attach a secondary confirmation device, such as an end-tidal CO2 detector.

secure the tube in place with a commercial device.
D.
leave the stylet in place until tube placement is verified.

fit under the epiglottis and directly expose the vocal cords.
D.
lift the uvula and bring the vocal cords into clear view.

4.5 mm
D.
5.0 mm
12.
When an ETT is properly positioned, the cuff should be situated:
A.
at the carina.
B.
at the nasopharynx.
C.
just passed the vocal cords.
D.
halfway between the nasopharynx and the vocal cords.
13.
Insertion of an ETT should take:
A.
no more than 10 seconds.
B.
30 seconds or less.
C.
45 to 60 seconds.
D.
1 to 2 minutes.
14.
Which of the following would be considered a lethal complication of endotracheal intubation?
A.
intubating the esophagus and not recognizing it
B.
accidentally chipping the patient's two front teeth
C.
hyperextending the cervical spine of a nontrauma patient
D.
ventilating without giving the patient supplemental oxygen
15.
When attempting oral intubation on a patient with a suspected spinal injury, it is important to:
A.
use an ETT one size larger than normal.
B.
inflate the cuff with an extra 15 mL of air.
C.
maintain manual spinal immobilization.
