Written Lifeguarding Practice Test

After calling for EMS, the first step for an unresponsive victim with a complete airway obstruction is to perform 30 chest compressions. Giving ventilations or abdominal thrusts is not appropriate in this situation as the airway is completely obstructed and needs to be cleared before any other actions can be taken. Looking for a foreign object in the mouth should only be done after the airway has been opened and the victim is able to breathe. In this scenario, performing chest compressions is the most crucial step in trying to remove the obstruction and save the victim's life.
