BLS Chain of Survival 4

Question 1

A rescuer finds a victim unresponsive and not breathing normally. After calling 911, what is the NEXT priority according to the Chain of Survival?

Accepted Answer

Begin high-quality CPR immediately

Answer

After activating EMS, the rescuer should immediately begin CPR to maintain circulation until an AED is available.

Question 2

Which of the following scenarios represents a WEAK link in the Chain of Survival?

Accepted Answer

An AED is available but no bystander knows how to use it

Answer

An AED that is present but not used represents a failure of the rapid defibrillation link, leaving a critical gap in the chain.

Question 3

How does dispatcher-assisted CPR (DA-CPR) strengthen the Chain of Survival?

Accepted Answer

It guides untrained bystanders through CPR before EMS arrives, strengthening the early CPR link

Answer

DA-CPR allows 911 dispatchers to coach bystanders in real time, increasing the rate of bystander CPR even among untrained callers.

Question 4

Which patient population benefits MOST from the in-hospital Chain of Survival's emphasis on surveillance and prevention?

Accepted Answer

Hospitalized patients showing early signs of deterioration before arrest occurs

Answer

Inpatient monitoring allows early recognition of deterioration, enabling intervention before cardiac arrest occurs.

Question 5

Which of the following actions is LEAST consistent with strengthening the 'rapid defibrillation' link?

Accepted Answer

Storing AEDs in locked back rooms to prevent tampering

Answer

AEDs stored in inaccessible locations cannot be retrieved quickly, undermining the rapid defibrillation link.
