Fast Fourier transformation
determines the time domain of the raw EEG
uses the zero-crossing frequency
is the mathematical transformation of a complex waveform into simpler, more uniform waves
is a function of the spectral edge ✔Correct Answer-is the mathematical transformation of a
complex waveform into simpler, more uniform waves
EEG waves with a frequency of 5 Hz can be classified as what type of EEG?
alpha activity
beta activity
delta activity
theta activity ✔Correct Answer-theta activity
When monitoring with SSEPs, dural or direct cord recordings are advantageous because
they present less discomfort to the patient than scalp leads
they have less chance of artifact during cauterization
the waveforms better reflect cortical responses to stimulation
the waveforms are higher in amplitude and require fewer averages ✔Correct Answer-the
waveforms are higher in amplitude and require fewer averages

delta activity
alpha activity
beta activity
intermittent theta ✔Correct Answer-delta activity
If the surgeon's arm unknowingly brushes an undraped microscope
Inform the surgeon
,Ask the circulating nurse to clean and drape the microscope
Place a sticker marked (contaminated) on the microscope
There is no need for any action ✔Correct Answer-Inform the surgeon
The use of the 60 Hz notch filter is discouraged while recording because it can
produce a risk to the patient
produce ringing activity that can contaminate the appearance of the response
cause the recording electrodes to form a salt bridge
filter slow activity, distorting the response ✔Correct Answer-produce ringing activity that can
contaminate the appearance of the response
When bringing equipment to a hospital for the first time
all cords should be immersed in disinfectant
the equipment should be draped within a sterile cover
