Answer:
If an unconscious person is showing symptoms of shock, the first step is to call for emergency medical services (EMS) immediately. While waiting for EMS to arrive, lay the person down on their back and elevate their legs above the level of their heart, if possible. Loosen any tight clothing and cover them with a blanket to keep them warm. Do not give them anything to eat or drink, including water, and do not move them unless it is necessary to prevent further injury. It is important to monitor the person's breathing and pulse until help arrives.
