A patient begins therapy with clozapine medication. What teaching should the nurse provide related to the drug’s strong dopaminergic effect?

Choice A reason: Weight gain and metabolic changes are side effects of clozapine, primarily due to its antihistaminic and serotonergic effects, not its dopaminergic action. Dopamine blockade is more associated with movement disorders, making this choice incorrect for teaching related to dopaminergic effects. Choice B reason: Clozapine’s strong dopaminergic effect, particularly D2 receptor blockade, can cause extrapyramidal symptoms like tardive dyskinesia, a movement disorder. Patient education must emphasize monitoring for abnormal movements, as these are significant risks in antipsychotic therapy, making this the correct choice. Choice C reason: Infection risk, particularly agranulocytosis, is a serious clozapine side effect but is unrelated to its dopaminergic action. It stems from bone marrow suppression, requiring blood monitoring, not dopamine-related teaching, making this choice incorrect for the question’s focus. Choice D reason: Improved mood is not a direct result of clozapine’s dopaminergic effect, which primarily addresses psychotic symptoms. Mood changes occur over weeks and involve multiple receptors, not just dopamine, making this choice incorrect for dopaminergic-focused teaching.
