and Answers with Detailed Rationales – Pass
Guaranteed – A+ Graded
Domain: Foundations of Nursing Informatics
Q1: The TIGER Initiative (Technology Informatics Guiding Education Reform) was
established to achieve which primary goal?
A. Standardize electronic health record systems across all healthcare organizations
B. Integrate informatics competencies into nursing education and practice
C. Develop new software applications for nursing documentation
D. Eliminate paper-based charting in hospitals
Correct Answer: B
Rationale: B. [CORRECT] The TIGER Initiative focused on preparing the nursing
workforce to use technology and informatics to improve patient care by integrating
informatics competencies into nursing education, practice, and leadership. A, C, and D
are not the primary goals.
Q2: According to the American Nurses Association (ANA), which of the best defines
nursing informatics?
A. The use of computer hardware to manage financial data in healthcare
B. The specialty that integrates nursing science, computer science, and information
science to manage and communicate data, information, knowledge, and wisdom in
nursing practice
C. The study of algorithms used exclusively for medical diagnosis
D. The process of converting paper records into digital formats
Correct Answer: B
Rationale: B. [CORRECT] The ANA defines nursing informatics as the integration of
nursing science with multiple information management and analytical sciences to
identify, define, manage, and communicate data, information, knowledge, and wisdom
in nursing practice. A is incorrect; it describes health information management or IT. C is
incorrect; it limits informatics to algorithms and medical (not nursing) diagnosis. D is
incorrect; it describes digitization, a mere fraction of informatics.
,Q3: A nurse informaticist is trying to understand why some nurses on a unit quickly
adopt a new charting system while others resist it. The informaticist applies a theory that
categorizes individuals as innovators, early adopters, early majority, late majority, and
laggards. Which theory is being used?
A. Technology Acceptance Model (TAM)
B. Diffusion of Innovation Theory
C. Unified Theory of Acceptance and Use of Technology (UTAUT)
D. Maslow's Hierarchy of Needs
Correct Answer: B
Rationale: B. [CORRECT] Everett Rogers' Diffusion of Innovation Theory explains how,
why, and at what rate new ideas and technology spread, specifically categorizing
adopters into the five listed groups. A is incorrect; TAM focuses on perceived usefulness
and ease of use. C is incorrect; UTAUT combines multiple constructs (performance
expectancy, effort expectancy, etc.) but does not use Rogers' specific adopter
categories. D is incorrect; Maslow's theory relates to human motivation, not technology
adoption.
Q4: The Technology Acceptance Model (TAM) posits that two primary factors influence
a user's decision to accept and use a new technology. What are these two factors?
A. Cost and technical support
B. Perceived usefulness and perceived ease of use
C. Organizational support and peer pressure
D. System complexity and network speed
Correct Answer: B
Rationale: B. [CORRECT] TAM identifies perceived usefulness (the degree to which a
person believes the system will enhance job performance) and perceived ease of use
(the degree to which a person believes using the system will be effort-free) as the
fundamental determinants of user acceptance. A, C, and D are external variables that
might indirectly influence perceptions, but they are not the core constructs of TAM.
Q5: What distinguishes an Informatics Nurse Specialist (INS) from a nurse who simply
has basic computer skills?
A. The INS focuses exclusively on hardware repair and network troubleshooting
B. The INS has advanced graduate education and focuses on the transformation of data
into knowledge to improve patient outcomes
C. The INS only works in the IT department and has no direct patient care
responsibilities
D. The INS is primarily responsible for entering patient data into the EHR
Correct Answer: B
Rationale: B. [CORRECT] An INS possesses advanced education (usually a master's or
doctorate) and specializes in integrating informatics science to support decision-making,
, optimize systems, and improve outcomes. A is incorrect; it describes an IT technician. C
is incorrect; INSs often bridge IT and clinical practice, working directly with end-users. D
is incorrect; it describes a basic end-user, not a specialist.
Q6: Which of the following represents a basic informatics competency expected of all
registered nurses, as opposed to an advanced competency?
A. Designing a clinical decision support algorithm
B. Participating in the selection of a new EHR system
C. Using a barcode medication administration (BCMA) system safely and accurately
D. Evaluating the impact of health IT on patient outcomes at an organizational level
Correct Answer: C
Rationale: C. [CORRECT] Basic informatics competencies include the ability to use
technology effectively and safely at the point of care, such as using BCMA or
documenting in an EHR. A, B, and D are advanced competencies requiring specialized
informatics education, involving system design, strategic implementation, and high-level
evaluation.
Q7: A hospital CEO asks the informatics team to develop a system to track billing,
supply chain management, and human resources. This type of system is best classified
as a(n):
A. Clinical information system
B. Administrative information system
C. Electronic health record
D. Health information exchange
Correct Answer: B
Rationale: B. [CORRECT] Administrative information systems manage financial,
logistical, and operational aspects of healthcare (billing, scheduling, HR). A is incorrect;
clinical systems manage patient care data (e.g., vitals, labs). C is incorrect; EHRs are
specific integrated clinical record systems. D is incorrect; HIE is the sharing of data
between organizations.
Q8: Historically, the evolution of nursing informatics shifted from a focus on data
processing to a focus on:
A. Hardware procurement
B. Knowledge generation and decision support
C. Replacing physicians
D. Eliminating the need for nursing documentation
Correct Answer: B
Rationale: B. [CORRECT] The evolution of informatics followed the DIKW pyramid,
moving from early focus on computers and data processing (1960s-1970s) to
information management (1980s), and finally to knowledge generation, clinical decision
