NUR 226 INFORMATICS IN NURSING EXAM PREDICTOR
2026/27 Q&A
1. Which of the following best describes the primary purpose of a
Clinical Decision Support System (CDSS) in nursing informatics?
A. To replace nursing judgment in patient care decisions
B. To provide evidence-based recommendations and alerts to
support clinical decision-making
C. To automate all nursing documentation processes
D. To store patient records without analytical capabilities
Correct Answer: B
Explanation: CDSS provides evidence-based recommendations,
alerts, and reminders to support clinical decision-making while
augmenting (not replacing) nursing judgment. Options A, C, and D
misrepresent the supportive rather than replacement role of CDSS.
2. In the context of healthcare interoperability, what does HL7
version 2.x primarily facilitate?
A. Semantic interoperability through standardized ontologies
B. Messaging and data exchange between healthcare information
systems
C. Complete integration of all healthcare applications
D. Patient identity management across organizations
Correct Answer: B
Explanation: HL7 v2.x is primarily a messaging standard that
facilitates data exchange between healthcare systems. Semantic
interoperability (A) requires terminologies like SNOMED CT,
, complete integration (C) is not achievable with HL7 alone, and
patient identity (D) uses different standards like MPI.
3. A nurse is documenting patient care in an Electronic Health
Record (EHR). Which principle of nursing documentation is most
critical for legal protection?
A. Using abbreviations to save time
B. Documenting only abnormal findings
C. Timely, accurate, and complete documentation of all
assessments and interventions
D. Documenting at the end of the shift for efficiency
Correct Answer: C
Explanation: Timely, accurate, and complete documentation is
legally essential and reflects the standard of care. Abbreviations
(A) can cause errors, documenting only abnormalities (B) omits
critical negative findings, and delayed documentation (D)
compromises accuracy and legal defensibility.
4. Which HIPAA safeguard specifically protects electronic protected
health information (ePHI) from unauthorized access through
technical measures?
A. Administrative safeguards
B. Physical safeguards
C. Technical safeguards
D. Organizational safeguards
Correct Answer: C
Explanation: Technical safeguards include access controls,
, encryption, audit controls, and authentication mechanisms that
protect ePHI. Administrative safeguards (A) involve policies and
procedures, physical safeguards (B) protect physical access to
systems, and organizational safeguards (D) involve business
associate agreements.
5. What is the primary benefit of using standardized nursing
terminologies like NANDA-I, NIC, and NOC in electronic
documentation?
A. Reducing the time required for documentation
B. Enabling data aggregation, comparison, and research across
institutions
C. Eliminating the need for clinical judgment
D. Simplifying the user interface of EHR systems
Correct Answer: B
Explanation: Standardized terminologies enable data aggregation,
comparison, research, and outcome measurement across settings.
They don't necessarily reduce documentation time (A), don't
eliminate clinical judgment (C), and may initially complicate rather
than simplify interfaces (D).
6. In nursing informatics, what does the term "data integrity"
primarily refer to?
A. The speed of data retrieval from databases
B. The accuracy, completeness, and consistency of data
throughout its lifecycle
C. The encryption strength of stored data
, D. The number of users who can access the data
Correct Answer: B
Explanation: Data integrity refers to maintaining accuracy,
completeness, and consistency of data throughout its lifecycle.
Speed (A) relates to performance, encryption (C) relates to
security, and user access (D) relates to access control.
7. Which of the following represents a critical failure in health
information exchange (HIE) that could directly impact patient
safety?
A. Delayed transmission of non-critical lab results
B. Inability to access patient allergy information during emergency
care
C. Slow system performance during off-peak hours
D. Inability to print patient statements
Correct Answer: B
Explanation: Inability to access allergy information during
emergencies poses immediate patient safety risks. Delayed non-
critical results (A), slow off-peak performance (C), and printing
issues (D) are convenience issues but not critical safety threats.
8. What is the primary purpose of computerized provider order
entry (CPOE) systems in nursing practice?
A. To eliminate the need for nurse-physician communication
B. To reduce medication errors through standardized ordering and
decision support
C. To automatically administer medications without nurse
