QUESTIONS WITH REVISED AND
UPDATED ANSWERS GRADED A+
- An orally intubated comatose patient who is being mechanically ventilated with a
volume ventilator frequently bites the endotracheal tube. During these times, the high
pressure and low exhaled tidal volumes activate. Which of the following actions would
correct the problem? - Answer-Reintubate the patient with a nasotracheal tube
- A patient exhibits extreme respiratory distress after the respiratory therapist plugs the
outer cannula of the patient's fenestrated tracheostomy tube. The respiratory therapist's
first action is to immediately unplug the outer cannula. The next action is to: - Answer-
Ensure that the cuff of the fenestrated tracheostomy tube is deflated
- While assessing a patient who is receiving supplemental oxygen at 28% via
tracheostomy tube, the respiratory therapist notes pulsatile movement of the tube.
Which of the following should the therapist do next? - Answer-Reposition the
tracheostomy tube
- Physical and diagnostic findings of a trauma patient involved in a motor vehicle
accident include multiple facial and scalp lacerations with possible head injury. The
most recent chest x-ray reveals a massive hemopneumothorax of the left lung but with
no trauma to the right lung. The patient requires airway protection and mechanical
ventilation. Which of the following would be most appropriate for this patient? - Answer-
Double-lumen endotracheal tube
- Several interventions have been shown to be effective in reducing the incidence of
ventilator-associated pneumonia (VAP). Which of the following would not be an
appropriate intervention? - Answer-Routine saline lavage through the endotracheal tube
during suctioning
- The standard objective behind quality control procedures for respiratory equipment is
that: - Answer-All equipment should perform within stated accuracies
- The quality control procedure useful for detecting and/or preventing malfunctions
which could improve compliance and outcome of home mechanical ventilation is which
of the following? - Answer-Regularly assessing the actual performance of the ventilator
at the patient's home.
- A respiratory therapist is reviewing the Levey Jennings control chart shown above for
a blood gas analyzer. Which of the following best explains Sample Number 8?
,(Number 8 is the only deviation out of standard deviation testing) - Answer-Random
Error
- A vane-type respirometer is used to monitor several patients in the intensive care unit.
The most practical method to prevent cross contamination would be to: - Answer-Use
an extension piece with a one-way valve for each patient
- While caring for a patient with severe acute respiratory syndrome (SARS), the
respiratory therapists face shield becomes contaminated. When ready to leave the
patient area, the respiratory therapist should do which of the following? - Answer-
Remove the face shield by handling only the portion that secures it to the head and then
dispose of it properly
- When initiating mask CPAP for an adult patient, the flow rate should be set at which of
the following? - Answer-Set to achieve minimal fluctuation in the CPAP pressure
- Which of the following statements is NOT true regarding a fenestrated tracheostomy
tube? - Answer-Insertion of the inner cannula opens the fenestration
- A patient with an unstable ventilatory pattern who needs a low concentration of oxygen
would best benefit which of the following devices? - Answer-Air-entrainment mask
Magill forceps are generally used during which of the following procedures? - Answer-
Nasotracheal intubation
Which of the following humidifying devices is the most economical choice for use in an
intubated, mechanically ventilated patient who only needs short-term intubation? -
Answer-Heat moisture exchanger
- The respiratory therapist notices that the CPAP pressures indicated on the low
pressure monitor is consistently less than the preset CPAP on an infant's nasal CPAP
system. Which of the following should the therapist do FIRST to correct this problem? -
Answer-Tighten all connections
- Upon entering a patient's room, the respiratory therapist notes that the patient is on a
simple oxygen mask with a flowmeter setting of 2 L/min. The therapist could conclude
that: - Answer-The patient is rebreathing carbon dioxide
- While observing a patient using her metered dose inhaler (MDI), the respiratory
therapist notes that the patient has difficulty in coordinating her inspiratory effort with
actuation of the MDI. Which of the following would be beneficial for this patient? -
Answer-Addition of a holding chamber to the MDI
Prior to taking a pulmonary artery wedge pressure (PAWP) reading, the practitioner
should ensure that: - Answer-The transducer is properly leveled and zeroed.
, The fiberoptic bronchoscope is usually the preferred device during a bronchoscopy
because of its: - Answer-Flexibility
- While checking the volume ventilator that is to be used for a coronary care patient, the
respiratory therapist observes that the displayed exhaled tidal volume is 250 mL less
than the preset tidal volume setting. Appropriate actions to correct this problem include
all of the following EXCEPT: - Answer-Increase the preset tidal volume setting by 250
mL
- A patient is receiving continuous ventilatory support with the following settings:
Upon entering the patient's room, the respiratory therapist hears the low pressure alarm
sounding and observes that the system pressure manometer rises 3 to 5 cmH2O during
the inspiratory phase. Which of the following would be the most appropriate action? -
Answer-Reconnect the exhalation line.
- The capnogram tracing above was obtained from a mechanically ventilated patient. On
the basis of this tracing, the respiratory therapist should: - Answer-Check the exhalation
valve
- An adult male patient is receiving mechanical ventilation in the SIMV mode with the
following settings:
The ventilator continuously reverts to back-up apnea ventilation. Which of the following
would correct this problem? - Answer-Increase the apnea interval
- A neonatal patient is being monitored via transcutaneous oxygen monitor with the
electrode placed on the patient's chest. The electrode temperature is set at 44 C. The
TcPO2 reading is 159 mmHg, but an arterial blood gas sample obtained concurrently
