Evoked Potential 101 Series - Click ABR

---

1.  Which of the following statements about click rate is true? Stimulus rate has no impact on ABR waveform data A rate of 1.1/sec is ideal for click-evoked ABR testing Faster click rates prolong test time As click rate increases, the latency of ABR waveform peaks also increases

2.  An analysis window of approximately 10 milliseconds is ideal for click ABR threshold assessment on infants. True False

3.  A reasonable low pass filter setting for ABR based on the known frequency content of an ABR is: 3000 Hz 30 Hz 300,000 Hz 1500 Hz Both A and D

4.  Alternating polarity used during ABR testing will help to: Increase the amplitude of Wave V Allow you to obtain ABR response closer to true behavioral threshold Reduce the presence of stimulus artifact at high intensities None of the above

5.  A response collected from the contralateral recording channel can assist with accurate peak-picking of Wave V in the ABR. True False
