WGU D190 Introduction to Healthcare IT Systems 2026/2027 | Exam
Questions, Answers & Detailed Rationales
Overview:
• This comprehensive exam resource contains 200 carefully structured multiple-
choice questions with complete rationales to help you master all core competencies
in Healthcare IT Systems
• Study systematically by topic area, review detailed rationales after each question,
and use this material to reinforce understanding of healthcare information
technology principles and applications
SECTION 1: HEALTHCARE IT FUNDAMENTALS
1. What is the primary purpose of an Electronic Health Record (EHR) system?
A) To reduce healthcare costs by eliminating paper records
B) To provide a comprehensive digital record of a patient's medical history and
health information
C) To serve as a billing tool for insurance companies
D) To replace the need for clinical staff in hospitals
E) To store only pharmaceutical prescriptions
CORRECT ANSWER: B) To provide a comprehensive digital record of a patient's
medical history and health information
Rationale: The primary purpose of an EHR system is to maintain a comprehensive,
accessible digital record of all patient health information including medical history,
diagnoses, medications, allergies, laboratory results, and clinical encounters. While
EHRs may have secondary benefits like reducing costs, their fundamental purpose
is to consolidate and digitize patient information for continuity of care. The EHR is
not limited to just billing or prescriptions, and clinical staff remain essential despite
electronic systems.
,2. Which of the following best defines Health Information Technology (Health
IT)?
A) Technology used solely for medical billing and insurance claims
B) The technology infrastructure and systems used to manage health information
and support healthcare operations
C) Computers and internet connections only
D) Software designed exclusively for pharmaceutical companies
E) Technology that replaces all healthcare professionals
CORRECT ANSWER: B) The technology infrastructure and systems used to
manage health information and support healthcare operations
Rationale: Health IT encompasses the comprehensive infrastructure, systems, and
applications used to capture, store, manage, analyze, and exchange health
information. It includes EHRs, health information exchanges, clinical decision
support systems, and many other technologies. While billing is one component,
Health IT extends far beyond that to support all aspects of healthcare delivery,
administration, and quality improvement.
3. What is a key advantage of digital health records over paper-based records?
A) They eliminate the need for patient privacy protection
B) They allow simultaneous access by multiple authorized users at different
locations
C) They are less expensive to maintain than paper records
D) They do not require backup systems
E) They eliminate the need for healthcare providers
CORRECT ANSWER: B) They allow simultaneous access by multiple authorized
users at different locations
,Rationale: Digital health records enable multiple authorized healthcare providers
and staff members to access the same patient information simultaneously from
different physical locations, improving care coordination and efficiency. While
digital records may eventually reduce costs, initial implementation can be
expensive. Digital records still require robust backup and disaster recovery systems
and do not eliminate the need for providers. Privacy protections remain equally
important in digital systems as in paper systems.
4. Which regulatory framework establishes privacy and security standards for
protected health information in the United States?
A) The Americans with Disabilities Act
B) The HIPAA Privacy and Security Rules
C) The Food and Drug Administration Act
D) The Affordable Care Act exclusively
E) State licensing boards only
CORRECT ANSWER: B) The HIPAA Privacy and Security Rules
Rationale: The Health Insurance Portability and Accountability Act (HIPAA)
establishes the Privacy Rule and Security Rule that define standards for protecting
protected health information (PHI) in the United States. These rules apply to
covered entities and business associates. While the ACA modified some healthcare
regulations, HIPAA remains the primary federal framework for health information
privacy and security. The other options either address different regulatory areas or
lack the comprehensive scope of HIPAA.
5. What does "interoperability" mean in the context of Healthcare IT systems?
A) The ability to turn off systems when not in use
B) The capacity of different healthcare IT systems to exchange and use data
effectively
, C) The process of training staff on new software
D) The cost of maintaining computer networks
E) The physical location of computer servers
CORRECT ANSWER: B) The capacity of different healthcare IT systems to
exchange and use data effectively
Rationale: Interoperability refers to the ability of diverse healthcare information
systems to communicate, exchange data, and work together seamlessly. This is
critical for ensuring that patient information can flow between different providers,
settings, and systems. Semantic interoperability ensures that exchanged
information is understood and used correctly. Technical interoperability enables
the systems to communicate. The other options refer to different IT concepts but
not interoperability.
6. Which of the following is NOT a primary component of Health IT
infrastructure?
A) Hardware and networking equipment
B) Electronic Health Record systems
C) Healthcare provider personal vehicles
D) Security and backup systems
E) Clinical decision support software
CORRECT ANSWER: C) Healthcare provider personal vehicles
Rationale: While healthcare providers use personal vehicles for transportation,
they are not part of Health IT infrastructure. Health IT infrastructure includes the
technology systems and equipment specifically designed to manage health
information and support healthcare operations, such as servers, networks, EHRs,
databases, security systems, and clinical applications. Personal vehicles are not
information technology infrastructure components.
