You arrive at a scene where a patient's head is flexed forward and she does not appear to be breathing. What is your immediate concern?

In this scenario, the immediate concern revolves around the safety of the rescuers. When approaching a scene where a patient is unresponsive and not breathing, it is critical to first assess the environment to ensure that it is safe for both the rescuers and the patient. Any potential hazards—such as traffic, fire, or even unstable surfaces—must be identified and mitigated to prevent further injury to yourself or others.

Once the area is deemed safe, rescuers can then proceed to provide care to the patient. If there are immediate threats present in the environment, taking necessary precautions is essential before any clinical intervention can take place. Safety is the priority to ensure that rescuers can assist the patient effectively and without compromise to their own well-being or that of bystanders.

Other concerns like calling for additional help, administering CPR, or determining the cause of the incident are important aspects of emergency care, but they cannot be initiated until the scene is secure, making safety the foremost priority.
