Final answer:
The correct device for a nurse to use when suctioning a client's oral airway is the Yankauer suction tip, as it is designed for clearing secretions from the mouth and throat. The correct option is A.
Explanation:
A nurse preparing to suction a client's oral airway should use a Yankauer suction tip. This device is specifically designed for oral suctioning and is commonly used to clear the mouth and throat of saliva, blood, or other secretions, ensuring that the airway remains clear. Unlike the other options, the Yankauer suction tip is not for establishing an airway but rather for keeping an existing airway clear from obstructions.
