What should you do if a person is responsive and fully awake while waiting for EMS?

The best course of action for a responsive and fully awake individual while waiting for EMS is to monitor their condition carefully. The most appropriate response would be to continuously check their breathing, ensuring they remain stable until professional help arrives. This option allows you to be attentive to any changes in their condition, as they may require immediate assistance if their situation worsens.

Maintaining a vigilant watch over their breathing can be crucial, as it helps identify if they become less responsive or if their airway becomes compromised. Placing them in a recovery position is indeed beneficial for someone who is unconscious but breathing normally, as it aids in keeping the airway clear and prevents choking. However, if they are fully responsive and awake, it is more important to monitor their status and be prepared to act if necessary.

Administering CPR is not appropriate for someone who is responsive and actively breathing, as this intervention is intended for individuals who are unresponsive and not breathing. Offering food or drink could be dangerous if there is any risk of choking, especially if the person's condition changes while you're waiting for EMS. Therefore, keeping a close watch on their breathing is a prudent choice.
