An agitated, extremely anxious client is brought to the emergency department and the provider orders alprazolam. The nurse understands alprazolam is appropriate to administer in this situation due to which of the following reasons?

Carbidopa/levodopa is a medication used to treat the symptoms of Parkinson's disease, including tremors, stiffness, and difficulty with movement. If the medication is effective, the client should show improvement in their ability to move and perform daily activities. In this case, the client being able to walk upright without stumbling indicates that the medication is effective.
Option B is incorrect because eating 30% to 40% of meals within 1 hour is not related to the effectiveness of carbidopa/levodopa.
Option C is incorrect because displaying emotions when discussing the illness is not related to the effectiveness of carbidopa/levodopa.
Option D is incorrect because cogwheel motion when swinging the arms is a symptom of Parkinson's disease and would indicate that the medication is not effective.

Risperidone is an atypical antipsychotic medication used to treat schizophrenia ¹. It works by changing the activity of certain natural substances in the brain ¹. A therapeutic outcome for this medication would be a decrease in symptoms of schizophrenia such as delusional thinking and audiovisual hallucinations ¹.
Option A is not correct because orthostatic hypotension and sedation are side effects of risperidone, not therapeutic outcomes ¹.
Option C is not correct because restful sleep and increased coping abilities are not specific therapeutic outcomes for risperidone in the treatment of schizophrenia.
Option D is not correct because decreased anxiety and improved dietary habits are not specific therapeutic outcomes for risperidone in the treatment of schizophrenia.
