Regarding suctioning the adult oropharynx, which statement best describes the recommended technique?

• A. Suctioning should occur while advancing the catheter toward the carina.
• B. Suctioning should be performed for only 5 seconds at a time.
• C. Suctioning should be performed while withdrawing the catheter from the oropharynx.
• D. Suctioning should be avoided in all unconscious patients.

Answer: (C)

The technique tested focuses on clearing the upper airway without pushing secretions into the deeper lungs. The correct approach is to insert the suction catheter into the mouth and then suction while withdrawing the catheter from the oropharynx. Doing this pulls secretions out as you pull back, rather than pushing them downward toward the carina, which could lead to aspiration or bronchial irritation. It also helps protect the airway from trauma and reduces the chance of triggering a gag or coughing response in many patients.

In practice, keep the catheter in the oropharynx and avoid advancing toward the lower airway, and limit suction passes to a short duration (about 10 seconds or less) with oxygenation as needed before and after. This combination minimizes hypoxia and keeps the procedure safer for an adult patient.
