Check for responsiveness.

You are performing CPR on a victim and as assisting responder arrives. Which of following is most appropriate for the assisting responder to do first?

Check to see whether EMS personnel have been called.

When administering emergency oxygen to a victim, which of the following is most important to do?

Ensure oxygen is flowing through the device before putting it on the victim

To ensure high-quality CPR and high-quality chest compressions, you should:
