Written Lifeguarding Practice Test

To ensure high-quality CPR and high-quality chest compressions, you should:

1. Compress the victim's chest to a shallow depth

2. Expose the victim's chest to ensure proper hand placement and full chest recoil

3. Keep your shoulders directly over your hands and bend your elbows

4. Place the victim on a soft, flat surface

The correct answer is: Compress the victim's chest to a shallow depth

Performing CPR is an important life-saving skill, and it's essential to know how to perform it correctly. Option A is the correct answer, as compressing the victim's chest to a shallow depth can help maintain good blood flow to the heart and brain, ensuring high-quality CPR. Option B is incorrect because exposing the victim's chest is a necessary step in preparing for CPR, but it is not related to the quality of CPR itself. Full chest recoil is also important, but it is not the primary focus of high-quality compressions. Option C is incorrect because keeping your shoulders directly over your hands and bending your elbows is a technique used for proper hand placement and effective compressions, but it does not ensure high-quality CPR on its own. Option D is incorrect because placing the victim on a soft, flat surface is a precautionary measure to ensure their comfort and safety during CPR, but it does not directly contribute to high-quality CPR.
