A 50-year-old male presents with hypotension, hypoxemia, and tracheal deviation to the left. Tests reveal that the air pressure in the pleural cavity exceeds barometric pressure in the atmosphere. The most likely diagnosis is:
A) pleural effusion.
B) tension pneumothorax.
C) open pneumothorax.
D) transudative pneumothorax.

Question

Quizplus · Accepted Answer

The presentation of hypotension, hypoxemia, and tracheal deviation to the left along with high pressure in the pleural cavity exceeding barometric pressure in the atmosphere suggests tension pneumothorax. With this condition, air accumulates in the pleural space and creates pressure, which can push the heart and other thoracic structures to the opposite side of the affected lung, causing tracheal deviation. This can lead to hypotension and hypoxemia and is a medical emergency requiring prompt treatment. Options A, C, and D are not consistent with the presentation and test results provided.
