Answer to Question 1
ANS: 3
In experimental research, the investigator controls the study variable (use of humor) and ran-domly assigns subjects to different conditions (those who receive humor as an intervention, and those who do not).
The effect of therapeutic touch on a geriatric client with Alzheimer's disease lends itself to the nursing process as a nursing intervention to perhaps assist a client in meeting a goal of preventing social isolation. To use the experimental research process, there would have to be other clients involved (i.e., a group of clients with Alzheimer's disease who receive therapeutic touch, and a group of clients with Alzheimer's disease who do not receive therapeutic touch) to determine whether or not therapeutic touch had any effect.
Prioritizing nursing diagnoses for client care is an example of using the nursing process.
Determining the blood pressure patterns of a client who recently had a cerebrovascular accident is a part of the assessment phase of the nursing process. In contrast to an experimental research study, no variable is being controlled by the nurse.
Answer to Question 2
ANS: 3
Correlational research explores the interrelationships among variables of interest (such as factors affecting client comfort) without any active intervention by the researcher.
Historical research is designed to establish facts and relationships concerning past events. It would not use prospective groups of clients.
Evaluation research tests how well a program, practice, or policy is working.
In experimental research, the investigator controls the study variable and randomly assigns sub-jects to different conditions.
