Which presentation is most typical of a hemothorax?

• A. Tracheal deviation with dull percussion and signs of hypovolemia
• B. Bilateral basilar crackles with normal vitals
• C. Hyperresonant chest with decreased breath sounds
• D. Clear chest with no distress

Answer: (A)

Hemothorax involves blood collecting in the pleural space. When the bleed is significant, the fluid (blood) dulls percussion over the affected side and reduces breath sounds because the lung is compressed. If enough blood accumulates, it can push the mediastinal structures and cause the trachea to deviate away from the injured side. The ongoing loss of blood also leads to signs of hypovolemia, such as tachycardia and potential hypotension. So a presentation with tracheal deviation, dull percussion, and signs of hypovolemia fits a sizable hemothorax best.

The other patterns don’t fit as well: bilateral basilar crackles with normal vitals point more to edema or infection; a hyperresonant chest with decreased breath sounds suggests pneumothorax; a clear chest with no distress isn’t consistent with a pleural bleed.
