📚 Febrile Seizures — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Febrile seizures are generalized convulsions triggered by a rapid rise in body temperature, usually with a fever above 38C (100.4F), in children typically 6 months to 5 years old. They are usually benign and self-limiting and do not cause brain damage or epilepsy in most children. They are most often associated with a viral illness; the rate of temperature change matters more than the absolute peak.
🔑
Key points
Understand these first
A simple febrile seizure is generalized, lasts under 15 minutes, and does not recur within 24 hours.
A complex febrile seizure is focal, lasts longer than 15 minutes, or recurs within 24 hours.
They occur most commonly during the rapid temperature spike, often early in the illness.
Most children outgrow them by age 5 and have a normal neurologic outcome.
A family history of febrile seizures increases the likelihood.
The postictal child may be briefly drowsy or confused after the seizure.
✅
Nursing priorities
What to do, in order
During the seizure, protect the airway: position the child on their side and do not restrain or put anything in the mouth.
Stay with the child, time the seizure, and clear the area of hazards.
Administer antipyretics (acetaminophen or ibuprofen) as ordered to reduce fever.
Treat the underlying cause of the fever and keep the child cool with light clothing.
Monitor and document seizure duration, characteristics, and postictal state.
🚩
Red flags — report now
Escalate immediately
A seizure lasting longer than 5 minutes or repeated seizures (status epilepticus) is a medical emergency.
Never restrain the child or place objects or fingers in the mouth during a seizure.
Signs of meningitis (nuchal rigidity, bulging fontanelle, petechial rash, severe lethargy) require immediate evaluation.
Focal, prolonged, or recurrent seizures need prompt provider notification and workup.

Patient teaching
What patients must know
These seizures are usually harmless and do not mean the child has epilepsy.
Give antipyretics as directed and dress the child lightly when feverish.
During a seizure, lay the child on their side, protect them from injury, time it, and never put anything in the mouth.
Call emergency services if a seizure lasts more than 5 minutes or the child has trouble breathing afterward.
