A rescuer finds a victim unresponsive and not breathing normally. After calling 911, what is the NEXT priority according to the Chain of Survival?
Answer: Begin high-quality CPR immediately
After activating EMS, the rescuer should immediately begin CPR to maintain circulation until an AED is available.
Which of the following scenarios represents a WEAK link in the Chain of Survival?
Answer: An AED is available but no bystander knows how to use it
An AED that is present but not used represents a failure of the rapid defibrillation link, leaving a critical gap in the chain.
How does dispatcher-assisted CPR (DA-CPR) strengthen the Chain of Survival?
Answer: It guides untrained bystanders through CPR before EMS arrives, strengthening the early CPR link
DA-CPR allows 911 dispatchers to coach bystanders in real time, increasing the rate of bystander CPR even among untrained callers.
Which patient population benefits MOST from the in-hospital Chain of Survival's emphasis on surveillance and prevention?
Answer: Hospitalized patients showing early signs of deterioration before arrest occurs
Inpatient monitoring allows early recognition of deterioration, enabling intervention before cardiac arrest occurs.
Which of the following actions is LEAST consistent with strengthening the 'rapid defibrillation' link?
Answer: Storing AEDs in locked back rooms to prevent tampering
AEDs stored in inaccessible locations cannot be retrieved quickly, undermining the rapid defibrillation link.
After ROSC, a patient's blood pressure is 80/50 mmHg. Which component of post-cardiac arrest care addresses this?
Answer: Hemodynamic optimization with fluids and vasopressors
Hemodynamic optimization targets a mean arterial pressure ≥65 mmHg to ensure adequate organ perfusion after ROSC.
The Chain of Survival is best described as a:
Answer: Systems-of-care framework showing that survival depends on interdependent time-sensitive steps
The Chain of Survival is a systems framework applicable to both out-of-hospital and in-hospital cardiac arrest, involving community members, dispatchers, EMS, and hospital teams.
