Answer Key: Can Exercise and Breathing Retraining Improve COPD Outcomes?
Answer Key:
1. True or False: Pursed-lip breathing helps prevent airway collapse during exhalation in patients with COPD.
Correct Answer: True
Pursed-lip breathing prolongs exhalation and creates a backpressure that helps keep airways open, preventing dynamic airway collapse—a common issue in COPD.

2. Which of the following is most closely associated with assessing functional exercise capacity in patients with COPD?
Correct Answer: C. Six-Minute Walk Distance (6MWD)
The 6MWD is a standard and practical measure of functional exercise capacity and endurance in patients with COPD, commonly used in both clinical and research settings.

3. True or False: Respiratory training has been shown to reverse structural damage in the lungs caused by COPD.
Correct Answer: False
While respiratory training can improve symptoms and exercise tolerance, it does not reverse the irreversible structural lung damage characteristic of COPD.
