Fundamentals of Health Informatics (Questions 1-15)
Q1: What is health informatics primarily concerned with?
• A) Financial accounting in hospitals
• B) Managing healthcare data and information
• C) Staffing healthcare organizations
• D) Medical equipment manufacturing
Answer: B
Rationale: Health informatics deals with the collection, storage, retrieval, communication, and
optimal use of health-related data, information, and knowledge. It focuses on using data and
technology to improve healthcare delivery across all fields of medicine, not just hospitals .
Q2: Data becomes information when it is:
• A) Deleted from the system
• B) Processed and organized
• C) Stored in a database
• D) Encrypted for security
Answer: B
Rationale: Data consists of symbols and observations without inherent meaning. When data is
processed and organized in a meaningful way, it becomes information from which conclusions can
be drawn .
Q3: Which of the following best describes the knowledge level in the DIKW pyramid?
• A) Raw, unprocessed facts
• B) Information that is justifiable to be true
• C) Critical use of knowledge to make decisions
• D) Meaningful data from which conclusions are drawn
Answer: B
, WGU D027
Rationale: Knowledge is information that is justifiable to be true. The DIKW hierarchy moves from
Data (raw symbols) → Information (meaningful data) → Knowledge (justifiable information) →
Wisdom (critical application of knowledge) .
Q4: Informatics combines which two fields?
• A) Medicine and Law
• B) Information Technology and Healthcare
• C) Finance and Information Technology
• D) Marketing and Healthcare
Answer: B
Rationale: Health informatics is an interdisciplinary field that sits at the intersection of information
technology, data science, and healthcare delivery .
Q5: What is a key benefit of informatics in healthcare?
• A) Slower patient care delivery
• B) Improved decision-making for clinicians
• C) More paperwork for staff
• D) Less accessible patient data
Answer: B
Rationale: Informatics improves healthcare by enhancing data access and providing clinicians with
better information for decision-making, ultimately improving patient safety and care quality .
Q6: Informatics improves patient care by:
• A) Reducing communication between providers
• B) Enhancing data access across care settings
• C) Eliminating the need for patient records
• D) Increasing manual documentation tasks
Answer: B
Rationale: Health informatics systems enable better data access and sharing, which improves care
coordination, reduces errors, and supports evidence-based practice .
Q7: Which is NOT a component of health informatics?
• A) Data management
, WGU D027
• B) Technology infrastructure
• C) Clinical workflow
• D) Architecture design of buildings
Answer: D
Rationale: Health informatics involves data, technology, and workflow optimization in healthcare
settings. Architecture design of buildings is unrelated to the field .
Q8: The main goal of health information technology is to:
• A) Increase the amount of paperwork
• B) Improve healthcare delivery through better data management
• C) Replace physicians with computers
• D) Reduce the number of healthcare staff needed
Answer: B
Rationale: Health IT aims to improve healthcare delivery through better data management,
accessibility, and clinical decision support. It enhances, rather than replaces, clinical care .
Q9: Health IT helps reduce which of the following?
• A) Staffing requirements
• B) Medical errors
• C) Patient volumes
• D) Equipment needs
Answer: B
Rationale: One of the primary benefits of health IT is reducing medical errors through features like
CPOE, clinical decision support, and barcode medication administration .
Q10: Which area of informatics deals with diagnosis and management with emphasis on
physicians?
• A) Clinical informatics
• B) Bioinformatics
• C) Medical informatics
• D) Public informatics
Answer: C
, WGU D027
Rationale: Medical informatics specifically focuses on diagnosis and management with emphasis on
physicians. Clinical informatics covers broader clinical decision support and documentation .
Q11: Bioinformatics is best described as the study of:
• A) Hospital administration systems
• B) Biomedical information for scientific inquiry and problem-solving
• C) Patient billing and coding
• D) Public health surveillance
Answer: B
Rationale: Bioinformatics pursues the effective uses of biomedical information and knowledge for
scientific inquiry, problem-solving, and decision-making motivated by efforts to improve human
health .
Q12: Clinical informatics includes which of the following?
• A) Only hospital administration
• B) Clinical decision support, clinical documentation, and provider order entry
• C) Public health surveillance only
• D) Medical research exclusively
Answer: B
Rationale: Clinical informatics encompasses systems from clinical decision support to clinical
documentation to provider order entry systems .
Q13: Public informatics focuses on:
• A) Hospital financial management
• B) Public health surveillance, reporting, and health problems
• C) Individual patient diagnosis
• D) Medical equipment inventory
Answer: B
Rationale: Public informatics addresses areas of public health including surveillance, reporting, and
addressing population health problems .
Q14: Which of the following accurately describes the difference between data and information?
• A) Data is meaningful; information is meaningless
