Pulmonary Disorders
Final Test Review (Qns & Ans)
2025
1. Multiple Choice
- Question: Which of the following conditions is characterized
by chronic obstruction of airflow due to inflammation and mucus
production?
- A. Asthma
- B. Chronic Obstructive Pulmonary Disease (COPD)
- C. Pulmonary embolism
- D. Tuberculosis
- ANS: B. Chronic Obstructive Pulmonary Disease (COPD)

, - Rationale: COPD is characterized by persistent respiratory
symptoms and airflow limitation due to airway and/or alveolar
abnormalities, typically caused by significant exposure to noxious
particles or gases.
2. Fill-in-the-Blank
- Question: The primary function of alveoli in the lungs is to
facilitate the exchange of ________ and ________ between the
blood and the air.
- ANS: oxygen, carbon dioxide
- Rationale: Alveoli are tiny sacs in the lungs where gas
exchange occurs. Oxygen diffuses into the blood, while carbon
dioxide diffuses out of the blood into the alveolar air.
3. True/False
- Question: Pulmonary fibrosis is a condition that results in the
thickening and scarring of lung tissue.
- ANS: True
- Rationale: Pulmonary fibrosis involves the formation of scar
tissue in the lungs, leading to reduced elasticity and impaired gas
exchange.
4. Multiple Response

, - Question: Select all that apply. Which of the following are risk
factors for developing pneumonia?
- A. Smoking
- B. Immune suppression
- C. Diabetes
- D. Regular exercise
- ANSs: A. Smoking, B. Immune suppression, C. Diabetes
- Rationale: Risk factors for pneumonia include smoking,
immune suppression, and diabetes, which increase susceptibility
to respiratory infections.
5. Multiple Choice
- Question: In which of the following conditions does a blood
clot block one or more arteries in the lungs?
- A. Asthma
- B. Pulmonary embolism
- C. Chronic bronchitis
- D. Emphysema
- ANS: B. Pulmonary embolism
- Rationale: A pulmonary embolism occurs when a blood clot,
usually from the legs, travels to the lungs and blocks a pulmonary
artery, obstructing blood flow.

, 6. Fill-in-the-Blank
- Question: The process of measuring the volume of air inhaled
and exhaled by the lungs is called ________.
- ANS: spirometry
- Rationale: Spirometry is a common pulmonary function test
that measures lung function, specifically the volume and/or flow
of air that can be inhaled and exhaled.
7. True/False
- Question: Acute respiratory distress syndrome (ARDS) is a
life-threatening condition characterized by rapid onset of
widespread inflammation in the lungs.
- ANS: True
- Rationale: ARDS involves severe inflammation and fluid
accumulation in the alveoli, leading to acute respiratory failure
and reduced oxygen levels.
8. Multiple Response
- Question: Select all that apply. Which of the following are
clinical manifestations of asthma?
- A. Wheezing
- B. Dyspnea
