ask patient to read reading material held 36”from face

PERRLA- pupils equal round, reactive to lightand accommodation. Reactionto light· Use pen light and approach from the side, shinelight on the pupil, observe response, pupil should constrict· Shine the light on the pupil again and observeresponse. The other pupil should also constrict Reactionto accommodation· Ask patient to look at a near object then at adistant one and alternate and then move an object towards the patient’s nose.· Eyes should converge when looking down towardthe nose· Eyes should constrict with near object anddilate when looking at the far object· PERRLA- pupils equal, round, reactive to lightand accommodation

Hold apen light 1 ft. in front of patient’s eyes. Ask the patient to follow themovement of the pen light with eyes only. Movethe penlight up, down, side to side and diagonally. Ptshould be able to follow penlight with eyes as it moves.

Assessment Cranial Nerve V

Back 17

Elicitblink response. To testlight sensation, have client close eyes, wipe a wisp of cotton over the clientsforehead. To testdeep sensation, use alternating blunt and sharp ends of an object. Determinesensation to warm and cold object by asking client to identify warmth andcoldness of items§ Patientshould have a (+) corneal reflex, be able to respond to light and deep sensation and be able to differentiate betweenhot and cold§ Inspectfor symmetry, atrophy and tremors. Palpatejaw muscles for tone and strength. Evaluatebite strength

Hold apen light 1 foot in front of pt’s eyes. Ask patient to follow movements witheyes only. Move penlight through 6 cardinal fields of gaze Botheyes should be coordinated , move in unison, with parallel alignment

Smile/frown

Puff cheeks

Wrinkle forehead

Show teeth

Purse lips· Raise eyebrows· Squeeze eyes shut· Say “B”, “M”, “P”· Evaluate taste and differentiate between sweetAnd salty

Whisper test, Weber Test, Rinne Test, assess gait for balance

Front 21

Whisper test

Back 21

1) Stand 1-2 feet behind client so they cannot read your lips. 2) Instruct client to place one finger on tragus of left ear to obscure sound. 3) Whisper word with 2 distinct syllables towards client's right ear. 4) Ask client to repeat word back. 5) Repeat test for left ear. 6) Client should correctly repeat 2 syllable word.

Front 22

Weber Test

Back 22

1) Distinguishes between conductive and sensorineural hearing. 2) Strike a 512 Hz tuning fork softly 3) Place the vibrating fork on the middle of the client's head 4) Ask client if the sound is heard better in one ear or the same in both ears A) If hearing is normal, the sound is symmetrical with no lateralization B) Sound localizes toward the poor ear with a conductive loss C) Sound localizes toward the good ear with a sensorineural hearing loss

Front 23

Rinne Test

Back 23

1) Test compares air and bone conduction hearing. 2) Strike a 512 Hz tuning fork softly. 3) Place the vibrating tuning fork on the base of the mastoid bone. 4) Ask client to tell you when the sound is no longer heard. 5) Note the time interval and immediatly move the tuning fork to the auditory meatus. 6) Ask the client to tell you when the sound is no lonnger heard.. 7) Note the time interval and findings A) Normal hearing clients will note air conduction twice as long as bone conduction B) With conductive hearing loss, bone conduction sound is heard longer than or equally as long as air conduction C) With sensorineural hearing loss, air conduction is heard longer than bone conduction in affected ear, but less than 2:1 ratio
