Final answer:
In scenario 1, move the person to stable ground before starting CPR. In scenario 2, call emergency services and perform CPR, using an AED if available. In scenario 3, call emergency services, ensure safety, assess responsiveness, and provide CPR if necessary.
Step-by-step explanation:
In scenario 1, the person appears to have collapsed/slid down the wall into the shape of a ball on the ground. The first priority in this situation is to check for responsiveness and call emergency services. If the person is unresponsive, it is important to perform CPR by starting chest compressions. However, before beginning CPR, it is crucial to move the person to stable ground away from the wall to ensure effective resuscitation.
In scenario 2, the person's skin turning blue indicates a lack of oxygen, suggesting a potential cardiac arrest. The immediate response should be to call emergency services and to start CPR. Additionally, an automated external defibrillator (AED) should be located and used if available.
In scenario 3, the presence of facial lacerations and bent arms in the adults and children indicate potential injuries from a car accident. The first step is to call emergency services and ensure the safety of the environment, checking for any hazards. Afterward, assess each individual's responsiveness and provide CPR if needed, while also considering the potential presence of spinal injuries.
