DSM-5 Diagnosis and Ethics in Psychiatric Nursing Practice

~7 min read 5 sections Therapy
Abstract

This paper presents a clinical case formulation for a 36-year-old Hispanic male experiencing symptoms of depression, and applies DSM-5 diagnostic criteria to arrive at a differential diagnosis. The paper systematically evaluates major depressive disorder and bipolar II disorder as diagnostic candidates, ultimately supporting a diagnosis of severe major depressive disorder, single episode. It further examines three core ethical and legal issues psychiatric mental health nurse practitioners (PMHNPs) encounter when treating clients with psychiatric disorders: maintaining patient confidentiality under HIPAA, balancing family involvement in treatment planning, and navigating the ethical tensions surrounding involuntary treatment.

Key Takeaways
  • Client Presentation and Case Background: Demographics, chief complaint, history, and case formulation
  • DSM-5 Criteria for Major Depressive Disorder: Eight DSM-5 diagnostic criteria for MDD listed
  • Differential Diagnosis: Bipolar II Disorder: DSM-5 criteria for bipolar II hypomanic episode examined
  • Final Diagnosis and Clinical Rationale: MDD severe single episode confirmed; bipolar II ruled out
  • Ethical and Legal Issues in Psychiatric Treatment: Confidentiality, family involvement, and involuntary treatment discussed

What makes this paper effective

  • Follows a structured clinical format — chief complaint, history, case formulation, differential diagnosis — mirroring real psychiatric practice documentation.
  • Uses DSM-5 criteria explicitly and systematically, demonstrating that the client meets criteria for one diagnosis but not the other, rather than simply asserting a conclusion.
  • Connects legal and ethical discussion to the specific clinical scenario, grounding abstract principles (confidentiality, autonomy) in practical PMHNP decision-making.

Key academic technique demonstrated

This paper demonstrates criterion-based differential diagnosis reasoning. By listing all DSM-5 criteria for both major depressive disorder and bipolar II disorder, then mapping each symptom from the case to the relevant criterion, the writer shows a systematic rule-in/rule-out approach rather than relying on general description. This is the standard evidence-based technique in clinical documentation and academic psychiatric case presentations.

Structure breakdown

The paper opens with a client vignette (demographics, chief complaint, illness history, medications, and social context), then moves into a two-part differential diagnosis section that applies DSM-5 criteria before arriving at a final diagnosis. The second half shifts to ethical and legal analysis, covering confidentiality, family involvement, and involuntary treatment as discrete issues. References follow APA format throughout.

Client Presentation and Case Background

The client is a 36-year-old male of Hispanic origin who came to the United States as a teenager and currently resides with his mother in a mid-income neighborhood.

Chief Complaint: The client reports endorsed feelings of depression, insomnia, feelings of worthlessness, loss of interest in routine activities, sudden unexplained weight loss, and an inability to concentrate at work.

History of Current Illness: The client has no history of traumatic childhood experiences or abuse. He does, however, have a history of major depressive disorder, for which he previously received treatment. There is no history of psychiatric illness in the client's family, and previous medical workup indicates that his depression has no organic basis. His depression is attributable to the bullying and discrimination he experienced in high school due to his immigrant status. An EKG performed today is normal and his BMI is within normal range. From the mental status examination, he appears alert and oriented, with judgment and insight intact, and a broad affect throughout the interview. He denies experiencing paranoid thought processes, hallucinations, or suicidal ideation.

Allergies: NKDA

Psychiatric History: Major depressive disorder

Medications: Zoloft 25 mg daily and Wellbutrin XR 150 mg daily

Social History: The client lost his father at a young age and has been living with his mother since. He shares a strong relationship with her and reports that she has always been present to help him confront his fears and adequately manage his emotions.

Case Formulation: Since high school, the client has been a victim of discrimination based on his immigrant status. He struggles to achieve success in a system that discriminates against racial minorities. Given the social disorganization and lack of formal institutions in most immigrant communities, stable employment has been difficult to obtain. Aged 36 and still living with his mother, the client feels stagnated, worthless, and sad.
