Seizures
A patient stares blankly for 10 seconds then resumes conversation — that was a seizure.

Seizures
Abnormal electrical bursts in the brain. Side-lying, nothing in the mouth, never restrain — time it.
The brain seen from above, two hemispheres. In a focal seizure the electrical storm starts in one hemisphere and stays there, and awareness may stay. In a generalized seizure both hemispheres light up at once, and consciousness is lost.

The 5-minute line
Status epilepticusA seizure clock starts at zero as the EEG breaks into seizure activity. Sped up, the clock counts the minutes: 1, 2, 3, 4. At 5 minutes the ring turns rose: status epilepticus.

Act nowDuring the seizure
First aidKeep them safe and the airway open — you time the seizure, you never stop it by force
No tongue blade, oral airway or fingers — teeth break and pieces can be aspirated.
Never hold down the limbs; forcing the movement can injure the patient or you.
Oxygen by cannula or mask as needed — now if cyanosis appears. Suction the mouth once the convulsions stop.
Status epilepticus: IV lorazepam first (or IM midazolam, IV diazepam). Still seizing → a second IV drug: fosphenytoin, levetiracetam or valproic acid.

Before dischargeTurn them to the side, time it, never hold them down. Nothing goes in the mouth — and 5 minutes makes it status epilepticus.

Seizures
A patient stares blankly for 10 seconds then resumes conversation — that was a seizure. If you can't classify it, you can't protect or document it accurately.
Seizures divide into two major categories based on where abnormal electrical activity begins. Generalized seizures involve both hemispheres from onset and always produce loss of consciousness. The most dramatic is the tonic-clonic (grand mal): a tonic phase of rigid muscle contraction (10-20 seconds) followed by a clonic phase of rhythmic jerking (30-60 seconds), often with incontinence and a postictal period of confusion lasting minutes to hours. Absence (petit mal) seizures are brief (5-30 seconds), present as staring spells with possible eyelid fluttering, have no postictal phase, and are most common in children. Focal (partial) seizures originate in one hemisphere. Simple focal seizures preserve consciousness — the patient may report an aura (unusual taste, smell, déjà vu). Complex focal seizures impair awareness and produce automatisms (lip smacking, picking at clothes). Nursing priorities during any seizure: stay with the patient, do not restrain or insert anything into the mouth, turn to the side when possible, note the time, and document onset body part, progression, duration, and postictal behavior. Pad side rails for known seizure disorder patients and maintain suction at the bedside.
Key Distinctions
Don't confuse absence seizures (brief staring, no postictal phase) with complex focal seizures (automatisms, postictal confusion present). Students often think tonic-clonic is the only generalized type — absence, myoclonic (brief involuntary muscle jerks), and atonic (sudden loss of muscle tone causing 'drop attacks') are also generalized. Never document 'the patient had a seizure' — specify the type, body parts involved, duration, and level of consciousness throughout.
Clinical Pearl
Time it, don't fight it. Your job during a seizure is to protect, observe, and document — not to stop the movement or pry open the jaw.
Seizure Precautions
Seizure precautions are a bundle of environmental and nursing actions implemented for any patient at risk for seizures (epilepsy, eclampsia, alcohol withdrawal, post-craniotomy, electrolyte imbalances). The environment is set up proactively: bed in lowest position, padded side rails up, suction equipment at bedside and tested, oxygen and oral airway within reach, IV access maintained. During an active seizure, your priorities follow a strict hierarchy: protect the airway, protect from injury, observe and document. Turn the patient to the side to maintain airway patency and prevent aspiration. Never force anything into the mouth — no tongue blade, no oral airway, no fingers. The patient cannot swallow their tongue; attempting to insert objects risks broken teeth, soft tissue injury, and aspiration of fragments. Time the seizure from onset. If it lasts longer than 5 minutes or seizures recur without recovery of consciousness between episodes, this is status epilepticus — a medical emergency requiring immediate intervention (typically IV benzodiazepines per protocol). After the seizure, the postictal phase includes confusion, drowsiness, and possible incontinence. Maintain a safe, quiet environment, perform a neurological assessment, and document seizure type, duration, body parts involved, preceding aura, and postictal behavior.
Key Distinctions
Don't confuse seizure precautions (proactive environmental setup) with seizure management (actions during the event) — NCLEX tests both separately. Students think you should restrain the patient during a seizure; you never restrain — you guide, not hold. Padded tongue blades are outdated and dangerous; nothing goes into the mouth during a seizure, despite what older references state.
Clinical Pearl
During a seizure: time it, turn them, stay with them. Nothing in the mouth — ever. If it hits 5 minutes, think status epilepticus.
