NSG 5140 WEEK 3 FINAL EXAM -
HEALTHCARE INFORMATICS
1. Which level of interoperability refers to the ability of two or more systems to exchange
information so that the receiving system can interpret the data correctly?
A. Foundational Interoperability
B. Semantic Interoperability
C. Structural Interoperability
D. Organizational Interoperability
Answer: B
Conceptual Explanation: Semantic interoperability ensures that the content of the data is
understood by both the sender and the receiver, allowing for automated processing and
decision support.
2. In the DIKW hierarchy of nursing informatics, which stage represents the application of
data and information to answer ‘how’ questions?
A. Data
B. Information
,C. Wisdom
D. Knowledge
Answer: D
Conceptual Explanation: Knowledge is derived from the synthesis of information to
identify relationships and answer ‘how’ questions in clinical practice.
3. Which terminology is specifically designed to provide a common language for clinical
laboratory test results?
A. SNOMED-CT
B. LOINC
C. ICD-10
D. RxNorm
Answer: B
Conceptual Explanation: LOINC (Logical Observation Identifiers Names and Codes) is the
global standard for identifying health measurements, observations, and documents,
specifically lab tests.
4. What is the primary purpose of a Clinical Decision Support System (CDSS)?
A. To provide clinicians with person-specific, filtered information to enhance health and
healthcare
B. To automate billing and insurance claims processing
, C. To replace clinical judgment during emergency procedures
D. To store long-term electronic health records for research
Answer: A
Conceptual Explanation: CDSS tools are designed to assist clinicians by providing relevant
information at the point of care to improve decision-making and patient outcomes.
5. Under the HIPAA Security Rule, which of the following is considered a ‘Technical
Safeguard’?
A. Encryption and Decryption
B. Workforce Security and Training
C. Facility Access Controls
D. Risk Analysis
Answer: A
Conceptual Explanation: Technical safeguards are the technology and policy and
procedures for its use that protect electronic protected health information (ePHI) and
control access to it, including encryption.
6. Which framework is used to evaluate the usability of a health information system by
identifying specific interface design flaws?
A. Cognitive Walkthrough
B. Heuristic Evaluation
