Which condition can pleural effusion lead to?

• A. Compressive atelectasis
• B. Hyperinflation of the lungs
• C. Pneumonia
• D. Bronchoconstriction

Answer: (A)

Pleural effusion occurs when excess fluid accumulates in the pleural space surrounding the lungs, which can result in compressive atelectasis. This condition arises when the fluid buildup exerts pressure on the lung, compressing it and causing it to collapse partially or completely. As the lung is compressed, its ability to expand during inhalation is diminished, leading to reduced lung volumes and impaired gas exchange. In contrast, hyperinflation of the lungs generally refers to an increase in lung volume and is not typically associated with pleural effusion. Pneumonia is an inflammatory condition of the lung tissue that may occur independently but is not a direct result of pleural effusion. Bronchoconstriction involves tightening of the muscles around the airways, often seen in conditions like asthma, and is also not a consequence of pleural effusion. Therefore, the connection between pleural effusion and compressive atelectasis is crucial, as it highlights the direct impact of fluid accumulation on lung function.
