1. What is the primary purpose of nursing informatics?
A. To replace nurses with automated systems
B. To eliminate the need for clinical judgment
C. To integrate nursing science, information science, and computer
science to manage and communicate data and knowledge
D. To focus exclusively on electronic health records
Answer: C. To integrate nursing science, information science, and
computer science to manage and communicate data and knowledge
Rationale: Nursing informatics combines nursing science with
information and computer sciences to support the management of
data, information, knowledge, and wisdom in nursing practice. Its
,purpose is to improve patient care, decision-making, communication,
education, and healthcare outcomes rather than replace nurses or
clinical judgment.
2. Which term refers to raw, unprocessed facts about a patient?

involves applying knowledge appropriately to patient care.
3. A nurse reviews a patient's temperature, heart rate, respiratory
rate, and blood pressure and recognizes that the findings indicate
possible infection. This demonstrates the transformation of data
into:
A. Hardware
B. Information
,C. Encryption
