RPSGT Practice Test #1 Correct 100%(RATED A+)

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. 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. 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. 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. 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. 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
