Final answer:
The first aider should avoid moving the victim's head and neck, lift the chin without tilting the head, and provide air. All of the above precautions are correct and should be taken together when a victim is suspected to have a head, neck, or back injury.
Step-by-step explanation:
When giving rescue breathing and there is a suspicion that the victim has a head, neck, or back injury, the first aider should try not to move the victim's head and neck, try to lift the chin without tilting the head, and remember that the non-breathing victim's greatest need is for air. All of these actions are correct because they aim to open the airway in a way that minimizes the risk of further injury to the spinal cord, which could result in permanent paralysis or other serious complications. It is critical to provide the necessary air to the victim without exacerbating any potential spinal injuries. If the victim is not breathing, CPR should be administered following the proper protocols, emphasizing chest compressions and avoiding unnecessary movement of the head or neck. If an emergency arises where CPR is necessary, it should be performed with caution for the mentioned injuries until emergency medical professionals arrive on the scene.
In summary, all the above-stated precautions should be taken into consideration while attempting to provide rescue breathing to ensure the safety and recovery of the victim.
