A client with schizophrenia has received standard antipsychotics for a year. His hallucinations are less intrusive, but the client remains apathetic, has poverty of thought, cannot work, and is socially isolated.
To address these symptoms, the nurse might expect the psychiatrist to prescribe which medication?
Haloperidol
Olanzapine
Diphenhydramine
Chlorpromazine
The Correct Answer is B
A. Haloperidol is a first-generation antipsychotic and may not be as effective in addressing the negative symptoms (e.g., apathy, poverty of thought) as second-generation antipsychotics.
B. Olanzapine is a second-generation antipsychotic known to be effective in treating both positive and negative symptoms of schizophrenia.
C. Diphenhydramine is not typically used as a primary treatment for schizophrenia.
D. Chlorpromazine is a first-generation antipsychotic and may not be as effective in addressing the negative symptoms as second-generation antipsychotics.

Explanation
A. Delirium is characterized by a fluctuating level of consciousness, which can include periods of hypervigilance.
B. A slow onset of confusion and agitation is more characteristic of dementia rather than delirium.
C. A decrease in output and vital signs may indicate a different condition, but it is not specific to delirium.
D. Delirium is characterized by an acute onset and is typically short-lived, usually lasting days to weeks. Symptoms lasting longer than a month would suggest a different diagnosis.
Correct Answer is A
Explanation
A. Increase your fluid and fiber intake to prevent constipation – Risperidone, an atypical antipsychotic, can cause constipation due to its anticholinergic effects. Increasing fluid and fiber intake can help prevent this.
B. Have your blood pressure checked frequently for hypertension – Risperidone is more commonly associated with orthostatic hypotension, not hypertension.
C. Expect to have your blood checked weekly for serum electrolyte imbalances – Unlike clozapine, risperidone does not require frequent blood monitoring for electrolyte imbalances.
D. Increase caloric intake to prevent weight loss – Risperidone is more likely to cause weight gain rather than weight loss, so increasing caloric intake is unnecessary.
