    What is the proper technique for a nasal intubation?
    • A. 

      While the patient is sedated insert the tube into the left nose applying a firm pressure to rapidly insert the tube past the nares at a downward angle.

    • B. 

      Insert the tube at an upward angle in order to decrease the risk of bleeding, the nare should be pushed inferiorly

  • 8. 
    Why is it that adults need cuffed tubes and children do not?
    • A. 

      Children are less prone to tissue necrosis from large ETT tubes, adults need softer cuffs to prevent tissue necrosis.

    • B. 

      Pediatric cases are generally of a short duration, otherwise a cuffed tube would be used

      The much wider vocal cords of adults make extubation more likely so the cuff is used to prevent extubation.

    You are the SRNA for Mr. Becker today. During the middle of the ENT case the surgeon moves the patients head down, so that his chin is to his chest. Your preceptor asks how this will effect your ETT, what do you tell him?
    • A. 

      Aren’t YOU supposed to teach me this stuff?

    • B. 

      The ETT will be pulled upward and the pt is at risk for extubation.

    • C. 

      The ETT will be pushed further into the trachea, pt at risk for tube to hit carina or go into Right mainstem bronchus.

    • D. 

      The ETT should not move, you secured it prior to the procedure.
