SECTION 1: Health Informatics Foundations (10 questions)
Q1: What is the primary purpose of the electronic health record (EHR)?
A. To serve as a legal document for billing purposes
B. To provide a complete, accurate, and accessible patient health record [CORRECT]
C. To replace all paper documentation
D. To store patient data for research only
Correct Answer: B
Rationale: Correct because the EHR serves as a comprehensive, longitudinal record
of patient health information that supports clinical decision-making, care
coordination, and quality improvement across the care continuum.
Q2: The Institute of Medicine (IOM) identified which core function as essential for
EHR systems?
A. Health information and data capture only
B. Order management only
C. Administrative processes only
D. Health information capture, order management, clinical decision support, and
patient support [CORRECT]
Correct Answer: D
Rationale: Correct because the IOM identified eight core EHR capabilities including
health information capture, results management, order entry, decision support,
electronic communication, patient support, administrative processes, and reporting.
Q3: Which term describes the science of how to use data, information, and
knowledge to improve human health and healthcare delivery?
A. Health information management
B. Nursing informatics
,C. Health informatics [CORRECT]
D. Clinical documentation improvement
Correct Answer: C
Rationale: Correct because health informatics is the interdisciplinary field that
applies information science to healthcare, encompassing the acquisition, storage,
retrieval, and use of health information to improve patient outcomes.
Q4: The system development life cycle (SDLC) includes which phases?
A. Planning and implementation only
B. Analysis and design only
C. Planning, analysis, design, implementation, evaluation, and maintenance
[CORRECT]
D. Implementation and evaluation only
Correct Answer: C
Rationale: Correct because the SDLC is a structured methodology including planning,
analysis, design, implementation, evaluation, and maintenance phases to ensure
systematic system development.
Q5: Which of the following best describes the "garbage in, garbage out" (GIGO)
principle?
A. Data quality is irrelevant to system output
B. The quality of data output depends entirely on the quality of data input [CORRECT]
C. Outdated systems should be discarded
D. Data entry is not important in EHR systems
Correct Answer: B
Rationale: Correct because GIGO means poor input data leads to poor output;
accurate, complete, and timely data entry is essential for reliable clinical decision
support and analytics.

A. To improve patient outcomes
B. To reduce healthcare costs
C. To enhance clinical decision-making
D. All of the above [CORRECT]
Correct Answer: D
Rationale: Correct because health informatics aims to improve outcomes, reduce
costs, enhance decision-making, and support evidence-based practice through the
effective use of information technology.
Q10: Which standard enables semantic interoperability by providing a common
language for clinical concepts?
A. HL7
B. FHIR
C. SNOMED CT [CORRECT]
D. DICOM
Correct Answer: C
