Allow the patient to wear their glasses during this test.
The nurse can also test this cranial nerve by allowing the patient to read a book.
This is how the nurse assesses what cranial nerve?
Cranial Nerve II – Optic
Rationale: Allow the patient to wear their glasses because you are not testing their vision that is controlled by the lens. You are testing the nerve.
Assess this nerve by poking the face with something sharp and then something dull with the patients eyes closed.
Then have the patient tell you where you placed the item and whether it was sharp or dull.
This is how the nurse assesses what cranial nerve?

This is the sensory nerve that allows us to see.
What cranial nerve does this indicate?
Cranial Nerve II – Optic
Checking the Gag Reflex

This is how the nurse assesses what cranial nerve?
Cranial Nerve VIII – Acoustic
Assess the corneal reflex with a cotton whisp to the open eye.
DO NOT use this assessment on an alert and oriented patient.
This is how the nurse assesses what cranial nerve?
Cranial Nerve V – Trigeminal
This is the sensory nerve that gives us our sense of smell.
What cranial nerve does this indicate?
Cranial Nerve I – Olfactory
The ______ of sensory tract and motor tract allows us to feel the things around us and conduct a motor response. Not all nerves have both sensory and motor components, some have ONLY sensory functions and some have ONLY motor functions.
Combination
REMEMBER THIS IT IS IMPORTANT!
This is the sensory nerve that allows us to hear. This nerve also innervates 1/3 of the posterior tongue with taste sensations. What cranial nerve does this indicate?
Cranial Nerve VIII – Acoustic
This is called the _______ because it has three branches. The_______ branch innervates the eyes, forehead, and nose area of the face, the _______ branch innervates the upper lip, nose, and temples area of the face and the ______ branch innervates the bottom lip and chin areas of the face.
Cranial Nerve V – Trigeminal Nerve
Mandibular
Ophthalmic
Maxillary
Study Tip: At the dentist they inject the anesthetic to affect the mandibular and maxillary branches of these nerves. The eye muscles can become numb as well if the medication can affects the branches of this nerve accidentally because of this branching system which will cause the muscles around your eye to be affected by the local anesthesia because of this nerve being affected.
This is the motor nerve that controls the tongue muscles.
What cranial nerve does this indicate?
Cranial Nerve XII – Hypoglossal
Which lobe in the brain is integrating with Cranial Nerve II so that the patient can tell you what they are seeing?
The Occipital Lobe
Rationale: Cranial Nerve II – Optic
This is the sensory and motor nerve that allows the facial muscles to make facial expressions.
What cranial nerve does this indicate?
Cranial Nerve VII– Facial
Occulomotor/Motor/ Eyeball Movement/Pupil Constriction/ Opens Eyelid
What cranial nerve does this indicate?
Cranial nerves III
Abducens/Motor/Eyeball Movement
What cranial nerve does this indicate?
Cranial Nerve VI
Left side of the face does not react like the _____ side. This causes paralysis of Cranial nerve ______ which usually affects only one side of the face. This occurs usually after a _____ infection. You can regain your function but you will never be 100% function. This is commonly misdiagnosed as a ______.
This indicates that your patient has what disorder?
Right
Cranial Nerve VII/Facial
