CRA Health Informatics & Information Management 1 — Questions and Answers
Question 1: What does PACS stand for in radiology informatics?
- Patient Access and Control System
- Picture Archiving and Communication System (Correct answer)
- Primary Archive and Clinical System
- Portable Archiving and Communication Server
Correct answer: Picture Archiving and Communication System
PACS stands for Picture Archiving and Communication System, the technology used to store, retrieve, manage, and distribute medical images electronically.
Question 2: Which international standard is primarily used for storing and transmitting medical imaging data between systems?
- HL7
- ICD-10
- DICOM (Correct answer)
- SNOMED CT
Correct answer: DICOM
DICOM (Digital Imaging and Communications in Medicine) is the international standard specifically designed for medical imaging data storage, transmission, and display.
Question 3: What is the primary purpose of a Radiology Information System (RIS)?
- Generate patient billing codes automatically
- Store medical images in digital format
- Connect hospital departments via electronic messaging
- Manage scheduling, tracking, and reporting of radiology exams (Correct answer)
Correct answer: Manage scheduling, tracking, and reporting of radiology exams
A RIS primarily manages the administrative workflow of a radiology department, including scheduling, patient tracking, exam ordering, and report distribution.
Question 4: What does HL7 stand for in healthcare informatics?
- Health Level Seven (Correct answer)
- Hospital Language System Seven
- Healthcare Laboratory Protocol
- High Level Transfer Seven
Correct answer: Health Level Seven
HL7 stands for Health Level Seven, an international set of standards for the exchange, integration, sharing, and retrieval of electronic health information.
Question 5: Which federal regulation most directly governs the privacy and security of electronic protected health information (ePHI)?
- OSHA 29 CFR 1910
- FDA 21 CFR Part 11
- Joint Commission accreditation standards
- HIPAA Security Rule (Correct answer)
Correct answer: HIPAA Security Rule
The HIPAA Security Rule establishes national standards for protecting electronic protected health information (ePHI), requiring administrative, physical, and technical safeguards.
Question 6: What is the primary function of integrating PACS with a Radiology Information System (RIS)?
- Generate automated billing codes from images
- Manage staff scheduling and payroll functions
- Enable seamless exchange of patient demographics and image data (Correct answer)
- Replace the need for radiologist interpretation
Correct answer: Enable seamless exchange of patient demographics and image data
PACS-RIS integration enables seamless exchange of patient demographics, order information, and imaging data, streamlining radiology workflow and reducing manual data entry.
Question 7: In radiology informatics, what does the term 'worklist' refer to?
- A list of pending equipment maintenance tasks
- A queue of ordered imaging studies awaiting acquisition or interpretation (Correct answer)
- A record of technologist work hours and shifts
- A list of contrast media inventory levels
Correct answer: A queue of ordered imaging studies awaiting acquisition or interpretation
A modality worklist in radiology informatics is the queue of ordered imaging studies that have been scheduled and are awaiting acquisition by technologists or interpretation by radiologists.
