## Question

An adult patient has been seizing continuously for 6 minutes. The provider asks the nurse to anticipate the first-line pharmacologic intervention. Which medication should the nurse have ready?

## Option

1. IV phenytoin 20 mg/kg loading dose now.
2. IV lorazepam 4 mg over 2 minutes; may repeat once after 5 to 10 minutes if seizing continues. **✔ Correct answer**
3. IV mannitol 1 g/kg to reduce intracranial pressure.
4. Subcutaneous epinephrine 0.3 mg.

**Correct answer: 2**

## Explanation

Status epilepticus = continuous seizure ≥ 5 minutes (or recurrent without return to baseline). The first-line agent is an IV benzodiazepine — lorazepam 4 mg IV (or midazolam 10 mg IM if no IV access). Phenytoin/fosphenytoin is the SECOND-line agent if seizures persist. Mannitol and epinephrine are not used for status. Airway, oxygen, side positioning, and IV access run in parallel.

## In-depth explanation

Memorize the staircase: benzo → fosphenytoin/levetiracetam/valproate → propofol or midazolam infusion (refractory). Lorazepam 4 mg IV is the most-tested first-line answer. Time matters: each minute of seizing increases morbidity and refractoriness.

## Clinical scenario

**Adult patient with continuous tonic-clonic seizure activity for 6 minutes** — meets criteria for **status epilepticus**. Airway is being managed with side positioning and suction. IV access is established.

## Key concepts

- **Status epilepticus** — Continuous seizure ≥ 5 minutes or recurrent seizures without return to baseline; medical emergency.
- **IV lorazepam** — First-line benzodiazepine; 4 mg IV over 2 minutes, may repeat once.
- **Fosphenytoin (second-line)** — Loading 20 mg PE/kg IV after benzodiazepines fail; less hypotension than IV phenytoin.
