chronic obstructive pulmonary disease (COPD)?
- A) Inflammation and narrowing of the airways
- B) Accumulation of fluid in the alveoli
- C) Destruction of alveolar walls and loss of elastic recoil
- D) Infection of the lung parenchyma
- ANS: C) Destruction of alveolar walls and loss of elastic
recoil



©2024/2025

, - Rationale: COPD is characterized by the destruction of
alveolar walls and loss of elastic recoil, leading to airflow
limitation and impaired gas exchange.


2. What is the primary cause of pulmonary embolism?
- A) Bacterial infection
- B) Obstruction of a pulmonary artery by a thrombus
- C) Chronic inflammation
- D) Genetic mutation
- ANS: B) Obstruction of a pulmonary artery by a thrombus
- Rationale: Pulmonary embolism is primarily caused by the
obstruction of a pulmonary artery by a thrombus, leading to
impaired blood flow and gas exchange.


3. Which of the following is NOT a common risk factor for the
development of asthma?
- A) Allergens
- B) Tobacco smoke
- C) Physical activity
- D) Respiratory infections
- ANS: C) Physical activity


©2024/2025

, - Rationale: Physical activity is generally beneficial for lung
health, while allergens, tobacco smoke, and respiratory infections
are common risk factors for the development of asthma.


Fill-in-the-Blank Questions
4. The __________ is the primary muscle responsible for
inspiration.
- ANS: Diaphragm
- Rationale: The diaphragm is the primary muscle responsible
for inspiration, contracting to create negative pressure and draw
air into the lungs.


5. In the process of gas exchange, __________ diffuses from the
alveoli into the blood, while __________ diffuses from the blood
into the alveoli.
- ANS: Oxygen, Carbon dioxide
- Rationale: Oxygen diffuses from the alveoli into the blood,
while carbon dioxide diffuses from the blood into the alveoli
during gas exchange.


6. The __________ is a measure of the maximum amount of air
that can be exhaled after a maximum inhalation.
- ANS: Vital capacity


©2024/2025

, - Rationale: The vital capacity is a measure of the maximum
amount of air that can be exhaled after a maximum inhalation,
reflecting lung function.


True/False Questions
7. True or False: Acute respiratory distress syndrome (ARDS) is
characterized by the rapid onset of severe respiratory failure.
- ANS: True
- Rationale: ARDS is characterized by the rapid onset of
severe respiratory failure, often resulting from acute lung injury or
inflammation.


8. True or False: Pulmonary fibrosis is a reversible condition
characterized by the thickening and scarring of lung tissue.
- ANS: False
- Rationale: Pulmonary fibrosis is an irreversible condition
characterized by the thickening and scarring of lung tissue,
leading to progressive lung dysfunction.


9. True or False: Cystic fibrosis is a genetic disorder that affects
the respiratory and digestive systems.
- ANS: True
