructive lung diseases (e.g., COPD, asthma, bronchiectasis) are
characterized by airway obstruction that increases resistance to airflow, making
expiration difficult.
❓ Question 4
What is the primary cause of restrictive lung diseases?
• A) Airway obstruction
• B) Decreased lung compliance and reduced lung expansion
• C) Increased surfactant production
• D) Bronchial hyperreactivity
✅ Correct Answer: B
Rationale: Restrictive lung diseases (e.g., pulmonary fibrosis, sarcoidosis) are
characterized by decreased lung compliance and reduced lung expansion, limiting
the ability to inhale fully.
❓ Question 5
What is the pathophysiology of chronic obstructive pulmonary disease (COPD)?
