Which of the following most accurately describes the finding of jugular venous distension in pneumothorax?
  1. It is an early finding of even minor pneumothoraxes
  2. It indicates relative hypovolemia in the thorax due to hemorrhage
  3. It is indicative of high intrathoracic pressure
  4. Pneumothorax is more likely to cause jugular vein flattening
Explanation
Answer: C - JVD is typically a sign of increased intrathoracic pressure, but can be a very late finding.

It presents when increased pressure on the great vessels in the thorax cause a backup of blood returning from the head. This typically presents in serious tension pneumothoraxes and does not appear in minor cases.
