Seizures (Final exam) Flashcards
What is a seizure?
transient, uncontrolled electrical discharge of neurons in the brain that interrupt normal function
What is a tonic-clonic seizure (grand mal)? (4)
- most common generalized-onset motor seizure
- patient loses consciousness and falls to the ground if standing up
- body stiffens (tonic) for 10-20 seconds and extremities jerk (clonic) for another 30-40 seconds
- manifestations that can occur during the seizure: cyanosis, excessive salivation, tongue/cheek biting, incontinence
4 phases of seizure
1) prodromal: sensations or behavior that precede a seizure by hours or days (ie: anxiety or not feeling well)
2) aural: sensory warning that is similar each time a seizure occurs, considered part of seizure (ie: patient knows that seizure is about to happen)
3) ictal: first symptoms to the end of the seizure
4) post-ictal: recovery period after the seizure
Assessment findings for the post-ictal phase of a seizure (3)
- muscle soreness, feels tired, may sleep for several hours
- some patients feel normal for several hours or days after a seizure
- no memory of the episode
What diagnostic finding should a new-onset patient have?
Normal CT and EEG findings are common in seizure disorder, especially the first time that testing occurs
Possible underlying triggers that a first-time patient may have? (6)
- excess alcohol intake
- fatigue
- loss of sleep
- trauma
- disease
- high fever
Complications of seizures (2)
1) status epilepticus
2) psychosocial effects
Status epilepticus (4)
state of continuous seizure activity that recur in rapid succession without return to consciousness between the seizures
neurologic emergency
any seizure lasting longer than 5 mins (monitor length of seizure)
treatment: IV lorazepam/Ativan or diazepam/Valium (then long-acting anticonvulsant like phenytoin) neurologic assessment involves testing for toxicity
Psychosocial effects of seizure disorder (4)
- depression
- social stigma
- discrimination in employment and education opportunities
- driving sanctions
What tasks can be delegated to a UAP in seizure management? (5)
- apply intermittent pneumatic compression devices
- assist with repositioning
- vitals, seizure precautions
- daily hygiene and bathing
- emotional support/encouragement
Emergency seizure precautions
1) place on flat ground, support head, turn to side to prevent aspiration
2) ensure safety during seizure
3) record location, duration, details of the event
4) assess vitals and gag reflex, if none then intubate and maintain patent airway
patient teaching for EEG (4)
- painless
- can wash hair
- avoid caffeine 6-8 hrs before
- hold medications and give after
Why do patients who had a seizure get their glucose level checked?
can be hypoglycemic = IV dextrose if hypoglycemic
For patients who seizures cannot be controlled with drug therapy, which intervention is needed?
surgery to resect the focal area (patient must be awake)
Nutritional needs for patients after a seizure
high fat, low carb = ketogenic diet
