Solution
The primary radiological sign of a tension pneumothorax on an X-ray is b. Mediastinal shift.
Here's why:
A tension pneumothorax occurs when air gets into the pleural space (the space between the lung and the chest wall) and cannot get out, causing the pressure in the pleural space to increase. This increased pressure can push the mediastinum (the central part of the chest that contains the heart, great vessels, and trachea) to the opposite side, a phenomenon known as a mediastinal shift.
This shift can be seen on an X-ray and is a key sign of a tension pneumothorax. Other options like Atelectasis, Pleural effusion, and Consolidation are signs of other lung conditions, not specifically tension pneumothorax.
