EEG 204 FINAL REVIEW EXAM
WITH 100% CORRECT
ANSWERS 2025
Level of current: "Let go" current for an average child
correct answers >> 3-5 mA
Level of current: Maximum current for a person to grasp
and then let go correct answers >> 16 mA
Level of current: Paralysis of respiratory muscles:
respiratory arrest correct answers >> 20-50 mA
Level of current: Asystole (Heart stops beating) correct
answers >> >2 Amps
Level of current: Maximal intensity of household current
(US) correct answers >> 240 Amps
Level of current: "Let go" current for an average man
correct answers >> 7-9 mA
,Level of current: "Let go" current for an average woman
correct answers >> 6-8 mA
Level of current: Threshold for ventricular fibrilation
correct answers >> 50-100 mA
Level of current: Tetany of skeletal muscles correct
answers >> 16-20 mA
Level of current: Tingling sensation: almost not
perceptible correct answers >> 1 mA
Level of current: Common household circuit breakers
correct answers >> 15-30 Amps
True/False: Birds on electrical lines do not get shocked
because they are not grounded. correct answers >>
True
Factors in electrical injury include: correct answers >>
1. Current intensity
2. Duration of exposure
3. Current pathway
, Critical Systems in the body that are potentially harmed
by electrical injury are: correct answers >> 1. Renal
system
2. Brain and spinal cord
3. Cardiovascular
4. Respiratory
True/False: A stress loop in an electrode lead wire is a
bad idea because it acts as an antenna and picks up
electrical current in the air. It is best to tape down a zig-
zag rather than a loop. correct answers >> True
Average amplitude: ECG or EKG correct answers >>
1.5mV
Average amplitude: Electroencephalogram "EEG"
correct answers >> 20uV
Average amplitude: Sensory Evoked Potentials correct
answers >> 10vV
Average amplitude: Motor Evoked Potentials correct
answers >> 2.5mV
Average amplitude: Electromyogram "EMG" correct
answers >> 3mV
