Q

what is the patho of migraines

A

“pathological cause”

  • vascular, genetic, chemical, trigemal vascular system (spasms, decreased blood flow), hypoxia, artery dilation (prostaglandin trigger)

Q

describe bacterial meningitis

A

organisms enter CNS through BBB

results in inflammatory response

22
Q

what are the risk factors of bacterial meningitis

A

bacterial infection (ie/ resp infection), immunosuppression, invasive procedure, head injury, overcrowded living conditions (college dorms)

23
Q

how is bacterial meningitis diagnosed

A

cerebrospinal fluid analysis: obtained via lumbar puncture

*broad spectrum antibiotic given BEFORE puncture

24
Q

nursing care of meningitis

A
  • monitor ABC
  • neuro and VS check every 2-4 hrs
  • motor changes and I & Os
  • antibiotics (Rocephin and antiepileptics)
  • decreased environmental stimuli
  • isolation precautions (standard unless airborne bacteria identified)
25
what complications of meningitis do you want to prevent
- increased ICP (brain swelling would cause pupil changes) - vascular dysfunction - seizures, shock - fluid and electrolyte imbalance
26
difference between Ach and dopamine
Ach: excitatory neurotransmitter dopamine: inhibitory neurotransmitter
27
what are the four signs of Parkinson's
1) rigidity 2) slow movement (akinesia) 3) tremor at rest 4) impaired postural reflexes, fall forward
28
what is akinesia
slow movement
29
patho of Parkinson's
- neurotransmitter disease - balance of dopamine and Ach is disrupted - degeneration of dopamine(decreased) producing neuron - decreased norepinephrine also causes orthostatic changes
30
when do symptoms appear in Parkinson's
when 80% of basal ganglia are gone
31
what are the risk factors of parkinson's
increased with age more common in men genetics or brain injury may cause this
32
what are the stages of Parkinson's
1) symptoms on one side of body, tremors 2) bilateral limb movement, slow gait 3) shuffling, propulsive gait with flexed arms 4) akinesia, rigidity 5) complete dependence (may never reach this stage)
33
Cogwheel
rhythmic movement
34
dysarthia
slurred speech
35
features of Parkinson's
- stooped posture - shuffling, propulsive gait - bradykinesia and cogwheel - dysarthia, echolalia, hypophobia - liable, mood swings
36
what are the signs of Parkinson's
- cannot relax arms or face (masklike) - orthostatic hypotension (fall risk) - tremors at rest, lack inhibitory neurotransmitter (dopamine)
37
diagnostic test of Parkinson's
no specific test diagnosis when 2 or 3 characteristics are present triad (tremor, rigidity, bradykinesia)
38
when is Parkinson's confirmed
positive response to antiparkinonian drugs
39
what is drug therapy for Parkinson's
- correct imbalance of neurotransmitters - enhance or release supply of dopamine - goal is to decrease symptoms
40
drug that is a precursor to dopamine | given for Parkinson's
Levodopa cross BBB and turns into dopamine in basal ganglia cannot give straight dopamine because it will NOT cross BBB
41
what is given with Levodopa for Parkinson's
Carbidopa | inhibits enzyme that breaks down levodopa before it reaches the brain
42
why is Requip given to Parkinson's pt
dopamine agonist stimulates production of dopamine BUT can cause hypotension and hallucinations
43
why is Cogentin give to Parkinson's pt
anticholinergic | decreases Ach, controls tremors, rigidity and sweating
44
what do anticholinergics do (broadly)
dry the pt out
45
other therapies for Parkinson's
exercise and ambulation injury prevention, counseling OT and ADL and ST therapy nutrition, soft food, thicken foods
46
inability to use words or objects correctly
apraxia
47
inability to find words
anomia
48
inability to speak or understand
aphasia
49
loss of sensory comprehension
agnosia
50
agnosia, aphasia, anomia, and apraxia are found in what disease
Alzheimer's
