CASE STUDY:
Week 4: Bipolar Therapy
Jay, an 18-year-old high school senior, presents with symptoms of difficulty sleeping and feeling sad, which results in an initial diagnosis of depression. His mother later reports, however, that Jay exhibits symptoms of irritability and risk-taking behaviors. (His little brother reported to his mother that they were driving over 90 miles an hour on the highway.) After further evaluation, Jay’s psychiatric mental health nurse practitioner diagnosed him with bipolar disorder.
Cases like this are not uncommon with bipolar disorder, as initial assessments rarely provides all the information needed. In your role, as a psychiatric mental health nurse practitioner, you must develop strategies for properly assessing and diagnosing these clients because treatments for bipolar disorder are significantly different than treatments for depression or other mood disorders.
This week, as you examine bipolar therapies, you explore the assessment and treatment of clients with bipolar disorder. You also consider ethical and legal implications of these therapies.

Assignment: Assessing and Treating Clients with With Bipolar Disorder
Bipolar disorder is a unique disorder that causes shifts in mood and energy, which results in depression and mania for clients. Proper diagnosis of this disorder is often a challenge for two reasons: 1) clients often present as depressive or manic, but may have both; and 2) many symptoms of bipolar disorder are similar to other disorders. Misdiagnosis is common, making it essential for you to have a deep understanding of the disorder’s pathophysiology. 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 bipolar disorder.
Learning Objectives
Students will:
- Assess client factors and history to develop personalized plans of bipolar therapy for clients
- Analyze factors that influence pharmacokinetic and pharmacodynamic processes in clients requiring bipolar therapy
- Evaluate efficacy of treatment plans
- Analyze ethical and legal implications related to prescribing bipolar 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 bipolar therapy.
The Assignment
Examine Case Study: An Asian American Woman With Bipolar Disorder. 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
- Which decision did you select?
- Why did you select this decision? Support your response with evidence and references to the Learning Resources.
- What were you hoping to achieve by making this decision? Support your response with evidence and references to the Learning Resources.
- Explain any difference between what you expected to achieve with Decision #1 and the results of the decision. Why were they different?
- Decision #2
- Why did you select this decision? Support your response with evidence and references to the Learning Resources.
- What were you hoping to achieve by making this decision? Support your response with evidence and references to the Learning Resources.
- Explain any difference between what you expected to achieve with Decision #2 and the results of the decision. Why were they different?
- Decision #3
- Why did you select this decision? Support your response with evidence and references to the Learning Resources.
- What were you hoping to achieve by making this decision? Support your response with evidence and references to the Learning Resources.
- 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.
Submission and Grading Information
CASE STUDY
Client of Korean Descent/Ancestry
BACKGROUND INFORMATION
The client is a 26-year-old woman of Korean descent who presents to her first appointment following a 21-day hospitalization for onset of acute mania. She was diagnosed with bipolar I disorder.
Upon arrival in your office, she is quite “busy,” playing with things on your desk and shifting from side to side in her chair. She informs you that “they said I was bipolar, I don’t believe that, do you? I just like to talk, and dance, and sing. Did I tell you that I liked to cook?”
She weights 110 lbs. and is 5’ 5”
SUBJECTIVE
Patient reports “fantastic” mood. Reports that she sleeps about 5 hours/night to which she adds “I hate sleep, it’s no fun.”
You reviewed her hospital records and find that she has been medically worked up by a physician who reported her to be in overall good health. Lab studies were all within normal limits. You find that the patient had genetic testing in the hospital (specifically GeneSight testing) as none of the medications that they were treating her with seemed to work.
Genetic testing reveals that she is positive for CYP2D6*10 allele.
Patient confesses that she stopped taking her lithium (which was prescribed in the hospital) since she was discharged two weeks ago.
MENTAL STATUS EXAM
The patient is alert, oriented to person, place, time, and event. She is dressed quite oddly- wearing what appears to be an evening gown to her appointment. Speech is rapid, pressured, tangential. Self-reported mood is euthymic. Affect broad. Patient denies visual or auditory hallucinations, no overt delusional or paranoid thought processes readily apparent. Judgment is grossly intact, but insight is clearly impaired. She is currently denying suicidal or homicidal ideation.
The Young Mania Rating Scale (YMRS) score is 22

1. Decision Point One
Select what the PMHNP should do:
Begin Lithium 300 mg orally BID
Begin Risperdal 1 mg orally BID
Begin Seroquel XR 100 mg orally at HS
SELECTED ANSWER: Begin Risperdal 1 mg orally BID
Decision 2
Bipolar Therapy
Client of Korean Descent/Ancestry
2. Decision Point Two
RESULTS OF DECISION POINT ONE
- Client returns to clinic in four weeks
- Client is accompanied today by her mother who must help the client into your office, the client looks very sedated and lethargic
- Client’s mother explains that “she has been like this since about a week after the last office visit”
Select what the PMHNP should do next:
Discontinue Risperdal and start Lithium sustained release 300 mg orally BID
Decrease Risperdal to 1 mg at HS
Change Risperdal to 2 mg at HS
Answer selected: Decrease Risperdal to 1 mg at HS
Decision Point THREE
RESULTS OF DECISION POINT TWO
- Client returns to clinic in four weeks
- Client is less sedate, less lethargic and shows symptom improvement
- Young Mania Rating Scale has decreased from 22 to 16 (a bit more than a 25% decrease in symptoms)
Decision Point Three
Select what the PMHNP should do next:
Continue at same dose of Risperdal and reassess in 4 weeks
Increase Risperdal back to 1 mg orally BID
Change to Latuda 40 mg orally daily
Selected answer: Continue at same dose of Risperdal and reassess in 4 weeks
RESULTS FOR DECISION THREE AND SUMMARY
Guidance to Student
At this point, the PMHNP may be wise to allow the client to remain at the same dose and reassess in 4 weeks. Recall that the client is of Korean descent and is positive for CYP2D6*10 allele. As a result, she may have slower clearance of Risperdal from her system, which may have resulted in higher than normal levels of Risperdal in the blood, which in turn resulted in sedation. Therefore, if we were to increase back to 1 mg orally BID, she may have the same side effects. Latuda is FDA approved for bipolar I depression, which is not the presentation we are attempting to treat. Additionally, it is quite expensive and many insurance companies will not pay for it until other agents have been attempted and failed.
