Pathophysiology of COPD

Easy Physiological Adaptation Pathophysiology

A patient diagnosed with chronic obstructive pulmonary disease (COPD) is experiencing difficulty breathing and has a persistent cough. The nurse is aware that during exacerbations of this condition, the patient's oxygenation status may significantly decline due to increased airway resistance and altered lung mechanics.

Which of the following best explains the pathophysiological changes that occur in COPD?

Inflammation and narrowing of the airways, leading to airflow limitation.

Increased lung compliance, resulting in over-distention of alveoli.

Acute bronchoconstriction due to allergic reactions.

Excessive production of pulmonary surfactant, causing atelectasis.
