| Question | Answer |
|---|---|
| A lesion is present in the inner ear and the VIII N. This is which type of hearing loss? | sensorineural |
| Tubes that are closed at one end (like the ear canal) resonate to a frequency | That has a wavelength 4 times the length of the tube |
| Cerumen is formed from | sebacious glands, arocrine glands, eccrine glands, cellular debris/ hair |
| Using audiometry is has been determined that your bone conduction thresholds are normal, but if you have a 40dB loss by air conduction. This type of hearing loss you have is | conductive (using audiometry) |
| Using an otoscope you could | observe the cone of light |
| If the audiogram shows a hearing loss, you | could have a normal tympanogram |
| A doorbell is judged to be equally loud as a 1000-Hz tone at 65 dB SPL. A dog barking has a loudness of 75 phones. You conclude that | the dog is about twice as loud as the doorbell |
| Using audiometry it has been determined that your bone conduction thresholds show a 30 dB hearing loss, and you have a 50 dB loss by air conduction. The type of hearing loss you have is | mixed |
| The child has a sensorineural hearing loss. Which tympanogram type would you predict? | Type A (normal peak admittance, normal middle ear pressure) |
| Earwax | normally is externalized by the growth pattern of tissue in the ear canal |
| The pH of the tissue lining the ear canal is higher than normal | making an external otitis more probable |
| An ear infection caused by bacteria is | an acute otitis |
| The cone of light is considered to be associated with the | eardrum |
| A lesion is present in the outer ear and the middle ear. This is which type of hearing loss? | conductive (lesion is present) |
| The ear canal is "S" shaped. | protecting the eardrum from objects inserted into the canal |
| Hearing screening (for children 6 years and older) is designed to detect hearing loss greater than? | 20 dB, but only for frequencies at and above 1000 Hz |
| There are two middle ear muscles | the tensor tympani and the stapedius muscle |
| The cochlea is fluid filled and contains the | membranous labyringth |
| The difference between performing hearing screening on an adult (> 18 years of age) and children is that | adults need to be screened at 25 dB HL |
| What are the risk factors for middle ear disease? | attendance in day care programs, bottle feeding babies, exposure to second hand smoke |
| On the initial screen an 8 year old has compliance (Ytm) of 0.2 mmho and tympanometric width of 300 daPa, so you recommend | retesting in 6 - 8 weeks |
| The automated ABR and OAEs are | procedures recommended for screening neonates |
| Which condition would allow in phase sound to strike the oval and round window simultaneously? | a perforation |
| The part of the eardrum where cholesteatomas often begin to grow is | in the pars flaccida |
| Long standing secretory otitis media | increases chances that a cholesteatoma might develop, may have adverse effects upon speech-language development, should be treated with tympanostomy tubes |
| Removing hair cells would result in | sensorineural hearing loss |
| The elastic pressure release for inward motions of the footplate of the stapes | is found in outward movement of the round window |
| Cytomegalovirus (CMV), syphilis, and rubella | are all causes of prenatal or perinatal hearing loss |
| Ménière's disease and central presbycusis are both similar in that | a type A tympanogram should be found |
| The structure important for shearing the hair cell stereocilia is the | tectorial membrane |
| The organ of Corti | is about 3 mm long, is located in scala media, is located within the membranous labyrinth |
| A hearing loss caused by ingestion of an aminoglycoside antibiotic is | ototoxicity |
| Endolymph is contained within | the membranous labyrinth |
| The auditory brainstem response (ABR) | is abnormal, often absent, when a tumor is present in the internal auditory meatus |
| If you were to lose all of your outer hair cells | there would be about a 40 to 50 dB hearing loss |
| Within the cochlea, high frequencies are analyzed | at the basal end |
| If a 100 Hz tone is delivered to the ear and individual nerve fibers fire 100 times per second, this is | an explanation of how low frequency tones are perceived, by temporal activity in the cochlear nerve |
| As the traveling wave moves down the organ of Corti | it moves from the basal end to the apical end of the cochlea |
