Which of the following is a symptom of emphysema?

Wheezing is a common symptom associated with emphysema, a form of chronic obstructive pulmonary disease (COPD). In emphysema, the alveoli in the lungs become damaged and lose their elasticity, leading to difficulty in exhaling air. This can cause air to get trapped in the lungs, resulting in the narrowing of the airways and turbulent airflow, which can produce a wheezing sound during breathing.

In contrast, severe vomiting, persistent fever, and joint pain are not symptoms associated with emphysema. Severe vomiting may point toward gastrointestinal issues or infections, a persistent fever could indicate an infection or systemic illness, and joint pain relates more to musculoskeletal disorders rather than pulmonary conditions. Therefore, wheezing stands out as a direct respiratory symptom indicative of the airway obstruction typically seen in emphysema patients.
