AND ANSWERS SURE A+
✔✔What is glaucoma? - ✔✔A condition characterized by elevated intraocular pressure
(IOP) that damages the optic nerve, often asymptomatic until vision loss occurs.
✔✔What is the primary treatment for glaucoma? - ✔✔Life-long eye drops to lower
intraocular pressure.
✔✔What are cataracts? - ✔✔Cloudiness of the lens resulting in painless, blurry vision
and sensitivity to glare; surgical removal is the only cure.
✔✔What is vertigo? - ✔✔An illusion of motion (spinning); nursing priority is fall
prevention.
✔✔What is otosclerosis? - ✔✔Fixation of the stapes bone, causing progressive
conductive hearing loss.
✔✔What is ototoxicity? - ✔✔Hearing loss or tinnitus caused by medications like
aminoglycosides or aspirin.
✔✔What does the whisper test assess? - ✔✔It provides a general estimate of a
patient's gross auditory acuity.
, ✔✔How is the whisper test performed? - ✔✔The examiner covers the patient's untested
ear and whispers from 1 to 2 feet away from the unoccluded ear.
✔✔What indicates normal hearing in the whisper test? - ✔✔A patient correctly repeats
the whispered phrase.
✔✔What is audiometry? - ✔✔The single most important diagnostic instrument for
detecting and quantifying hearing loss.
✔✔What are the two types of audiometry? - ✔✔Pure-tone audiometry and speech
audiometry.
✔✔What does pure-tone audiometry measure? - ✔✔The loudness of musical tones
perceived by the patient to determine the degree of hearing loss.
✔✔What does speech audiometry assess? - ✔✔The patient's ability to hear and
discriminate between different sounds and words.
✔✔What is frequency in the context of hearing? - ✔✔Measured in Hertz (Hz), it refers to
the number of sound waves per second, with human perception generally between 20
and 20,000 Hz.
✔✔What is pitch? - ✔✔A description of frequency, where 100 Hz is low pitch and
10,000 Hz is high pitch.
✔✔What does intensity refer to in hearing? - ✔✔Measured in decibels (dB), it refers to
the loudness or pressure exerted by sound.
✔✔What is an audiogram? - ✔✔A graph that plots the results of audiometry to
differentiate between conductive and sensorineural hearing loss.
✔✔What is a perforated eardrum? - ✔✔A condition typically caused by infection or
trauma, leading to reduced hearing ability.
✔✔What are common causes of tympanic membrane perforation? - ✔✔Trauma, such
as skull fractures or foreign objects, and infections that increase pressure in the middle
ear.
✔✔What is the typical healing process for a perforated eardrum? - ✔✔Most perforations
heal on their own within a few weeks, though some may take several months.
✔✔What is tympanoplasty? - ✔✔A surgical procedure to repair a perforated eardrum if
it does not heal spontaneously.
