What is the most common cause of Vertigo? Pg.1279 Common cause: vestibular neuritis 50% of cases report a prior cold before vestibular neuritis development
What is the most widely diagnosed Vertigo? Pg.1279 Common type of Vertigo: Benign paroxysmal positional vertigo (BPPV) caused by disruption of the orientation of ear otoliths 42% of vertigo are diagnosed with BPPV
What is the most common variant in colorblindness? Pg.1279 Most common variant: red & greens Less common: blue & yellow

What is the most overlooked abnormality? Pg.1279 a) Vertigo b) Taste disturbances c) Color blindness d) Impaired olfactory function b) Taste disturbances
Ear and Hearing assessment. How do you preform the Weber test? Pg.1292 Place vibrating tuning fork on the midline vertex of client's head. Ask client if sound is equal
Ear and Hearing assessment. How can you tell if a Weber test is normal? Pg.1292 Sound is normally heard equally in both ears
Ear and Hearing assessment. What are abnormal results in a Weber test? Pg.1292 1. Louder on impaired side with conductive hearing loss & Softer on impaired side with sensorineural hearing loss. 2. Conductive hearing loss causes: cerumen build-up, infection otitis media), perforation of eardrum
Ear and Hearing assessment. What are the life span considerations for Weber and Rinne test? Pg.1292 1. Will not be able to perform until school age due to the need for cooperation 2. Consider clapping or alt. noise maker & observe if child looks for source. In clients with autism sudden loud noises are perceived as painful & result in strong response
Ear and Hearing assessment. How do you preform the Rinnie test? Pg.1292 Place the base of the vibrating tuning fork on the clients mastoid bane. Ask client to indicate when sound is no longer heard. The move tuning fork close to ear canal. Ask client to indicate when sound is no longer heard. Repeat on opposite side.
Ear and Hearing assessment. How can you tell if a Rinnie test is normal? Pg.1292 The client with no conductive hearing loss will hear the sound twice as long by air conduction as by bone conduction. Normal pattern AC>BC (air conduction greater than bone conduction)
Ear and Hearing assessment.What are abnormal results in a Rinnie test? Pg.1292 Bone conductions is greater than air conduction in the ear with a conductive loss.
Ear and Hearing assessment. How do you preform the Whisper test? Pg.1292 Ask client to occlude one ear with finger, stand 1-2 feet away on the unoccluded side, softly whisper numbers & ask client to repeat. Repeat on opposite side. Note whether you have to raise voice or stand closer.
Ear and Hearing assessment. How can you tell if a Whisper test is normal? Pg.1292 The client should be able to repeat the numbers or words whispered by the nurse without difficulty.
Ear and Hearing assessment. What are abnormal results in a Whisper test? Pg.1292 This test provides a rough estimate of hearing loss
Ear and Hearing assessment. What are the life span considerations for Whisper and Tympanogram? Pg.1292 Maybe difficult to perform on young children, because it requires understanding of the words spoken and cooperation
Ear and Hearing assessment. How do you preform the Tympanogram test? Pg.1292 Tampanogram is used to measure the pressure in the middle ear & observe the tympanic membranes response to waves of pressure. Ask client not to speak, move, swallow or jump during test.
Ear and Hearing assessment.How can you tell if aTympanogram test is normal? Pg.1292 Normal pressure within the middle ear is 100daPa
Ear and Hearing assessment. What are abnormal results in a Tympanogram test? Pg.1292 Fluid in middle ear, perforated ear drum, impacted earwax, or a tumor of the middle ear
What are two common eye charts used to test for nearsightedness? Pg.1285 Snellen or E chart
