Question 1
Which statement best describes the primary purpose of health
information technology (HIT) in nursing practice?
A. To replace nurses with automated systems
B. To eliminate the need for clinical judgment
C. To support safe, efficient, evidence-based patient care
D. To reduce communication among healthcare professionals
Answer: C. To support safe, efficient, evidence-based patient care
Rationale: Health information technology is designed to enhance
patient care by improving access to information, supporting clinical
decision-making, facilitating communication, reducing errors, and
promoting efficient workflows. HIT does not replace nursing
,judgment; rather, it provides information and tools that help nurses
make informed clinical decisions.
Question 2
Which technology is most directly used to document a patient's
assessment findings, nursing interventions, and outcomes?
A. Electronic health record (EHR)
B. Barcode scanner
C. Medication dispensing cabinet
D. Wireless vital-sign monitor
Answer: A. Electronic health record (EHR)
Rationale: The EHR provides a centralized electronic location for
documenting patient assessments, interventions, responses to
treatment, medications, diagnoses, laboratory results, and other
clinical information. Other technologies may contribute data to the
record, but the EHR serves as the primary longitudinal patient record.
Question 3
,A nurse reviews a patient's previous laboratory results before
administering medication. Which EHR capability is the nurse using?
A. Data retrieval
B. Data destruction
C. System authentication
D. Hardware encryption
Answer: A. Data retrieval
Rationale: Data retrieval allows clinicians to access previously
documented patient information. Reviewing laboratory results,
medication history, allergies, vital signs, and previous assessments are
examples of retrieving information from the EHR to support clinical
decision-making.
Question 4
Which term refers to raw facts that have not yet been interpreted?
A. Information
B. Knowledge
C. Wisdom
D. Data
Answer: D. Data
, Rationale: Data are raw, unprocessed facts such as a blood pressure
reading, temperature, or laboratory value. Information results when
data are organized and interpreted. Knowledge develops when
information is understood and applied, while wisdom involves using
knowledge and experience to make appropriate clinical decisions.
Question 5
A nurse recognizes that a patient's temperature of 39.2°C indicates
fever and considers possible causes. This best illustrates the
transformation of:
A. Wisdom into data
B. Data into information
C. Knowledge into hardware
D. Information into encryption
Answer: B. Data into information
Rationale: The temperature reading is raw data. When the nurse
interprets the value as indicating fever, the data become meaningful
information. Further clinical interpretation and integration with other
findings can contribute to knowledge and eventually clinical wisdom.
