A 20-year-old client is admitted for treatment of acute schizophrenia and started on risperidone. Which of the following indicates a therapeutic outcome for this medication?
Orthostatic hypotension and sedation
Decreased delusional thinking and lessened audiovisual hallucinations
Restful sleep and increased coping abilities
Decreased anxiety and improved dietary habits
The Correct Answer is B
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.

Correct Answer is A
Explanation
The half-life of a medication is the time it takes for the concentration of the medication in the body to decrease by half. In this case, the medication has a half-life of 2 hours and a current toxic level of 40 mEq/dL. After 2 hours, the level will decrease to 20 mEq/dL. After another 2 hours (4 hours total), the level will decrease to 10 mEq/dL, which is within the normal range. However, it will take another 21 half-lives (42 hours) for the level to reach 5 mEq/dL, which is the lower end of the normal range. Therefore, it will take a total of 25 hours (4 + 21) for the medication to reach the normal range.
Option B is incorrect because it would take much longer than 24 hours for the medication to reach the normal range.
Option C is incorrect because it would only take 2 hours for the medication to decrease by half, not reach the normal range.
Option D is incorrect because it would take longer than 4 hours for the medication to reach the normal range.
