Week 7 Assignment: Differential Case Presentations

Week 7 Assignment Differential Case Presentationsvaluecompleteincom

Without looking back at your text, readings etc., read the patient case studies below. List 3 differential diagnosis for each and why you believe these to be solid options that should be considered by the provider. Copy and paste the patient scenarios into a word document and use bullet points below each patient for your differential diagnosis and then upload to the assignment section. Below is an example Patient X: 7-year-old Hispanic male with a cough and temperature of 99.9F · Differential Dx: · Allergic rhinitis · URI · Pneumonia Patients Patient 1: 28-year-old woman with opioid use disorder; uses IV heroin; has PTSD; no other medical problems or medications. She currently is single , lives with several roommates, and has a history of legal problems (with some jail time). Sexually active with men and women ; inconsistent use of protection. Patient 2: 70-year-old man with history of CHF, COPD, and HTN; currently smokes one pack of cigarettes daily; takes Lisinopril, Digoxin, and Symbicort daily. Married to wife of 30 years and is retired (previously an accountant), is supported by adult children, and lives with wife in home. Patient 3: 40-year-old woman with a history of breast cancer that was successfully treated with Tamoxifen for several months. Otherwise healthy, with no other issues at this time. She is a successful businesswoman in a high-profile career with much stress. Married to wife of four years; relationship is rocky at times. Denies any substance use; travels frequently. Symptoms are the same for all 3 patients: · Shortness of breath · Chest pain · Flank pain · Fever Note: In Part 2, due Week 10, you will revisit these same three patient scenarios. Using your knowledge of pathophysiology, the course learning materials, and research, you will compare and contrast your original 3 differential diagnosis submitted during Week 7 to your final 3 differential diagnosis. Are they the same? Do you have a different perspective or ideas about what should be your primary differential for these scenarios? See Week 10 for further instructions. To Submit Your Assignment: 1.

Paper For Above instruction

The differential diagnosis process is a critical component in clinical decision-making, especially when faced with patients presenting similar symptoms. In this assignment, three patient scenarios are provided, each with symptoms of shortness of breath, chest pain, flank pain, and fever. Analyzing potential causes requires a comprehensive understanding of pathophysiology, epidemiology, and clinical presentation. This paper aims to identify three plausible differential diagnoses for each patient, justify these choices, and prepare for a comparative review in Week 10.

Patient 1: 28-year-old woman with opioid use disorder

The first patient is a young woman with a history of IV heroin use, PTSD, and no other significant medical problems. She lives with roommates and has a history that includes legal issues. Her symptoms—shortness of breath, chest pain, flank pain, and fever—necessitate considering causes linked to her substance use and social situation.

• Pneumothorax: Heroin use, especially via IV, increases her risk of spontaneous pneumothorax due to potential barotrauma or needle-related lung injury. A pneumothorax can cause sudden chest pain and shortness of breath.
• Infective Endocarditis: IV drug use predisposes her to endocarditis, which can produce systemic symptoms like fever and chest discomfort, with possible embolic phenomena affecting lungs (septic emboli leading to pulmonary infiltrates).
• Pneumonia: Given her social circumstances and potential for compromised immune status, bacterial pneumonia remains a possibility, especially if injection practices introduce pathogens.

Patient 2: 70-year-old man with multiple comorbidities

This patient is an elderly man with a history of congestive heart failure (CHF), COPD, and hypertension. He smokes and takes multiple medications. His age and comorbidities influence his risk forcardiopulmonary and infectious processes.

• Acute Exacerbation of COPD: With a previous COPD diagnosis and current smoking status, his symptoms could be due to a flare-up caused by infection or environmental factors, resulting in increased dyspnea and fever.
• Pulmonary Embolism (PE): Chest pain and shortness of breath in elderly patients with limited mobility or comorbidities increase PE risk; emboli could cause infarction with fever due to inflammatory response.
• Heart Failure Exacerbation: His history of CHF makes fluid overload and pulmonary edema a primary consideration, especially with nocturnal dyspnea, orthopnea, and crackles on exam.

Patient 3: 40-year-old woman post-breast cancer treatment

This patient is a woman with a history of breast cancer treated with Tamoxifen, no current issues, but experiences symptoms similar to other patients. Her stressful lifestyle and recent travel further complicate her differential diagnosis.

• Pulmonary Infection: Post-travel, she may have contracted a respiratory infection, such as influenza or bacterial pneumonia, leading to her symptoms.
• Pulmonary Embolism: Given her stress level, frequent travel, and recent illness, risk factors for hypercoagulability increase suspicion for PE, which can manifest with chest pain and shortness of breath.
• Cardiac Causes, such as Myocardial Ischemia: Her stress-related lifestyle might predispose her to angina or myocardial infarction, especially if she has underlying coronary risk factors.

In conclusion, initial differential diagnoses focus on common and high-risk conditions for each patient. In the subsequent part of this assignment, a comparison will explore whether these initial thoughts align with final diagnoses after further clinical evaluation and research.
