NRNP 6635 Week 4 Assignment Assessing and Diagnosing Patients With Anxiety Disorders PTSD and OCD

“Fear,” according to the DSM-5-TR, “is the emotional response to real or perceived imminent threat, whereas anxiety is anticipation of future threat” (APA, 2022). All anxiety disorders contain some degree of fear or anxiety symptoms (often in combination with avoidant behaviors), although their causes and severity differ. Trauma-related disorders may also, but not necessarily, contain fear and anxiety symptoms, but their primary distinguishing criterion is exposure to a traumatic event. Trauma can occur at any point in life. It might not surprise you to discover that traumatic events are likely to have a greater effect on children than on adults. Early-life traumatic experiences, such as childhood sexual abuse, may influence the physiology of the developing brain. Later in life, there is a chronic hyperarousal of the stress response, making the individual vulnerable to further stress and stress-related disease.
For this Assignment, you practice assessing and diagnosing patients with anxiety disorders, PTSD, and OCD. Review the DSM-5-TR criteria for the disorders within these classifications before you get started, as you will be asked to justify your differential diagnosis with DSM-5-TR criteria.

To Prepare:
- Review this week’s Learning Resources and consider the insights they provide about assessing and diagnosing anxiety, obsessive-compulsive, and trauma- and stressor-related disorders.
- Download the Comprehensive Psychiatric Evaluation Template, which you will use to complete this Assignment. Also review the Comprehensive Psychiatric Evaluation Exemplar to see an example of a completed evaluation document.
- By Day 1 of this week, select a specific video case study to use for this Assignment from the Video Case Selections choices in the Learning Resources. View your assigned video case and review the additional data for the case in the “Case History Reports” document, keeping the requirements of the evaluation template in mind.
- Consider what history would be necessary to collect from this patient.
- Consider what interview questions you would need to ask this patient.
- Identify at least three possible differential diagnoses for the patient.
By Day 7 of Week 4
Complete and submit your Comprehensive Psychiatric Evaluation, including your differential diagnosis and critical-thinking process to formulate primary diagnosis.
Incorporate the following into your responses in the template:
- Subjective: What details did the patient provide regarding their chief complaint and symptomology to derive your differential diagnosis? What is the duration and severity of their symptoms? How are their symptoms impacting their functioning in life?
- Objective: What observations did you make during the psychiatric assessment?
- Assessment: Discuss the patient’s mental status examination results. What were your differential diagnoses? Provide a minimum of three possible diagnoses with supporting evidence, listed in order from highest priority to lowest priority. Compare the DSM-5-TR diagnostic criteria for each differential diagnosis and explain what DSM-5-TR criteria rules out the differential diagnosis to find an accurate diagnosis. Explain the critical-thinking process that led you to the primary diagnosis you selected. Include pertinent positives and pertinent negatives for the specific patient case.
- Reflection notes: What would you do differently with this client if you could conduct the session over? Also include in your reflection a discussion related to legal/ethical considerations (demonstrate critical thinking beyond confidentiality and consent for treatment!), health promotion and disease prevention taking into consideration patient factors (such as age, ethnic group, etc.), PMH, and other risk factors (e.g., socioeconomic, cultural background, etc.).

Week 4: Training Title 21
Trauma-related disorders are uniquely distinguished by exposure to traumatic events, which can profoundly alter neurobiological development, particularly when experienced during childhood or through repeated exposures such as combat (APA, 2022). Combat veterans face exceptionally high rates of posttraumatic stress disorder (PTSD). This comprehensive psychiatric evaluation examines Sergeant Berry Sullivan, a 27-year-old former Marine who completed three combat tours and now presents with debilitating symptoms following his military separation.
Subjective:
CC (chief complaint): “My fiancée suggested, well demanded that I make an appointment” (Symptom Media, 2016).
HPI: BS, a 27-year-old white male combat veteran who separated from active duty six months ago, presented for evaluation at the insistence of his fiancée following an acute distressing episode at a county fair. He is not currently prescribed any psychotropic medications and presents at the insistence of his fiancée. He is a former Marine (MOS 0800 Field Artillery) who completed eight years of active duty service including three tours in combat zones, separating six months ago. The patient reports experiencing intense fear and panic when exposed to sudden loud noises, particularly explosions or sounds resembling combat fire. At the county fair, unexpected fireworks triggered an immediate flight response where he ran seeking cover, was detained by police, and experienced significant physical symptoms including trembling and requiring assistance. He endorses frequent nightmares every night about combat experiences, causing sleep avoidance. He reports hypervigilance particularly in traffic situations where he fears IED attacks, experiencing sweating, shaking, and difficulty breathing. He describes intrusive memories triggered by diesel fuel and burning smells, specifically recalling two fellow Marines who were burned when their Humvee exploded. The patient reports emotional numbing, social withdrawal, avoidance of public spaces including restaurants and baseball parks, and dissociative episodes where he loses track of time. He experiences increased irritability around conflict and describes feeling like a “coward.” Symptoms have significantly impaired his functioning and quality of life. He denies current substance use and avoids alcohol due to family history.

Diagnostic results:
No laboratory tests are currently recommended for diagnosing PTSD, as diagnosis relies primarily on clinical interview and standardized assessment tools.
