                Correct answer:
                
                    Apply firm pressure to the wound
                
             
        
            
                Explanation
            
            
                Before helping the pedestrian, you should protect yourself from contact with blood. If there's nothing embedded in the wound, you can stem the flow of blood by applying pressure to the wound area. As soon as practical, fasten a pad to the wound with a bandage or cloth.
