1. What are the three divisions of the nervous system?: -Central Nervous
System ( CNS)
-Peripheral Nervous System (PNS)
-Autonomic Nervous System (ANS)
2. What is the function of the CNS?: -Receive and process sensory
information
-Create responses to be relayed to muscles and glands
3. What is the CNS the site of?: -Emotion
-Memory
-Cognition
-Learning
4. What protects the CNS?: -Cerebrospinal fluid ( CSF)
-Skull and vertebrae
-Blood-brain barrier
-Meninges
5. Describe the meninges in the CNS: -Dura mater
-Arachnoid mater
-Pia mater
6. What are the 4 lobes of the brain?: -Frontal
-Temporal
-Occipital -
Parietal
7. What does the frontal lobe control?: reasoning, planning, parts of speech,
movement, emotions, and problem solving
8. What does the temporal lobe control?: hearing and balance, interpretation
of sensory experiences, memory of visual scenery and music
,9. What does the parietal lobe control?: interprets sensory perception, parts of
speech, taste, and reading
10. What does the occipital lobe control?: processing visual information
11. What does the sympathetic nervous system (SNS) do?: -speeds up
-fight or flight
12. What does the parasympathetic nervous system (PNS) do?: -slows down
13. Ischemic stroke from arteriosclerosis?: -thrombi in areas of plaque -plaque
dislodges
14. Ischemic stroke from atrial fibrillation?: -left atrium, quivering -stasis of
blood
-clot
15. Ischemic stroke from carotid stenosis?: -lumen narrows -blood flow
obstruction
16. What happens in an ischemic stroke?: -artery is occluded cause decreased
perfusion
-brain swells and an increase in pressure causes a decreased LOC -
cushing's triad: altered respirations, bradycardia, and hypertension.
17. What does F.A.S.T. stand for in relation to a stroke?: -Face... does it look
uneven?
-Arm... is one arm hanging down?
-Speech... is their speech slurred?
-Time... call 911 now!
18. What is a hemorrhagic stroke?: a stroke caused by bleeding into the brain
from trauma or ruptured blood vessel
19. What are the two types of seizures?: -focal
-gereralized
20. What happens in a focal seizure?: -activity is restricted to one brain
hemisphere
-simple: no LOC, symptoms based on part of brain involved
-complex: possible LOC, can progress
21. What happens in a generalized seizure?: -Entire brain is involved from the
onset of the seizure.
22. What is an absence (petit mal) seizure?: -lasts less than a minute
-staring "spells" unaware of environment
,-usually motionless but not uncommon for the person to continue walking or
performing a routine tasks
-almost always in children and the onset and termination is abrupt
23. What is a clonic seizure?: -consist of contraction to flexion, jerking
movements
-falls
-no LOC
24. What is a tonic seizure?: -stiffness in muscles for 20-30 seconds
-falls
-no LOC
25. What is an atonic seizure?: -sudden and complete loss of muscle tone for 15
seconds
-falls
-no LOC
26. What is a tonic-clonic ( grand Mal) seizure?: -sudden LOC -muscle rigidity
-could last 5 min/ longer
-falls
-tongue biting
-apnea until end of clonic phase
27. What is the role of the nurse when a patient is experiencing a seizure?: -
place on side
-do not restrain
-don't put anything in their mouth
-keep pt free form injury
28. What is the etiology of Parkinson's Disease?: -idiopathic (most common
85-90%)
-genetic link (10%) -
aquired:
-infection
-intoxication
-trauma
-drug toxicity ( high caffeine intake has an inverse relationship to development!)
29. What is the pathogenesis of Parkinson's Disease?: -progressive loss of
dopamine producing cells in the substantial nigra
-Lewy bodies are found in surfing neurons causing abnormal proteins
, -ANS may be involved
30. What are the signs and symptoms of Parkinson's?: -first sx is a resting
tremor
-"pill rolling"
-impaired walking, dressing, writing, and eating
31. What is Amyotrophic Lateral Sclerosis(ALS) Lou Gehrig's Disease?: -
progressive degenerative disease affecting both the upper and lower motor
neurons
-muscle wasting and atrophy
-more men than women (40-60)
-smoking is the biggest risk factor
32. What is the pathophysiology of ALS?: -rapid production
-neurodegenerative
-destruction of motor neurons
-sensory and cognitive neurons are still intact
33. What are treatments for ALS?: -no cure
-manage symptoms and quality of life -swallowing
problems can lead to aspirations dysfunction of
diaphragm can lead to respiratory failure.
-riluzole (rilutek) decreases glutamate to reduce damage to motor neurons.
34. What is the etiology for Multiple Sclerosis (MS)?: -chronic demyelinating
disease of the CNS in young adults
