A client has had continuous generalized tonic-clonic seizure activity for 6 minutes. Intravenous access is patent, and oxygen and suction equipment are available. Which prescribed medication should the nurse administer first?
1Administer the prescribed intravenous levetiracetam loading dose
2Administer the prescribed intravenous lorazepam dose now✓ Correct answer
3Administer the prescribed intravenous fosphenytoin loading dose
4Give the prescribed oral carbamazepine maintenance dose
Explanation
Convulsive seizure activity lasting at least 5 minutes requires status epilepticus treatment. With intravenous access, an intravenous benzodiazepine such as lorazepam is effective initial therapy before longer-acting antiseizure loading medication.
Quick answer Give the prescribed intravenous lorazepam now. Ongoing convulsive activity beyond 5 minutes is treated as status epilepticus, and a benzodiazepine is the first medication step.
Why this is correct Prolonged seizure activity becomes harder to stop and increases metabolic, respiratory, and neurologic injury. Lorazepam enhances inhibitory signaling quickly, making it appropriate initial therapy when intravenous access is already available.
Easy analogy or mental picture Lorazepam acts like an emergency brake that slows the seizure before a longer-lasting parking brake is applied. The analogy explains sequence, but airway support, dosing, monitoring, and the cause of the seizure still require active management.
Memory hook Convulsions at 5 minutes: benzodiazepine first, then longer-acting seizure control.
NCLEX decision rule For active convulsive status epilepticus with intravenous access, choose the prescribed intravenous benzodiazepine first while supporting airway and breathing. Loading medications such as levetiracetam or fosphenytoin generally follow if needed for sustained control.
Why the other choices are wrong Levetiracetam and fosphenytoin may be used as second-phase loading therapy but do not replace the initial benzodiazepine. Oral carbamazepine is too slow and unsafe to administer during active convulsions.
