Questions
,INTRODUCTION
This document contains 100 original verified questions designed for the WGU D220 Information
Technology in Nursing Practice Objective Assessment Comprehensive Examination for the academic year
2026/2027. The questions are distributed equally across four core domains: Domain 1 Healthcare Data
Standards and Interoperability (25 questions), Domain 2 Clinical Decision Support and Patient Safety (25
questions), Domain 3 Nursing Informatics and Electronic Health Records (EHR) (25 questions), and
Domain 4 Data Security, Privacy, and Ethical Use of Technology (25 questions). Content is original and
constructed to reinforce the official D220 course objectives for actual exam readiness and professional
proficiency in nursing informatics and health information technology, aligned to the 2026/2027 academic
year. Each question includes a correct answer designation and a rationale grounded in foundational
nursing informatics methodology.
ACTUAL QUESTIONS
Domain 1: Healthcare Data Standards and Interoperability
Question 1. Which standard is widely used for the exchange of clinical documents such as
discharge summaries and progress notes between healthcare systems?
A. HL7 Clinical Document Architecture (CDA) / Consolidated CDA (C-CDA)
B. DICOM exclusively for all data types
C. SMTP email protocol only
D. FTP without encryption
Correct Answer: A
Rationale: HL7 CDA and its Consolidated CDA implementation are designed for structured clinical
document exchange and support interoperability between electronic health record systems.
Question 2. What is the primary purpose of SNOMED CT in healthcare information
systems?
A. Billing and claims submission only
B. Medical device connectivity exclusively
C. Providing a comprehensive clinical terminology for documenting and coding clinical concepts
D. Replacing all laboratory value reporting
Correct Answer: C
Rationale: SNOMED CT is a comprehensive, multilingual clinical terminology that enables consistent
capture, retrieval, and exchange of clinical data across systems.
Question 3. Which organization develops and maintains LOINC codes commonly used for
laboratory and clinical observations?
A. World Health Organization exclusively
B. Regenstrief Institute (LOINC)
C. American Medical Association CPT panel only
D. International Organization for Standardization for all codes
Correct Answer: B
Rationale: LOINC (Logical Observation Identifiers Names and Codes) is maintained by the Regenstrief
Institute and provides universal identifiers for laboratory and clinical observations.
Question 4. What does FHIR stand for in health information technology?
A. Federal Health Information Registry
B. Fast Hospital Integration Resource
C. Full Healthcare Interoperability Record
D. Fast Healthcare Interoperability Resources
WGU D220 Information Technology in Nursing Practice Objective Assessment Comprehensive Examination 2026/2027 | Verified
Questions
, Correct Answer: D
Rationale: FHIR (Fast Healthcare Interoperability Resources) is a modern HL7 standard designed to
enable easier, more flexible exchange of healthcare data using modern web technologies.
Question 5. Which coding system is primarily used in the United States for reporting
diagnoses on claims and for epidemiological statistics?
A. ICD-10-CM
B. SNOMED CT exclusively for billing
C. RxNorm for diagnoses
D. CPT for all diagnoses
Correct Answer: A
Rationale: ICD-10-CM is the official system for diagnosis coding in the United States for billing,
reporting, and public health statistics.
Question 6. What is the main benefit of using standardized terminologies such as SNOMED
CT and LOINC in an EHR?
A. Eliminating the need for any human documentation
B. Preventing all medication errors automatically
C. Enabling semantic interoperability so that data can be understood and used consistently across
systems
D. Removing the requirement for data security
Correct Answer: C
Rationale: Standardized terminologies support semantic interoperability by ensuring that clinical
concepts are represented consistently, allowing systems and users to interpret data the same way.
Question 7. Which standard is the predominant imaging standard for medical images such
as radiology studies?
A. HL7 v2 only
B. DICOM (Digital Imaging and Communications in Medicine)
C. CSV flat files
D. PDF without metadata
Correct Answer: B
Rationale: DICOM is the international standard for the communication and management of medical
imaging information and related data.
Question 8. In the context of interoperability, what does the term “semantic
interoperability” mean?
A. Only the ability to transmit bits between systems
B. Identical user interfaces across all applications
C. Shared network cables between hospitals
D. The ability of systems to exchange data with shared meaning so that the receiving system can
interpret the data correctly
Correct Answer: D
Rationale: Semantic interoperability goes beyond syntactic exchange; it ensures that the meaning of the
data is preserved and understood by the receiving system and its users.
Question 9. Which federal initiative promotes nationwide health information exchange
and the use of certified EHR technology?
A. Office of the National Coordinator for Health Information Technology (ONC) programs and related
interoperability rules
B. Exclusive use of paper records
