Question 1

1. The Cardiac Chain of Survival consists of a sequence of steps that are activated in response to an emergency in which a victim suffers sudden cardiac arrest. Each link in the chain is critical. Put the links in the Cardiac Chain of Survival in the correct order.

1) Early defibrillation — delivers electrical current to the heart with an automated external defibrillator (AED).
2) Early advanced life support — a team of professionals arrives and takes over by providing advanced care.
3) Early CPR — keeps oxygenated blood flowing.
4) Early recognition and early access — a bystander recognizes an emergency and calls 911 or the local emergency number.

A) 1, 3, 2, 4
