What is a common immediate action in the treatment of pneumothorax?

• A. Seek medical attention immediately
• B. Administer 100% oxygen and monitor at home
• C. Wait and see if it resolves
• D. Apply chest compressions

Answer: (A)

The main idea here is that a pneumothorax can worsen quickly and requires urgent professional evaluation. When air leaks into the space around the lung, the lung may collapse and, if it progresses to a tension pneumothorax, can compress the heart and great vessels—an emergency situation. The most important immediate action is to seek medical attention right away so clinicians can assess severity, perform any necessary imaging, and provide definitive treatment (such as needle decompression if a tension pneumothorax is present or a chest tube for a larger leak).

Giving high-flow oxygen during transport can help the body resorb the air, and staying calm with minimal activity is sensible, but these steps do not replace urgent medical care. Waiting to see if it resolves or trying to manage at home isn’t appropriate, and chest compressions are used for cardiac arrest, not pneumothorax.
