The physician orders a 35% aerosol mask to be set up for
a patient who requires an inspiratory flow of 42 L/min.
What is the minimum flow rate to which the flowmeter
must be set to meet this patient's in- spiratory flow
demands?
A. 6 L/min
B. 8 L/min
C. 10 L/min
D. 12 L/min - Answer-B, The air/O2ratio for a 35% oxygen
mixture is 5 : 1. To calculate total flow output from this
device, add the ratio parts together and multiply by the liter
flow: 6 ×6 = 36 L/min, 6 ×8 = 48 L/min, 6 × 10 = 60 L/min,
6 ×12 = 72 L/min. Total flow needed: 42 L/min. The
minimum flow necessary is 8, giving a total flow of 48
L/min. (Analysis)
A premature 3-week-old infant is receiving 1 L/min
of O via a nasal cannula and has a PaO of 43 torr22

and a PaCO2 of 40 torr. The respiratory therapist should
recommend which of the following?
A. Increase the cannula flow to 2 L/min.
B. Intubate and institute mechanical ventilation
C. Initiate CPAP of 4 cm H2O and 50% O2
D. Increase the cannula flow to 5 L/min. - Answer-A, A
PaO2 of 43 torr represents hypoxemia. The normal PaO2
for an infant is 50-70 torr. Increasing the cannula flow by 1
L/min is the most appropriate choice to return the PaO2 to
normal. With a normal PaCO2 of 40 torr, mechanical
ventilation is not indicated. (Analysis)
what is normal PaO2 for infant ? - Answer-50-70 torr.
A patient arrives in the emergency department after being
pulled from a burning house. The respiratory therapist
should recommend obtaining which of the following
measurements to best determine the sever- ity of the
patient's smoke inhalation?
A. SpO2
B. HbCO
C. PaO2
,3|Page
D. Hb - Answer-B, To best determine the severity of smoke
inhalation, an HbCO level should be determined with a co-
oximeter. The SpO2 value should never be evaluated on a
patient suspected of CO poisoning because a pulse
oximeter is not capable of determining what is bound to
hemoglobin.
Pulse oximeters work on the principle of
spectrophotometry where lightweight probes direct filtered
light of specific wavelengths through the skin or digit. The
light absorbed differs for saturated and desaturated blood,
whether it's saturated with oxygen or a combination of
oxygen and carbon monoxide. Therefore the reading will
be erroneously high when HbCO is present. (Analysis)
To best determine the severity of smoke inhalation, an
HbCO level should be determined with ? - Answer-co-
oximeter
The physician has ordered O2 to be administered to an
active 3-year-old with an SpO2 of 86%. Which of the
following delivery devices would you recommend for this
patient?
A. 1- to 2-L nasal cannula
B. Air-entrainment mask
, 4|Page
C. Simple O2 mask
D.O2 hood - Answer-A, An active 3-year-old generally
tolerates a cannula much better than any kind of mask and
is too large for an O2hood. (Application)
The ability of the patient to follow instructions would be
indicated by which of the following?
A. Orientation to person
B. Performance of tasks when asked
C. Ability to feed himself
D. Awareness of time - Answer-B, If the patient is able to
perform simple tasks when asked, this best determines his
or her ability to follow instructions. This is important before
administering an incentive spirometry or IPPB treatment,
which requires the patient to be able to follow instructions
well or the treatment will not be effective. (Recall)
