Objective Assessment | Nursing Informatics
1. A nurse enters a patient's vital signs into the electronic health record
(EHR). According to the DIKW hierarchy, these vital signs are best classified
as:
A) Information
B) Knowledge
C) Data
D) Wisdom
Correct Answer: Data
Rationale: In the DIKW hierarchy, data are distinct characters, numbers, or
facts gathered for analysis and described objectively without interpretation.
Vital signs such as heart rate and blood pressure are raw facts entered into
the EHR. Information is data that has been interpreted, knowledge is
synthesized information, and wisdom is the appropriate use of knowledge.
2. A clinical dashboard displays a graph showing the last six months of
patient fall data for acute care units. In the DIKW hierarchy, this graph is an
example of:
A) Data
B) Information
C) Knowledge
D) Wisdom
Correct Answer: Information
Rationale: Information is data that have been interpreted into meaning and is
usually organized or structured. A graph of fall data takes raw numbers and
,organizes them into a meaningful visual representation. Data are the raw
numbers themselves, knowledge is synthesized information from multiple
sources, and wisdom is the ethical application of knowledge.
3. A nurse uses an evidence-based protocol to recognize early signs of
patient deterioration and intervene appropriately. This action best
demonstrates which level of the DIKW hierarchy?
A) Data
B) Information
C) Knowledge
D) Wisdom
Correct Answer: Wisdom
Rationale: Wisdom is the ability to appropriately use knowledge to recognize
and handle complex problems and is critical to the effective and ethical use
of data, information, and knowledge. Applying an evidence-based protocol to
recognize deterioration and intervene demonstrates wisdom in practice.
4. A beginning nurse is expected to have which of the following informatics
competencies?
A) Design and implement new clinical information systems
B) Lead organizational informatics strategy and policy development
C) Fundamental information-management and computer-technology skills
D) Advanced data analytics and predictive modeling
Correct Answer: Fundamental information-management and computer-
technology skills
,Rationale: Level 1 (beginning nurse) informatics competencies include
fundamental information-management and computer-technology skills,
structured data entry, and processing information appropriately. System
design and leadership are competencies of informatics specialists and
innovators.
5. An experienced nurse uses desktop software to organize data for better
patient care and collaborates with the informatics nurse specialist to suggest
system improvements. This nurse is demonstrating competencies expected
at which level?
A) Level 1—Beginning nurse
B) Level 2—Experienced nurse
C) Level 3—Informatics specialist
D) Level 4—Informatics innovator
Correct Answer: Level 2—Experienced nurse
Rationale: Experienced nurses are skilled in using information management
and computer technology, have strong analytic skills to learn from
relationships between different data elements, and collaborate with
informatics nurse specialists to suggest system improvements.
6. According to the course materials, nurses are considered "knowledge
workers" because they:
A) Work primarily with computers and information systems
B) Use knowledge from education and experience to gather data and make
patient care decisions
C) Focus exclusively on technology implementation
D) Are responsible for maintaining the EHR system
, Correct Answer: Use knowledge from education and experience to gather
data and make patient care decisions
Rationale: Nurses are knowledge workers because they use knowledge
gained in school and from their experiences and interactions with patients to
gather data and make daily patient care decisions. They continuously learn
and use evidence-based information when possible.
7. A nurse notices a patient's respiratory rate is 40 breaths per minute,
recognizes this is outside the normal range, and contacts the provider. This
scenario best illustrates the nurse functioning as a:
A) Data entry specialist
B) Knowledge worker
C) Informatics innovator
D) System administrator
Correct Answer: Knowledge worker
Rationale: The nurse uses knowledge of normal values (gained from
education and experience) to recognize abnormal data and take appropriate
action. This demonstrates the integration of knowledge with clinical decision-
making, which is the essence of a knowledge worker.
8. Which of the following is a key competency for nursing informatics
specialists?
A) Basic computer literacy
B) Fundamental data entry skills
C) Ability to design and implement information systems
D) Proficiency in using only one specific EHR
