CASE STUDY ANALYSIS

understanding of the respiratory system is a critically important component of disease diagnosis and treatment. This importance is magnified by the fact that oftentimes, the respiratory system works closely with the cardiovascular system. A variety of factors and circumstances that impact the emergence and severity of issues in one system can have a role in the performance of the other.

Effective disease analysis often requires an understanding that goes beyond these systems and their capacity to work together. The impact of patient characteristics, as well as racial and ethnic variables, can also have an important impact.

An understanding of the symptoms of alterations in the respiratory system is a critical step in diagnosis and treatment of many diseases. For APRNs, this understanding can also help educate patients and guide them through their treatment plans.

In this Assignment, you examine a case study and analyze the signs and symptoms presented. You identify the elements that may be factors in the diagnosis, and you explain the implications to patient health.

To prepare:

By Day 1 of this week, you will be assigned to a specific case study scenario for this Case Study Assignment. Please see the “Announcements” section of the classroom for your assignment from your Instructor.

The Assignment

In 2 pages, you will answer the questions provided following the case scenario. You must use current evidence-based resources to support your answers. Follow APA guidelines. Follow the grading rubric.

THE CASE SCENARIO

A 62-year-old male, former smoker with a 40-pack-year history, presents to the clinic with worsening shortness of breath over the past year. He reports a chronic productive cough, fatigue, and occasional wheezing. He finds it difficult to walk up a flight of stairs without stopping to catch his breath. The patient also mentions that he gets frequent respiratory infections, and the last one led to a three-day hospital stay. Physical examination reveals a barrel-shaped chest, use of accessory muscles for breathing, and decreased breath sounds with wheezes upon auscultation. A chest X-ray shows hyperinflation of the lungs, and spirometry confirms a decreased FEV1/FVC ratio, consistent with COPD.

In 2 pages, answer the questions below in detail. You must use current evidence-based resources to support your answers. Follow APA guidelines. Follow the grading rubric.

1. What factors in the patient’s history and lifestyle could have contributed to the development of COPD? What about occupational hazards – what would be some components that could cause COPD in the work environment?
2. How does smoking lead to the changes seen in the lungs, such as hyperinflation and the barrel-shaped chest?
3. What physiological mechanisms are responsible for the patient’s chronic productive cough?
4. How does alveolar destruction impact gas exchange and contribute to the patient’s symptoms of fatigue and breathlessness?
5. Pathophysiological – why might this patient be more susceptible to frequent respiratory infections?
