Tenderness is a common sign of internal bleeding because it indicates irritation or damage to tissues and organs as blood collects within the body. When internal bleeding occurs, blood can seep into areas where it normally wouldn't be present, leading to inflammation and pressure on surrounding tissues. This often results in a person experiencing tenderness or pain in the affected area, as the body's protective response activates to signal that something is wrong.

In contrast, the other choices do not typically indicate internal bleeding. Red, dry skin may suggest dehydration or other skin conditions rather than internal issues. Open blisters are usually associated with burns or friction rather than bleeding, and cool, dry skin can indicate shock or low blood flow but does not directly signify internal bleeding alone. Thus, tenderness stands out as a clear and relevant sign of potential internal bleeding.
