,A nurse is implementing a clinical decision support system (CDSS) to
reduce medication errors. Which feature best supports this goal?
a) Automated billing processes
b) Real-time allergy alerts during order entry
c) Staff scheduling optimization
d) Patient educational videos delivery
Answer: b) Real-time allergy alerts during order entry
Rationale: Real-time alerts prevent medication errors by notifying
providers of allergy conflicts before administration.
Which data standard is primarily used to ensure interoperability among
electronic health records (EHRs)?
a) ICD-10
b) HL7
c) CPT
d) LOINC
Answer: b) HL7
Rationale: HL7 is a widely adopted standard for exchanging clinical and
administrative data between healthcare systems.
When evaluating an EHR's usability, a nurse should assess all EXCEPT:
a) Interface intuitiveness
b) Speed of data entry
c) Cost of hardware
d) Error message clarity
Answer: c) Cost of hardware
Rationale: Usability focuses on interaction quality, not on hardware cost.
Which of the following best describes a data warehouse in nursing
informatics?
a) A place where paper charts are stored
b) A centralized repository integrating data from multiple sources
c) A software tool for patient scheduling
2
, d) A device used to scan patient IDs
Answer: b) A centralized repository integrating data from multiple
sources
Rationale: Data warehouses aggregate data, supporting analytics and
reporting.
What is the primary benefit of using standardized nursing language such
as NANDA, NIC, and NOC in electronic documentation?
a) Ensures patient data remains confidential
b) Enhances communication and comparability
c) Speeds up transcription time
d) Reduces need for clinical judgement
Answer: b) Enhances communication and comparability
Rationale: Standardized languages improve data consistency and
interoperability across settings.
True/False
A virtual health record (VHR) compiles data from multiple healthcare
providers to create a unified patient history.
Answer: True
Rationale: VHR integrates fragmented data to support continuity of care.
Nursing informatics only involves the use of computer hardware in
clinical settings.
Answer: False
Rationale: Nursing informatics includes software, data management,
workflow analysis, and more.
Biometric authentication is commonly used to enhance EHR security.
Answer: True
Rationale: Biometrics such as fingerprint or iris scan improves identity
verification.
Telehealth platforms cannot provide vital signs monitoring remotely.
