1. Which definition best describes the core scope of nursing informatics as a specialized
area of practice?
A. The sole management of electronic medical record database servers within a healthcare
organization
B. The integration of nursing science, computer science, and information science to manage and
communicate data, information, knowledge, and wisdom
C. The physical installation and routine maintenance of clinical telemetry monitoring systems in
acute care units
D. The clinical administration of medication administration software used exclusively by
pharmacy technicians
Answer: B
RATIONALE: Nursing informatics integrates nursing science, computer science, and
information science to manage and communicate data, information, knowledge, and wisdom
in nursing practice, driving evidence-based patient care.
2. A nurse manager is explaining the foundational DIKW framework to a new committee
member. Which example represents data?
A. A patient's heart rate recorded as 112 beats per minute
B. A nursing note stating that a patient is experiencing symptomatic sinus tachycardia
C. An alert indicating that three patients in the unit have elevated heart rates following
medication administration
D. A protocol established to automatically administer beta-blockers when heart rate exceeds set
parameters
Answer: A
RATIONALE: Data consists of raw, uninterpreted facts or discrete observations without
context, such as a standalone numerical vital sign reading like a heart rate of 112 bpm.
,3. In the context of clinical decision support systems (CDSS), how is "knowledge"
differentiated from "information"?
A. Knowledge consists of raw numbers, whereas information represents basic patient
demographics
B. Knowledge applies rules, relationships, and context to information to guide clinical decision-
making
C. Knowledge is stored exclusively on local server hardware, while information is stored in
cloud databases
D. Knowledge refers only to historical patient charts archived for legal compliance
Answer: B
RATIONALE: Knowledge synthesizes information by identifying relationships, applying clinical
rules, and adding context, which allows clinicians to make informed decisions and take clinical
action.
4. A hospital informatics team is standardizing terminology across the electronic health
record (EHR) to support nursing practice. Which terminology is recognized specifically as
a standardized nursing language?
A. CPT (Current Procedural Terminology)
B. ICD-10-CM
C. ICNP (International Classification for Nursing Practice)
D. LOINC (Logical Observation Identifiers Names and Codes)
Answer: C
RATIONALE: The International Classification for Nursing Practice (ICNP) is a formally

5. During a system deployment, a informatics nurse specialist emphasizes the use of
SNOMED CT. What is the primary purpose of utilizing SNOMED CT in clinical
documentation?
A. Standardizing billing codes for outpatient physician office visits
B. Providing a comprehensive, multilingual clinical healthcare terminology for detailed clinical
data capture
,C. Encoding laboratory test requests and results for universal lab system interface
D. Categorizing hospital inpatient facility reimbursement tiers
Answer: B
RATIONALE: SNOMED CT provides a validated, highly detailed, standardized clinical
terminology used internationally to capture clinical health concepts accurately across EHR
systems.
6. A nurse is documenting a patient's wound care assessment in the EHR using drop-down
menus rather than free-text notes. What is the main advantage of using structured data
entry?
A. It allows unlimited creative expression for nursing staff
B. It enables automated data query, retrieval, and aggregate data analysis for quality
improvement
C. It eliminates the requirement for login authentication when entering patient records
D. It decreases the overall speed of documentation for novice clinicians
Answer: B
RATIONALE: Structured data entry uses discrete fields that allow data to be easily searched,
extracted, aggregated, and analyzed for quality reporting, clinical research, and decision
support.
7. An informatics nurse is evaluating the health literacy level of educational materials
stored within the patient portal. Which readability level is recommended for general
patient education resources?
A. 10th to 12th grade reading level
B. 5th to 6th grade reading level
C. College undergraduate reading level
D. Advanced graduate reading level
Answer: B
, RATIONALE: Health literacy best practices recommend that patient education materials be
written at a 5th to 6th grade reading level to ensure comprehension across diverse patient
populations.
8. Which federal regulation in the United States established national standards for the
protection of individually identifiable health information (PHI)?
A. HITECH Act
B. HIPAA Privacy Rule
C. Affordable Care Act (ACA)
D. Clinical Laboratory Improvement Amendments (CLIA)
Answer: B
RATIONALE: The HIPAA Privacy Rule established federal privacy standards to safeguard
individually identifiable health information held by covered entities and their business
associates.
9. Under the HIPAA Security Rule, which measure represents an Administrative
Safeguard?
A. Installing biometric thumbprint scanners on medication dispensing cabinets
B. Implementing automatic log-off timers on computer workstations
C. Conducting mandatory annual security awareness training for all healthcare staff
D. Placing physical security guards at data center entrance doors
Answer: C
RATIONALE: Administrative safeguards are administrative actions, policies, and procedures to
manage the selection, development, implementation, and maintenance of security measures,
such as staff training.
10. A nurse leaves a computer terminal logged in and unattended while stepping into a
patient room to assist with a fall. A visitor views another patient's medical records. What
type of failure occurred?
A. Physical transmission error
B. Technical software bug
