Define research.

• A. Random exploration to gather data
• B. An unstructured inquiry
• C. Systematic and organized investigation to find a solution or develop new practices
• D. Opinion-based inquiry

Answer: (C)

Research is a systematic and organized investigation to answer questions or develop new practices. It follows a planned approach with defined methods to collect and analyze data, so findings are reliable and can guide decisions or advance knowledge. In nursing, this means designing studies, reviewing existing evidence, upholding ethical standards, and aiming to improve patient care and outcomes. Random exploration lacks structure, unstructured inquiry misses a rigorous method, and opinion-based inquiry relies on beliefs rather than evidence, whereas research builds knowledge through a repeatable process and careful analysis.
