------------------------------------------------ Which of the following statements regarding suctioning of an adult is true?

1) You should insert the suction catheter only as far as you can visualize.
2) You should start ventilations if suction cannot clear the airway.
3) You should only suction for a maximum of 30 seconds.
4) You should remove the suction catheter with the suction machine turned off.

The true statement about suctioning in an adult is that suction should be applied for no longer than 30 seconds. Additionally, the catheter should be removed while the suction is still active.

Explanation:

The correct statement regarding the suctioning of an adult is that C) you should only suction for a maximum of 30 seconds. When suctioning an airway, it is important to prevent hypoxia, therefore the suction should not last longer than necessary to clear the airway obstruction and should be as brief as possible, generally advised not to exceed 30 seconds. Additionally, it is recommended to remove the suction catheter with the suction machine turned on to ensure that any debris or secretions are cleared as the catheter is removed. This helps to prevent re-introducing the material back into the airway.
