Question

how do you open the airway for breaths if a single rescuer is present?
choose the correct answer
head tilt - chin lift
oropharyngeal airway
tongue blade
nasopharyngeal airway

Explanation:

The head - tilt chin - lift is a fundamental and commonly used method for a single rescuer to open the airway. It is a non - invasive and straightforward technique. Oropharyngeal and nasopharyngeal airways are more invasive and usually require additional equipment and more advanced training. A tongue blade is mainly used for visualizing the oral cavity rather than primarily for opening the airway for breaths in a basic resuscitation scenario.

Answer:

Head tilt−chin lift
