A nurse is planning care for a client who takes haloperidol for the treatment of schizophrenia. Which of the following should the nurse include in the plan of care?

A. Monitor the client for hypothermia: Hypothermia is not a typical adverse effect of haloperidol. The medication more commonly causes extrapyramidal symptoms and neuroleptic malignant syndrome, which may include hyperthermia rather than hypothermia. B. Screen the client for tardive dyskinesia: Tardive dyskinesia is a serious, potentially irreversible extrapyramidal side effect associated with long-term use of antipsychotics such as haloperidol. Routine screening using tools like the Abnormal Involuntary Movement Scale (AIMS) is essential to detect early signs and adjust therapy as needed. C. Check the client's weekly potassium level: Haloperidol does not typically affect potassium levels. Routine electrolyte monitoring is not indicated unless the client has other conditions or is taking medications that affect potassium. D. Schedule the client for a 24-hr urine collection: A 24-hour urine collection is unrelated to haloperidol therapy. This test is used to assess kidney function or specific metabolic conditions and is not part of routine care for clients taking antipsychotics.
