A patient is prescribed 100 mg of Clozapine daily. The available tablet strength is 25 mg. How many tablets should the nurse administer?

Choice A reason: Four tablets (100 mg) match the prescribed Clozapine dose. This antipsychotic stabilizes dopamine and serotonin in schizophrenia. Scientifically, accurate dosing ensures therapeutic receptor antagonism, controlling psychotic symptoms without toxicity, supporting mental health stability by addressing neural hyperactivity effectively in treatment. Choice B reason: Three tablets (75 mg) underdose the prescribed 100 mg. Clozapine’s efficacy relies on sufficient receptor blockade. Scientifically, subtherapeutic dosing fails to control dopamine-driven symptoms, risking persistent psychosis or hallucinations, as inadequate levels don’t stabilize neural activity, compromising schizophrenia management. Choice C reason: Five tablets (125 mg) exceed the prescribed dose, risking toxicity. Clozapine overdosing can cause agranulocytosis or seizures due to excessive receptor antagonism. Scientifically, precise dosing prevents severe side effects, ensuring safe treatment by maintaining therapeutic levels for effective schizophrenia symptom control. Choice D reason: Two tablets (50 mg) significantly underdose the required 100 mg. Scientifically, insufficient Clozapine fails to modulate dopamine and serotonin, risking persistent psychotic symptoms. This compromises treatment efficacy, as subtherapeutic levels don’t address neural hyperactivity, delaying recovery in schizophrenia management.
