Question

which of the following conditions may result in a collapsed lung? a pulmonary embolism b tuberculosis c pleural effusion d pneumothorax

Explanation:

Pneumothorax is a condition where air enters the space between the lung and the chest wall, causing the lung to collapse. Pulmonary embolism is a blockage in a lung artery, tuberculosis is an infectious disease affecting the lungs, and pleural effusion is the accumulation of fluid in the pleural space. None of these directly cause a collapsed lung in the same way pneumothorax does.

Answer:

D. pneumothorax
