RPSGT Practice Test #1 Questions with Correct Answers (Grade
A+)
Question 1: while reviewing the scoring report, the tech noticed that the lowest SpO2 is listed as 0%
what should the tech do next? a. review the study, and lable bad data where the pluse oximeter falied.
b. do nothing as the report is accurate. c. reschedule the pt for a repeat study becasue of corrupted
data. d. check the pulse ox before attempting to generate the report again.
Answer: A. Review the Study and appropiately lable any bad data where the pulse oximeter failed. when
generating a report the data acquired will be plugged directly into the formula used to create the report
summary. all data that are a result of faulty equipment or patients removing items should be appropriately
labeled so taht the data do not throw off the accuracy of the scoring report.
Question 2: During a multiple sleep latency test (mslt) how is sleep onset defined? a. three or more
epochs of stage N1 or a single epoch of the othere sleep stages b. when spindles are seen c. the first 30
second epoch in which alpha begins to supside. d. the first 30 second epoch in which there is more
than 15 sec. of cumulative sleep.
Answer: D. in a MSLT, sleep onset is the first 30 second epoch in which there is more than 15 sec. of
cumulative sleep. for the purposes of determining how long the MSLt nap will last and sleep latency, sleep
onset is defined as the first spoch that has more than 50% of any stage of sleep in in. Arousals and
interruptions do on negate the possiblitity of sleep onset as long as the 15 sec. of total sleep is reached
within taht 30 second epoch.
Question 3: where are the reference electrodes M1 and M2 placed on the head? a. on the earlobes b.
on either side of the Cz elecrodes placement c. in the preauricular area behind the ear d. both A and
C
Answer: D. both A and C. The most common placement is the preauricular location behind the ears. for
patients with and abundance of fat tissue or and exceptional EEG arifact, M1 and M2 can be attached to the
earlobes instead. The itegrity of the entire EEG for the study relies on the proper placement of these
reference electrodes.
Question 4: True statements about the process of biocalibrations include of the the flollowing
EXCEPT a. the pt should be supine and still throughtout biocalibrations b. the tech's notes should
reflect the movements, made by the pt. c. biocalibrations are done at the begining of the study only.
d. nasal and oreal breathing are done on the NPSGs only,
Answer: C. biocalibrations are done at the begining and the end of every study. pts should be asked to lie
supine and still during the process. Each moements sohould e labeled xoeewxely in rhw study to reflect the
movement the pt was asked to perform. Nasal and oral breathing are only done on the NPSG as a means to
confermthat the thermistor and pressure transducer airflow cannula are functioning correctly.

, Question 5: Pts whol suffer form frequent sinus infections should be advied NOT to wear which of
the following masks? a. Nasal masks b. nasal-pillows c. full face d. all of the above.
Answer: B. nasal-pillow masks deliver the whole of PAP pressure into the nasal passages and directly into
the sinuses at the back ot the nose. For pts who have sasily irritated sinuses and nasal passages, the
nasal-pillow design causes them alot of discomfort. Pts should be screened for sinus issues before
determining the appropriate mask selection.
Question 6: what is the recommended minimum/maximum differential for IPAP and EPAP settings
during a BiPAP titration? a. 4-6 cm apart b. 6-10 cm apart c. 4-10 cm apart d. 2-8 cm apart
Answer: C. Dustin a BiPAP titration, the AASM recommends that the IPAP and EPAP remain at least 4 cm
apart; this is an industry standard. For special circumstances and complicated Pts, the AASM recommends
the spread between the IPAP and EPAP to go no higher than 10 cm apart. It is important to understand that
any differential above 6 cm apart will more closely resemble a manual centilation of the pts breathing as
opposed to 4-6 cm apart, which is standard BiPAP. Greater taht 6 cm apart is a less common differential
typically used to assist pts in breathing excess carbon dioxide or special treatment of complex sleep apnea.
These complex titrations should not be done without guidance and proper training.
Question 7: the physician's orgers indicate taht the pt is in the lab for a CPAP titration study; all of
the following solutions woud be acceptable to resolve this situation EXCEPT a. call a member of the
lab management team. b. run the study according to the physicians orders without verification. c.
attempt to contact the ordering phusician, and verify the medical intent. d. look through the pts
chart for evidence of a previous study.
Answer: B. a study should never begin without order verifacation when the discrepancies are suspected. It is
important to avoid telling pts that they are confused or mistaken about their own medical history, even if it
is true. The corect course of action is to call management about the discrepancy, and follow up with the
phusician in case of verbal alterations to the orders are required.
Question 8: while in the sleep lab, a pt has to do all the following EXCEPT a. sign a consent form b.
have PSG equiptment attached to the body. c. remain connected to equipment for at least 6 hrs. d.
remain supine for the entire study.
Answer: D. a medical consent for is always required for any procedure, and a sleep study is a medical
procedure. A pt may not give verbal permission as consent. for a PSG study to begin, the equipment must be
attached, and for the study to be calid for diagnosis, the pt must remain connected for no less than 6 hrs. a pt
is not required to lay down for the study. in some cases, pt sleep sitting upright; pt should not be forced to lie
down during times of stress or anxiety.
