University
1. A nurse is explaining the Data-Information-Knowledge-Wisdom (DIKW) framework to a
student. Which of the following best describes the ‘Knowledge’ component of this
framework?
A. Discrete objective facts that have not yet been interpreted.
B. The synthesis of information to identify relationships and patterns.
C. Data that has been processed and organized to provide meaning.
D. The appropriate use of knowledge to manage and solve human problems.
Correct Answer: B
Rationale: Knowledge is characterized by the identification of patterns and relationships
within information. In the DIKW framework, knowledge is the step where information is
synthesized to provide a deeper understanding. This understanding allows for clinical
reasoning and is a precursor to achieving wisdom in practice.
,2. The Informatics Nurse Specialist (INS) is participating in the selection of a new electronic
health record (EHR). Which of the following activities are considered core competencies of
the INS role? (Select all that apply)
A. Designing clinical workflows and system interfaces.
B. Analyzing data to evaluate clinical outcomes.
C. Providing direct bedside care to complex surgical patients.
D. Leading project management for system implementation.
E. Performing complex hardware repairs on server systems.
F. Developing policies related to data privacy and security.
Correct Answer: A,B,D,F
Rationale: The Informatics Nurse Specialist focuses on the intersection of nursing science,
computer science, and information science to manage data and improve outcomes. Core
competencies include workflow design, data analysis, project management, and policy
development. Direct patient care and hardware repair are generally outside the scope of
specialized nursing informatics practice.
3. A hospital utilizes a Clinical Decision Support System (CDSS) to enhance patient safety.
Which feature of a CDSS is designed to alert the nurse to potential medication errors?
A. Computerized Provider Order Entry (CPOE) with drug-drug interaction checks.
B. Automatic pharmacy billing.
, C. A searchable database for hospital policy manuals.
D. The ability to print patient education materials.
Correct Answer: A
Rationale: CDSS components like drug-drug interaction checks provide real-time alerts to
clinicians during the ordering or administration process. This technology is critical for
preventing adverse drug events by cross-referencing patient data with pharmacological
databases. It transforms passive data storage into active clinical guidance at the point of
care.
4. Under the Health Insurance Portability and Accountability Act (HIPAA), which of the
following is considered ‘Protected Health Information’ (PHI)?
A. De-identified data used for a research study.
B. A patient’s social security number and date of birth.
C. Statistical data regarding hospital infection rates without patient names.
D. Anonymous feedback from a hospital satisfaction survey.
Correct Answer: B
Rationale: PHI includes any information that can be used to identify an individual and
relates to their past, present, or future physical or mental health. Items such as SSNs, dates
of birth, and medical record numbers are explicit identifiers under HIPAA. Protecting this
information is a legal and ethical requirement for all healthcare providers and informatics
professionals.
