BEST demonstrated by this practice?
A. Data redundancy
B. Timely data capture
C. Data abstraction
D. Information compression
Answer: B
Timely documentation captures clinical data close to the time it is generated, improving
accuracy, continuity of care, and the usefulness of information for subsequent clinical
decisions.

3. Which term refers to raw facts that have not yet been interpreted or organized into
meaning?
A. Data
B. Knowledge

4. A nurse reviews a patient's blood pressure readings over several days and recognizes a
persistent upward trend. The nurse is primarily converting data into which concept?
A. Wisdom
B. Metadata
C. Information
D. Knowledge management
Answer: C
Organizing individual blood pressure measurements into a meaningful trend transforms raw
data into information that can be interpreted clinically.
5. Which example BEST represents nursing informatics?
A. Performing a manual wound dressing
B. Using clinical data to improve nursing care processes
C. Taking a patient's temperature
D. Transporting a patient to radiology
Answer: B
Nursing informatics integrates nursing science, information science, and computer science to

6. A nurse receives an electronic alert that a prescribed medication may interact with
another medication the patient is taking. Which EHR function is being demonstrated?
A. Clinical decision support
B. Data archiving
C. Patient registration
D. Inventory management
Answer: A

recommendations that assist clinicians in making safer and more informed decisions.
7. Which action BEST protects the confidentiality of patient information in an electronic
health record?
A. Sharing a password with a trusted coworker
B. Leaving the workstation unlocked during rounds
C. Using individual authentication credentials
D. Printing the patient's entire chart for convenience
Answer: C
,Individual authentication credentials establish accountability and restrict access to authorized

8. A nurse enters the wrong blood pressure into an electronic record and immediately
recognizes the error. What is the most appropriate action?
A. Delete the entire nursing note
B. Correct the entry according to organizational policy
C. Ask another nurse to change the entry
D. Ignore the error if it did not affect treatment
Answer: B
Electronic documentation errors should be corrected transparently according to
organizational policy so the record maintains an accurate and auditable history.
9. Which component of the DIKW framework represents the application of knowledge to
make an appropriate clinical decision?
A. Data
B. Information
C. Knowledge
D. Wisdom
Answer: D
Wisdom represents the appropriate application of knowledge and understanding to clinical
situations and decision-making.
10. A hospital introduces barcode medication administration (BCMA). What is the
PRIMARY purpose of this technology?
A. Reduce the need for nursing assessment
B. Improve medication identification and administration safety
C. Eliminate medication reconciliation
D. Replace pharmacist verification
Answer: B
BCMA verifies patient and medication information electronically, helping reduce
identification and administration errors while supporting established medication-safety
processes.
11. Which characteristic is MOST important when evaluating the quality of clinical data?
A. Accuracy
B. Volume
C. Complexity
D. Frequency of printing
, Answer: A
Accurate data are essential because inaccurate clinical information can lead to inappropriate
decisions, treatment errors, and compromised patient outcomes.
12. A nurse accesses a patient's record solely because the patient is a well-known
community member. Which principle has been violated?
A. Data normalization
B. Minimum necessary access
C. Clinical interoperability
D. Data visualization
Answer: B
Access to patient information should be limited to legitimate professional purposes and the
minimum information necessary to perform authorized duties.
13. What is interoperability in healthcare information systems?
A. The ability of systems to exchange and use information
B. The replacement of all paper documents
C. The use of identical computer hardware
D. The elimination of clinical judgment
Answer: A
Interoperability allows different information systems to exchange, interpret, and
appropriately use health information.
14. A patient moves from one hospital to another, and the receiving facility electronically
obtains relevant medication and allergy information. Which benefit of interoperability is
MOST directly demonstrated?
A. Reduced clinical communication
B. Improved continuity of care
C. Increased data duplication
D. Elimination of patient consent requirements
Answer: B
Interoperable systems allow relevant information to follow the patient, supporting safer
transitions and continuity of care.
15. Which nursing action demonstrates the use of evidence-based informatics practice?
A. Selecting an intervention solely because it is familiar
B. Using current evidence and patient data to guide care
C. Ignoring electronic clinical guidelines
