HAC Healthcare Analyst Health Informatics & Technology 1 — Questions and Answers
Question 1: What is the primary purpose of an Electronic Health Record (EHR) system in a clinical setting?
- To digitally store and manage comprehensive patient health information across providers (Correct answer)
- To automate insurance billing only
- To replace verbal communication between clinicians
- To generate administrative reports for regulators
Correct answer: To digitally store and manage comprehensive patient health information across providers
EHRs provide a longitudinal digital record of patient health information accessible to authorized providers to support coordinated care.
Question 2: Which federal law established the framework for EHR adoption incentives and meaningful use requirements?
- Health Information Technology for Economic and Clinical Health (HITECH) Act (Correct answer)
- Health Insurance Portability and Accountability Act (HIPAA)
- Affordable Care Act (ACA)
- Medicare Access and CHIP Reauthorization Act (MACRA)
Correct answer: Health Information Technology for Economic and Clinical Health (HITECH) Act
The HITECH Act of 2009 created Medicare and Medicaid incentive programs to promote meaningful use of certified EHR technology.
Question 3: In health informatics, what does 'interoperability' mean?
- The ability of different health IT systems to exchange and use patient data seamlessly (Correct answer)
- The capacity of a system to operate without downtime
- The compatibility of medical devices with hospital networks
- The standardization of medical billing codes
Correct answer: The ability of different health IT systems to exchange and use patient data seamlessly
Interoperability enables disparate health IT systems and organizations to exchange, interpret, and use shared health data effectively.
Question 4: Which standard messaging protocol is most commonly used for exchanging clinical and administrative data between healthcare systems?
- HL7 (Health Level Seven) (Correct answer)
- DICOM
- ICD-10
- X12 EDI
Correct answer: HL7 (Health Level Seven)
HL7 is the predominant standard for defining the structure and format of messages exchanged between clinical and administrative healthcare systems.
Question 5: What is the role of a 'data dictionary' in a healthcare information system?
- It defines the structure, format, and meaning of each data element in the system (Correct answer)
- It translates clinical notes into billing codes
- It stores patient demographic information
- It catalogs available reporting templates
Correct answer: It defines the structure, format, and meaning of each data element in the system
A data dictionary documents metadata about each field—its name, type, allowable values, and definition—ensuring consistent data interpretation.
Question 6: Which imaging standard governs the storage, transmission, and display of medical images such as X-rays and MRIs?
- DICOM (Digital Imaging and Communications in Medicine) (Correct answer)
- HL7 FHIR
- SNOMED CT
- LOINC
Correct answer: DICOM (Digital Imaging and Communications in Medicine)
DICOM is the international standard for handling, storing, printing, and transmitting medical imaging information across devices and systems.
