-seizure type.
-characteristics.
-medical hx.
-results of EEG and other diagnostic tests.
-comorbid conditions.
What should patients be educated on in regards to there antiepileptic medication regimen
Never stop taking medication even if “better” without guidance of HCP.
(may cause withdrawal seizures)
What parts of the CNS do benzodiazepines work in order to control seizures
Limbic, thalamic, hypothalamic
Benzodiazepines have a).. and are used for seizures when other drugs are provens ineffective
a).. limited applications
When administering benzodiazepines via IV route, what should the nurse ensure
Resuscitation equipment should be readily available. And the nurse should monitor pt closely for CV collapse and respiratory depression.
What considerations should the nurse take when administering or caring for a patient who is taking benzodiazepines
-educate on S+S of resp depression.
-assess for decrease in seizure activity.
-maintain pt safety pre+post seizure (triggers).
-assess for smoking hx (may need bigger dose).
-assess for urinary retention
-do not mix with other drugs parenterally.
what is the family last name of benzodiazepines
“azepam”, clorazepate (tranxene) is a exception to the rule.
Patient has been seizure and wants to know why they still need blood tests, What would be the best reason?

-watch for extravasation with IV route/
-Check blood levels regularly (lithium/dig)

-lupus
-cardiac/hepatic disease.
-HTN
-older adults

Valproic acid drug interactions
CNS depressants, alcohol
= additive sedation.
Enzyme-inducing AEDS
=more rapid metabolism.
TCA: increased serum levels.
aspirin, isoniazid, cimetidine= increased serum levels (bleeding risk ).
decreased absorption of cholestyramine
What is the tmt for overdose for valproic acid
-Naloxone (narcan)
may also reverse antiseizure action of valproic acid.
-Hemodialysis
