Which of the following best describes signs of a hemothorax?

Blood in the pleural space after chest trauma causes the affected lung to collapse or fail to expand fully, so you hear decreased or absent breath sounds on that side and the area often feels dull on percussion. If the bleeding is significant, the patient can go into shock from intrathoracic blood loss, even when there’s no external injury. That combination—diminished breath sounds on the injured side with signs of shock and no external bleeding—is classic for a hemothorax. In contrast, a hyperresonant percussion note points toward air in the pleural space (pneumothorax), not blood. Clear breath sounds with stable vitals wouldn’t fit an intrathoracic bleeding scenario, and an audible wheeze bilaterally suggests airway reactivity or obstruction rather than blood in the chest.
