Antidotes
100
This class of antibiotics may produce irreversible cochleo-toxicity by binding to NMDA receptors in the cochlea and damaging neurons.
What are aminoglycosides (ex. gentamicin, tobramycin). Side note: The ototoxicity of gentamicin can be exploited to treat some individuals with Meniere's disease by destroying the inner ear (which stops the vertigo attacks but causes permanent deafness in that ear.)
100
Sexually transmitted infection that when passed to fetus can cause sensorineural hearing loss.
What is syphilis (will also accept chlamydia)
100
Most common cause of hearing loss in the geriatric population.
What is presbycusis.
100
A patient has conductive hearing loss on the right due to cerumen impaction. Weber test will lateralize to which side?
What is the right side.
100
Antidote for opioid overdose.
What is Narcan (naloxone).
200
Diuretic that is associated with ototoxicity.
What is furosemide/Lasix. Usually with large parenteral doses and rapid administration and in renal impairment.
200
Disease characterized by fluctuating sensorineural hearing loss (more prominent in lower frequencies of speech), episodic vertigo, ear pressure, and tinnitus.
What is Meniere's disease.
200
Most common cause of hearing loss in pediatric population.
What is otitis media.
200
A patient has sensorineural hearing loss, L>R, due to excess noise exposure. Rinne test will give this result on the left.
What is AC>BC. In sensorineural hearing loss, bone conduction and air conduction are both equally depreciated, maintaining the relative difference of bone and air conductions
200
Antidote for Tricyclic Antidepressant overdose
What is sodium bicarbonate.
300
Large doses of this common over-the-counter medication can cause reversible tinnitus.
What is aspirin. (will also accept NSAIDS as answer)
300
Common hereditary disease that deposits bone around the footplate of the stapes.
What is otosclerosis.
300
Most common preventable hearing loss.
What is noise-induced hearing loss.
300
Patient presents with right-sided hearing loss secondary to presbycusis. Which side will Weber test lateralize to?
What is the left side. In sensorineural hearing loss, Weber will lateralize to the unaffected ear. This situation is because the affected ear is less effective at picking up sound even if it is transmitted directly by conduction into the inner ear.
300
Antidote for anticholinergic overdose.
What is physostigmine.
400
Chemotherapeutic agent that is associated with cochleo-toxicity characterized by high-frequency hearing loss and tinitus.
What is cisplatin (and carboplatin). Ototoxicity through production of reactive oxygen species.
400
Painful vesicular viral rash affecting the facial nerve unilaterally, with the potential to cause facial paralysis and hearing loss. (Specific name)
What is Ramsay Hunt Syndrome (type 2) or herpes zoster oticus. Treatment with prednisone and acyclovir has been shown to achieve complete recovery in a majority of patients if started within the first three days of facial paralysis, with chances of recovery decreasing as treatment was delayed. Hearing loss is mostly temporary but it may become permanent for some patients.
400
The most common cause of hearing loss in the general population.
What is cerumen impaction.
400
A potential cause of this type of tympanogram. (name any)
What is fluid in the middle ear, perforation of the tympanic membrane, scarring of the tympanic membrane, lack of contact between the conduction bones of the middle ear or a tumor in the middle ear. Type B Tympanogram. Low compliance – less ability for sound to pass through.
400
Antidote for beta-blocker overdose.
What is glucagon.
500
The sound pressure level (SPL) in decibels at which noise can cause permanent hearing loss.
What is 85 decibels (for an eight-hour period). Based on the logarithmic scale, every 3-dB increase in SPL represents a doubling of the sound intensity. Therefore, 4 hours of noise exposure at 88 dB is considered to proide the same noise "dose" as 8 hours at 85 dB. Common sources of noise: Gunshot 140-170 dB; Jet takeoff 140 dB; Motorcycle, lawnmower 90 dB; Conversation 60 dB; Whisper 30-40 dB.
500
Common benign skin cyst that grows slowly in the middle ear and/or mastoid process and destroys adjacent bone as it grows.
What is cholesteatoma.
500
Most common infectious cause of hearing loss recognized at birth.
What is CMV.
500
What type of hearing loss does this audiogram demonstrate.
What is conductive hearing loss.
500
Antidote for ethylene glycol poisoning.
What is fomepizole.
