1. A nursing informatics specialist is describing the DIKW hierarchy to a group of new nurse
researchers. Which of the following examples best represents the ‘Knowledge’ stage of the
DIKW framework?
A. The recognition that a blood pressure of 160/90 mmHg is high for a patient with no
history of hypertension.
B. A list of vital signs including a blood pressure reading of 160/90 mmHg.
C. Synthesizing clinical guidelines to create a personalized treatment plan for hypertensive
patients.
D. Collecting the raw number 160 from a digital monitor.
Correct Answer: A
Explanation: Knowledge is the synthesis of information to identify relationships and
provide meaning to data. In this scenario, recognizing that a specific blood pressure
reading is abnormal for a specific patient context moves beyond simple data or
information. This transition involves applying clinical understanding to the information
gathered, which is a core component of nursing informatics practice.
,2. According to the Health Insurance Portability and Accountability Act (HIPAA) Security Rule,
which of the following are considered administrative safeguards? (Select All That Apply)
A. Security management process
B. Workforce security and training
C. Encryption and decryption of data
D. Information access management
E. Automatic log-off on terminals
F. Evaluation of security policies
Correct Answer: A, B, D, F
Explanation: Administrative safeguards involve the policies and procedures designed to
manage the selection, development, implementation, and maintenance of security
measures. Security management, workforce training, access management, and periodic
evaluations are all administrative in nature. Technical safeguards, such as encryption and
automatic log-offs, represent different categories within the HIPAA Security Rule
framework.
3. A hospital is implementing a new Clinical Decision Support System (CDSS). The informatics
nurse explains that a ‘knowledge base’ in a CDSS is typically composed of which elements?
A. The inference engine and user interface.
B. Patient-specific data such as lab results and current medications.
,C. Compiled clinical guidelines, research evidence, and expert consensus.
D. The hardware infrastructure and cloud storage components.
Correct Answer: C
Explanation: The knowledge base is the component of a CDSS that stores the information
used to make decisions, such as rules and associations. It differs from the patient data,
which is specific to an individual, and the inference engine, which applies the knowledge to
that data. A robust knowledge base is essential for providing evidence-based
recommendations at the point of care.
4. During the ‘Analysis’ phase of the System Development Life Cycle (SDLC), what is the
primary goal of the project team?
A. Determining the technical requirements and user needs for the system.
B. Writing the actual code for the software application.
C. Installing the hardware in the clinical units.
D. Conducting a post-implementation review to assess ROI.
Correct Answer: A
Explanation: The analysis phase focuses on understanding the problems in the current
workflow and defining what the new system must do to solve them. It involves gathering
requirements from stakeholders to ensure the final product meets clinical and
administrative needs. This phase is critical because errors in requirement gathering can
lead to system failure during later stages of the life cycle.
, 5. Which standardized nursing terminology is specifically designed to document the nursing
process across all settings and is recognized by the American Nurses Association (ANA)?
A. ICD-10
B. NANDA-I
C. SNOMED-CT
D. LOINC
Correct Answer: B
Explanation: NANDA-I provides a standardized language for nursing diagnoses, which is a
fundamental part of the nursing process. While SNOMED-CT is a broad clinical terminology,
NANDA-I, along with NIC and NOC, focuses specifically on the nursing domain. Utilizing
these terminologies ensures that nursing care is visible and quantifiable within the
electronic health record.
6. What is the primary difference between an Electronic Medical Record (EMR) and an
Electronic Health Record (EHR)?
A. An EMR is restricted to a single provider’s office, while an EHR is designed to be shared
across multiple organizations.
B. An EMR contains more comprehensive historical data than an EHR.
C. EHRs are only used by hospitals, whereas EMRs are used by specialists.
D. There is no difference; the terms are used interchangeably in informatics.
