Case Study 2: Evaluating Pathological Disruptions in Homeostasis

Clinical Presentation and Initial Assessment

In NSG 5003 Advanced Pathophysiology Week 3 Case Study 2 Questions, students encounter a patient with a constellation of symptoms indicative of systemic dysfunction. A thorough patient history, physical examination, and laboratory workup are essential in differentiating between potential diagnoses. The clinical scenario often involves:

• Multisystem involvement – Patients may present with symptoms affecting the cardiovascular, neurological, renal, or immune systems.
• Complex symptomatology – Overlapping symptoms necessitate a methodical approach to differential diagnosis.
• Laboratory findings interpretation – Key biomarkers provide insights into disease mechanisms and progression.

Understanding the nuances of NSG 5003 Advanced Pathophysiology Week 3 Case Study 2 requires dissecting the interplay between genetic predispositions, inflammatory processes, and cellular responses.

Pathophysiological Mechanisms Explored

1. Inflammation and Immune Dysregulation

   • A hallmark of many chronic and acute conditions, inflammation plays a dual role as both a protective response and a potential driver of disease.
   • The case study examines how cytokine imbalances, leukocyte activity, and immune modulation contribute to disease states.

2. Endocrine System Perturbations

   • Disruptions in hormonal homeostasis can cascade into multisystem disorders.
   • The study delves into mechanisms such as insulin resistance, hypothalamic-pituitary axis dysfunction, and adrenal insufficiencies.

3. Neurovascular Complications

   • Many pathologies involve neurovascular interplay, where compromised blood flow or neural transmission exacerbates disease severity.
   • The relationship between hypertension, ischemia, and neurodegeneration is a focal point.

4. Genetic and Epigenetic Influences

   • Beyond acquired conditions, genetic predispositions significantly shape disease trajectories.
   • Epigenetic modifications, such as DNA methylation and histone modifications, play a role in disease expression.

5. Metabolic and Mitochondrial Dysfunctions

   • Cellular energy production is crucial in maintaining homeostasis, and mitochondrial dysfunction is a key factor in many chronic diseases.
   • The role of oxidative stress and metabolic derangements is explored within the case study context.

Below are sample Questions and Answers:

Week 3 Case Study 2
Mr. Delano comes in to discuss the results of cardiovascular diagnostic tests. He is a 61-
year-old White man with no complaints. Past medical history: left hip osteoarthritis and gout;
Past surgical history: none; Allergies: none known; Medications: allopurinol 100 mg by mouth
once a day; Social history: one to two alcoholic drinks three times a week; smokes one cigar
every other month; exercises for 1 hour six times a week; retired nurse—works per diem at
hospital once a week; Family history; mother, father, and one bother with hypertension; one
brother with dyslipidemia. Physical exam: vital signs – temperature 98.5°F; pulse 60 beats per
minute; respirations 20 per minute; and blood pressure 134/67 mmHg; height 180 cm; weight:
85.5 kg; body mass index 26.3; physical exam unremarkable. See cardiovascular diagnostics
table in the text on page 157.
Which of the cardiovascular diagnostic values demonstrate dyslipidemia and risk for
atherogenesis?
Based on the lipid panel results, Mr. Delano has an elevated total cholesterol level,
decreased high density lipoprotein (HDL) cholesterol, and increased low density lipoprotein
(LDL) cholesterol, indicating that he has dyslipidemia and a higher risk for coronary artery
disease (CAD), hypertension, atherosclerosis, and cerebrovascular accident (CVA) (Dlugasch &
Story, 2019).
Interpret and describe lipoprotein subfractions and apolipoproteins results.
According to Feingold (2026), plasma lipoproteins are distinguished by size, density, and
apolipoproteins, which are delineated by their functions (structural roles, ligand activity,
lipoprotein formation, & activation/inhibition of enzymes) in the metabolism of lipoproteins.
