The nurse is preparing to administer amantadine 150 mg PO every 12 hours. The available medication is amantadine 50 mg/5 mL syrup. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A reason: Stopping AEDs when seizures stop is incorrect, as it risks rebound seizures due to unopposed neuronal excitability. Most patients require long-term therapy to maintain seizure control, especially in chronic epilepsy, guided by neurological evaluation.
Choice B reason: AED therapy is often lifelong for chronic epilepsy, as seizures result from persistent neuronal hyperexcitability. Maintaining therapeutic drug levels prevents recurrence, as the underlying neurological predisposition remains, requiring continuous management to stabilize brain activity.
Choice C reason: Consistent dosing maintains steady-state AED levels, preventing subtherapeutic concentrations that could trigger seizures. Fluctuations in drug levels disrupt neuronal stabilization, increasing seizure risk, making adherence to dosing schedules critical for effective epilepsy control.
Choice D reason: Skipping doses due to adverse effects is dangerous, as it lowers AED levels, increasing seizure risk. Adverse effects should be managed by consulting the provider to adjust doses or switch medications, not by skipping doses.
Choice E reason: Abruptly discontinuing AEDs can cause rebound seizures due to sudden loss of neuronal stabilization, leading to excitotoxicity. Gradual tapering under medical supervision is required to minimize withdrawal-induced seizures, making this a critical teaching point.

Choice A reason: Diazepam is effective for acute seizures but is less preferred for status epilepticus due to its shorter duration and risk of accumulation with repeated doses. It acts on GABA receptors but is less practical for sustained control in emergencies.
Choice B reason: Midazolam is the drug of choice for status epilepticus due to its rapid onset and short half-life, allowing quick seizure termination via GABA receptor enhancement. Its intramuscular or intranasal administration is practical in emergencies, ensuring prompt control of prolonged seizures.
Choice C reason: Valproic acid is used for long-term seizure management, not acute status epilepticus. Its slower onset and oral/IV administration are less effective for rapid seizure termination, as it modulates sodium channels and GABA but requires time to reach therapeutic levels.
Choice D reason: Carbamazepine is a long-term antiepileptic, not suitable for status epilepticus. It stabilizes sodium channels to prevent seizures but lacks the rapid onset needed for emergency treatment, making it inappropriate for acute, life-threatening seizure activity.
