Upon discovering a client unresponsive on the floor, what should the psychiatric technician do next after calling for help?

In the scenario where a client is found unresponsive, immediately assessing the airway is crucial, which is why tilting the head backward is the correct action. This maneuver helps to open up the airway by preventing the tongue from obstructing it, which is often the case when a person is unresponsive.

Once the airway is clear, the psychiatric technician can then assess for breathing and circulation, which are essential to determine the appropriate next steps, such as CPR or recovery position. It's important to act quickly and efficiently to ensure the patient's safety while waiting for additional medical assistance to arrive.

Ensuring an open airway is a fundamental step in emergency medical response, laying the groundwork for further assessment and intervention.
