A nurse is caring for a client who has a prescription for chlorpromazine. Which of the following findings should the nurse identify as an indication that the medication is effective?

A: Incorrect. Decreased blood pressure is not an indication of chlorpromazine effectiveness, but rather a potential adverse effect that should be monitored and reported. B: Correct. Decreased hallucinations are an indication of chlorpromazine effectiveness, as this medication is an antipsychotic that blocks dopamine receptors in the brain and reduces psychotic symptoms such as hallucinations, delusions, and paranoia. C: Incorrect. Decreased cholesterol is not an indication of chlorpromazine effectiveness, but rather a potential benefit that may occur due to its effect on lipid metabolism. D: Incorrect. Decreased esophageal reflux is not an indication of chlorpromazine effectiveness, but rather a potential adverse effect that should be avoided by taking the medication with food or water and avoiding lying down after administration.
