What is the function of cranial nerve I (Olfactory)?
Sensory: Smell
Test by assessing the sense of smell.
What is the function of cranial nerve II (Optic)?
Sensory: Vision
Test by checking visual acuity.
What is the function of cranial nerve III (Oculomotor)?
Motor: Pupillary reflex, extrinsic muscle movement of eye
Test by checking pupillary response and eye movement.
What is the function of cranial nerve IV (Trochlear)?
Motor: Eye muscle movement
Test by assessing downward and inward eye movement.
What is the function of cranial nerve V (Trigeminal)?
Both: Sensory impulses from face and motor action for teeth clenching.
Test by assessing sensation in different branches and clenching teeth.
What is the function of cranial nerve VI (Abducens)?
Motor: Extrinsic muscle movement of eye
Test by assessing lateral gaze.
What is the function of cranial nerve VII (Facial)?
Both: Facial expression, taste, lacrimation, salivation.
Test by smiling, frowning, and puffing cheeks.
What is the function of cranial nerve VIII (Vestibulocochlear)?
Sensory: Hearing and balance
Test by assessing hearing and balance.
What is the function of cranial nerve IX (Glossopharyngeal)?
Both: Taste, gag reflex, swallowing reflex.
Test by assessing taste and the gag reflex.
What is the function of cranial nerve X (Vagus)?
Both: Innervates muscles for swallowing and talking.
Test by assessing gag reflex and voice quality.
What is the function of cranial nerve XI (Accessory)?
Motor: Movement of trapezius and sternocleidomastoid muscles.
Test by assessing shoulder shrug and head rotation.
What is the function of cranial nerve XII (Hypoglossal)?
Motor: Movement of tongue for swallowing and speech.
Test by assessing tongue movement.
How to test the Biceps reflex?
Use the pointed side of the reflex hammer in the bend of the elbow.
How to test the Triceps reflex?
Use the pointed side of the reflex hammer just above the elbow.
How to test the Brachioradialis reflex?
Use the flat side of the hammer halfway between the elbow and wrist (anterior side).
How to test the Patellar reflex?
Use the flat side of the hammer just below the knee with the patient sitting and leg freely hanging.
How to test the Achilles reflex?
Use the flat side of the hammer against the Achilles tendon while holding the patient’s foot, either sitting or laying.
How to test the Plantar/Babinski reflex?
Scrape the lateral edge of the bottom of the foot starting at the bottom and coming up and then medially.
How to test the Abdominal reflex?
Use a dull object (tongue blade) and scrape all four quadrants of the abdomen towards the navel.
What to assess for increased intracranial pressure (ICP)?
Assess level of consciousness (LOC), motor function, pupillary response, and vital signs.
What is considered elevated ICP?
Elevated ICP is 15-20 mmHg.
What controls the pupils?
Pupils are controlled by cranial nerve 3, brainstem, and midbrain.
What is the normal size and shape of pupils?
Normal size is 3-5 mm, and normal shape is round.
What does fixed dilated pupils indicate?
Fixed dilated pupils indicate increased ICP, prolonged diffuse hypoxia, or atropine.
What do pinpoint pupils indicate?
Pinpoint pupils indicate narcotics.
