What does pleural effusion refer to?

1. Fluid in pleural space

2. Air in the pleural space

3. Pneumonitis

4. Collapsed lung

The correct answer is: Fluid in pleural space

Pleural effusion specifically refers to the accumulation of fluid in the pleural space, which is the thin cavity between the layers of tissue lining the lungs and the chest wall. This condition can occur as a result of various underlying diseases or conditions such as heart failure, infections, malignancies, or trauma. The presence of excess fluid can lead to respiratory symptoms and reduced lung function, making it a significant concern in oncology patients due to the potential impact on their respiratory health. Fluid accumulation in the pleural space can be identified and evaluated through imaging techniques such as ultrasound or chest X-ray, and management may involve therapeutic procedures like thoracentesis to relieve symptoms or further investigate the nature of the fluid. Understanding pleural effusion is crucial for oncology nurses as it is often associated with cancer-related complications, necessitating careful monitoring and management strategies.
