RHIT Systems 3 — Questions and Answers
Question 1: A health system wants to analyze trends across millions of historical patient records without impacting the live EHR's performance. The best solution is to use a:
- Transactional database
- Data warehouse (Correct answer)
- Master Patient Index
- Clinical data repository
Correct answer: Data warehouse
A data warehouse is optimized for large-scale analytical queries on historical data, separate from the operational transactional system.
Question 2: Role-based access control (RBAC) in an EHR system grants permissions based on:
- Individual user identity only
- The user's job function or title (Correct answer)
- The sensitivity of the data requested
- The time of day the system is accessed
Correct answer: The user's job function or title
RBAC assigns system access privileges according to a user's defined role or job function within the organization.
Question 3: In healthcare IT, SOA stands for Service-Oriented Architecture. Its primary advantage for health information systems is:
- Lower hardware costs
- Reusable, loosely coupled services that can be shared across applications (Correct answer)
- Faster data entry by clinical staff
- Elimination of paper records
Correct answer: Reusable, loosely coupled services that can be shared across applications
SOA allows individual services (e.g., patient lookup) to be built once and reused across multiple applications, reducing duplication.
Question 4: Which system generates automated alerts to clinicians when a patient's orders may cause a drug-drug interaction?
- Laboratory Information System
- Pharmacy Information System
- Clinical Decision Support System (Correct answer)
- Document Management System
Correct answer: Clinical Decision Support System
Clinical Decision Support Systems (CDSS) analyze patient data against clinical rules to generate alerts, reminders, and recommendations.
Question 5: A hospital uses a system to assign IDs, merge duplicate records, and maintain a single authoritative list of patients across facilities. This is a:
- Enterprise Master Patient Index (EMPI) (Correct answer)
- Registry system
- Health Information Exchange (HIE)
- Patient portal
Correct answer: Enterprise Master Patient Index (EMPI)
An Enterprise Master Patient Index (EMPI) maintains a unique, accurate patient identity record across multiple facilities within a health system.
Question 6: Which FHIR resource type would be used to represent a patient's documented allergy to penicillin?
- Condition
- AllergyIntolerance (Correct answer)
- MedicationStatement
- Observation
Correct answer: AllergyIntolerance
The FHIR AllergyIntolerance resource is specifically designed to capture a patient's risk of adverse reaction to a substance.
Question 7: Which network topology connects all nodes directly to a central hub or switch, making it easy to add devices but creating a single point of failure?
- Ring topology
- Bus topology
- Star topology (Correct answer)
- Mesh topology
Correct answer: Star topology
In a star topology, all devices connect to a central hub or switch; if the hub fails, all connected nodes lose connectivity.
