Milestone One: Selection of a Peripheral Artery Disease Case for Pathophysiological Analysis
The Selected Case
The selected case is a 66-year-old man, a retired bus mechanic, who describes a cramping pain in his right calf that begins after walking about two blocks and eases within a few minutes of standing still. The pain has gradually shortened the distance he can walk over the past year, and he has stopped his daily walks with his wife. He has type 2 diabetes diagnosed 12 years ago, hypertension and high cholesterol. He smoked about a pack a day from age 18 until he quit at 60.
On examination, the right foot is cooler than the left, with thin shiny skin and little hair on the lower leg. The dorsalis pedis and posterior tibial pulses are faint on the right and normal on the left. His ankle-brachial index is 0.62 on the right and 0.94 on the left. His most recent hemoglobin A1c was 8.1 percent and his LDL cholesterol 132 mg/dL. He has no open wounds and no pain at rest.
Rationale for Selecting This Case
Three reasons make this case a strong choice for the final analysis. First, the mechanism can be traced from the cell to the symptom in a clear chain. Atherosclerosis narrows the arteries of the leg, blood flow cannot rise to meet the demands of working muscle, and the resulting ischemia produces pain that stops when demand falls. That chain allows the analysis to connect cellular events such as endothelial dysfunction and plaque formation to what the patient feels and what the examination shows.
Second, the case has multiple interacting risk factors. Smoking history, diabetes, hypertension and high cholesterol each contribute to atherosclerosis through different mechanisms, which gives the analysis room to explain how risk factors combine. Third, the condition is common and often missed. Peripheral artery disease affects a large number of older adults, and many have atypical symptoms or none at all, so it is frequently underdiagnosed (Criqui & Aboyans, 2015). A nurse who understands the mechanism is better able to recognize early signs, such as a shortening walking distance, before the disease progresses to rest pain or tissue loss.
An Early Outline of the Mechanism
Peripheral artery disease in this patient is almost certainly caused by atherosclerosis. The process begins when the endothelium, the inner lining of the artery, is injured by factors such as tobacco toxins, high glucose, high blood pressure and oxidized LDL cholesterol. Injured endothelium becomes more permeable and more adhesive, allowing lipids and inflammatory cells to enter the vessel wall and form a plaque that gradually narrows the lumen (Rogers, 2023).
At rest, a narrowed artery may still deliver enough blood. During walking, the calf muscles need much more oxygen, but the stenosis limits how much flow can increase. The muscle shifts toward anaerobic metabolism, and the accumulating metabolites stimulate pain receptors, producing claudication. When the patient stops walking, demand falls and the pain resolves. The ankle-brachial index of 0.62 reflects the pressure drop across the narrowed segment, and the cool skin, hair loss and weak pulses reflect chronically reduced perfusion. These points will be explained in detail in the next milestone.
Risk Factors at a Glance
Each of the patient's four major risk factors will need its own mechanism in the final analysis, and a brief preview shows why they make the case rich. Tobacco smoke delivers oxidants and other toxins that injure the endothelium directly, increase platelet activation and promote inflammation in the vessel wall. Smoking is among the strongest risk factors for peripheral artery disease in particular, and his 42 years of smoking remain relevant even six years after quitting. Diabetes damages vessels through chronically high glucose, which produces advanced glycation end products and oxidative stress, and it is associated with disease in the smaller arteries below the knee.
Hypertension adds mechanical stress to the arterial wall, especially at branch points where flow is turbulent, and high LDL cholesterol supplies the lipid that becomes oxidized and taken up into plaque. Because these factors act on the same endothelium through different pathways, their effects compound. The analysis will explain why a patient with all four has a much higher risk than the sum of each alone would suggest, and why controlling every one of them matters for both the leg and the heart.
Questions for the Analysis
The later milestones will address four questions. How does each of the patient's risk factors, smoking, diabetes, hypertension and dyslipidemia, damage the arterial wall, and why do they add together rather than act alone? Why does the pain appear at a predictable distance and vanish with rest, and what would it mean if it began to occur at rest? What do the ankle-brachial index and the physical findings measure, and how do they relate to the degree of narrowing? Finally, how do the recommended treatments, including supervised exercise, smoking abstinence, cholesterol lowering and antiplatelet therapy, act on the mechanism?
Current guidance on lower extremity peripheral artery disease will be used to frame diagnosis and treatment, since it emphasizes both relief of walking impairment and prevention of heart attack, stroke and limb loss in people with the disease (Gornik et al., 2024).
Why the Case Matters for Nursing
Nurses in primary care, home health and hospital settings often see patients with peripheral artery disease for other reasons. Recognizing the pattern of claudication, checking pedal pulses, and noticing skin changes can lead to earlier diagnosis. Once the disease is known, nurses teach foot care, which is especially important for a patient with diabetes, support smoking abstinence and encourage structured walking, which improves walking distance by training the muscles and circulation to work within the limits of the narrowed arteries. Understanding the mechanism allows the nurse to explain to this patient why walking into mild pain, then resting, is part of treatment rather than a sign of harm.
Plan for the Project
Milestone Two will develop the pathophysiology section in full, explaining endothelial injury, plaque formation and the physiology of exercise-induced ischemia, and linking each finding in the case to its mechanism. The final case analysis will add risk factors, manifestations, diagnostic findings and treatment, and will close with nursing implications such as foot inspection, exercise teaching and recognition of warning signs of critical limb ischemia. Sources will include a pathophysiology text, the current guideline and review articles on the epidemiology and mechanism of the disease.

How this NUR 315 Module 3 example is structured
Milestone One has to convince the instructor that the chosen case is rich enough for a full pathophysiology analysis, so the paper is organized around that argument. The case is summarized first, with the findings that will need explaining. A rationale section gives three reasons for the choice. A short overview of the mechanism shows that the student already sees the chain from atherosclerosis to ischemic muscle pain, without trying to finish the analysis early. Risk factors and manifestations are listed as questions for later work, and the final section maps what Milestone Two and the final case analysis will cover.

NUR 315 Module 3 questions, answered
What does NUR 315 Module 3 Milestone One ask for?
In sections that build a case analysis across the term, the first milestone commonly asks students to select a case or disease, summarize the patient, and explain why the case is suitable, often with an early outline of the pathophysiology. The final project then analyzes the case in depth. Check your classroom guidelines for required elements.
How do I choose a good case for a pathophysiology analysis?
Choose a condition with a clear mechanism, several measurable findings that the mechanism explains, and meaningful risk factors. Cases where you can connect cell-level events to symptoms, tests and treatment give you the most to analyze. Very rare diseases can be hard to support with sources.
How much pathophysiology belongs in Milestone One?
Enough to show you understand the main mechanism and have a plan, not the full analysis. A paragraph or two outlining the chain from cause to symptoms, with the questions you intend to answer later, is usually appropriate. Save detailed explanations for the later milestone and the final project.
