Answer :
Final answer:
The nurse demonstrates understanding of endotracheal suctioning process by acknowledging the need to wait 30 seconds between suctions and limit the procedure to 4 passes. Suction should not be applied during catheter insertion and saline should not be used for lubrication.
Explanation:
The question is about the procedure for endotracheal suctioning, specifically the comprehension of the newly licensed nurse. The statement that indicates an understanding of the teaching is: 'I should wait 30 seconds between each suction pass.' This is because it's crucial to permit adequate oxygenation between suctioning passes. Rapid, consecutive suctioning may lead to hypoxemia or low levels of oxygen in the blood. 'I will repeat the suction procedure for up to 4 suction passes' is also correct because generally, a limit of 3-4 suctioning passes is advised to minimize the potential for harm. 'I should apply sterile saline to lubricate the suction catheter' is incorrect as sterile saline should not be used to lubricate but to remove secretions if needed. Also, 'I will apply suction for 10 seconds as I insert the catheter' is incorrect as suction should be applied while withdrawing not inserting the catheter.
