Seizure types

Classification affects observation and teaching.

Seizure types. A focal seizure can spread to both sides (focal to bilateral tonic-clonic).

During and after a seizure

Safety and observation are the nurse's main jobs.

During a seizure. Do not restrain or insert anything in the mouth; turning to the side helps secretions drain.
After the seizureRationale
Assess airway, breathing, oxygen saturation; suction if neededSecretions and depressed consciousness
Keep side-lying; reorient gentlyPostictal confusion and drowsiness are expected
Check for injury (tongue, head, limbs)Falls and convulsive movements
Document onset, duration, movements, eyes, incontinence, and recoveryHelps classify the seizure

Seizure precautions per policy: bed low, side rails padded if used, suction and oxygen at the bedside.

Status epilepticus

Prolonged seizures can cause brain injury and must be stopped quickly.

TimeTreatment (as ordered)
0–5 minAirway, oxygen, glucose check, IV access, monitor
5 min or moreBenzodiazepine: IV lorazepam, IM midazolam, or rectal diazepam
If seizures continueSecond-line IV drug: fosphenytoin, levetiracetam, or valproate
RefractoryAnesthetic agents with intubation in intensive care

Check glucose early; hypoglycemia is a treatable cause of seizures.

Antiseizure medications and teaching

Monitoring and teaching prevent toxicity and breakthrough seizures.

PhenytoinLevel about 10–20 mcg/mLIV: saline only; slow; cardiac monitorGingival hyperplasia: good oral careToxicity: nystagmus, ataxia, slurredspeechMany drug interactionsAll antiseizure drugsTake daily; never stop abruptlyReport rash (serious reactions)Medical IDDriving rules vary by stateDiscuss pregnancy plans (valproate isteratogenic)vs
Antiseizure medications. Levetiracetam can cause mood changes; carbamazepine can cause low sodium and blood dyscrasias.
  • Febrile seizures: common between about 6 months and 5 years; most last under 15 minutes and resolve without lasting harm. Teach parents seizure first aid and when to call emergency services.
  • Avoid triggers where known: sleep deprivation, alcohol, missed doses, flashing lights in photosensitive epilepsy.

NGN-style case

Timing decides the action.

functions Clinical judgment case — the seizure that will not stop

A client's generalized tonic-clonic seizure has lasted 6 minutes. SpO₂ is 88%. There is IV access. What should the nurse anticipate first?

  1. Recognize cues: seizure longer than 5 minutes; hypoxemia.
  2. Analyze: status epilepticus.
  3. Support airway with oxygen and side-lying position; call the rapid response team.
  4. Give IV lorazepam as ordered; prepare a second-line drug if seizures continue; check glucose.

Answer. Treat as status epilepticus: oxygen and airway support, call for help, and give an IV benzodiazepine as ordered.
