The physician has ordered O2 to be set up on a patient who has a spontaneous tidal
volume of 500 mL and an inspiratory time of 1 second. Which of the following O2
delivery devices will deliver a flow that meets or exceeds this patient's inspiratory
flow?
A. 35% air-entrainment mask at 6 L/min
B. 60% aerosol mask at 12 L/min
C. NRB mask at 15 L/min
D. Simple O2 mask at 10 L/min

500 mL = 0.5 L
0.5/1 = 0.5 L/s (change L/s to ?/min by multiplying by 60
0.5 L x 60= 30 L/min
Select the device that delivers a flow of at least 30L/min
A. 35% air-entrainment mask at 6 L/min
,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
3. Using a low-volume, high-pressure cuff
4. Using minimal occluding volume technique

The following blood gas levels have been obtained from a patient using a 60%
aerosol mask.
pH: 7.47
PaCO2: 31 mmHg
PaO2: 58 mmHg
What should the RT recommend at this time?
A. Place the patient on CPAP
B. Increase the O2 to 70%
C. Intubate and place the patient on mechanical ventilation
D. Change to a nonrebreathing mask

A. Place the patient on CPAP
While palpating the chest, the RT determines that there is decreased fremitus over the
right lower lobe. This may be the result of which of the following?

2. Pleural effusion
3. Pneumonia
