Written Lifeguarding Practice Test

Which of the following statements about bag-valve-mask resuscitators (BVMs) is most accurate?

1. BVMs are readily available at all emergency scenes.

2. Monitoring the victim for full exhalation is not required.

3. Ventilations are more effective when two rescuers operate the BVM.

4. When used by a single rescuer, BVMs allow easy coordination with chest compressions.

The correct answer is: BVMs are readily available at all emergency scenes.

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.
