Which statement is true regarding the use of a pocket mask for nonbreathing patients?

Using a pocket mask for non-breathing patients is a critical skill in emergency medical situations, and option C accurately reflects an important safety feature of the device. The one-way valve in the pocket mask allows air to flow from the rescuer into the patient while preventing exhaled air from the patient from entering the rescuer’s mouth. This minimizes the risk of potential contamination and protects the rescuer from exposure to any infectious agents.

The structure of the pocket mask is designed specifically for this purpose, making it a valuable tool during resuscitation efforts. It allows the rescuer to deliver positive pressure ventilation without compromising their safety, which is vital in emergency scenarios where quick and effective interventions are necessary.

Understanding this feature of the mask not only reinforces the importance of proper equipment use in emergencies but also highlights the protective measures that can be employed during patient care.
