Cranial Nerves
I-VI
I-VI
Is responsible for lateral movement of the eye
CN VI or Abducens
Is responsible for shoulder movements and turning head
CN XI, Spinal Accessory
Asking the patient who the current president is can be a way to assess this
General fund of knowledge
This test observes the flow of dye through the subarachnoid space
Myelogram
Be sure to assess patient's baseline of lower extremity strength and sensation both prior and after the procedure
These are the two main divisions of the nervous system
Central nervous system and peripheral nervous system
Is responsible for sense of smell
CN I, Olfactory
Is responsible for sensations of throat, larynx, thoracic and abdominal organs; peristalsis
CN X, Vagus
These types of questions are the best to get a valid response from a patient
Open ended questions allowing the patient to describe the answer
In this test the patient receives an injection of deoxyglucose mixed with radioactive fluorine
Positron Emission Tomography Scan or PET Scan
Chemicals that modify or result in transmission of impulses between synapses
Neurotransmitters
Is responsible for pupillary control and blinking
CN III, Oculomotor
Is responsible for tongue movements
CN XII, Hypoglossal
This is how FOUR Score Coma Scale is different than Glasgow Coma Scale
The category scores are NOT totaled, so there is not a sum score
This is how to assess a post-lumbar puncture patient
Assess for leakage/moisture on bandage or around the puncture site; assess for pain, numbness, and tingling in the extremities
What is the first autonomic nervous system event that takes over in times of stress to prepare the body for "fight or flight"
Sympathetic nervous system domination
Is responsible for vision
CN II, Optic
Is responsible for sense of taste on anterior 2/3 of tongue, muscle contraction for facial expression
CN VII, Facial
The Glasgow Coma Scale score for a patient that:
Opens eyes to pressure
No verbal response
Withdraws in response to pain
Eyes to pressure: 2
No verbal response: 1
Withdraws in response to pain: 4
Total score: 7
Any score on the Glasgow Coma Scale of 8 or fewer commonly is accepted as a definition of coma
Procedure used to visualize cerebral arterial system with radiopaque dye; can detect arterial aneurysms, vessel anomalies, ruptured vessels, and displacement of vessels by tumors or masses
Angiogram (Cerebral arteriography)
These are all normal neurologic changes related to aging
Slower reaction time, tremors in hands when fatigued, trouble with small intricate tasks
Is responsible for sensations of the face, scalp, and teeth; chewing movements
CN V, Trigeminal
Is responsible for sensations of throat, swallowing, gag reflex, secretion of saliva, taste on posterior 1/3 of tongue
CN IX, Glossopharyngeal
The definition of proprioception
The body's sense of its own position and limb movements without looking at it; being able to recognize objects by the sense of touch
This is why a lumbar puncture is performed
To obtain CSF for testing; to relieve pressure; to introduce dye or medication
Before any type of diagnostic scan using dye, it is imperative to assess for this
Allergies to iodine, shellfish, or dyes
