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. Delusional Disorders
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.

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.
Delusional Disorders Pakistani Female With Delusional Thought Processes
Decision Point One
Start Invega Sustenna 234 mg intramuscular X1 followed by 156 mg intramuscular on day 4 and monthly thereafter
RESULTS OF DECISION POINT ONE
· Client returns to clinic in four weeks
· A decrease in PANSS score of 25% is noted at this visit
· Client seems to be tolerating medication
· Client’s husband has made sure she makes her appointments for injections (one thus far)
· Client has noted a 2 pound weight gain but it does not seem to be an important point for her
· Client complains of injection site pain telling the PMHNP that she has trouble siting for a few hours after the injections and doesn’t like having to walk around for such a long period of time
Decision Point Two
Continue same decision made but instruct administering nurse to begin injections into the deltoid at this visit and moving forward Delusional Disorders
RESULTS OF DECISION POINT TWO
· Client returns to clinic in four weeks
· Client’s PANNS has reduced by a total of 50% from the initiation of Invega sustenna
· When questioned about injection site pain, client states it is much better in the arm
· Client’s weight has increased by an additional 2.5 pounds (total of 4.5 pounds in a 2 month period). She is somewhat bothered by the weight gain and is afraid that her husband does not like it. He is not present at this visit as she brought herself
· Client likes how she feels on the Invega Sustenna but is wondering if there is another drug like it that would not cause the weight gain
Decision Point Three
Continue with the Invega Sustenna. Counsel client on the fact that weight gain from Invega Sustenna is not as much as what other drugs with similar efficacy can cause. Make appointment with a dietician and an exercise physiologist. Follow up in one month
Guidance to Student
Weight gain can occur with Invega Sustenna. It is modest in nature and can be controlled with proper nutrition and exercise. It is always a good idea to try and control a client’s weight through consultation with a dietician and exercise physiologist (life coach) before switching to another agent when a product is showing efficacy for at least 6 months.
Abilify Maintena is a good option for someone who has good response to abilify oral. Remember that Abilify does not bind to the D2 receptor for a great period of time (such as Invega) and can be less affective in certain individuals. Also, remember that akathisia can be a possible side effect. Once an IM long acting medication is given, the effects of the drug (both efficacious and untoward effects) can be maintained for a long duration (up to a month or longer). Tolerability and efficacy should be established with oral medication first before administering the first injection. Also a disadvantage to Abilify Maintena is a 2-week overlap of oral therapy is required due to effective blood levels lagging behind the induction dose.
Qsymia is a weight loss medication that is a combination of Phenteramine and Topiramate. It is only indicated to treat obesity. This client’s BMI (28.9 kg/M2) does not fit the definition of obesity (BMI >30 Kg/M2- Following from CDC website: Class 1: BMI of 30 to < 35, Class 2: BMI of 35 to < 40, Class 3: BMI of 40 or higher. Class 3 obesity is sometimes categorized as “extreme” or “severe” obesity). There are two things wrong with this therapy option. First, there are only a few occasions where add-on therapy to treat a side effect is acceptable and weight gain is not one of those scenarios. Secondly, Phenteramine has a lot of cardiovascular toxicities (such as elevated BP, HR, increased workload on the heart). Delusional Disorders
