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.
