Advanced Cardiovascular Life Support (ACLS) Practice Exam

What is the recommended sequence of actions in the adult Chain of Survival?

1. EMS activation, CPR, defibrillation, advanced life support, post-arrest care

2. CPR, defibrillation, advanced life support, EMS activation, post-arrest care

3. Defibrillation, advanced life support, CPR, EMS activation, post-arrest care

4. EMS activation, defibrillation, CPR, post-arrest care, advanced life support

The correct answer is: EMS activation, CPR, defibrillation, advanced life support, post-arrest care

The recommended sequence of actions in the adult Chain of Survival emphasizes the importance of quick and effective response to a cardiac emergency. In this sequence, the first step is the activation of emergency medical services (EMS). This ensures that advanced medical care is on the way as soon as possible. Prompt EMS activation is critical because it allows for a rapid escalation of care beyond what can be provided at the scene. Following EMS activation, the next essential action is performing high-quality cardiopulmonary resuscitation (CPR). CPR is vital for maintaining blood flow to vital organs until advanced interventions can be administered. Early CPR significantly increases the chances of survival and favorable outcomes. Defibrillation comes next in the sequence. Rapid defibrillation is crucial when a victim is in a shockable rhythm, such as ventricular fibrillation or pulseless ventricular tachycardia. The sooner defibrillation is delivered after the onset of cardiac arrest, the better the chances of restoring a normal heart rhythm. After defibrillation, the next focus is on advanced life support, which involves a team of healthcare providers administering medications and other advanced interventions aimed at stabilizing the patient’s condition. The final aspect of the Chain of Survival is post-arrest care, which addresses the comprehensive
