PSG TESTING 2 MIDTERM - QUESTIONS AND ANSWERS WITH COMPLETE SOLUTION.
40 minutes - (ANSWER)What would the sleep latency for trial #1 be calculated at if the patient stayed
awake the whole time during the first MWT trial?
15 - (ANSWER)After the first epoch of sleep occurs, how any minutes are recorded before the MSLT is
terminated (beginning with the start of the epoch of sleep)?
20 - (ANSWER)After the lights out, how many minutes of continuous wake are allowed before an MSLT
nap is terminated (maximum sleep latency)?
40 min test is recommended - (ANSWER)Which of the following is true concerning the MWT?
Psg required; pt. out of bed between naps - (ANSWER)Which of the following are true about the
recommended MSLT protocol?
5 percent - (ANSWER)Excessive sleepiness affects about what percentage of the population?
- (ANSWER)A 40-year-old policeman is evaluated for falling asleep on the job. He denies cataplexy
(emotionally induced weakness). A PSG finds an AHI of 25/hr. with many obstructive apneas. An MSLT is
preformed and shows an MSL of 4 minutes and 2 SOREMPs. What is the most likely diagnosis?
- (ANSWER)A lawyer regularly flies an airplane for recreation on the weekends. During an FAA medical
evaluation, a history of snoring was noted. Subsequently, a PSG showed moderate to severe OSA. After
treatment with CPAP, the patient somewhat sleepy and began taking modafinil (alerting agent). To
receive medical clearance for pilot s license, a PSG (to document adequate CPAP) with a subsequent
MWT was ordered. The PSG found an AHI of 3/hr. on CPAP treatment patient took his usual modafinil
before the MWT and the MSL on four naps was 40 minutes. What do recommend? Choose all that
apply.
- (ANSWER)All of the following concerning the MWT protocol are true EXCEPT:
3 consecutive epochs of N1 sleep, any -N1 stage of sleep - (ANSWER)Unequivocal sleep is defined by:

False - (ANSWER)Patients are not allowed to eat after MSLT of MWT are concluded.
30 - (ANSWER)Smoking should be stopped _____ before each nap begins.
2 - (ANSWER)Stimulants should be discontinued ideally about _______ week before an MSLT.
