SECTION 1: FOUNDATIONS OF NURSING INFORMATICS (Questions 1–25)
1. According to the American Nurses Association, which statement best defines nursing informatics?
A. The maintenance of computer hardware in healthcare facilities
B. The integration of nursing science with information and analytical sciences to manage data, information,
knowledge, and wisdom in nursing practice
C. The administrative management of hospital billing systems
D. The exclusive use of telehealth platforms for patient care
Correct Answer: B — The integration of nursing science with information and analytical sciences to manage
data, information, knowledge, and wisdom in nursing practice
Rationale: Nursing informatics integrates nursing science with information and analytical sciences to identify,
define, manage, and communicate data, information, knowledge, and wisdom in nursing practice. It is not
limited to hardware (A), billing (C), or telehealth (D).
2. Which framework is commonly used in nursing informatics to describe the progression from raw facts to
clinical decision-making?
A. The nursing process
B. The DIKW framework
C. Maslow's hierarchy
,D. The medical model
Correct Answer: B — The DIKW framework
Rationale: The Data-Information-Knowledge-Wisdom (DIKW) framework describes how raw data are
transformed into information, then knowledge, and ultimately wisdom for clinical decision-making. The
nursing process (A), Maslow's hierarchy (C), and the medical model (D) are unrelated frameworks.
3. A nurse records a patient's temperature as 38.5°C. In the DIKW framework, this recording represents which
concept?
A. Data
B. Information
C. Knowledge
D. Wisdom
Correct Answer: A — Data
Rationale: Data are raw, uninterpreted facts or observations. A single temperature reading is a data point.
Information (B) emerges when data are organized and given context. Knowledge (C) involves synthesizing
information with clinical understanding. Wisdom (D) is the application of knowledge to make decisions.
4. A nurse reviews a patient's temperature readings over 3 days and recognizes a persistent upward trend. In
the DIKW framework, this recognition represents which concept?
A. Data
B. Information
, C. Wisdom
D. Hardware processing
Correct Answer: B — Information
Rationale: Organizing individual data points (temperatures) into a meaningful pattern (upward trend)
transforms data into information. Knowledge (C) would involve understanding the clinical significance of the
trend. Wisdom (D) would involve applying that understanding to make a decision.
5. A nurse recognizes that a patient's rising temperature, increased heart rate, and elevated white blood cell
count together suggest infection. In the DIKW framework, this synthesis represents which concept?
A. Data
B. Information
C. Knowledge
D. Wisdom
Correct Answer: C — Knowledge
Rationale: Knowledge involves synthesizing information (patterns of findings) with clinical understanding to
recognize clinical significance, such as identifying signs of infection. Data (A) are raw facts. Information (B) is
organized data. Wisdom (D) is the application of knowledge to make a decision.
6. A nurse applies clinical knowledge to determine that a patient requires immediate intervention and notifies
the provider. In the DIKW framework, this decision represents which concept?
A. Data
