Lindsey Jones final TMCCondensation has developed on the fuel cell of a galvanic oxygenation analyzer. Which of the
following is true?
A. The fuel cell should be replaced
B. The analyzer will still function properly
C. The gold grid in the analyzer should be replaced
D. The reading will be erroneous
D. The reading will be erroneous
Condensation on the fuel cell of a galvanic-type oxygen analyzer may result in an erroneous
reading of oxygen percentage.
A sputum gram stain report indicates the presence of a gram-positive organism (diplococcus) in
the sputum. The following data is available:
WBC 28,000 cu mm
Hb 14.5 g/dL
RBC 4.6 g/dL
HCT 42%
Which of the following medication would be most appropriate?
A. vancomycin
B. gentamycin
C. budesonide
D. amoxicillin
D. amoxicillin
Gram positive organisms, such as diplococcus, staphylococcus, etc) are treated using penicillin
class antimicrobials. These include penicillin, amoxicillin, carbenicillin, and others.
Which of the following data should be recorded in the patient's medical record after the therapist
coaches a post-op patient through sustained maximal inhalation therapy with a volume-oriented
incentive spirometer?
A. expiratory reserve volume
B. inspiratory reserve volume
C. inspiratory capacity
D. vital capacity
,C. inspiratory capacity
If the patient is using a volume oriented incentive spirometer, inspiratory capacity must be
included in the documentation in the medical record.
A 39-week gestational age neonate delivered 1 hour prior requires oxygen by hood. Which of
the following devices should be assembled?
1. aerosol heater
2. O2/air blender
3. large-bore tubing
4. oxygen analyzer
A. 2, 3, and 4
B. 1, 2, 3, and 4
C. 1, 3, and 4
D. 1, 2, and 3
B. 1, 2, 3, and 4
Because maintaining constant body temperature is paramount for an infant, use of an aerosol
heater is important. An oxygen-air blender, along with large-bore corrugated tubing will also be
needed to deliver supplemental oxygen. Additionally, an oxygen analyzer will be needed to
determine, maintain, and adjust FIO2 as needed.
The respiratory therapist notices a disparity in the heart rate as reported by an SpO2 monitor
and a finger probe compared to a palpated heart rate. Which can best explain this?
1. poor peripheral perfusion
2. excessive ambient light
3. presence of finger-nail polish
4. low hemoglobin
A. 1, 2, and 3 only
B. 1 and 4 only
C. 2 and 3 only
D. 2, 3, and 4 only
A. 1, 2, and 3 only
A 150-lb (68-kg) male is receiving volume-cycled mechanical ventilation on the following
settings:
,Mode SIMV
Rate 16
VT 450 mL
FIO2 0.45
PEEP 12 cm H2O
Peak Pressure 32 cm H2O
Which of the following alarm settings is most appropriate?
A. Low VT 350 mL, low pressure 22 cmH2O, high pressure 45 cmH2O
B. Low VT 350 mL, low pressure 30 cmH2O, high pressure 35 cmH2O
C. Low VT 400 mL, low pressure 20 cmH2O, high pressure 50 cmH2O
D. Low VT 300 mL, low pressure 30 cmH2O, high pressure 48 cmH2O
A. Low VT 350 mL, low pressure 22 cmH2O, high pressure 45 cmH2O
The low VT alarm should be set at 100 mL below VT, low-pressure should be set at 10 cm H2O
below baseline peak pressures, and the high-pressure limit alarms should be set 10-15 cm H2O
above the baseline peak pressure.
A patient is orally intubated and receiving mechanical ventilation. The respiratory therapist notes
the PetCO2 monitor is persistently reading 60 mmHg. Which of the following can the therapist
conclude?
A. the patient is being hyperventilated
B. the CO2 detector is covered with condensate
C. minute ventilation should be increased
D. the infrared device is not working properly
C. minute ventilation should be increased
End-tidal CO2 is correlated to arterial CO2. An end-tidal CO2 reading of 60 mmHg correlates
with an arterial CO2 of 70 mmHg. This is clearly hypoventilation and should be addressed by
increasing minute ventilation.
Local FEMA representatives have asked a hospital to prepare for intermittent, sweeping power
outages in the area due to a nearby passing F4 hurricane. Which of the following would be the
most important preparation that a respiratory care supervisor should consider?
A. Call for extra staff to report the hospital.
B. Instruct nurses on proper techniques for providing manual resuscitation.
C. Contract an equipment rental company for extra ventilators.
D. Check the function of back-up power outlets (red plugs) in critical areas.
D. Check the function of back-up power outlets (red plugs) in critical areas.
, Of the options listed, checking for the proper operation of red plugs during a power outage is
most helpful. It would also be appropriate to ensure vital equipment (life support machines) are
plugged into those red outlets.
Which is the preferred order to manipulate a mechanical ventilator in order to gradually increase
alveolar minute ventilation while limiting MAP?
A. increase VT, increase RR, decrease mechanical deadspace
B. increase RR, decrease mechanical deadspace, increase VT
C. increase VT, decrease mechanical deadspace, increase RR
D. decrease mechanical deadspace, increase VT, increase RR
D. decrease mechanical deadspace, increase VT, increase RR
MAP, or mean airway pressure, does not increase as mechanical deadspace is decreased.
Increasing the tidal volume will increase the mean airway pressure, but not as much as
increasing the respiratory rate will.
Which of the following cannot be measured or evaluated in a comatose patient?
A. tidal volume
B. pupillary response
C. objective information
D. symptoms
D. symptoms
If the patient is comatose, they cannot cooperate with procedures or follow commands. To
answer this question one must pick the option that does not require compliance with verbal
commands. Symptoms, coming from the root word sympathy, require the patient to tell you
something. From the list only a tidal volume can be measured without help from the patient. But,
the question is asking which of the following CANNOT be measured in a comatose patient.
Therefore symptoms, vital capacity, maximum inspiratory pressure are all appropriate answers.
Prior to intubation, a physician has ordered succinylcholine chloride (Anectine) for a male
patient to facilitate the procedure. Which of the following is true regarding this medication?
A. can be reversed with Atropine
B. also known as Pavulon
C. response time is 30 minutes
D. intubation should begin once muscle twitching is observed about the face and neck
D. intubation should begin once muscle twitching is observed about the face and neck
