b. Too much water in the circuit Correct Answer A patient with a
tracheostomy is receiving supplemental oxygen via tracheostomy
collar connected to a large volume nebulizer set at 40%. The
respiratory therapist analyzes the FIO2 at the tracheostomy collar
with a galvanic fuel cell analyzer. The analysis shows the FIO2 to
be 55%. Which of the following could be the cause of the increase
in FIO2?
a. The aerosol tubing is too short
b. Too much water in the circuit
c. Calibration error in the galvanic fuel cell
d. Clogged jet orifice in the nebulizer
a. Use of pressure support Correct Answer A patient receiving
volume-controlled ventilation in SIMV mode has a total respiratory
rate of 26/min and is showing signs of increased labor of
breathing. The mandatory rate is 14/min. Which of the following
would most likely help the patient?
a. Use of pressure support
b. Switch to pressure control ventilation
c. Increase the machine flow rate
d. Increase PEEP
d. Cardioversion Correct Answer A patient is experiencing atrial
arrhythmias and is complaining of light-headedness and nausea.
Which of the following should the respiratory therapist
recommend to help remedy the problem?
a. Administration of Lidocaine
,b. Atropine sulfate
c. Unsynchronized defibrillation
d. Cardioversion
a. 1/2 Correct Answer When selecting a suction catheter to be
used in an oral endotracheal tube, the respiratory therapist should
select a catheter whose diameter should not exceed what fraction
of the internal diameter of the endotracheal tube?
a. 1/2
b. 2/3
c. 3/4
d. 1/4
d. Flow volume loop Correct Answer Which of the following would
be most helpful in diagnosing vocal cord paralysis in an adult?
a. FVC maneuver
b. Thoracic gas volume measurement
c. Neck radiograph
d. Flow volume loop
d. Change the nebulizer entrainment port to 100% Correct
Answer When analyzing the FIO2 for an infant in an oxygen hood
receiving oxygen therapy with a blender set at 50%, the
respiratory therapist notes an oxygen concentration of 35% near
the patient's mouth. The jet nebulizer entrainment setting is set to
50%. To correct the problem, the therapist should
a. Obtain a smaller oxyhood
b. Increase total flow to the oxyhood
c. Adjust blender setting to 60%
d. Change the nebulizer entrainment port to 100%
a. Hyperlucency in the soft tissues Correct Answer Following the
insertion of a tracheostomy tube, the patient is found to have
diffuse crackles upon auscultation secondary to subcutaneous
,emphysema. Which of the following radiographic findings would
be expected with this condition?
a. Hyperlucency in the soft tissues
b. Scattered patchy infiltrates
c. Diffuse pulmonary hyperlucency
d. Tracheal shift from midline
d. Cardiac arrhythmias Correct Answer Placement of a
pulmonary artery catheter is associated with which of the
following most common complications?
a. Internal bleeding
b. Pulmonary valve damage
c. Hypotension
d. Cardiac arrhythmias
d. Inflate the catheter balloon to sail the tip to the proper location
Correct Answer During the placement of a pulmonary artery
catheter, the respiratory therapist observes the waveform on the
monitor and notices it is repeatedly rising and falling from 0
mmHg to 25 mmHg, which is an indication that the tip of the
catheter is in the right ventricle of the heart. Based on this
information, the respiratory therapist will recommend
a. Rotate the catheter to achieve a dicrotic notch in the waveform
b. Suture the catheter in place
c. Withdraw the catheter back to the upper vena cava
d. Inflate the catheter balloon to sail the tip to the proper location
a. MVV Correct Answer A patient has been gradually weaning
from mechanical ventilation for the past two weeks. The physician
requests data to determine the patient's current ability to breathe
on his own. Which of the following tests would not be indicated?
a. MVV
b. MIP
c. VC
d. VT
, b. Carboxyhemoglobin level Correct Answer The most reliable
test to determine if a pulmonary rehab patient has stopped
smoking is a
a. Methemoglobin level
b. Carboxyhemoglobin level
c. Complete PFT
d. Treadmill trial
c. Discontinue suctioning Correct Answer While performing nasal
tracheal suctioning on a patient with mycoplasma pneumonia, the
respiratory therapist notices PVCs on the monitor. The first action
of the therapist should be to
a. Decrease the suction pressure
b. Recommend administration of Lidocaine for future suctioning of
the patient
c. Discontinue suctioning
d. Monitor the patient carefully
a. When a volume-controlled ventilator at high inspiratory
pressures Correct Answer A galvanic fuel cell oxygen analyzer
may read erroneously high under which of the following
conditions?
a. When a volume-controlled ventilator at high inspiratory
pressures
b. During a sudden increase in the partial pressure of oxygen
c. When liquid gets on the membrane
d. When the analyzer batteries are depleted
c. Inaccurate Correct Answer Results of a quality control
maneuver for a spirometer using a 3.0 L calibration syringe as
follows:
Volume 1 2.65 L
Volume 2 2.68 L
Volume 3 2.66 L
