Which of the following best defines information science?

• A. Designing and implementing data capture systems
• B. Obtaining, gathering, organizing, manipulating, managing, storing, retrieving, recapturing, disposing of, distributing or broadcasting information
• C. Ensuring clinical workflows are efficient
• D. Securing hardware and networks

Answer: (B)

Information science focuses on how information is captured, organized, managed, stored, retrieved, shared, and ultimately disposed of across its entire lifecycle. The best definition here lists the full sequence—obtaining, gathering, organizing, manipulating, managing, storing, retrieving, recapturing, disposing of, distributing or broadcasting information—which emphasizes turning data into usable information and making it accessible when and where it’s needed. The other options describe more narrow areas: designing data capture systems is about creating data collection methods; ensuring clinical workflows are efficient targets process optimization rather than the overall information management lifecycle; securing hardware and networks deals with security and infrastructure, not the information-handling scope. In nursing informatics, mastering this lifecycle underpins how data become actionable information for evidence-based practice and decision making.
