The Case Study:
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

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
Decision Point One
SELECTED: Begin Risperdal 1 mg orally BID
RESULTS OF DECISION POINT ONE
Client returns to clinic in four weeks

Client’s mother explains that “she has been like this since about a week after the last office visit”
Please include the reasons why not using the other two medications as my decision one
Decision Point Two
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
Decision Point Two
SELECTED : Decrease Risperdal to 1 mg at HS
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)
Please include the reasons why not using the other two medications as my decision one
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
Decision Point Three
SELECTED: Continue at same dose of Risperdal and reassess in 4 weeks
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.
