2. Latest Version: 6.0 Question: 1 What is the time constant? A.The amount of time it takes for a signal to fall to 37% of the original calibration amplitude. B.The amount of time it takes for a signal to rise to 63% of its peak amplitude. C.The amount of time it takes for a signal to fall to 63% of the original calibration amplitude. D.The amount of time it takes for a signal to rise to 37% of its peak amplitude. Answer: A Explanation: The amount of time it takes for a signal to fall to 37% of the original calibration amplitude is called the time constant. It is also sometimes referred to as the fall time. The rise time is the time it takes a signal to rise to 63% of its peak amplitude. Question: 2 Which filter would be used to adjust the rise time of a signal? A.The LFF. B.The HFF. C.The gain. D.The sensitivity. Answer: B Explanation: The HFF, or high frequency filter, is used to adjust the rise time of a signal. The higher this filter is set the faster the signal wave will rise. The LFF is used to adjust the time constant, or fall time. Gain and sensitivity mean the same thing and will not affect the shape of the wave, only the size of the signal display. Question: 3 What is the difference between a thermocouple and a pressure transducer? A.The thermocouple measures the temperature of air going into and out of the nose and oral cavity whereas the pressure transducer measures changes in air pressure going into and out of the nose and oral cavity.

3. B.The thermocouple measures the changes in air pressure going into and out of the nose and oral cavity whereas the pressure transducer measures the temperature of air going into and out of the nose. C.The thermocouple measures the temperature of air going into and out of the nose and oral cavity while the pressure transducer measures the changes in air pressure going into and out of the nose only. D.The thermocouple can be used to measure both the airflow and the air volume. Answer: C Explanation: The thermocouple, also called a thermistor, measures the changes in temperature of air going into and out of the nose and mouth and thereby gives an airflow signal. The pressure transducer creates an airflow signal by measuring the change in air pressure going into and out of the nose only. Neither sensor can measure the air volume. Question: 4 What is the difference between SpO2 and SaO2? A.They both measure the amount of hemoglobin in the patient's blood that is saturated with oxygen, but SaO2 is the more accurate reading. B.SpO2 stands for oxygen saturation as measured by a pulse oximeter. SaO2 stands for oxygen saturation as measured by an arterial blood gas. C.There is no difference between them. D.Both A and B. Answer: D Explanation: Both A and B are correct. Both SpO2 and SaO2 are measures of the same thing, the amount of hemoglobin that is saturated with oxygen in a patient's blood, but SaO2 is the more accurate measurement because it is measured by an arterial blood gas. Question: 5 If the total circumference of a head is 58 cm, using the International 10-20 Electrode Placement System, what is the distance between M1 and 01? A.14.5 cm. B.29 cm. C.11.6 cm. D.2.9 cm. Answer: C Explanation: Visit us athttps://www.certsgrade.com/pdf/brpt-rpsgt/

4. M1 and 01 are 20% of the total circumference of the head away from each other, so if the total circumference of the head is 58 cm then. When dealing with percentages of the total head circumference in electrode placement, multiply the total circumference by the percentage that a lead should be placed in relation to your reference lead. In this case 58×20% (or 0.2) yields the correct answer of 11.6 cm. Question: 6 Using the International 10-20 Electrode Placement System, the C4 lead is located at what percentage of the total distance between the preauricular points away from the C3 lead? A.20%. B.30%. C.40%. D.50%. Answer: C Explanation: The C4 lead is located on the right side of the head 40% of the total distance between the preauricular points away from the C3 lead that is on the left side of the head. Directly in between the two (20% of the total distance between the preauricular points) is the Cz ground lead. An example of this would be if a head had a total distance of 52 cm from the left preauricular point to the right, then the C3 would be 20.8 cm away from the C4 lead. Question: 7 Where is the 01 lead located in relation to the T3 lead? A.Left and behind, 25% of the total circumference of the head. B.Right and behind, 25% of the total circumference of the head. C.Left and behind, 20% of the total circumference of the head. D.Right and behind, 20% of the total circumference of the head. Answer: C Explanation: The 01 lead is on the left side of the head, 20% of the total circumference of the head behind the T3 lead. The 02 lead is on the right side of the head, 20% of the total circumference of the head behind the T4 lead. An easy way to remember which side of the head a lead is on is to remember that odd numbered leads are on the left (e.g., 01, C3, T3) and even numbered leads are on the right (e.g., 02, C4, T4).

5. __________is measured in Hertz (Hz) and___________in microvolts (UV). A.Amplitude, frequency B.Amplitude, sensitivity C.Frequency, sensitivity D.Frequency, amplitude Answer: D Explanation: Frequency, or the number of times a wave occurs, is measured in Hertz, or cycles per second. This is the number of times a wave will repeat itself in one second. Voltage is measured in volts, and in polysomnography, in microvolts (UV). Amplitude is a measure of the height of a wave; therefore, the more microvolts, the bigger the wave. Question: 9 In polysomnography, sensitivity is generally measured in A.uV/mm. B.uV/cm. C.uV/in. D.Hz/mm. Answer: A Explanation: Sensitivity is measured in microvolts per millimeter, or uV/mm. What this means is that for each microvolt of a wave, the display will measure it in one mm. This also means that the larger the number of microvolts per millimeter, the smaller the wave will be displayed, because it will take more voltage to change the signal. Question: 10 What is the sensitivity setting for the EEG in a polysomnogram? A.3 uV/mm. B.15 uV/mm. C.7 uV/mm. D.1 uV/mm. Answer: C Explanation: Generally, the sensitivity is set between 5 uV/mm and 9 uV/mm. Of those choices 7 uV/mm would be the best answer. Normally, 1 uV/mm or 3 uV/mm would be far too high of a sensitivity setting (the Visit us athttps://www.certsgrade.com/pdf/brpt-rpsgt/
