NUR2020 Exam 2: Seizures, Kidney Disease,
& Liver Disease Exam Questions With
Correct Answers
What are seizures? - answer✔electrical disturbances (arrthymias) in the nerve cells in one
section of the brain
What causes seizures (primary vs. secondary causes) - answer✔- Primary: 75% of seizures are
idiopathic - causes is unknown
- Secondary: the rest are caused by structural, febrile, or metabolic reasons
Examples of secondary: cortical dysplasia, double cortex, low electrolytes (any), maternal drug
use, stroke, meningitis (ESP. BACTERIAL), TORCH infections, genetic disorders, etc.
What are generalized onset vs. partial/focal onset seizures? - answer✔- Generalized affect
BOTH sides of the brain: includes motor (tonic clonic) and nonmotor (absence) seizures
- Partial/focal: start in one area on one side of the brain: includes focal aware and focal impaired
awareness seizures
What are some triggers for seizures? - answer✔flashing lights, missed medications, temperature
extremes, sounds, illness, stress, anxiety, overstimulation/sensory overload, lack of sleep, alcohol
abuse/withdrawal
What data should be assessed with a seizure patient? - answer✔How often do seizures occur?
Are there any warning signs?
What are the symptoms present during the seizure?
How long are your seizures?
phenytoin (Dilantin) - answer✔- Used for tonic-clonic & partial seizures
- S&S: gingival hyperplasia, hystagmus, hirsutism (male pattern hair on women), ataxia, folate
deficiency, drug induced lupus, myelosuppresion
- Signs of toxicity: ataxia, rash that could indicate Steven-Johnson syndrome

- Nursing considerations: do not give with milk or antacids, monitor serum levels closely (should
be 10-20 mcg); will prolong the half-life of warfarin & coumadin (PT/INR will get longer -
patient more likely to bleed b/c even slower clotting); may worsen MG symptoms; will
deactivate oral contraceptives- use alternative birth control methods
carbamezepine (Tegretol) - answer✔- Used for secondary tonic-clonic & partial seizures
- S&S: ataxia, diplopia, hepatitis, aplastic anemia, behavior changes
- Nursing considerations: monitor for visual changes, monitor liver function (AST/ALT),
monitor CBC, do not crush or chew
All the drugs ending in -pam
(Lorazepam, Diazepam, Clonazepam) - answer✔- anti-seizure meds (anxiolytics, benzos)
- S&S: sedation, amnesia, hallucinations, insomnia, visual disturbances, respiratory depression,
lack of appetite or appetite changes
- Nursing considerations: ANTIDOTE: Flumazenil, monitor renal & liver function and labs if
using long-term, do not discontinue rapidly, can exacerbate MG symptoms, patients can develop
tolerance if used often and it will not be as successful
What diet can help with epilepsy? - answer✔Keto (high fat, low carb) - still need to use
medications
Vagus nerve stimulator therapy (VNS) - answer✔Sends electrical impulses to the vagus nerve
which carries pulses to the brain (runs up the side of the neck)
- This helps prevent or shorten length of seizures
What are seizure precautions? - answer✔Oxygen
Suction equipment
Bed close to ground
IV access ready
Side rails up and padded w/one pillow or pad each
Teaching plan fro patient & family w/epilepsy - answer✔- It's not contagious, not a mental
illness, or cognitive disability
- Can start at any point in life
- Adhere to your medication regimen

- Citrus, especially grapefruit can interfere with the metabolism of many seizure meds
- Period blood work is needed - monitor albumin and electrolyte levels
- Know your state's law for driving after seizures: MD is 90 days seizure free, DC/VA are 12
months
How is epilepsy diagnosed? - answer✔1. Medical History
2. Tests: lab studies, serum electrolytes, lumbar puncture and brain studies (CT, MRI, PET scan)
to look for abnormalities and rule out other diseases
3. **Electroencephalography (EEG) to look at electrical activity of the brain
3. Clinical Observation: motor function, sensory function, neuropsychological eval
Notes: accurate description and video recordings help diagnose & classify types of seizures
What is an Electroencephalogram (EEG)? - answer✔An amplified recording of brain activity is
measured by electrodes placed on the scalp - the technician will ask you to picture certain things,
look at images, etc.) and the EEG will evaluate how you respond to stimuli
- Considerations: DO NOT TAKE SEIZURE MEDS before an EEG, avoid caffeine and other
stimulants before, sleep deprivation is good, patient CAN eat
What are the stages of a seizure? - answer✔- Prodromal: warning signs before a seizure
- Aura/preictal phase: Visual, auditory clues that happens seconds-minutes before a seizure (such
as smelling things that are not there)
- Ictal phase: SEIZURE phase (Tonic stage: incontinence, stiff, cry & clonic stage: jerky, frothy
saliva, blinking)
- Postictal: hangover phase from the seizure - may be confused, tired, have a headache
What is status epilepticus? - answer✔May be life threatening!
Seizure more then 5 minutes long, repetitive without periods of consciousness
