UPDATE GRADED A+ WITH RATIONALES
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
Page 1 of 73
,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
Page 2 of 73
,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 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
Page 3 of 73
, 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
