Preform the cranial nerve tests to determine if function is normal, consulting table 21.2 for each nerve action. Record results in Table 21.3 by circling either normal (N) or abnormal (A) for each nerve. • Sniff aromatic oil, spice, or coffee grounds (ability to smell is normal) • Read a Snellen eye chart at 20 ft. (ability to read is normal) • Observe eyelids (eyelid not drooping is normal) • Look up, down, medially, laterally, upper lateral, lower lateral (ability to move eyeball is normal) • Shine penlight on pupils (constriction is normal) • Lightly touch the cornea of the subject with a wisp of cotton (blinking is normal) • Subject bites down on tongue depressor; try to pull it out (good resistance to pulling is normal) • Have subject smile, raise eyebrows, whistle, and close the eyes (ability to do these actions is normal) • Check tip of tongue for taste with sugar (ability to taste is normal) • Use a tuning fork to check hearing in each ear (ability to hear is normal) • Have the subject stand straight with eyes closed (absence of swaying is normal) • Have subject say, "Ah"; check uvula position with mouth open (midline is normal) • Using a cotton-tipped applicator, gently touch the subject's uvula to elicit a gag reflex (gag response is normal) • The posterior 1/3 of tongue can be tested with cotton applicator dipped in quinine (taste is normal) • Have subject shrug shoulders against resistance as you are holding them down (both sides having equal strength is normal) • Ask your lab partner to stick out and retract his/her tongue (tongue not deviating to one side is normal)Preform the cranial nerve tests to determine if function is normal, consulting table 21.2 for each nerve action.
