, I. Multiple Choice Questions (10 Questions)
1. A hospital is implementing an integrated electronic health record
(EHR) system that must communicate with various external systems.
Which standard is most suited for enabling modern, web-friendly data
exchange?
A. HL7 Version 2
B. HL7 Version 3
C. FHIR
D. CDA
ANS: C. FHIR
Rationale: FHIR (Fast Healthcare Interoperability Resources) uses
modern web technologies (such as RESTful APIs and JSON/XML) and is
designed for ease of implementation and broad interoperability among
systems.
2. A clinical decision support system (CDSS) embedded in an EHR is
generating frequent non-specific alerts. Which strategy is most effective
in reducing alert fatigue among clinicians?
A. Increasing the number of alerts
B. Implementing context-sensitive alerts
C. Using a single global alert for all errors
D. Limiting the CDSS to medication alerts only
ANS: B. Implementing context-sensitive alerts
Rationale: Context-sensitive alerts take into account patient-specific
variables; they are tailored to the clinical situation, thereby reducing
nonessential interruptions and alert fatigue.
3. During the design of a nursing informatics application, which user
interface feature is most important for ensuring efficient use by clinical
staff?
A. Advanced 3D graphics

, B. Intuitive navigation
C. Customizable sounds and animations
D. Complex menu structures
ANS: B. Intuitive navigation
Rationale: A user-friendly, intuitive interface minimizes training needs
and reduces errors, allowing clinicians to focus on patient care rather
than struggling with software.
4. A hospital deploys a bar-code medication administration system
integrated with its EHR. What is the primary benefit of this integration?
A. Improved staff satisfaction through technology
B. Reduction in medication administration errors
C. Enhanced patient engagement in care
D. Lower operational costs for the pharmacy
ANS: B. Reduction in medication administration errors
Rationale: The integration of bar-code scanning with EHR verifies
patient identity and medication data, dramatically decreasing the
likelihood of administration errors.
5. To protect patient data stored in an EHR, which measure is most
critical to implement?
A. A blockchain ledger
B. Robust encryption protocols
C. Sole reliance on physical access controls
D. Frequent system reboots
ANS: B. Robust encryption protocols
Rationale: Encryption renders data unreadable to unauthorized
parties during both storage and transmission, thereby ensuring
confidentiality and integrity beyond what physical measures alone can
achieve.
6. A nurse informaticist is analyzing large volumes of clinical data from
multiple sources. What is the primary purpose of employing data mining
techniques in this context?
A. To optimize network connectivity
