How can chronic obstructive pulmonary disease (COPD) complicate upper respiratory disorders?

• A. It can enhance airflow through the nasal passages
• B. It can increase susceptibility to infections and exacerbate breathing difficulties
• C. It can completely eliminate respiratory symptoms
• D. It does not have any effect on upper respiratory disorders

Answer: (B)

The main idea is that COPD makes the respiratory system more vulnerable to infections and can worsen breathing when another upper airway illness occurs. In COPD, airflow is already limited by chronic inflammation and airway destruction, and mucociliary clearance is impaired, with increased mucus production. When an upper respiratory infection strikes, pathogens aren’t cleared as effectively, so infections are more likely to take hold, linger longer, and even spread to the lower airways. That combination often triggers COPD exacerbations, where breathing becomes noticeably harder, oxygen levels can drop, and the patient feels more short of breath. Nasal and sinus symptoms from an upper respiratory infection can add to the work of breathing and airway inflammation, further stressing an already compromised system. So the scenario most accurately describes increased susceptibility to infections and a worsening of breathing difficulties.

Choices that suggest enhanced nasal airflow, complete symptom elimination, or no effect don’t fit with COPD’s impact on airway function and immune defenses.
