cranial nerves - test

I - close eyes, place something familiar for the patient to smell and identify (orange/lemon peel, coffee, or vinegar) under each nostril alone
II
- acuity - snellen chart with and without visual aids
- colour - ishihara plates identify patients who are colour blind
- fields - asking the patient to look directly at you whilst you wiggle one of your fingers in each of the four quadrants; ask the patient to identify which finger is moving; inattention can be tested by moving both fingers at the same time and checking the patient identifies this
- reflexes - place one hand vertically along the patients nose to block any light from entering the eye which is not being tested; shine a pen torch into one eye and check that the pupils on both sides constrict; tested on both sides
- fundoscopy - performed on both eyes
III / IV / VI - head perfectly still directly in front of you, you should draw two large joining H’s in front of them using your finger and ask them to follow your finger with their eyes; the patient does not move their head
V
- sensory - lightly touching the face with a piece of cotton wool followed by a blunt pin in three places on each side of the face: around the jawline, cheek, forehead; corneal reflex - lightly touching the cornea with the cotton wool; should cause the patient to shut their eyelids
- motor - ask the patient to clench their teeth together, observing and feeling the bulk of the masseter and temporalis muscles; open their mouth against resistance; jaw jerk on the patient by placing your left index finger on their chin and striking it with a tendon hammer - cause slight protrusion of the jaw
VII - asking the patient to crease up their forehead (raise their eyebrows), close their eyes and keep them closed against resistance, puff out their cheeks and reveal their teeth
VIII
- Rinne test - place a sounding tuning fork on the patient’s mastoid process and then next to their ear and ask which is louder; normal patient will find the second position louder
- Weber’s test - place the tuning fork base down in the centre of the patient’s forehead and ask if it is louder in either ear; should be heard equally in both ears
IX - tested with the gag reflex or by touching the arches of the pharynx
X - asking the patient to speak gives a good indication to the efficacy of the muscles; uvula should be observed before and during the patient saying “aah”; check that it lies centrally and does not deviate on movement
XI - ask the patient to shrug their shoulders and turn their head against resistance
XII - observe the tongue for any signs of wasting or fasciculations; ask the patient to stick their tongue out; if the tongue deviates to either side, it suggests a weakening of the muscles on that side
