Which procedure should be performed if the patient is unconscious?

When a patient is unconscious, the priority must be to ensure their safety and address any potential life-threatening conditions. Activating Emergency Medical Services (EMS) is critical, as professionals can provide the necessary advanced care. Preparing for CPR is also essential, as unconsciousness can indicate a compromised airway or lack of breathing. Initiating CPR immediately may be lifesaving if the patient is not breathing or has no pulse.

In this scenario, providing food and water is inappropriate because an unconscious person cannot swallow safely, which poses a risk of choking or aspiration. Encouraging someone who is unconscious to walk around is dangerous and infeasible, as they are unable to respond to commands or stabilize themselves. Ignoring an unconscious individual is entirely unsafe, as they require immediate assessment and assistance to prevent potentially serious outcomes. Therefore, activating EMS and preparing for CPR is the most responsible and life-saving action to take in this situation.
