RATIONALE: Fluphenazine decanoate is a long-acting antipsychotic agent given by injection. Because it has a 4-week duration of action, it's commonly prescribed for outpatients with a history of medication noncompliance. Chlorpromazine, also an antipsychotic agent, must be administered daily to maintain adequate plasma levels, which necessitates compliance with the dosage schedule. Imipramine, a tricyclic antidepressant, and lithium carbonate, a mood stabilizer, are rarely used to treat clients with chronic schizophrenia.NURSING PROCESS STEP: PlanningCLIENT NEEDS CATEGORY: Physiological integrityCLIENT NEEDS SUBCATEGORY: Pharmacological and parenteral therapiesCOGNITIVE LEVEL: Knowledge
