What is a late sign of tension pneumothorax?

1. Hypotension

2. Wheezing

3. Persistent cough

4. Skin rash

The correct answer is: Hypotension

Hypotension is considered a late sign of tension pneumothorax because it typically indicates a more severe and advanced state of the condition. In the early stages of tension pneumothorax, the body may compensate for decreased blood circulation due to lung collapse. However, as the pressure within the pleural space continues to build and compromises cardiac output, hypotension emerges. By the time a patient exhibits hypotension, the tension pneumothorax has likely progressed significantly, affecting both respiratory and cardiovascular function. This sign can signal a critical need for immediate intervention to relieve the pressure and restore normal physiology. Other potential symptoms like wheezing, persistent cough, or skin rash might occur with various conditions but are not definitive indicators of late-stage tension pneumothorax. Understanding these signs and their implications helps in prioritizing patient assessment and intervention in emergency situations.
