A patient has just been intubated, and the CO2 detector placed on the proximal
end of the ETT reads 1.5%. The RT should suspect which of the following?
A. The tube is in the trachea
B. The tube is in the right mainstem bronchus and should be withdrawn 4 cm
C. The tube is in the esophagus
D. The tube is at the level of the carina and should be withdrawn 2 cm - correct-
answer -C. The tube is in the esophagus
Which of the following statements is true regarding the King Airway?
A. It is double-lumen tube placed in the esophagus to ventilate difficult-to-
intubate patients.
B. The airway can be used only on patients at least 5 feet tall
C. The airway utilizes one cuff, which is inflated with 45-90 mL of air to block off
the oropharynx
D. Because of the length of the airway, it is unlikely that the trachea can be
intubated inadvertently - correct-answer -D. Because of the length of the airway,
it is unlikely that the trachea can be intubated inadvertently
Magill forceps are used during which of the following procedures?
A. Nasotracheal intubation
, 2
B. Oral intubation
C. Tracheotomy
D. Insertion of an esophageal tracheal Combitube (ETC) - correct-answer -A.
Nasotracheal intubation
The physician wants to begin weaning a patient from a tracheostomy tube. How
can this best be accomplished?
A. Deflate the cuff every 2 hours
B. Change to a fenstrated trach tube
C. Keep the cuff inflated and remove the inner cannula
D. Change to a trach tube with a foam cuff - correct-answer -B. Change to a
fenstrated trach tube
You are called to a patient's room because a ventilator alarm is sounding. You
hear an audible leak around the patient's ET tube during a ventilator breath and
notice the exhaled volume reading is 150 mL less than the set Vt. You check the
cuff pressure and find that it is 12cm H2O. Which of the following is the
appropriate action to take?
A. Maintain the current cuff pressure and increase the patient's Vt to compensate
for the leak.
B. Instill enough air to maintain a cuff pressure of 30 mm Hg.
C. Instill air into the cuff to a pressure of 20-30 cm H2O.
D. Instill enough air until only a slight audible leak is heard. - correct-answer -C.
Instill air into the cuff to a pressure of 20-30 cm H2O.
You want to pass a suction catheter into the patient's left lung to obtain a sputum
specimen. What is the most appropriate method of accomplishing this?
A. Have the patient turn his or her head to the left
, 3
B. Have the patient turn his or her head to the right
C. Use a coude suction catheter
D. Use a catheter that is one half the internal diameter of the patient's airway -
correct-answer -C. Use a coude suction catheter
The RT is using a 12-French suction catheter to suction a female patient who is
intubated with a 7.0-mm ET tube and is having difficulty removing the thick
secretions. The suction pressure used is -120 mm Hg. Which of the following
should be recommended to correct this problem?
A. Increase the suction pressure to -140 mm Hg
B. Instill 5 mL of normal saline down the ET tube
C. Change to a 14 French suction catheter
D. Change to a coude-tipped suction catheter - correct-answer -A. Increase the
suction pressure to -140 mm Hg
The RT is called to pediatric ICU to suction a 6-year-old ventilator patient with
pneumonia who is intubated with a 5.0 mm ET tube. Which of the following
represents the most appropriate catheter size and suction pressure to use on this
patient?
A. 8-Fr catheter, -100mm Hg
B. 10-Fr catheter, -60mm Hg
C. 8-Fr catheter, -60mm Hg
D. 10-Fr catheter, -100mm Hg - correct-answer -A. 8-Fr catheter, -100mm Hg
Which of the following will increase the possibility of the ET tube cuff causing
tracheal mucosa damage?
1. Maintaining intracuff pressure of 38 cm H2O
2. Using minimal leak technique
