The first step in the cardiac chain of survival is

• A. Call for help
• B. Early access
• C. Early CPR
• D. Early defibrillation

Answer: (B)

The main idea being tested is the importance of getting professional help on the scene as quickly as possible. Early access means rapidly activating the emergency response system so trained responders and equipment can reach the patient without delay. This step starts the chain of survival by ensuring that rapid assessment, defibrillation capability, and advanced life support are available as soon as possible. Without this quick mobilization, actions like CPR or defibrillation may be delayed, reducing the chances of survival and good neurological outcome. Once access is obtained, you can begin high-quality CPR and use a defibrillator as soon as it’s available, but the critical first move is to get responders moving toward the scene.
