Areya is taking CPR lessons. She uses a dummy to practice what she has learned. Areya checked the dummy for consciousness, called 911, and started to do 60 chest compressions per minute. Her trainer stopped Areya's demonstration to correct her. What did the trainer most likely say to Areya? "Call 911 before doing anything else." "Bend his knees and lift his legs." "Do 100 to 120 compressions per minute." "Perform the Heimlich maneuver."
