Your Secret Weapon for Acing The Exam. https://www.certswarrior.com/exam/rst/ Question: 1 What is the highest grade level at which patient education materials and consent forms for polysomnography should be written? A. 2nd to 4th grade B. 3rd to 4th grade C. 4th to 6th grade D. 6th to 8th grade Answer: D Explanation: The materials should be written at a level that is not higher than a 6th to 8th grade level. Regardless of educational level achieved, the average American reads effectively at the 6th to 8th grade level. Readability index calculators, which provide an approximation of grade level and difficulty for reading materials, are available online. Question: 2 In a patient with pseudohypertrophic Duchenne muscular dystrophy, which of the following is NOT a typical sleep-related problem? A. Hypercapnia and oxygen desaturation during sleep B. Decrease in vital capacity to less than 2 L C. Central sleep apnea D. Increasing sleep disruption Answer: C Explanation: The correct answer is central sleep apnea. Patients with pseudohypertrophic Duchenne muscular dystrophy typically have obstructive sleep apnea, not central sleep apnea. Typical problems include hypercapnia and oxygen desaturation during REM sleep, progressing to non-REM sleep as the condition worsens. More typical problems include a decrease in vital capacity to less than 2 L and increasing sleep disruption. Question: 3 Which type of waves have a frequency of 13-35 Hz, an amplitude of less than 30 gV, and are present during normal wakefulness when the patient is alert? A. Delta waves B. Beta waves C. Vertex waves D. Theta waves Answer: B Explanation: The correct answer is beta waves. Delta waves are slow waves (1-4 Hz), with an amplitude of more than 75 gV, and are present in stage 3 non-REM (slow-wave) sleep in adults. Delta waves occur in the waking state of newborns and young children and may occur in adults who are intoxicated or have schizophrenia or dementia. Vertex waves are commonly found negative deflections, with amplitude typically ranging from 50-150 μ V. Vertex waves are most noticeable from the vertex and frontal leads. They may have sharp contours and occur in repetitive episodes (particularly in children). By contrast, theta waves have a frequency of 4—6 Hz and oscillations of varying amplitude, and are most easily seen with central and temporal leads. Theta waves frequently occur during daydreaming and self-hypnotic states, occur in stage I non-REM sleep, and may occur during arousals. Question: 4 During polysomnography, which of the following can be created by skin irritation, such as a rash? A. High-frequency artifacts B. Spike in EEG C. High impedance D. Slow waves Answer: C Explanation: The correct answer is high impedance. A skin rash can change the skin's electrical signal. When this occurs, the technician should reposition the electrode, avoiding the irritated skin. By contrast, vibration may cause high-frequency artifacts. Swallowing can result in slow waves on EEG, and the blink produces slow waves on EOG. Eye muscle abnormality can cause a spike on EEG. Question: 5 Pulse oximetry measures A. arterial oxygen saturation (Sp02) B. electrical activity in the leg muscles C. vertical and horizontal eye movements D. the degree and duration of snoring Answer: A Explanation: Pulse oximetry measures arterial oxygen saturation (Sp02). By contrast, anterior tibialis electromyograms (atEMGs) monitor electrical activity in the leg muscles. When the leg muscles are relaxed, electrical activity is not present. With movement. electrical activity increases. The EOG records both vertical and horizontal eye movements and helps the observer to identify periods of REM sleep. Microphones or piezo sensors are used to indicate the degree and duration of snoring. Question: 6 When periodic limb movements of sleep are scored as events, which of the following is FALSE? A. An event ranges in duration from 0.5-10 seconds, with an EMG amplitude of 8 LV or more B. Timing of the event begins at the point of an 8-uV increase on EMG C. Timing of the event ends with a period, lasting 0.5 seconds or longer, during which EMG does not rise more than 2 LIV D. An event requires four or more consecutive leg movements, with the interval between movements ranging from 5-90 seconds Answer: D Explanation: Statements A-C are all true. Periodic limb movements of sleep are scored as either events or series. It is a series (not an event) that requires four or more consecutive leg movements with the interval between movements ranging from 5-90 seconds. Leg movements that involve both legs are counted as one movement if they occur within 5 seconds of one another. Question: 7 Which of the following is NOT a way to decrease the amount of condensation in humidifier tubing? A. Using heated tubing B. Reducing the level of humidification C. Insulating the tubing D. Decreasing room temperature at night Answer: D Explanation: As air becomes cooler, its ability to hold water decreases. As a result, condensation begins to form in the tubing. This causes audible gurgling and decreased pressure, which are important to avoid in order for effective therapy to occur. One solution is to increase (not decrease) the room temperature by 5 to 6 degrees at night. Other potential solutions include using heated tubing and reducing the level of humidification. Another potential solution is to insulate the tubing to reduce the effects of ambient temperature. Question: 8 Which of the following is true with regard to electrode impedances? A. Electrodes should be tested together in groups of three B. When there is a difference in impedance between electrodes, the number of artifacts is reduced C. Impedance levels for each individual electrode should be less than or equal to 5 kΩ D. The technologist should verify the electrode impedances before calibrating the machine Answer: C Explanation: The impedance levels for each individual electrode should be less than or equal to 5 kn. Electrodes should be tested individually (not in groups of three) with an internal impedance meter or an external handheld meter. When there is a difference in impedance between electrodes, it increases artifacts. The sleep technologist should verify the electrode impedances after calibrating the machine. Question: 9 Which of the following is FALSE with regard to liquid oxygen? A. It is stored at -183'C in special cryogenic containers B. It is maintained at 18 psi C. As the tanks slowly warm, the oxygen evaporates D. Touching the fill valve can result in burns Answer: B Explanation: Liquid oxygen is maintained at 21 psi, not 18 psi. It is true that it is stored at temperatures of -183zc in special cryogenic containers that oxygen evaporates as the tanks slowly warm, and that touching the fill valve can result in burns. Question: 10 Which of the following disorders involves sudden or gradual onset of loss of language skills and is characterized by nocturnal multifocal spikes and spike-wave discharges? A. Temporal lobe epilepsy B. Lennox-Gastaut syndrome C. Landau-Kleffner syndrome D. Dementia with Lewy bodies Answer: C Explanation: Landau-Kleffner syndrome involves sudden or gradual onset of loss of language skills and is characterized by nocturnal multifocal spikes and spike-wave discharges. Temporal lobe epilepsy is characterized by an increase in interictal epileptiform activity (IEA) in non-REM sleep with high- frequency spikes and contralateral focal discharges. It is also characterized by a reduction in REM sleep. Lennox-Gastaut syndrome is an intractable seizure disorder characterized by many kinds of seizures, which occur throughout waking and sleeping, and by intellectual disability. Dementia with Lewy bodies is characterized by cognitive and physical decline, with symptoms that fluctuate often. A primary feature on polysomnography is REM behavior disorder.
