A healthcare organization implements a Clinical Decision Support System
(CDSS) that alerts nurses of potential drug interactions. What is the
primary role of this system?
A) Document patient outcomes
B) Support clinical decision-making
C) Automate medication dispensing
D) Schedule nurse shifts
Answer: B
Rationale: CDSS are designed to support clinical decision-making by
providing evidence-based alerts and recommendations, such as drug
interaction warnings.
Which of the following best describes the HL7 standard in nursing
informatics?
A) A hardware protocol for medical devices
B) A messaging standard for electronic health information exchange
C) A security framework for patient data encryption
D) A workflow model for nurse staffing
Answer: B
Rationale: HL7 (Health Level Seven) standards define the protocols for
exchanging clinical and administrative data between healthcare software
systems.
What is the most important consideration when designing an Electronic
Health Record (EHR) interface for nursing documentation?
A) The color scheme of the interface
B) Ease of data entry and workflow integration
C) Compatibility with billing software
D) Ability to play multimedia
Answer: B
2
, Rationale: Ease of data entry and integration with nursing workflow
optimizes efficiency and data accuracy.
Nurses use standardized terminologies such as SNOMED CT primarily to:
A) Receive reimbursement faster
B) Ensure consistent and interoperable documentation
C) Enhance graphic design of records
D) Increase patient privacy safeguards
Answer: B
Rationale: Standardized terminologies promote interoperability and
consistent clinical documentation across systems.
What type of data model is most commonly used in nursing informatics
to represent patient care processes?
A) Relational database model
B) Object-oriented data model
C) Entity-relationship model
D) Semantic data model
Answer: C
Rationale: Entity-relationship models are widely used to represent
complex relationships between patient data elements.
To ensure HIPAA compliance in an EHR system, which feature is
essential?
A) Color-coded alerts
B) Role-based access control
C) Automated patient scheduling
D) Integrated billing functions
Answer: B
Rationale: Role-based access control restricts data access based on user
roles, safeguarding patient privacy as required by HIPAA.
In analyzing nursing workflows, what is a key method used to identify
inefficiencies related to informatics systems?
