A nurse is assisting in the care of a client who is taking chlorpromazine. Which of the following findings indicates a therapeutic effect medication?

A) Increase in concentration: Chlorpromazine is an antipsychotic medication used to manage symptoms of schizophrenia and other psychotic disorders. While it may have some effects on cognition, an increase in concentration is not the primary therapeutic effect of chlorpromazine. B) Decrease in delusions: Chlorpromazine is effective in reducing symptoms of psychosis, such as delusions and hallucinations, which are common in conditions like schizophrenia. A decrease in delusions is a direct indicator that the medication is having its intended therapeutic effect. C) Increase in alertness: Chlorpromazine can cause sedation and drowsiness as side effects, particularly during the initial stages of treatment. An increase in alertness would not be a typical therapeutic outcome, and it may even suggest a side effect like overstimulation or anxiety rather than the intended effect. D) Decrease in anxiety: While chlorpromazine may have some calming effects, it is primarily used to treat symptoms of psychosis, not anxiety disorders. A decrease in anxiety is not the main therapeutic effect of chlorpromazine. Other medications, such as benzodiazepines, are typically used for anxiety management.
