2026/2027
GRADED A+ .
,1. Pulmonary Function Tests/Spirometry: What can cause it to vary ✔✔ CORRECT ANSWER Age Sex
Height Weight
2. Pulmonary Function Tests/Spirometry: Used to evaluate: Peop eval of lungs and
pulmonary reserve
response to bronchodilator therapy
ditterentiate between restrictive and obstructive chronic pulmonary disease Determine capacity of lungs
Inhalation allergy tests
3. Pulmonary Function Tests/Spirometry: What tests do they include ✔✔ CORRECT ANSWER Spirometry Airflow
measurement
Lung volume Lung
capacity
4. Forced Vital Capacity (FVC): Amount of air that can be forcefully expelled from a maximally inflated
lung position.
5. What does a reduced forced vital capacity suggest ✔✔ CORRECT ANSWER Obstructive and restrictive pul-monary diseases.
6. Forced expiratory volume in 1 second (FEV1): Volume of air expelled during the first second of FVC
7. What are the findings of FEV1 in obstructive pulmonary disease ✔✔ CORRECT ANSWER Airways are narrowed
Resistance to flow is high
Numbers of FEV1 are less than predicted because not so much air can be expelled in 1 second.
8. FEV1: What are the findings in restrictive lung disease ✔✔ CORRECT ANSWER Decreased because amount of air originally
inhaled is low, instead of airway resistance.
9. What is a normal FEV1/FVC ratio in restrictive lung disease ✔✔ CORRECT ANSWER 80%.
10. What is a normal FEV1/FVC ratio in obstructive lung disease ✔✔ CORRECT ANSWER Less than 80%
11. Under what condition will the FEV1 value reliably improve ✔✔ CORRECT ANSWER With bronchodilator therapy
with a spastic component to obstructive pulmonary disease exists.
12. Normal results of Spirometry: Greater than 80% of expected value
13. Airflow rate: When is it considered diminished ✔✔ CORRECT ANSWER Less than 60% of normal.
, 14. What helps to increase airflow rate and by how much ✔✔ CORRECT ANSWER 20% by with bronchodilator
15. Diagnosis of COPD requires what ✔✔ CORRECT ANSWER Demonstration of persistent airflow limitation based on spirometry testing.
After bronchodilator, FEV1/FVC of less than 70%.
16. Classification of COPD severity is based on what ✔✔ CORRECT ANSWER Assessment of spirometry testing at regular
intervals
17. COPD Risk factors: Smoking Pollution
exposure
Genetic predispostion
18. How does COPD compare with asthma ✔✔ CORRECT ANSWER Onset later in life.
Slower progression of symptoms.
Poorer response to inhaled therapy.
19. Polysomnography: Sleep study
20. When is a polysomnography indicated ✔✔ CORRECT ANSWER When any person:
snores excessively
Experiences narcolepsy Excessive daytime
sleepiness Insomnia
Motor spasms while sleeping
Cardiac rhythm disturbances when sleeping.
21. What does a polysomnography test most commonly diagnose ✔✔ CORRECT ANSWER Sleep apnea
22. What is a actigraphy ✔✔ CORRECT ANSWER A watch that can be worn a few nights at home
23. What is a bronchoscopy used for ✔✔ CORRECT ANSWER Performing diagnostic and therapeutic procedures
24. What can you use a bronchoscopy for ✔✔ CORRECT ANSWER Visualization of a tracheobronchial tree Transbronchial
and Endobronchial biopsy
Bronchoalveolar lavage Removal of
foreign bodies Clots
Mucus plugs
Deployment of metallic stents. Aspiration of
deep sputum Bleeding control
