Which symptom is associated with chest trauma as listed?

• A. Blood-tinged sputum
• B. Clear urine
• C. No chest symptoms
• D. Normal heart rate

Answer: (A)

In chest trauma, signs of bleeding within the airway point to lung or airway injury. Blood-tinged sputum happens when blood from injured lung tissue or airways is coughed up, which can occur with pulmonary contusion, airway laceration, rib fractures that involve the lung, or associated pneumothorax/hemothorax. This symptom directly reflects thoracic injury and lungs, making it the most consistent choice among the options.

Other signs like clear urine, no chest symptoms, or a normal heart rate don’t indicate chest trauma. Urine clarity has no relation to chest injuries, claiming no chest symptoms would contradict the presence of thoracic injury, and while a normal heart rate can occur, it doesn’t provide evidence of chest trauma.
