QUESTION AND CORRECT ANSWER WITH
EXPLANATION WEST COAST UNIVERSITY
1. A hospital experiences inconsistencies between medication orders
in the Electronic Health Record (EHR) and pharmacy system. Which
interoperability issue is MOST likely responsible?
A. Foundational interoperability failure
B. Structural interoperability mismatch
C. Semantic interoperability inconsistency
D. Network connectivity issue
Correct Answer: C
Rationale: Semantic interoperability ensures that the meaning of
exchanged data is preserved. Inconsistencies in medication orders often
arise when systems interpret data differently despite successful
transmission.
2. A Health IT specialist is designing a database to minimize
redundancy while maintaining performance. Which technique is
MOST appropriate?
A. Denormalization
B. Data replication
C. Normalization up to third normal form (3NF)
D. Data compression
Correct Answer: C
Rationale: Normalization to 3NF reduces redundancy and ensures data
integrity while maintaining efficient querying.
3. A clinician overrides a high-severity drug interaction alert multiple
times. Which system improvement would BEST address this issue?
A. Remove all alerts
B. Implement alert prioritization and tiering
,C. Increase alert frequency
D. Disable clinical decision support
Correct Answer: B
Rationale: Tiering alerts based on severity reduces alert fatigue and
ensures critical alerts are taken seriously.
4. A hospital integrates external lab systems using FHIR. What is the
PRIMARY advantage over traditional HL7 v2 messaging?
A. Reduced data accuracy
B. Real-time API-based data exchange
C. Increased system complexity only
D. Elimination of data standards
Correct Answer: B
Rationale: FHIR uses modern web technologies (APIs) to enable real-
time, flexible data exchange compared to traditional message-based
systems.
5. A ransomware attack encrypts hospital data. Which control would
have MOST reduced operational impact?
A. Strong passwords
B. Regular offline backups
C. Firewall configuration
D. Data normalization
Correct Answer: B
Rationale: Offline backups allow restoration of data without relying on
compromised systems, minimizing downtime.
6. A Health IT specialist is analyzing a spike in unauthorized access
attempts. Which log source is MOST valuable?
A. Application logs only
B. Network firewall logs
, C. Audit logs and authentication logs
D. Backup logs
Correct Answer: C
Rationale: Authentication and audit logs provide detailed records of
login attempts and user activities, critical for security analysis.
7. Which of the following BEST ensures referential integrity in a
relational database?
A. Indexes
B. Foreign keys
C. Data compression
D. Views
Correct Answer: B
Rationale: Foreign keys enforce relationships between tables, ensuring
data consistency.
8. A hospital wants to support advanced analytics across multiple
data sources. Which architecture is MOST appropriate?
A. Standalone databases
B. Clinical data warehouse
C. Flat file systems
D. Manual records
Correct Answer: B
Rationale: Data warehouses consolidate data from multiple systems for
analytics and reporting.
9. A clinician enters incorrect medication dosage due to poor
interface design. Which principle was violated?
A. Data governance
B. Human-computer interaction (HCI) usability
C. Data encryption
D. Data backup
