NURS 507 neuro
Assessment -neuro/cranial nerves
| Question | Answer |
|---|---|
| CN I | S---olfactory----smell, nasal epithelium |
| CN II | S---optic---vision, retina |
| CN III | M---oculomotor---EOM---up/down/medial ---and PUPILARY CONSTRICTION |
| CN IV | M---trochlear---EOM---down/medial |
| CN V | S/M---trigeminal---face/scalp sensations---muscles of mastication |
| CN VI | M---abducens----LATERAL eye movement |
| CN VII | S/M---facial----taste anterior 1/3---facial expression/movement |
| CN VIII | S/M---Aucuoustic (vestibular/equilibrium---cochlear/hearing) |
| CN IX | S/M---glossopharyngeal---taste posterior 1/3---gag/swallow/saliva |
| CN X | S/M---vagus---gag/swallowing---muscles of pharnyx/larynx/esoph/soft palate---psymp chemoreceptors, baroreceptors |
| CN XI | M ---accessory---swallowing---SMC (sternocleidomastoid) & trapezius |
| CN XII | M---hypoglossal---swallowing/tongue movement/talking |
| how do we test CN I | smell soap, coffee, etc. |
| how do we test CN II | controls central & peripheral vision ---have them read or count # of fingers being held up---peripheral vision test |
| peripheral vision tests for what CN | CN II optic |
| how do we test CN III | pupilary response to light |
| When we do PERRLA, what CNs are we testing? | CN III pupilary response---CN IV accomodation test |
| how do we test CN IV | accomodation test to check down/medial EOM |
| When we check for ptosis, what CN | CN III by checking where eyelid falls on pupil |
| If a pt has a problem with CN V, where would it show up? | on their forehead---cheek---jaw |
| To test sensory fx of CN V, what would you do | check their scalp, forehead, cheek and jaw for sensations |
| to test motor fx of CN V, what would you do | test motor function of temporal & masseter muscles by assessing jaw opening strength |
| if I suspect a problem with CN VI and VII, what should I do | check corneal reflex with cotton wisp |
| how do I test CN VI | EOM lateral tested by 6 cardinal fields of gaze |
| how do I test CN VIII for hearing aspect | rub my fingers together next to pt ear |
| how do I test for CN VII | assess for facial symmetry---close eyes/smile/pucker/show teeth/puff cheeks----when smiling observe nasolabial folds for weakness/flattening |
| How do I test CN IX and X | taste on posterior 1/3---ability to swallow---gag reflex---Ahhh test palate should rise/uvula midline |
| How do I test CN XI | place hands on pt shoulders, ask them shrug (trapezius)---ask pt to turn head against my hand (SCM) |
| How do I test for CN XII | stick out tongue, midline. problems eating/swallowing/chewing-----also assess with CN IX and X |
| EOMs tested by 6 cardinal fields of gaze, specifically test which CNs | CN III, IV and VI |
| rooting reflex | CN V |
| response to loud noise---startle---blink---looking for noise with eyes or turning head ---all are responses for which CN | CN VIII |
| gag reflex---coordinated suck/swallow while feeding (also cerebellar fxn) uses what CNs | CN IX, X and XII |
