A patient is receiving O2 from an E E cylinder = 0.28
cylinder at 4 L/min through a nasal 1900x0.28/4 = 133/60 = 2.21
cannula. The cylinder pressure is
1900 psig. How long will the Answer: C. 2 hours, 21 minutes
cylinder run until it is empty?
A. 47 min
B. 1.7 h
C. 2.2 h
D. 3.6 h
,After the Respiratory Therapist sets D. Increase the flow rate to 15 L/min
up a nonrebreathing mask on a
patient at a flow rate of 10 L/min,
the reservoir bag collapses before
the patient finishes inspiring. The RT
should do which of the following?
A. Change to a simple mask at a
flow rate of 10 L/min
B. Remove the one-way valve from
the exhalation port.
C. Place the patient on continuous
positive airway pressure (CPAP)
D. Increase the flow rate to 15 L/min
A patient with carbon monoxide D. Nonrebreathing mask
(CO) poisoning can best be treated
with which of the following
therapies?
A. Nasal Cannula at 6 L/min
B. Simple O2 mask at 10 L/min
C. CPAP and 60% O2
D. Nonrebreathing mask
, The following blood gas levels A. Place the patient on CPAP
have been obtained from a patient
using a 60% aerosol mask.
pH: 7.47

What should the RT recommend at
this time?
A. Place the patient on CPAP
