Sample AHA BLS Exam Questions and Answers 2022
Below are some sample questions that reflect the content and format of the AHA BLS exam, along with correct answers and explanations.
Question 1: What is the first step you should take when you encounter an unresponsive adult?
A. Check for breathing
B. Call for help
C. Begin chest compressions
D. Give rescue breaths
Answer: B. Call for help
Explanation: The first step in an emergency situation is to ensure that help is on the way. Calling for emergency medical services (EMS) allows for the quickest possible response, while assessing the patient's condition can follow.
Question 2: What is the correct compression-to-breath ratio for adult CPR when performing with a single rescuer?
A. 15:2
B. 30:2
C. 20:2
D. 25:2
Answer: B. 30:2
Explanation: The recommended ratio for adult CPR with one rescuer is 30 chest compressions followed by 2 rescue breaths. This pattern helps ensure that adequate blood flow is maintained while also providing oxygen to the lungs.
Question 3: When using an AED, what is the first step you should take after turning it on?
A. Attach the pads to the chest
B. Analyze the heart rhythm
C. Begin chest compressions
D. Call for help
Answer: A. Attach the pads to the chest
Explanation: The first step after turning on the AED is to attach the electrode pads to the patient’s bare chest. The AED will then guide the user through the next steps, including rhythm analysis and whether a shock is advised.
Question 4: How deep should chest compressions be for adults?
A. 1 inch
B. 2 inches
C. 3 inches
D. 4 inches
Answer: B. 2 inches
Explanation: For adults, chest compressions should be at least 2 inches deep but not more than 2.4 inches. This depth is necessary to create adequate blood flow during CPR.
Question 5: If you are alone and have a choking adult who is unresponsive, what should you do?
A. Call for help
B. Perform abdominal thrusts
C. Begin CPR
D. Wait for help
Answer: C. Begin CPR
Explanation: If the choking adult becomes unresponsive, you should begin CPR immediately. During the CPR process, you can check the airway for any obstructing objects and attempt to remove them if visible.
