Which combination of signs indicates a chest wall injury after blunt trauma?

• A. Localized chest wall pain or tenderness, guarding, difficult breathing.
• B. Pain in the lower back with leg weakness.
• C. Abdominal cramps after eating.
• D. Headache and blurred vision.

Answer: (A)

Blunt chest trauma that injures the chest wall typically shows localized tenderness over the ribs, guarding of the chest, and trouble breathing. These signs point to a chest wall injury like a rib fracture or contusion because they involve the chest itself and affect ventilation—pain and guarding limit deep breaths, leading to dyspnea. Other options describe problems in different areas (back/spine, abdomen, or head) and don’t reflect chest wall injury, so they don’t fit with blunt chest trauma.
