Question

The oropharyngeal airway device's advancing out of the mouth during ventilatory efforts

a. Indicates proper placement
b. May cause obstruction
c. Indicates the need for a larger size
d. Improves breathing efficiency

Answer 1

The oropharyngeal airway device moving out of the mouth during ventilation efforts may lead to obstruction, rather than indicating proper placement or improving breathing efficiency.

Step-by-step explanation:

If the oropharyngeal airway device advances out of the mouth during ventilatory efforts, this may cause obstruction rather than indicating proper placement. The correct size of an oropharyngeal airway should be such that it does not protrude excessively, nor should it be so small as to become ineffective at maintaining an open airway. A device that is moving outward could push the tongue or other tissues into the airway, thereby compromising ventilation and potentially causing further obstruction.
