Which of the following is the correct method of suctioning?

A. Suction intermittently, both while inserting and withdrawing the suction tip or catheter.

B. Begin suctioning as you insert the suction tip or catheter into the mouth.

C. Suction continuously, both while inserting and withdrawing the suction tip or catheter.

D. Insert the catheter or tip to the desired depth prior to applying suction.

The correct suctioning method is to insert the suction catheter to the desired depth before applying suction and then to suction intermittently while withdrawing the catheter.

Explanation:

The correct method of suctioning is to suction intermittently, which is best done during the withdrawal of the suction tip or catheter but not while inserting it. This process usually involves the following steps:

Wash your hands and wear appropriate protective equipment.
Pre-oxygenate the patient if necessary, to ensure they have enough oxygen during the procedure.
Insert the suction catheter without applying suction to avoid tissue damage; the catheter should be inserted to the desired depth.
Apply suction intermittently while withdrawing the catheter in a rotating motion to effectively clear the secretions.
Monitor the patient's condition throughout, and stop if they become distressed.
Rinse the catheter with saline solution if reusing, or dispose of it if it's for single use.

So, the correct answer to the question is D. Insert the catheter or tip to the desired depth prior to applying suction.
