RHIT Systems 2 — Questions and Answers
Question 1: Which system architecture model places application processing on a central server while users interact via thin clients or terminals?
- Client-server architecture
- Centralized host-based architecture (Correct answer)
- Peer-to-peer architecture
- Cloud-distributed architecture
Correct answer: Centralized host-based architecture
Centralized host-based architecture processes all applications on a central host, with terminals serving only as input/output devices.
Question 2: In a hospital EHR system, which database concept ensures that a patient's address update in one module automatically reflects across all modules?
- Data replication
- Data redundancy
- Data integration (Correct answer)
- Data normalization
Correct answer: Data integration
Data integration ensures that updates to shared data propagate consistently across all connected modules and systems.
Question 3: A health information system's ability to exchange and use information with other systems is best described as:
- Scalability
- Interoperability (Correct answer)
- Redundancy
- Modularity
Correct answer: Interoperability
Interoperability is the capacity of different systems to exchange, interpret, and use shared health information effectively.
Question 4: Which HL7 standard uses a document-centric XML-based approach for clinical document exchange?
- HL7 v2.x
- HL7 FHIR
- HL7 CDA (Correct answer)
- HL7 v3 RIM
Correct answer: HL7 CDA
HL7 Clinical Document Architecture (CDA) is an XML-based markup standard for encoding clinical documents for exchange.
Question 5: A radiology department uses a system to manage imaging workflows, store images, and distribute them to clinicians. This system is called a:
- Laboratory Information System (LIS)
- Picture Archiving and Communication System (PACS) (Correct answer)
- Clinical Decision Support System (CDSS)
- Master Patient Index (MPI)
Correct answer: Picture Archiving and Communication System (PACS)
PACS (Picture Archiving and Communication System) is specifically designed to store, retrieve, manage, and distribute medical images.
Question 6: When implementing a new EHR, the team creates a parallel environment identical to production to test upgrades without affecting live operations. This is called a:
- Sandbox environment
- Production mirror
- Test/staging environment (Correct answer)
- Disaster recovery environment
Correct answer: Test/staging environment
A test or staging environment replicates the production setup and is used to safely validate changes before live deployment.
Question 7: Which system component is responsible for translating messages between systems that use different data formats or communication protocols?
- Firewall
- Interface engine (Correct answer)
- Application server
- Data warehouse
Correct answer: Interface engine
An interface engine (also called an integration engine) translates and routes messages between disparate health information systems.
