Pure (basic) research is best described as:

• A. Generating new knowledge to test theories
• B. Solving immediate clinical problems
• C. Evaluating a treatment in patients
• D. Describing patient experiences only

Answer: (A)

Pure or basic research centers on expanding understanding by generating new knowledge and testing theoretical ideas, often without an immediate aim to solve a practical problem. It seeks to build or refine theories about how things work, which then can inform future applications in practice. In nursing science, this might involve exploring fundamental mechanisms behind health behaviors or biological processes to strengthen the theoretical foundation that guides later research and practice.

That’s why the best description is generating new knowledge to test theories. The other descriptions align more with applied or clinical research: solving immediate clinical problems focuses on practical application, evaluating a treatment in patients is about testing interventions in real people, and describing patient experiences emphasizes descriptive or qualitative inquiry rather than theory testing.
