Joe is a counselor at a summer camp for children ages 13 to 16. During an activity, one of the campers slipped and hit his head. Joe immediately checked for consciousness and found that the boy was not breathing. What should Joe do next? Call 911. Do compressions. Do compressions while calling 911. Do gentle rescue breathing while calling 911.

Call 911

Explanation:

In the best case scenario, Joe is not alone and is asking another counselor to call 911.  His shouting "call 911," would occur before starting chest compressions.  Only if he was alone, which is highly unlikely since he is a camp counselor and most likely is with another counselor for ratio purposes, would he be dialing 911 and put the phone down, while on speaker, at the same time as chest compressions.  In this case, he is still dialing 911 before starting chest compressions as you need 2 hands to do so.

is it multiple choice?
