This article aims to provide comprehensive insights into the 2020 BLS test answers, including tips for preparation, key concepts covered in the exam, and how to ensure you are up-to-date with the latest guidelines.
Overview of the 2020 AHA BLS Guidelines
Key Updates in 2020
The American Heart Association periodically revises its resuscitation guidelines based on the latest scientific evidence. The 2020 update introduced several important changes, including:
- Compression Depth and Rate: Continue pushing hard and fast, with a depth of at least 2 inches (5 cm) for adults and a rate of 100-120 compressions per minute.
- Rescue Breaths: For adult patients, rescue breaths should be delivered at a ratio of 30:2 when alone or as part of team CPR.
- Use of AEDs: Early defibrillation remains critical; AEDs should be used as soon as available.
- Team Dynamics: Emphasis on effective communication, role allocation, and minimizing interruptions during CPR.
- Post-Cardiac Arrest Care: Focus on post-resuscitation management, including targeted temperature management.
These updates are reflected in the test questions and answers, making it vital for test-takers to familiarize themselves with the latest standards.

2. Depth and Rate of Chest Compressions
Question: What is the minimum depth and recommended rate for chest compressions in adult CPR?
Answer:
- A) 1.5 inches at 100-120 compressions per minute
- B) 2 inches at 100-120 compressions per minute
- C) 2.5 inches at 80-100 compressions per minute
- D) 1 inch at 120-140 compressions per minute
Correct Answer: B) 2 inches at 100-120 compressions per minute
Explanation: High-quality CPR requires compressions at a minimum depth of 2 inches (5 cm) and a rate of 100-120 per minute.

3. Use of an AED in Cardiac Arrest
Question: When should an Automated External Defibrillator (AED) be applied during a cardiac arrest?
Answer:
- A) Only after performing CPR for 2 minutes
- B) As soon as it is available, as soon as the victim is unresponsive and not breathing normally
- C) Only if the victim is conscious
- D) After placing the victim on their side
Correct Answer: B) As soon as it is available, as soon as the victim is unresponsive and not breathing normally
Explanation: Early defibrillation with an AED is critical and should be performed as soon as the device is available and the victim shows no signs of normal breathing.
---
4. Recognizing and Managing Choking in Adults
Question: What is the recommended initial action for an adult choking victim who cannot cough or breathe?
Answer:
- A) Encourage them to cough harder
- B) Perform abdominal (Heimlich) compressions
- C) Give back blows only
- D) Call emergency services and wait for help
Correct Answer: B) Perform abdominal (Heimlich) compressions
Explanation: If an adult is choking and cannot cough or breathe, abdominal compressions (Heimlich maneuver) are recommended to expel the obstruction.
---
5. Post-Resuscitation Care Principles
Question: After restoring a pulse in a cardiac arrest patient, what is the priority in post-resuscitation care?
Answer:
- A) Rapid transport to the hospital without stabilizing the patient
- B) Maintaining adequate oxygenation and blood pressure, and preventing hypoxia and hypotension
- C) Discontinuing all medications and interventions
- D) Cooling the patient immediately to prevent brain damage
Correct Answer: B) Maintaining adequate oxygenation and blood pressure, and preventing hypoxia and hypotension
Explanation: Post-resuscitation care focuses on stabilizing the patient by supporting oxygenation, perfusion, and preventing secondary brain injury.
