Written Lifeguarding Practice Test

BVMs are devices used to provide artificial ventilation to a person who is not breathing. Option A is the most accurate statement because BVMs are often readily available at most emergency scenes, both in professional settings and in public places. This is because BVMs are a critical tool in administering life-saving care in emergency situations. Option B is incorrect because it is important to monitor the victim for full exhalation during BVM use to ensure proper ventilation and avoid complications. Option C is incorrect because while two rescuers may operate a BVM more effectively, a single rescuer is still able to provide effective ventilation. Option D is incorrect because when used by a single rescuer, coordination with chest compressions can be challenging and is not as easy as with a two-person team.
