Final answer:
To build the body of nursing knowledge, a study should be based on published research findings and fit logically with what is already known. It should aim to produce results that are applicable to a variety of situations.
Step-by-step explanation:
To build the body of knowledge of nursing, a problem amenable to study should be based on published research findings and fit logically with what is already known. This ensures that the study contributes to existing knowledge and advances the field. A problem that is an original area of study never researched previously may also be acceptable, but it is not a requirement. The goal is to produce results that are applicable to a variety of situations, which helps in developing generalizable knowledge.
