Final answer:
Oropharyngeal airways should be used on unconscious and unresponsive patients.
Step-by-step explanation:
Oropharyngeal airways should be used on unconscious and unresponsive patients.
An oropharyngeal airway is a device used to maintain an open airway in patients who are unconscious or unable to maintain their own airway. It is inserted into the mouth and extends into the throat, helping to maintain the patency of the airway.
This device is not typically used on conscious and alert patients, pediatric patients only, or patients with respiratory allergies.
