What is a primary symptom of emphysema described in the material?

• A. Severe shortness of breath
• B. Headache
• C. Rash
• D. Fever

Answer: (A)

Shortness of breath is the defining symptom because emphysema damages the tiny airways and alveolar walls, reducing elastic recoil and causing air trapping. This makes exhaling inefficient and breathing laborious, so exertional dyspnea becomes the most prominent feature as the disease progresses. Headache, rash, and fever are not typical primary manifestations of emphysema; they point to other issues such as headaches from different causes, skin or systemic inflammatory conditions, or infections, rather than the chronic airflow limitation seen in emphysema.
