GUARANTEED PASS WITH 100+ QUESTIONS
A 10% pneumothorax is relatively small. A chest tube is not indicated; a needle
aspiration is indicated only when a tension pneumothorax is present, which is not
the case here on the basis of the patient's respiratory status. O2 therapy is
indicated because the patient is in mild respiratory distress, and O2 will help
absorb the air in the pleural space. Pulse oximetry should be employed to
continuously monitor the SpO2 level and help determine the patient's
oxygenation status.


After turning the O2 flowmeter completely off, you notice the water in the
humidifier is still slightly bubbling. What is the most likely reason for this?


a. The humidifier lid is not tight
b. There is a crack in the humidifier jar
c. The wall outlet is loose
d. There is a faulty valve seat in the flowmeter
- ANSWER d. There is a faulty valve seat in the flowmeter


The needle valve, when completely closed, fits into a valve seat. If the valve seat is
damaged and lets gas past it, the humidifier will bubble, but the flow is so low it
will not show a reading on the flowmeter. The flowmeter should be replaced.

,The following data are controlled from a patient receiving VC ventilation
AC Mode
Rate 122
Vt 750
FiO2 40%
pH: 7.29
CO2: 55
O2: 68
HCO3: 25


Based on this information, the most appropriate recommendation is which of the
following?
a. Increase the FiO2
b. Add PEEP
c. Increase the Vt
d. Decrease the Rate
- ANSWER c. Increase the Vt


The blood gas results reveal hypercapnia (high PCO2), which is corrected by
increasing the patient's minute ventilation. This is accomplished by increasing the
ventilator rate or VT. When the VT is increased, more volume is made available to
the alveoli for gas exchange to occur, thereby decreasing the PaCO2


a 26 year old pt has been experiencing a moderate asthmatic attack for 30
minutes. Which of the following ABG results would you expect to observe if the pt
was breathing RA?

,a. pH: 7.42 CO2: 44 O2: 81
b. pH: 7.08 CO2: 24 O2: 50
c. pH: 7.51 CO2: 27 O2: 60
d. pH: 7.27 CO2: 52 O2: 63
- ANSWER c. pH: 7.51 CO2: 27 O2: 60


Because the attack has been for only 30 min, the patient will most likely be
hyperventilating as a result of hypoxemia. If this condition is not reversed, the
patient will begin to tire, which will result in decreasing minute ventilation
accompanied by rising PaCO2 levels.


The RT is performing a leak test on a mechanical ventilator. Which adjustment
should the RT make to the ventilator?


a. Set the high pressure limit to its maximal level
b. set the rate control to its maximal level
c. set the flow control to its max level
d. Remove the test lung from the circuit
- ANSWER a. set the high pressure limit to its maximal level


To make sure there are no leaks in the ventilator circuit, the ventilator flow rate
should be set low with a moderate to high tidal volume. This results in a high peak
pressure, so the high-pressure limit must be increased.


If a patient's CO2 decreases to 27 all of the following could have increased except

, a. Vd
b. Va
c. RR
d. Vt –
ANSWER a. Vd


Be sure to read these questions carefully. This question is asking for "all of the
following EXCEPT." When physiologic dead space increases, it indicates less air is
getting to the normally functioning alveoli for gas exchange, while more is
occupying the anatomic dead space. This would result in increased, not
decreased, PaCO2 levels.


The RT is having difficulty calibrating a transcutaneous O2 monitor. This is most
likely because of which of the following?


a. The membrane is damaged
b. The sensor will not stick to the infant's skin properly
c. There is poor perfusion to the sensor site
d. The infant is hemodynamically unstable
- ANSWER a. The membrane is damaged


The transcutaneous O2 monitor is calibrated to room air while off the infant.
Therefore, the cause could not be related to the infant's hemodynamic status. The
problem must be with the monitor itself.
