1. What is the purpose of the research study?
The purpose of the research study is to determine the effects of cardiac rehabilitation and exercise training in obese coronary patients.
2. Are the problem & purpose of the study clearly & concisely expressed?
Yes, the studies purpose or objective as the article calls it is the first statement made in the abstract.
3. Does the purpose identify the variables, population, & setting of the study?
The purpose statement does identify the population as obese coronary patients; the setting is two large teaching institutions and the variables are obese coronary patients versus non-obese coronary patients involved in cardiac rehabilitation and exercise training.
4. What is the significance of the problem for generating nursing knowledge as identified by the investigator?
It was determined cardiac rehabilitation significantly reduced coronary risk factors in obese patients. It was also determined that coronary risk factors were even further reduced in non-obese patients following cardiac rehabilitation. The point made was that by specifically targeting obese coronary patients for cardiac rehabilitation, would yield greater exercise capacity, and improved lipid values.
5. Discuss the feasibility issues of studying this problem.
I think this study would be easy to accomplish. I believe that most of the activity already takes place in facilities with cardiac rehabilitation programs. It would be a matter of collecting all the data and insuring that lab values and exercise tolerance data be recorded and maintained.
1. What are the research variables in the study? Identify independent and dependent where appropriate.
The independent research variable would be the coronary patients, obese and non-obese. The dependant variable would be the data collected, such as exercise tolerance, lab values of lipid profiles and body mass index.
2. How are the variables conceptually and opera...
