An alert, spontaneously breathing pt has a PaCO2 of 33torr, and a PaO2 of
55torr while receiving an FiO2 of 70%. Which of the folllowing is the most
appropriate way to increase the pt's PaO2?
a. Increase the FiO2 only.
b. Intubate and increase the FiO2
c. Apply CPAP @ 60%
d. Apply CPAP @ 100%
- ANSWER c. Apply CPAP @ 60%
The blood gas data provided indicates the patient is hyperventilating with
hypoxemia while receiving 70% oxygen. This indicates an intrapulmonary shunt
and refractory hypoxemia with a dangerously high oxygen level. On the exams,
try to maintain adequate oxygen without exceeding 60% oxygen. If CPAP is
applied, FRC will increase and oxygenation should improve. This will allow the
oxygen level to be reduced to a safer level (60%).
The RT is assessing the pt's spontaneously ventilatory variables. The PaCO2 is
50torr and the PeTCO2 is 30torr, and the Vt is 600mL. What is the pt's dead
space volume?
a. 150
,b. 240
c. 360
d. 480
- ANSWER b. 240
((PaCO2 - PeTCO2) / PaCO2) x Vt = Vd/Vt Volume
The high pressure alarm on VC ventilation should be set approximately
10cmH2O pressure above which of the following?
a. PEEP level
b. Pplat
c. Mean Airway Pressure
d. Peak Airway Pressure
- ANSWER d. Peak Airway Pressure
To prevent excessive pressure in the lungs, set the high pressure limit around 5
to 10 cm H2O above the average peak airway pressure because peak airway
pressure is the highest pressure of the other choices.
While assessing a patient's chest radiograph, you observe an area of
hyperlucency. This may be the result of which of the following?
1. Hyperinflation
2. Atelectasis
3. Emphysema
4. Pneumothorax
, a. 1 and 3
b. 2 and 3
c. 1, 3 and 4
d. 2, 3 and 4
- ANSWER c. 1, 3 and 4
Lucency is defined as black areas on a chest film. Hyperlucency indicates
excessive black areas. Air is black on chest x-rays; therefore, more air is present
than normal. This is caused by hyperinflation, emphysema (due to air-trapping),
and a pneumothorax. When a pneumothorax is present, the lung collapses and
air enters into the pleural space. The excessive air in the pleural space results in
hyperlucency.
The RT is called to a patient's room to check the O2 setup. The flow to the pt's
non-rebreathing mask is supplied by an air flowmeter running @ 10L/min and
an O2 flowmeter running @ 10L/min. The delivered O2 percentage from this
device is
a. 24%
b. 35%
c. 40%
d. 60%
- ANSWER d. 60%
, Go back and review the air/O2 entrainment ratios in Chapter 1. Although we
do not use them clinically, the NBRC does have test questions on them. In this
