13. You are performing CPR on the school librarian who has suffered a
cardiac arrest. She is unresponsive, you are alone, and you have already
phoned 911. She has no signs of injury and is not breathing, so you then
begin chest compressions. After your first set of compressions, you open
her airway, but her chest doesn't rise when you give rescue breaths. What
should you do?

You should redo the head tilt/chin lift to try and successfully open the airway.
Shout louder for help.
Run and get the AED.
* 5 poi
Go into your second set of compressions and hope that her airway opens better for
your next attempt at rescue breaths.
