Foundations of Nursing Informatics
What the domain covers
The ANA defines nursing informatics as the specialty that integrates nursing science with multiple information and analytical sciences to identify, define, manage, and communicate data, information, knowledge, and wisdom in nursing practice. Questions here test whether you can place a concept in the right category, not merely recognize a definition.
DIKW. Data are discrete, uninterpreted facts (a single value of 38.9 C). Information is data organized with context and meaning (a temperature trend over twelve hours). Knowledge is synthesized information with relationships and interpretation (a pattern consistent with developing sepsis). Wisdom is the appropriate use of knowledge in a specific human situation (escalating to the rapid response team). Exam traps ask you to classify an example; look for context and interpretation rather than the number itself.
Standardized languages. NANDA-I names nursing diagnoses, NIC names interventions, NOC names outcomes, and together they support the nursing process. SNOMED CT is a comprehensive clinical reference terminology used to map concepts across systems. LOINC covers laboratory and clinical observations. The Omaha System, Clinical Care Classification, ICNP, and the Perioperative Nursing Data Set address community, general classification, international, and specialty needs. A recurring trap is attributing laboratory coding to SNOMED or diagnoses to LOINC.
Roles and competencies. The informatics nurse is a generalist prepared at or below the baccalaureate level who applies informatics in practice; the informatics nurse specialist is graduate-prepared and leads design, research, and evaluation. Both need computer literacy, information literacy, and informatics literacy, and both progress along a novice-to-expert continuum.
Rule of thumb: before answering, ask whether the question is about a fact, a pattern, a decision, or a role. That single step usually eliminates three of four options.
