Seizure Disorders

NCLEX Review Guide: Pediatric Seizure Disorders

Overview of Pediatric Seizure Disorders

Types and Classifications

  • Generalized seizures involve both hemispheres of the brain and include tonic-clonic, absence, myoclonic, and atonic types. These seizures typically cause loss of consciousness and bilateral motor involvement.
  • Focal seizures originate in one area of the brain and may be simple (consciousness preserved) or complex (consciousness impaired). They can progress to generalized seizures.
  • Febrile seizures occur in children 6 months to 5 years old with fever >100.4°F (38°C). Simple febrile seizures last <15 minutes, are generalized, and don't recur within 24 hours.

Seizure Type Comparison

TypeCharacteristicsDurationConsciousness
Tonic-ClonicStiffening then jerking1-3 minutesLost
AbsenceStaring, lip smacking5-30 secondsImpaired
MyoclonicBrief muscle jerksSecondsUsually preserved

Key Points

  • Status epilepticus is a seizure lasting >5 minutes or recurrent seizures without full recovery - this is a medical emergency
  • Most pediatric seizures are brief and self-limiting
  • Febrile seizures are the most common type in children

Nursing Assessment and Interventions

During Seizure Management

  1. Stay with the child and remain calm - never leave a seizing child unattended
  2. Position child on side to prevent aspiration and maintain airway patency
  3. Remove harmful objects from environment but never restrain the child or place objects in mouth
  4. Loosen tight clothing around neck and waist
  5. Time the seizure duration and observe seizure characteristics
  6. Administer oxygen if available and monitor vital signs

Clinical Scenario

A 4-year-old child begins having a tonic-clonic seizure in the hospital playroom. The seizure has lasted 3 minutes. Priority nursing actions include positioning the child on their side, timing the seizure, removing nearby toys, and preparing for possible medication administration if seizure continues beyond 5 minutes.

Memory Aid - Seizure Management

SAFE:
Stay with child
Airway - position on side
Free from harm - clear environment
Evaluate and document

Key Points

  • Document seizure onset, duration, body parts involved, and postictal behavior
  • Postictal period may include confusion, sleepiness, and temporary weakness

Medications and Treatment

Antiepileptic Drugs (AEDs)

  • Phenytoin (Dilantin) requires monitoring of drug levels, gingival hyperplasia, and IV administration must be slow to prevent cardiac arrhythmias. Therapeutic level is 10-20 mcg/mL.
  • Carbamazepine (Tegretol) can cause bone marrow suppression requiring regular CBC monitoring. It's effective for focal seizures and has fewer cognitive side effects.
  • Valproic acid (Depakote) is broad-spectrum but can cause hepatotoxicity, thrombocytopenia, and weight gain. Monitor liver function tests regularly.
  • Emergency medications include IV lorazepam, diazepam, or midazolam for status epilepticus

Key Points

  • Never abruptly discontinue AEDs - can precipitate status epilepticus
  • Medication compliance is crucial for seizure control
  • Many AEDs interact with other medications and affect drug metabolism

Commonly Confused Concepts

Febrile vs. Epileptic Seizures

FeatureFebrile SeizureEpileptic Seizure
Age6 months - 5 yearsAny age
TriggerFever >100.4°FVarious or none
RecurrenceOnly with feverUnpredictable
TreatmentFever controlAntiepileptic drugs

Key Points

  • Simple febrile seizures don't require AED treatment
  • Complex febrile seizures may require further evaluation

Family Education and Discharge Planning

Teaching Points

  • Teach family seizure first aid: stay calm, position on side, time seizure, call 911 if >5 minutes
  • Emphasize medication compliance and regular follow-up appointments for drug level monitoring
  • Discuss seizure triggers such as sleep deprivation, stress, flashing lights, and missed medications
  • Address safety concerns including swimming supervision, bicycle helmets, and avoiding heights

When to Call 911

Call emergency services if:
• Seizure lasts >5 minutes
• Difficulty breathing after seizure
• Injury during seizure
• First-time seizure
• Seizures occur in clusters

Key Points

  • Most children with epilepsy can participate in normal activities with precautions
  • School personnel should be educated about the child's condition and emergency plan

Quick Check Self-Assessment

  • ☐ I can identify different types of pediatric seizures
  • ☐ I know the priority nursing interventions during a seizure
  • ☐ I understand when seizures become medical emergencies
  • ☐ I can differentiate between febrile and epileptic seizures
  • ☐ I know key teaching points for families

Common NCLEX Pitfalls

  • Never restrain a seizing child or place objects in their mouth
  • Status epilepticus is >5 minutes, not >30 minutes
  • Simple febrile seizures don't require AED treatment
  • Always position child on side, never supine during seizure

Remember: You're preparing to be an excellent pediatric nurse! Master these seizure management skills - they could save a child's life. Stay confident and keep studying! 🌟
