20Q: The Cross-Check Principle in Pediatric Audiometry - Forty Years Later

---

1.  What is an example of the cross-check principle? Comparing your audiogram to an audiogram from another facility. Comparing electroacoustic test box measurements between right and left hearing aids. Comparing ABR findings with immittance measurements. Comparing otoscopy with an outcome questionnaire.

2.  Who published the sentinel paper on the cross-check principle? Jerger & Hayes Jerger & Martin Sharma & Hayes Kraus & Mueller

3.  Which of the following is not a subject-related variable on the click-evoked ABR? Site of auditory dysfunction Age Gender Degree and configuration of hearing loss

4.  What hallmark findings are associated with classic auditory neuropathy spectrum disorder? Normal ABR wave V latency with increased inter-peak latencies Absent OAEs with normal pure-tone thresholds Robust cochlear microphonic with absent neural findings Absent acoustic reflexes and absent ABR wave V

5.  What does the Sensitivity Prediction by the Acoustic Reflex (SPAR) test compare? Acoustic reflexes of pure tones to acoustic reflexes of broadband noise Acoustic reflexes of running speech to acoustic reflexes of spondee words Acoustic reflex decay of right versus left ears Presence of acoustic reflexes to the presence of OAEs

6.  In which of the following situations do OAEs have clinical utility? Newborn hearing screenings Monitoring ototoxicity Diagnostic component for auditory neuropathy spectrum disorder All of the above

7.  Recent research has shown that wideband acoustic immittance is a better predictor of what? Serous effusions that will cause hearing loss Presence of DPOAEs Normal hearing thresholds Effusions that will clear without antibiotic treatment

8.  Historically, immittance testing for both infants and adults was done using a: low frequency probe tone high frequency probe tone mid frequency probe tone pink noise probe tone

9.  According to this article, behavioral testing of a pediatric patient should begin: In the booth with a video reinforcement system As soon as the child stops crying after otoscopy In the waiting room when the child is playing and interacting After the child is comfortable with headphones

10.  A pediatric audiologist should be able to observe: auditory, speech-language, and cognitive development auditory, psycho-social and emotional development auditory and visual impairments auditory impairment only
