Correct answer: E — Treat as tension pneumothorax with immediate decompression and reassessment
Worsening hypoxia and shock with unilateral absent breath sounds after trauma is tension pneumothorax until proven otherwise. Decompression should not be delayed for ultrasound when severe compromise is present. Crystalloid does not address obstructive shock. The pearl is that reassessment after decompression is essential because haemothorax, tube failure or other injuries may coexist.
