Lindsey Jones Practice Exam Qs w/Explanations UPDATED 2024/25 RATED
A+
1. A patient has undergone overnight oximetry. Data shows several episodes of O2
desaturation throughout the night. The RTT would expect orders for which of the
following kinds of testing:
a. V/Q scan
b. pulmonary function testing
c. polysomnography
d. 24-hour Holter monitoring - Your answer: C
Correct answer: C
The use of overnight oximetery is often used to detect O2 desaturation during the night
that may be associated with central or obstructive sleep apnea. Because data indicates
some periodic desaturation, the practitioner should suspect possible sleep apnea and
should order diagnostic testing that will confirm or rule out the suspicion.
A routine screening blood gas performed on an asymptomatic patient prior to surgery
shows the following:
pH: 7.38
PaCO2: 42
PaO2: 80
HCO3: 26
SaO2: 96%
COHb: 24%
What should the RRT do?
a. place the patient on a NRB mask
b. report the findings and emphasize that the patient is likely a smoker
c. evaluate saturation using a single wave-length spectrophotometer
d. run quality control material and evaluate the accuracy of the co-oximeter - your
answer: D
correct answer: D
In this case the patient is presented as asyptomatic. A patient with a COHb level of 24%
would feel dyspnea and present with tachypnea. Therefore, the RRT should evaluate
the accuracy of the lab results, specifically the COHb. When checking accuracy of lab
results, one would use quality control measures.
, The infection control department of a small hospital informs the RRT supervisor that the
biological control accompanying some durable autoclaved equipment shows viable
spores. The supervisor should do which of the following with the equipment:
a. incinerate
b. record date and place into service
c. wipe with isopropyl alcohol before use
d. resterilize - your answer: D
correct answer: D
The presence of viable spores indicates the possibility of living organisms developing in
the sterilized package or on the sterilized equipment. Sterilization suggest the absence
of living organisms, therefore the presence of viable spores indicates the need to
resterilize.
A post-op patient is not progressing with sustained maximal inspiratory therapy and
refuses to cough because of pain along the incision site. The RRT should instruct the
patient to:
a. pause at the top of each inspiration
b. press a pillow against the incision site when coughing
c. attempt coughing 1 hour after pain medication has been administered
d. avoid coughing until the pain subsides - your answer: B
correct answer: B
Explosive coughing by a post-op patient can inadvertently open incision sites. To
prevent this, splinting the site with a pillow is an appropriate option.
Several hours after oral endotracheal extubation of an 8.0-mm tube, and adult patient
begins to demonstrate inspiratory stridor. Which of the following would be most helpful
to the patient:
a. racemic epinephrine
b. albuterol
c. atropine sulfate
d. heated aerosol by mask - your answer: A
correct answer: A
When a patient is extubated and has swelling of the upper airway tissues as
demonstrated by stridor, racemic epinephrine is an appropriate medication to reduce
swelling quickly. Another, less effective option, is to provide a cool mist. In extreme
cases, such as marked stridor, reintubation, or an emergency tracheotomy may be
indicated.
, An adult patient is receiving mechanical ventilatory support and is being suctioned
through the endotracheal tube at a pressure of -90 mmHg. Secretions have been
difficult to remove. What can be done FIRST to increase suctioning efficiency:
a. increase suction time
b. decrease suction to 80 mmHg
c. increase suction pressure to 100 mmHg
d. increase suction catheter size - your answer: C
Correct answer: C
An increase in suctioning effectiveness is done through three different ways - increasing
suction catheter diameter, increasing suction pressure, and increasing suction time.
Before increasing catheter size, the first thing that should be done is to ensure the
appropriate range of suction pressure is being used. In this case, the appropriate
suction pressure for an adult is 100-120 mmHg. A pressure of 90 mmHg is being used,
which is insufficient suction pressure. This should be corrected before doing anything
else to increase suction effectiveness.
A chemical indicator tape found inside the sealed, packeaged disposable mask helps
determine which of the following:
a. if the equipment is sterile
b. if the equipment has been properly sterilized
c. if microorganisms remain viable on the equipment
d. if the package has remained closed - your answer: A
correct answer: B
A chemical indicator tape inside a sterilized package does not actually indicated the
presence or absence of viable spores. It does, however, indicate if the equipment has
been through the sterilization process.
A 23-year old female patient in active child labor is receiving O2 by partial-rebreathing
mask at 9/L/min. The reservoir bag collapses completely during contractions due to the
patient's deep rapid breaths. The RRT should recommend:
a. increasing the flow to the mask
b. changing to a nasal cannula
c. changing to 100% NRB
d. coaching the patient to take smaller breaths - your answer: C
correct answer: A
When the reservoir bag on a non-rebreather mask collapses completely with each
breath, the problem is most likely due to insufficient flow to the mask.
A radiology report of a chest x-ray indicates the end of the radio-opaque line on an oral
endotracheal tube is resting 1 cm above the carina. The RRT should suggest:
, a. advance the ET tube 1 cm
b. withdraw the ET tube 2 cm
c. withdraw the ET tube 5 cm
d. advance the ET tube 2 cm - your answer: B
correct answer: B
The ET tube is properly positioned when the end is 2-5 cm above the carina. In this
case, the tube is only 1 cm above the carina. Withdrawing the ET tube by 2-4 cm is
appropriate.
Peak flow measurements are indicated in which of the following conditions, if present?
a. ARDS
b. airway obstruction
c. myasthenia gravis
d. Guillain-Barre - your answer: A
correct answer: B
Peak flow measurements are especially helpful in patients with asthma or patients who
are suspected to have airway obstruction, mostly due to bronchoconstriction.
A female patient is intubated with a 7.0 mm ET tube. The tube is noted to be positioned
at 26 cm at the teeth. Breath sounds are not bilateral. Which of the following will best
confirm placement of the artificial airway:
a. capnography
b. chest radiograph
c. chest rise
d. breath sounds - your answer: B
correct answer: B
There are several ways to assess proper ET tube placement, such as auscultation of
breathsounds, observance of symmetric chest rise, or end-tidal CO2 evaluation.
However, this scenario asks for confirmation of proper placement, which is
accomplished with a chest x-ray.
A blood gas analyzer fails again to produce acceptable results on the pH value when
running quality control material for the second time. The RRT should:
a. remove the machine from service
b. perform a one-point calibration
c. perform proficiency testing
d. monitor future results - your answer: A
correct answer: A
