What should be done until EMS personnel arrive for a guest with a spinal injury?

Maintaining the guest's current position is critical in the case of a spinal injury. This approach helps to minimize any potential damage to the spinal cord by preventing movement that could exacerbate the injury. Moving someone with a spinal injury can lead to paralysis or other serious complications, so keeping them still is essential until Emergency Medical Services (EMS) personnel arrive. They are trained to handle such situations and will know how to safely transport the individual without risking further injury.

Monitoring the victim's breathing is important, but it does not involve repositioning them. Keeping the person talking can be beneficial in assessing their consciousness, but it should not come at the cost of their stability. Providing them with water is not advisable, as this could pose a choking hazard or cause complications if they need medical intervention. Therefore, maintaining their current position is the most appropriate action in this scenario.
