Section 1: Foundations of Nursing Informatics & DIKW Framework
1. A nurse informatics specialist is presenting the DIKW framework to new graduates. The
specialist explains that turning a patient's SpO₂ reading of 89% into a nursing diagnosis of
"Impaired Gas Exchange" represents which level of the framework?
A) Data
B) Information
C) Knowledge
D) Wisdom
Correct Answer: C) Knowledge
Rationale: Knowledge is the synthesis of information to identify patterns or diagnoses. The
SpO₂ reading is Data (A). Labeling it as "low" is Information (B). Connecting low SpO₂ with
crackles and dyspnea to form a diagnosis of Impaired Gas Exchange requires clinical knowledge
(C). Wisdom (D) is the application of that knowledge to change the plan of care (e.g.,
administering oxygen).
2. Which statement best defines "meaningful use" (now known as Promoting Interoperability)
in the context of EHRs?
A) Using the EHR solely for billing and coding purposes
B) Using certified EHR technology to improve quality, safety, and efficiency while engaging
patients
C) Using the EHR to replace the need for nursing clinical judgment
D) Using the EHR to store patient data for at least 10 years post-discharge
Correct Answer: B) Using certified EHR technology to improve quality, safety, and
efficiency while engaging patients
Rationale: Meaningful Use (Promoting Interoperability) is a CMS program that requires
providers to demonstrate they are using certified EHR technology in ways that improve clinical
,outcomes, engage patients, and improve care coordination. It is not purely for billing (A), does
not replace judgment (C), and is not a storage mandate (D).
3. A nurse is entering vital signs into the EHR. The system automatically populates the
patient's previous values in a graph. The nurse notices the previous systolic BP was 180, but
today it is 110. The nurse decides to reassess the patient. This scenario best illustrates:
A) Data redundancy
B) The Hawthorne effect
C) The synergy between information technology and clinical judgment
D) A system interoperability failure
Correct Answer: C) The synergy between information technology and clinical judgment
Rationale: The EHR provided the information (trended data), but it was the nurse's clinical
judgment that recognized the significant drop and prompted a reassessment. Technology
supports, but does not replace, critical thinking (C). Redundancy (A) refers to duplicate data
entry.
4. Which term describes the ability of a hospital's EHR system to exchange lab results with the
public health department's disease surveillance system automatically?
A) Interoperability
B) Scalability
C) Usability
D) Reliability
Correct Answer: A) Interoperability
Rationale: Interoperability is the ability of different information systems to communicate
and exchange data seamlessly across organizational boundaries. Scalability (B) refers to system
growth; Usability (C) refers to ease of use for the end-user.
5. The HIMSS Analytics EMRAM model stages hospitals based on their EHR adoption. At Stage
0, a hospital would most likely be characterized by:
A) Full physician documentation using structured templates
B) Closed-loop medication administration with barcoding
,C) All clinical documentation still performed on paper charts
D) Advanced CDS and clinical data warehousing
Correct Answer: C) All clinical documentation still performed on paper charts
Rationale: Stage 0 of the EMRAM model indicates that the hospital has not yet
implemented major ancillary systems (lab, pharmacy, radiology) and clinical documentation
remains entirely paper-based. Stages 5–7 represent the advanced capabilities listed in A, B, and
D.
6. A clinical informatics nurse is evaluating a new bedside documentation system. Which
usability heuristic is most directly violated if the system requires the nurse to click through 15
drop-down menus to document a simple pain reassessment?
A) Visibility of system status
B) Match between system and real world
C) User control and freedom
D) Efficiency of use
Correct Answer: D) Efficiency of use
Rationale: Efficiency of use refers to how quickly and easily a user can accomplish a task.
Requiring excessive clicks for a simple task creates a workflow bottleneck.
7. Which statement by the nurse verifies that the nurse is "information literate"?
A) "I can use software applications such as word processing, spreadsheets, and presentations."
B) "I utilize databases in the health care setting to input client information such as skin
condition."
C) "I use email over the Internet to correspond with clients and provide information."
D) "I understand how to search for a website and evaluate its usefulness for health care needs."
Correct Answer: D) "I understand how to search for a website and evaluate its usefulness
for health care needs."
Rationale: Information literacy involves the ability to recognize when information is needed
and to locate, evaluate, and effectively use that information. Options A, B, and C describe
computer literacy or basic informatics skills, not the critical evaluation component of
information literacy.
, 8. Which statement best distinguishes the difference between information literacy and
computer literacy?
A) Information literacy is the foundation of the EHR whereas computer literacy helps the nurse
to access data.
B) A nurse can extrapolate data with computer literacy and not information skills.
C) Information literacy forms the basis for ongoing learning whereas computer literacy refers to
a familiarity with the use of personal computers.
D) Information literacy is unnecessary in health care whereas computer literacy provides the
basis for computer order entry.
Correct Answer: C) Information literacy forms the basis for ongoing learning whereas
computer literacy refers to a familiarity with the use of personal computers.
Rationale: Information literacy is a broader competency that includes the ability to
recognize information needs, locate, evaluate, and apply information—forming the basis for
lifelong learning. Computer literacy is more narrowly focused on familiarity with hardware and
software.
9. The nurse gathers much data when caring for clients. Which is an example of the higher-
level "information" useful in caring for clients?
A) Lab work results include an electrolyte panel and complete blood count with differential.
B) After receiving Rocephin (ceftriaxone sodium) 1.0 gram IV yesterday, the client reported
feeling better today.
C) The client is a widowed 64-year-old black male admitted with prostatitis.
D) The vital signs are BP of 130/70, HR of 88, RR of 24, temperature of 98.8 degrees F., and
oxygen saturation of 98%.
Correct Answer: B) After receiving Rocephin (ceftriaxone sodium) 1.0 gram IV yesterday,
the client reported feeling better today.
Rationale: Information is data that has been interpreted, organized, or structured to provide
context and meaning. Option B connects a medication intervention with a patient response,
creating meaningful information. Options A, C, and D are raw data points without
interpretation.
10. The nurse understands that nursing informatics is recognized as a specialty area of
practice by which statement?
