Week 6: Antipsychotic Therapy
According to the National Alliance on Mental Illness, approximately 100,000 people experience psychosis in the United States each year (NAMI, 2016). In practice, clients may present with delusions, hallucinations, disorganized thinking, disorganized or abnormal motor behavior, as well as other negative symptoms that can be disabling for these individuals. Not only are these symptoms one of the most challenging symptom clusters you will encounter, many are associated with other disorders such as depression, bipolar disorder, and disorders on the schizophrenia spectrum. As a psychiatric mental health nurse practitioner, you must understand the underlying neurobiology of these symptoms to select appropriate therapies and improve outcomes for clients.
This week, as you examine antipsychotic therapies, you explore the assessment and treatment of clients with psychosis and schizophrenia. You also consider ethical and legal implications of these therapies.

Assignment: Assessing and Treating Clients With Psychosis and Schizophrenia
Psychosis and schizophrenia greatly impact the brain’s normal processes, which interferes with the ability to think clearly. When symptoms of these disorders are uncontrolled, clients may struggle to function in daily life. However, clients often thrive when properly diagnosed and treated under the close supervision of a psychiatric mental health practitioner. For this Assignment, as you examine the client case study in this week’s Learning Resources, consider how you might assess and treat clients presenting with psychosis and schizophrenia.
Learning Objectives
Students will:
· Assess client factors and history to develop personalized plans of antipsychotic therapy for clients
· Analyze factors that influence pharmacokinetic and pharmacodynamic processes in clients requiring antipsychotic therapy
· Evaluate efficacy of treatment plans
· Analyze ethical and legal implications related to prescribing antipsychotic therapy to clients across the lifespan

To prepare for this Assignment:
· Review this week’s Learning Resources. Consider how to assess and treat clients requiring anxiolytic therapy.
The Assignment
Examine Case Study: Pakistani Woman with Delusional Thought Processes. You will be asked to make three decisions concerning the medication to prescribe to this client. Be sure to consider factors that might impact the client’s pharmacokinetic and pharmacodynamic processes.
At each decision point stop to complete the following:
· Decision #1
o Which decision did you select?
o Why did you select this decision? Support your response with evidence and references to the Learning Resources.
o What were you hoping to achieve by making this decision? Support your response with evidence and references to the Learning Resources.
o Explain any difference between what you expected to achieve with Decision #1 and the results of the decision. Why were they different?
· Decision #2
o Why did you select this decision? Support your response with evidence and references to the Learning Resources.
o What were you hoping to achieve by making this decision? Support your response with evidence and references to the Learning Resources.
o Explain any difference between what you expected to achieve with Decision #2 and the results of the decision. Why were they different?
· Decision #3
o Why did you select this decision? Support your response with evidence and references to the Learning Resources.
o What were you hoping to achieve by making this decision? Support your response with evidence and references to the Learning Resources.
o Explain any difference between what you expected to achieve with Decision #3 and the results of the decision. Why were they different?
Also include how ethical considerations might impact your treatment plan and communication with clients.
Note: Support your rationale with a minimum of three academic resources. While you may use the course text to support your rationale, it will not count toward the resource requirement.
