A client was admitted to the neurological unit yesterday with new onset seizures. The seizures have been lasting for just over four minutes, and the nurse is concerned that they may start to last longer. Which prescription should the nurse ensure is written by the health care provider and always on hand for this client?

Management of a client with new-onset seizures requires rapid intervention planning to prevent progression to status epilepticus, a neurological emergency characterized by prolonged or recurrent seizures without recovery of consciousness. Acute seizure control relies on fast-acting anticonvulsant medications that can be administered intravenously to quickly terminate seizure activity. Ensuring the availability of emergency medications is a critical nursing safety priority in neurological care settings. Rationale: A. Oral phenytoin is used for long-term seizure control and maintenance therapy but is not appropriate for acute seizure termination. It has a delayed onset of action and cannot rapidly stop ongoing seizure activity. Therefore, it is not suitable for emergency management or as an immediate rescue medication. B. Intravenous lorazepam is the first-line emergency medication for acute seizure control and prevention of status epilepticus. It is a fast-acting benzodiazepine that enhances GABA activity, leading to rapid CNS depression and seizure cessation. Because of its quick onset and effectiveness, it should be readily available at the bedside for immediate administration during prolonged seizures. C. Intravenous phenobarbital may be used for refractory seizures but is not typically the first-line emergency medication. It has a slower onset compared to benzodiazepines and carries a higher risk of respiratory depression and sedation. It is generally reserved for seizures that do not respond to initial benzodiazepine therapy. D. Oral carbamazepine is a maintenance anticonvulsant used for chronic seizure disorders but is not effective for acute seizure management. Its oral formulation and delayed therapeutic onset make it unsuitable for emergency situations. It is prescribed for long-term stabilization rather than immediate seizure termination.
