Answer :
Final answer:
The maximum time for suctioning the oral cavity is 15 seconds, and suction should be performed on the way out. This approach minimizes tissue trauma and effectively removes secretions, similar to the process of sucking liquid through a straw by creating a negative pressure. The correct option is c.
Explanation:
The question regarding the maximum amount of time you can suction the oral cavity of a patient and whether you should suction on the way in or on the way out is focused on a critical aspect of patient care. The correct answer is c) 15 seconds, on the way out. It is important to limit suctioning to 15 seconds as prolonged suctioning can cause hypoxia, which is a condition resulting from insufficient oxygen reaching tissues. Additionally, suctioning on the way out is the correct technique as it minimizes the risk of tissue trauma and allows for the removal of secretions more effectively. This technique leverages the principle of creating a negative pressure environment, similar to how liquid flows into your mouth when you suck on a straw and close off the external air, increasing the volume inside your mouth and lowering the internal pressure.
