impedance levels for EEG electrodes?
a. Less then 20,000 ohms
b. Less then 5 ohms
c. Less then 5k ohms
d. At least 20,000 ohms
arm EMG - CORRECT ANSWER - Which of these electrode sites is not typically used in a
baseline montage?
Leg EMG
E2
Arm EMG
Thoracic belt
Recording the differences in the voltages of two inputs - CORRECT ANSWER - Which of
the following is a process performed by a differential amplifier?
a. Recording the differences in the voltages of two inputs
b. Recording the differences in the voltages of the active input and ground
c. Recording the differences in the voltages of an exploring electrode and the patient ground
connection
d. Recording only identical voltages received by its two inputs
hunter-cheyne-stokes breathing pattern - CORRECT ANSWER - Adaptive servo ventilation
is an effective treatment for which of the following disorders?
A.
,Obesity hypoventilation syndrome
B.
Nocturnal asthma
C.
Hunter-Cheyne-Stokes breathing pattern
D.
Congenital central hypoventilation syndrome
increasing the LFF from 0.3 hz to 1.0 hz - CORRECT ANSWER - All of the following may
be helpful in identifying 60-Hz artifact EXCEPT:
a. applying and removing the AC (line) filter.
b. decreasing time base to count the frequency.
c. decreasing the HFF from 70 Hz to 35 Hz.
d. increasing the LFF from 0.3 Hz to 1.0 Hz.
document any changes in recording parameters - CORRECT ANSWER - One of the MOST
important roles of the recording technologist is to:
a. score sleep stages prior to applying treatment
b. document any changes in recording parameters
c. record interpretation of patient comments and actions
d. assure patient completes the pre-sleep questionnaire
increasing sampling rate
why; Advanced digital acquisition systems samples continuous signals at a fixed rate, called a
sampling rate. The Nyquist theorem states that a digital copy of a signal can be completely
reconstructed from samples made at a sampling rate faster than twice the bandwidth of the
highest frequency of the original data. Sampling at a higher rate facilitates more accurate
reconstruction of the signal. EEG spikes, such as those seen in epileptiform activity, require a
,high sampling rate to reconstruct the signal, enhance resolution and improve the definition of the
waveform. - CORRECT ANSWER - What would increase the resolution of EEG spikes and
improve definition of the waveforms?
a. applying 50/60 Hz filter
b. using a 100 uV input voltage
c. increasing sensitivity
d. increasing sampling rate
mild osa - CORRECT ANSWER - The best candidate for oral appliance therapy would have?
a. Moderate RBD
b. End-stage COPD
c. Severe snoring
d. Mild OSA
increased site preparation - CORRECT ANSWER - Which of these factors does not tend to
increase impedances?
a. Increased site preparation
b. Broken/faulty wires
c. Dirty electrodes
d. Poor application
0.5 hz - CORRECT ANSWER - Which of these LFF settings is preferred for and EEG
channel?
0.5Hz
3.0Hz
10Hz
35Hz
, hyperactivity - CORRECT ANSWER - Obstructive apnea is pediatric patients is most often
associated with:
a. Idiopathic hypersomnolence
b. Hypothyroidism
c. Hyperactivity
d. Overlap syndrome
increased site preparation - CORRECT ANSWER - Which of these factors does not tend to
increase impedances?
a. Increased site preparation
b. Broken/faulty wires
c. Dirty electrodes
d. Poor application
shorter power cords - CORRECT ANSWER - Which of these does not tend to increase
leakage current?
a. Shorter power cords
b. Power strips
c. Battery backups
d. Parallel placement of wires
Measure the patient's ability to resist the urge to fall asleep - CORRECT ANSWER - The
most important reason for performing a MWT is to:
a. Calculate the total sleep time over 5 nap opportunities
b. Differentiate narcolepsy form idiopathic hypersomnia
c. Measure the patient's ability to resist the urge to fall asleep
d. Predict the need for administering stimulant medicaiton
