What is the first step after placing an oropharyngeal airway (OPA) in a patient?

The correct answer being confirmed involves checking for proper placement and an adequate seal after placing an oropharyngeal airway (OPA). This is crucial because proper placement ensures that the airway is positioned correctly within the oropharynx, which allows for effective ventilation and prevents the airway from becoming obstructed. Checking for an adequate seal is also essential; a good seal ensures that air flows through the airway and into the lungs rather than escaping around the OPA, which could lead to inadequate ventilation.

Confirming proper placement typically involves visual inspection and manual examination, ensuring that the airway is not causing additional obstruction, such as by pushing the tongue back further into the throat. An improper placement can lead to complications, including airway compromise or failure to ventilate adequately.

In contrast, while assessing vital signs or administering supplemental oxygen are important steps in airway management, they occur after confirming that the OPA is in place correctly and functioning properly. Ensuring that the airway is patent and the OPA is effective is the immediate priority in a situation where respiratory support is needed.
