On Final Test Flashcards
How does CNS and PNS relate to treatment of epilepsy ?
Central nervous system disease treated in the periphery
What is epilepsy a disease of?
Epilepsy is a disease of central nervous system
What type of affects do seizures produce?
Seizures may produce both autonomic and somatic affects
What number cranial nerve does VNS stimulate
10 wandering nerve
What types of fibers does vagus nerve mainly consist of and how much of that type?
80% Afferent
Where does VNS stimulate on nerve - between what and what?
Above laryngeal
Below cardiac branches
What are neurons made of?
Cell body
Dendrites
Axon
Synapse
Goal of VNS with regard to nerve fibers?
Stimulate and saturate myelinated A fibers
Are most synapses in body chemical or electrical?
Majority chemical
Very few electrical
What makes partial seizures important ?
Partial seizures usually begin with symptoms that reflect site of origin
Seizures can be what 2 main varieties?
Partial and Generalized
What is the purpose of dosing?
Maximize therapeutic effect
Minimize side effects
With 103 and 104 generators systems diagnostic and normal mode diagnostic run simultaneously. TRUE or FALSE
TRUE
Case study question:
The output is okay & the delivery is that 1.0 milliamp. The impedance value is 4138 ohms. So basically nothing is wrong. What do you do?
Interrogate and you’re done
There is a potential of a lead fracture in this question. With multiple choice all over the place that all work so it is all of the above
All of the above
How do you know you have a short circuit?
Low impedance less than 600
Purpose of strain relief loop and bend
To allow greater mobility of the head and neck
For longer durability of the lead
And to take off additional tensioning on the lead
Case study:
The output current is low and the 2.5 impedance is high - how do you troubleshoot?
Check the pin
Make sure nerve hasn’t dried out
Check lead
What must you remember with the compatibility matrix between generators and leads
Everything is compatible except the 300 lead only goes with the 102 are and the 104 generators
Select the correct answer about what is true about focal point seizures
Start in one place of brain
On time is defined as the amount of time including ramp up and ramp down
False
What is not in the patient essentials kit
Does not contain a magnet brochure
There is a question about what the following can be said about the EMU
It’s all of the above
It includes things like
several reasons
measures electrical activity in the brain
Medication with a novel mechanism of action
Fycompa
There will be a question that has a list of medications and which one is for refractory epilepsy
Vimpat
What are the different partial/focal seizure types?
Simple partial
complex partial
focal on set with secondary generalized
What are the five types of generalized seizures?
Tonic clonic absence atonic myoclonic
What does RNS stand for?
Responsive nerve stimulation
What does glutamate and GABA do in relation to seizures
Glutamate excites and GABA brings it back to normal
Action potential starts at what part of the lead
Negative electrode
