The correct answer is "check to see if they are responsive".if you encounter a child or an adult, which is pale and people seem to think that they are not breathing, the first thing you do is check if he or she is not responsive, afterwards call an ambulance immediately or rush the child or adult towards the emergency room in the hospital to be treated.
