Analyze factors that influence pharmacokinetic and pharmacodynamic processes in clients requiring therapy for impulsivity, compulsivity, and addiction
Week 8: Therapy for Clients With Impulsivity, Compulsivity, and Addiction
Impulsivity and compulsivity have a wide range of clinical presentations and often overlap with many other psychiatric disorders. Some individuals act without forethought and have difficulty saying “no” to certain things such as using illicit drugs or spending money, whereas other individuals engage in compulsive behaviors with undesirable consequences. In some cases, these impulsive and compulsive behaviors also fuel issues with addiction. To effectively assess and treat clients, you must understand how these disorders differ, as well as how their symptoms impact clients and their families.
This week, as you examine therapies for individuals with impulsivity, compulsivity, and addiction, you explore the assessment and treatment of clients with these disorders. You also consider ethical and legal implications of these therapies.

Assignment: Assessing and Treating Clients With Impulsivity, Compulsivity, and Addiction
Impulsivity, compulsivity, and addiction are challenging disorders for clients across the lifespan. These disorders often manifest as negative behaviors, resulting in adverse outcomes for clients. In your role as the psychiatric mental health nurse practitioner, you have the opportunity to help clients address underlying causes of the disorders and overcome these behaviors. 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 impulsivity, compulsivity, and addiction.

Note: This case study will serve as the foundation for this week’s Assignment.

To prepare for this Assignment:
Review this week’s Learning Resources. Consider how to assess and treat adolescent clients requiring therapy for impulsivity, compulsivity, and addiction.
The Assignment
Examine Case Study: A Puerto Rican Woman With Comorbid Addiction. 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?
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.
Co-morbid Addiction (ETOH and Gambling)
53-year-old Puerto Rican Female
BACKGROUND
Mrs. Maria Perez is a 53 year old Puerto Rican female who presents to your office today due to a rather “embarrassing problem.”
SUBJECTIVE
Mrs. Perez admits that she has had “problems” with alcohol since her father died in her late teens. She reports that she has struggled with alcohol since her 20’s and has been involved with Alcoholics Anonymous “on and off” for the past 25 years. She states that for the past two years, she has been having more and more difficulty maintaining her sobriety since they opened the new “Rising Sun” casino near her home. Mrs. Perez states that she and a friend went to visit the new casino during their grand opening at which point she was “hooked.” She states that she gets “such a high” when she is gambling. While gambling, she “enjoys a drink or two” to help calm her during high-stakes games. She states that this often gives way to more drinking and more reckless gambling. She also reports that her cigarette smoking has increased over the past two years and she is concerned about the negative effects of the cigarette smoking on her health.
She states that she attempts to abstain from drinking but that she gets such a “high” from the act of gambling that she needs a few drinks to “even out.” She also notices that when she drinks, she doesn’t smoke “as much” but enjoys smoking when she is playing at the slot machines. She also reports that she has gained weight from drinking so much- she currently weights 122 lbs., which represents a 7 lb. weight gain from her usual 115 lb. weight.
Mrs. Perez is quite concerned today because she has borrowed over $50,000 from her retirement account to pay off her gambling debts. She is very concerned because her husband does not know that she has spent this much money.
MENTAL STATUS EXAM
The client is a 53 year old Puerto Rican female who is alert, oriented to person, place, time, and event. She is dressed appropriately for the weather and time of year. Her speech is clear, coherent, and goal directed. Her eye contact is somewhat avoidant during the clinical interview. As you make eye contact with her, she looks away or looks down. She demonstrates no noteworthy mannerisms, gestures, or tics. Her self-reported mood is “sad.” Affect is appropriate to content of conversation & self-reported mood. She visual or auditory hallucinations, no delusional or paranoid thought processes are readily appreciated. Insight and judgment are grossly intact, however, impulse control is impaired. She is currently denying suicidal or homicidal ideation.
Diagnosis: Gambling disorder, alcohol use disorder
Decision Point One
Select what the PMHNP should do:

Naltrexone (Vivitrol) injection, 380 mg intramuscularly in the gluteal region every 4 weeks

Antabuse (Disulfiram) 250 mg orally daily

Campral (Acamprosate) 666 mg orally three times/day
Co-morbid Addiction (ETOH and Gambling)
53-year-old Puerto Rican Female
Decision Point One
Naltrexone (Vivitrol) injection, 380 mg intramuscularly in the gluteal region every 4 weeks
RESULTS OF DECISION POINT ONE
Client returns to clinic in four weeks
Mrs. Perez said that she felt “wonderful” as she has not “touched a drop” to drink since receiving the injection
Client reports that she has not been going to the casino, as frequently, but when she does go she “drops a bundle” (meaning, spends a lot of money gambling)
Client She is also still smoking, which has her concerned. She is also reporting some problems with anxiety, which also have her concerned
Decision Point Two
Refer to a counselor to address gambling issues

RESULTS OF DECISION POINT TWO
Client returns to clinic in four weeks
Client reports that the anxiety that she had been experiencing is gone
Client reports that she has met with the counselor, but did not really like her. She did start going to a local meeting gamblers anonymous. She stated that last week, for the first time, she spoke during the meeting. She reports feeling supported in this group
Decision Point Three

Explore the issue that Mrs. Perez is having with her counselor, and encourage her to continue attending the Gamblers Anonymous meetings

Guidance to Student

Although controversy exists in the literature regarding how long to maintain a client on Vivitrol, four weeks is probably too soon to consider discontinuation. The psychiatric mental health nurse practitioner should explore the issues that Mrs. Perez is having with her counselor. As you will learn in future courses, ruptures and the therapeutic alliance can result in clients stopping therapy. Clearly, if the client does not continue with therapy, the likelihood of the gambling problem spontaneously remitting is lower (than had the client continued to receive therapy). Recall that there are no FDA approved treatments for gambling addiction, and the mainstay of treatment for this disorder is counseling. Since Mrs. Perez reports good perceived support from the gamblers anonymous meetings, she should be encouraged to continue her participation with this group.
The PMHNP needs to discuss smoking cessation options with Mrs. Perez in order to address the totality of addictions, and to enhance her overall health.
