Final answer:
Antipsychotic medications are effective in the treatment of Tourette's disorder, as they can help reduce the severity and frequency of tics.
Step-by-step explanation:
When planning care for a client with Tourette's disorder, a nurse should recognize antipsychotic medications as effective in the treatment. Antipsychotics such as clozapine and risperidone are commonly used to manage symptoms associated with Tourette's disorder, such as tics, obsessive-compulsive symptoms, and aggression. These medications work by modulating dopamine levels in the brain and can help reduce the severity and frequency of tics.
