In nursing informatics, which term refers to encoding knowledge so machines can perform reasoning?

• A. Artificial Intelligence
• B. Knowledge Query
• C. Neural Computing
• D. Knowledge Representation

Answer: (D)

Knowledge representation is the process of encoding clinical knowledge into formal structures that a computer can manipulate to reason. In nursing informatics, this means turning guidelines, relationships, and rules into representations like ontologies, rule-based IF-THEN constructs, semantic networks, or frames so a decision support system can infer conclusions and suggest actions from patient data. For example, encoding a rule such as “if the patient has a penicillin allergy, flag penicillin orders for clinician review” allows the system to reason about safety and trigger appropriate alerts. Artificial intelligence is a broad field that includes knowledge representation but isn’t the specific act of encoding knowledge for reasoning. Neural computing relies on learning from data rather than explicit knowledge encoding. Knowledge query describes retrieving information rather than structuring knowledge for reasoning. Therefore, the best term is knowledge representation.
