NBC-HIS Prep question and answers
Most common cause of hearing loss at 4000 Hz - -Acoustic Trauma
-A mother comes in worried her hearing is worse since the birth of her first kid what is likely
happening - -Otosclerosis
-A large dip in the 6000Hz in only one ear with positive tone decay is indicative of - -Possible
retro-cochlear tumor
-Patient comes in complaining his hearing aids worked fine until they were cleaned, now they
are weak and feeding back what is the likely cause of this problem - -Receiver tubing is pushed
in
-How does an osteoma present - -Bony growth in external auditory canal
This is a correct answer
-Which validation method can be effectively performed in a sound field envoirnment? - -NU-6
-Which sound field test determines the benefit of directional microphones - -QuickSIN
-acoustic impedance - -resistance a material provides to the passage of sound waves
-During otoscopic inspection what is not a contraindication - -Compliance of the tympanic
membrane
-What two thing verifies an audiogram - -SRT and PTA have to agree (Must be within 5-10
decibels of each other
-A patient brings his hearing aids in to be cleaned and sets them on the counter what type of
transmission should the receptionist be concerned about - -Indirect Transmission
-A patient comes in for a hearing evaluation otoscopy was clear and the results showed
symmetrical precipitous high frequency hearing loss what type of coupler should be used - -
Open-dome
-A patient comes in for a second follow-up and complains that sounds like the furnace and the
fans are too loud and annoying which feature should be adjusted? - -Expansion
-Extending a receiver tubing past the isthmus will have what effect - -Give more high
frequencies give more power help with feedback and wax
-What does the microphone do in a hearing aid - -Transducer that changes acoustic energy-
electrical wave form
