What term describes a blunt-trauma chest injury that damages internal organs and/or causes internal bleeding?

• A. Color Vision
• B. Closed Soft Tissue Injuries
• C. Complex Motor Skills
• D. Closed Chest Injury

Answer: (D)

Blunt-trauma to the chest that can harm internal organs or cause internal bleeding is described as a closed chest injury. The term “closed” means the chest wall and skin aren’t pierced, even though internal structures like the heart or lungs may be damaged. This distinguishes it from open or penetrating chest injuries, where a wound penetrates the chest wall. The other options don’t fit: color vision is unrelated to chest trauma, closed soft tissue injuries aren’t specific to the chest or internal organ damage, and complex motor skills pertain to neuromuscular function, not injury terminology.
