Diagnostic ABR: Tips from the Trenches - Difficult to Test Populations in Difficult Test Environments, presented in partnership with Cincinnati Children's

---

1.  Which technology options are advantageous when dealing with electrical or myogenic interference during ABR testing? Weighted signal processing Noise reduction coefficient Statistical analyses (le correlation coefficient, fsp) All of the above

2.  Evidence shows this strategy helps infants achieve a deeper and longer sleep state and reduces the amount of muscle movement: Rocking Patting Swaddling Sleeping in parent/caregivers arms

3.  In the EHDI process, which of the following can help reduce loss to follow-up during the identification process: Obtaining complete diagnostic information in one test session Scheduling additional appointments (when needed) with the family before they leave the clinic Utilizing technology which allows testing to be completed in difficult environments. All of the above

4.  Conditions that can impact diagnostic ABR testing for medically complex hospitalized infants include: Electrical interference from multiple sources of medical equipment Increased infant and environmental noise due to tracheostomies, ventilators, stridor etc. Positioning restrictions Infants with sensory integration issues due to repeated painful procedures All of the above.

5.  The number of medically complex infants requiring extending hospital admissions after birth and diagnostic audiologic assessment on an inpatient basis is: Decreasing Increasing Remaining consistent Doesn't really matter because audiologists only do diagnostics on an outpatient basis

6.  A child with autism must be sedated or anesthetized for an ABR if: unable to keep his eyes closed body weight is greater than 30 pounds unable to complete an audiogram with play audiometry unable to tolerate placement of electrodes and earphones

7.  What sources of ambient noise are most problematic? Continuous machine "hum" Brief, quiet conversations between care providers Multiple conversations nearby A and C above

8.  What changes to the ABR occur when inhalant anesthetics are used? Absolute latencies of I, Ill, and V are significantly delayed Absolute latencies of ill and V may be delayed Wave amplitudes increase No changes occur

9.  What can be done to minimize the effects of electricity in the environment? Turn off unnecessary equipment in the room Use evoked potential equipment that uses wireless technology Change the amplifier filter settings to eliminate low frequencies All of the above

10.  Which of the following can be done simultaneously with an ABR under anesthesia? Tonsillectomy Echocardiogram Cleft palate repair C-line placement
