Mastering the Correct Suctioning Technique: A Comprehensive Guide

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:

1. Wash your hands and wear appropriate protective equipment.

2. Pre-oxygenate the patient if necessary, to ensure they have enough oxygen during the procedure.

3. Insert the suction catheter without applying suction to avoid tissue damage; the catheter should be inserted to the desired depth.

4. Apply suction intermittently while withdrawing the catheter in a rotating motion to effectively clear the secretions.

5. Monitor the patient's condition throughout, and stop if they become distressed.

6. 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.
