RHIT Systems 5 — Questions and Answers
Question 1: A project manager uses a Gantt chart during an EHR implementation. This tool primarily shows:
- System architecture and data flow
- Task schedules, durations, and dependencies over time (Correct answer)
- Budget allocation per department
- Staff competency assessment results
Correct answer: Task schedules, durations, and dependencies over time
A Gantt chart is a bar chart that displays project tasks along a timeline, showing start/end dates and task dependencies.
Question 2: In healthcare information systems, 'throughput' refers to:
- The number of authorized users on the system
- The volume of transactions or data a system can process in a given time period (Correct answer)
- The physical storage capacity of a server
- The speed of data entry by clinical staff
Correct answer: The volume of transactions or data a system can process in a given time period
Throughput measures how many transactions, messages, or operations a system can handle per unit of time.
Question 3: Which type of system test verifies that new or modified software functions correctly after updates without breaking existing functionality?
- User acceptance testing (UAT)
- Regression testing (Correct answer)
- Integration testing
- Stress testing
Correct answer: Regression testing
Regression testing re-runs previously passing tests after changes to confirm that existing features still work correctly.
Question 4: A clinical information system automatically flags a lab result that falls outside the reference range and notifies the ordering physician. This is an example of:
- Passive data collection
- Clinical decision support with alerting (Correct answer)
- Automated billing workflow
- Population health surveillance
Correct answer: Clinical decision support with alerting
Clinical decision support systems generate alerts when clinical data (like lab results) triggers defined rule thresholds.
Question 5: Which technical standard defines the format for transmitting medical images between imaging devices and PACS systems?
- HL7 v2.x
- DICOM (Correct answer)
- ICD-10-CM
- X12 EDI
Correct answer: DICOM
DICOM (Digital Imaging and Communications in Medicine) is the international standard for medical image formatting and transmission.
Question 6: A hospital's disaster recovery plan includes a secondary data center that can assume operations within four hours of a primary site failure. The four-hour target is the system's:
- Recovery Point Objective (RPO)
- Recovery Time Objective (RTO) (Correct answer)
- Mean Time Between Failures (MTBF)
- Service Level Agreement (SLA)
Correct answer: Recovery Time Objective (RTO)
Recovery Time Objective (RTO) defines the maximum acceptable duration to restore a system to operation after a disruption.
Question 7: In evaluating a new health information system, the measure that compares total expected costs against total expected benefits over a defined period is called a:
- Feasibility study
- Cost-benefit analysis (Correct answer)
- Needs assessment
- Gap analysis
Correct answer: Cost-benefit analysis
A cost-benefit analysis quantifies and compares the total costs and anticipated benefits of a system investment to determine financial viability.
