Considerations and Approaches For Complex CI Cases

---

1.  Which of the following factors may impact impedance levels in cochlear implants? Device use Hormone levels Electrode placement All of the above

2.  Which of the following programming parameters most closely correlate to electrically-evoked compound action potentials (eCAPs)? Upper comfort levels (C, M, MCL) Threshold levels They don’t correlate with a programming parameter Dynamic range

3.  Which of the following programming parameters most closely correlate to electrically-evoked stapedial reflex thresholds (eSRTs)? Upper comfort levels (C, M, MCL) Threshold levels They don’t correlate with a programming parameter Dynamic range

4.  A patient presents to the clinic complaining of a constant machine-like humming only present when wearing their processor. What is the most likely cause? Elevated microphone sensitivity Over elevated threshold levels Out of compliance electrodes No issue, this is normal operation for the processor

5.  During speech perception testing, a patient consistently misses phonemes associated with |s| and |sh| sounds. Programming changes for electrodes coded for which frequency region will likely have the most impact? Low frequencies Mid frequencies High frequencies None of the above
