A chest x-ray film obtained after intubation shows that the tip of
the ET tube is resting at the fourth rib. Which of the following
actions should be taken?
A. The tube should be advanced 2 cm
B. The tube should be advanced until equal breath sounds are
heard
C. The tube should remain at this level
D. The tube should be withdrawn 3 cm - correct answer-
D. The tube should be withdrawn 3 cm
A heated humidifier is delivering 100% body humidity to a
patient's airway. What volume of water is being delivered?
A. 24 mg/L
B. 37 mg/L
C. 44 mg/L
,D. 47 mg/L - correct answer- C. 44 mg/L
A patient breathing 50% oxygen has a PaO2 of 248 torr. Which
of the following should the RT recommend?
A. Discontinue O2 therapy
B. Decrease the oxygen to 30%
C. Titrate oxygen to maintain an SpO2 > 93%
D. Repeat the blood gases because the PaO2 is not possible on
this FiO2. - correct answer- C. Titrate oxygen to
maintain an SpO2 > 93%
Explanation: A PaO2 of 250 torr is normal on 50% O2.
Remember, to determine the normal PaO2 on any given O2%,
multiply the O2% by 5. This is an approximation. If titrate was
not a choice, then you would discontinue the oxygen.
A patient enters the emergency department, and on initial
examination the RT observes paradoxical chest movement.
Which of the following should the therapist suspect?

, B. Pneumonia
C. Flail chest

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withdrawn 4 cm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D. The tube is at the level of the carina and should be withdrawn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
A patient is experiencing cardiac arrhythmias and muscle
