Basic Life Support (BLS) Practice Exam

What is the first step you should take if Mrs. Clark becomes unresponsive?

1. Start chest compressions immediately

2. Check for a pulse

3. Carefully lower her to a firm, flat surface and begin CPR

4. Call for assistance

The correct answer is: Carefully lower her to a firm, flat surface and begin CPR

The first step when encountering an unresponsive individual is to ensure their safety and to provide an appropriate environment for administering CPR. Carefully lowering Mrs. Clark to a firm, flat surface is essential because it allows you to effectively perform chest compressions and rescue breaths with the correct technique. CPR should be performed on a hard, flat surface to maximize the effectiveness of the chest compressions. Once she is on a firm surface, you can then start CPR, which includes both chest compressions and rescue breaths if trained to do so. Ensuring that the person is on an appropriate surface is critical before engaging in any further lifesaving actions. Although checking for a pulse or calling for assistance may be actions taken after ensuring the scene and patient are safe, they are not the immediate priority response in this situation. The emphasis is on promptly preparing to provide CPR, as time is of the essence when dealing with an unresponsive patient.
