of water is being delivered?
A. 24 mg/L
B. 37 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. - ANS-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.

total flow delivered by this device is which of the following?
A. 36 L/min
B. 45 L/min
C. 54 L/min
D. 60 L/min - ANS-(*Use 21 with O2 % less than 40%)
(100- 30%)/ (30%-*21) = 70/9 = 8/1 or 8:1 ratio
8+1= 9
9x5 = 45 L/min
B. 45 L/min
A patient is receiving O2 from an E cylinder at 4 L/min through a nasal cannula. The
cylinder pressure is 1900 psig. How long will the cylinder run until it is empty?
A. 47 min
B. 1.7 h
C. 2.2 h
D. 3.6 h - ANS-E cylinder = 0.28
1900x0.28/4 = 133/60 = 2.21
