Self-assessment
All 35 self-assessment questions from across the atlas, grouped by module and tagged by level (Foundation, Trainee, Clinician). Each set scores as you reveal answers; read every rationale, including the incorrect options. For applied vignettes, work the case library; for a measure-by-measure overview, see Compare.
Module 2 · Impedance & electrode interface
Which stimulation mode normally gives the lowest impedance values and is the clinical default?
An abnormally LOW impedance on a contact most suggests:
Which objective measure can flag an electrode-array tip fold-over without imaging?
Module 3 · ECAP / Neural Response Telemetry
The N1 peak of the ECAP is generated by:
Forward-masking subtraction removes the stimulus artifact by exploiting:
Compared with the acoustic CAP, the ECAP is larger and earlier mainly because:
Module 4 · ECAP threshold & functions
The ECAP threshold is most correctly obtained by:
A steep amplitude growth function slope is generally interpreted as indicating:
A broad spread-of-excitation function indicates:
Module 5 · Electrical stapedius reflex
The electrical stapedius reflex is most useful for anchoring which part of the MAP?
Post-operatively, the electrical stapedius reflex is typically recorded with immittance equipment in the:
Why are intra-operative ESRTs generally higher and more variable than awake post-operative values?
Module 6 · Electrically-evoked ABR
Compared with the ECAP, the eABR primarily adds information about:
The most robust and clinically used peak of the eABR is:
In which scenario is the eABR most valuable?
Module 7 · Electrical cortical responses
The P1 cortical response in implanted children is used as a biomarker of:
Compared with the eABR, recording cortical responses (CAEPs) usually requires the patient to be:
The P1 evidence base contributed to which change in clinical practice?
Module 8 · Intraoperative ECochG
Intraoperative ECochG during CI surgery primarily aims to:
The workhorse signal monitored during insertion is the:
An abrupt ~30–40% drop in CM amplitude during insertion should prompt:
Module 9 · Objective measures → the MAP
Which objective measure best anchors the comfortable-level (C/M) ceiling of a MAP?
Why is the ECAP threshold better used as a profile than as an absolute value?
A MAP built purely on objective measures should be regarded as:
Module 10 · Troubleshooting & special cases
In suspected device soft failure, the most informative objective evidence is usually:
Loud-sound-triggered facial twitching after activation most likely represents:
In cochlear nerve deficiency, a present, replicable eABR supports:

NRT, ART, and NRI are three manufacturers' names for systems that record:
Which is true about level values across manufacturers?
Cochlear's AutoNRT obtains ECAP thresholds primarily using:
Which statement about the cochlear-implant manufacturer landscape is correct?
Module 13 · Future directions, AI & emerging tech
AutoNRT, which finds ECAP thresholds automatically, is an early clinical example of:
Panoramic ECAP (PECAP) is being developed primarily to:
A multicentre trial supported which of these as non-inferior to in-person care?
Why will an optogenetic cochlear implant need a new objective-measures toolbox?
