  3. Focused Health Assessment • Present Health/Illness Status • numbness, difficulty with speech, vision, hearing, medications, changes in behavior, lifestyle • Family History • headaches, mental illness, depression

  4. Continued: • Past Health History • seizures, headaches • head injury • surgeries • stroke

  5. Equipment Needed: • Cotton ball, safety pin, snellen chart • Tongue blade • Tuning fork • Reflex hammer • pen light • pencil and paper • sweet/sour substances • Familiar aromatic substance (coffee, vanilla)

  6. CN I: Olfactory • Sensory: smell • Apply simple odors to one nostril at a time • Do not test unless history indicates

  7. CN II: Optic • Sensory: vision • Snellen • Visual fields (confrontation) • Ophthalmoscopic examination

  8. CN III: Oculomotor • Motor: upward, downward, medial eye movement • Corneal Light reflex • Cover test • EOM: 6 cardinal positions • Observe lids

  9. CN IV: Trochlear • Motor: downward, medial eye movement • EOM • Same as CN III • Pupillary light reflex • Accommodation

  10. CN V: Trigeminal • Sensory: face, scalp • Motor: • Tactile and pain sensation on entire face

  11. CN VI: Abducens • Motor: lateral eye movement • EOM • Same as CN III

  12. CN VII: Facial • Sensory: • Taste to anterior 2/3 of tongue • Motor: • Ability to frown • Smile, show teeth • Puff out checks • whistle, close eyes

  13. CN VIII: Acoustic • Sensory: • Hearing acuity • Rinne test: on mastoid process • Weber test: on center of forehead • Otoscopic examination • Rhomberg test

  14. CN IX: Glossopharyngeal • Sensory: • Taste • Motor: • Able to swallow • Gag reflex

  15. CN X: Vagus • Sensory • listen to person talk (hoarseness) • Motor • ask person to say “ah” (soft palate contract and uvula stays midline)

  16. CN XI: Spinal Accessary • Motor: • Turn head side to side • shrug shoulders with resistance
