What should be your main concern when assisting someone with a suspected head or neck injury?

When assisting someone with a suspected head or neck injury, the primary focus should be on avoiding any movement of the head or neck. This is crucial because any movement can exacerbate the injury, potentially leading to more severe consequences, such as spinal cord injury or further damage to the brain or neck structures. Keeping the injured person stable minimizes the risk of worsening their condition and provides the best chance for effective treatment once professional help arrives.

Other considerations, such as assessing for breathing difficulties or looking for signs of shock, are certainly important in a first aid scenario, but they come secondary to ensuring that the head and neck are kept immobile. Maintaining comfort could also be helpful, but the absolute priority in cases of suspected head or neck injuries is to prevent any additional harm through unnecessary movement.
