I want this assignment asap -PLAGIARISM MUST BE LESS THAN 10%
sychosis 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:
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:
Case 2: Volume 2, Case #11: The figment of a man who looked upon the lady
Briefly, this is a scenario of a 42 year- old woman with a complex psychiatric history extending from depression, posttraumatic stress disorder, insomnia, visual hallucinations (little man)and impaired behavior with aggression. In the course of more than 36 months, the client was treated with Paroxetine (SSRI), Bupropion ( NDRI), Tiagabine, Ramelteon and , but finally a combination of Lexapro, Bupropion and quetiapine was able to decrease her symptoms . The client’s medical history includes diabetes, hypertension, CAD, hyperlipidemia, COPD, OSA, GERD, Glaucoma, overweight and a remote history of substance abuse.

Certain medications or supplements can cause symptoms of mental illness and also due to her extensive medical history and usage of multiple medications I would ask the following questions:
1. Do you take any over -the – counter, herbal supplements or remedies and I would check for interactions with current medication regimen?
2. When and how often do you use your albuterol inhaler ? Some of the side effects of albuterol include anxiety, nervousness, and insomnia ( Cunha, 2016)
Sleep Hygiene: Do you keep regular sleep schedule ? Do you drink caffeine beverages close to bedtime?
The patient may not be a reliable source of information, particularly that she has a significant mental illness that affects her functioning, hence verifying her responses with her direct family members, and mental social workers to get clues to the underlying or precipitating causes of mental crisis. Also checking facility records from previous encounters, or any psychiatric hospitalizations would be useful.
1. Thyroid Stimulating Hormone (TSH). Based on recent evidence, the prevalence of depressive symptoms in hypothyroidism was nearly 50%, and clinical depression occurs in more than 40% of people suffering from hypothyroidism ( Bhagwat, 2017)
2. Electrocardiogram (ECG) The client has cardiovascular diseases ( HTN, CAD), with risks of cardio complications. In the setting of taking antidepressants and antipsychotics, baseline ECG and possibly every three to six months would be appropriate. Several atypical antipsychotics including quetiapine (Seroquel) are known to cause prolongation of the QT interval, hypothesized to occur via direct inhibition of the cardiac delayed potassium rectifier channel, which extends the ventricular repolarization process (Zhai et al., 2017)
1. Posttraumatic Stress Disorder ( PTSD)_
2. Major Depressive Disorder (MDD)
3. Insomnia Disorder.
Pharmacotherapy Options for Sleep/ Wake cycle
1. Zolpidem (Ambien) 5mg oral at bedtime for Seven days.
Zolpidem is nonbenzodiazepine hypnotic, it works by enhancing GABA inhibitory actions that provide sedative hypnotic effects more selectively than other actions of GABA (Stahl, 2017). With its side effects of sedation, low dose prescribed as the client has respiratory problems (sleep apnea OSA)). Studies have shown that Zolpidem did not significantly worsen OSA as measured by the numbers and duration of pauses in breathing during sleep, but in one trial, it significantly lowered minimum oxygen levels during the night when compared with placebo ( Mason & Smith, 2015).
2. Trazadone 25 mg oral at bedtime for Thirty days.
Trazadone is a serotonin 2 antagonist/reuptake inhibitor, used in management of depression and insomnia. It is absorbed well, metabolized by CYP 450 3A4 with average half life of 6hrs. It has less side sedative effects compared to zolpidem (Stahl, 2017)
The best choice for the client would be Trazadone as there is no reliable evidence of dependence or withdraws and it can also work for the client’s depression.
