Answer :
The given statement is true because When performing rescue breathing with a pocket mask, the rescuer uses the victim's chin as a guide to correctly position the mask.
The mask is placed over the victim's nose and mouth, and the rescuer creates a seal by pressing the mask against the victim's face with both hands. The rescuer then breathes into the mask while watching for the victim's chest to rise.
The use of a pocket mask is recommended in situations where mouth-to-mouth breathing may not be possible or desirable, such as during CPR or when there is a risk of infection or contamination. It is important to ensure that the mask is properly positioned and a good seal is achieved in order to effectively deliver rescue breaths.
