To prepare

• Reflect on the phenomenon of interest and concepts you identified in the Week 2 Discussion. Based on insights you have gained this week, would you like to make any modifications to your phenomenon and/or concepts? If so, you may do so before posting to this Discussion.
• Although you will identify more than one concept for your research, select one primary concept on which to focus for this Discussion. Your concept should be one word or a very short phrase (e.g., “quality of life”).
• Review the literature to see how this concept is defined in various sources. Remember to look at literature across all disciplines in which this concept may be used. Also search for all known definitions of the word in an unabridged dictionary.
• As you do this, consider the following: 
  • Has the concept been developed directly from nursing or health care research or practice, or has it been borrowed or derived from another discipline?
  • To what degree is the concept abstract or concrete?
  • How suitable is this concept for your intended use?
• Formulate a definition of the concept that aligns with your intended research. (Your definition may continue to evolve as you complete your concept analysis for the Assignment introduced this week. In addition, you will likely make adjustments as you proceed through this course and/or later in this PhD program if you continue to address the concept.)

By Day 3 

Post your selected concept and provide a definition of it, as well as context to help your colleagues understand what you are addressing. Summarize at least one article that addresses the concept and discuss how the information presented relates to your own definition of the concept.

D. D. is a 66 year-old female suffering from shortness of breath. She smoked 2 packs a day until she quit 2 years ago. She has a history of bronchiolitis, hyperinflated lungs, pulmonary edema, and syncope. Her primary care practitioner suspects she also has pulmonary hypertension (PH). After examination, D. D. has a PAP of 35mmHg and mild CHF.

Citing scholarly resources!!, answer the following questions: 

1.What is pulmonary hypertension and how could D. D. have developed PH?

2. How does her history fit in with her new diagnosis?

In addition to the two questions above, select Only ONE other question from the list below to complete your discussion post. Be sure to cite the sources of your information and clearly identify which supplemental question you chose to answer!!!

1. How many patients are suffering from COPD in the United States? Do COPD sufferers die of respiratory causes or other causes? (Be sure to cite the data.)

2.What two separate diseases are the main COPD diseases? Give background on each disease.

3.How does COPD correlate with left ventricular pressure and primary heart failure?

4.What are the three types of bronchodilators, and how do they function to alleviate the symptoms of COPD? What are other possible treatments for COPD? 

5.Through which mechanism does bronchiolitis cause destruction of alveoli? Is emphysema genetic? Can environmental factors increase the risk of emphysema? Why or why not? 

6. Is lung transplantation a solution for emphysema? Can new technology be useful in the treatment of emphysema? Why or why not?
