Question 1
Which of the following best defines nursing informatics?
A) The use of technology to order medications and view laboratory
results
B) The specialty that integrates nursing science with multiple
information and analytical sciences to identify, define, manage, and
communicate data, information, knowledge, and wisdom in nursing
practice
C) The process of entering patient data into an electronic health record
for billing purposes
D) The application of computer hardware and software to manage
hospital admissions and discharges
Answer: B
Explanation: Nursing informatics is a formal specialty recognized by the
American Nurses Association. It is not merely about using computers or
entering data; it is a scientific discipline that combines nursing science,
information science, and cognitive science to manage and communicate

the data, information, knowledge, and wisdom that underpin nursing
practice. Option A is too narrow, option C focuses on administrative
functions, and option D omits the analytical and knowledge
components.
Question 2
A nurse is using a clinical decision support system (CDSS). Which of the
following is the primary purpose of this system?
A) To replace the nurse's clinical judgment entirely
B) To provide alerts, reminders, and evidence-based recommendations
at the point of care
C) To process insurance claims and billing information
D) To schedule staff shifts and allocate resources
Answer: B
Explanation: A clinical decision support system is designed to assist
healthcare providers in making clinical decisions. It provides real-time,
patient-specific information, such as drug-drug interaction alerts,
preventive care reminders, and diagnostic support. It is a tool to
augment, not replace, clinical judgment. Options A, C, and D describe
functions that are not the primary purpose of CDSS.
Question 3
Which of the following is an example of secondary data use in a
healthcare information system?
,3|Page
A) A nurse documenting a patient's blood pressure during a morning
assessment
B) A physician ordering a medication based on a patient's current lab
values
C) A hospital administrator analyzing aggregated data to identify trends
in infection rates
D) A patient viewing their own laboratory results through a patient
portal
Answer: C
Explanation: Secondary data use refers to the reuse of clinical data for
purposes other than the direct care of the individual patient. While
primary use involves direct patient care (options A and B), secondary
uses include quality improvement, research, public health surveillance,
and administrative planning. Option C represents a secondary use, while
option D is a patient engagement function, not a secondary data use
per se.
Question 4
A nurse notices that a patient's electronic health record (EHR) contains
outdated allergy information. What is the most appropriate action?
A) Ignore the information as it is likely a minor error
B) Delete the outdated allergy entry without further investigation
C) Update the allergy list based on a new patient interview and
documented evidence, following the facility's policy for correction

D) Notify the information technology department to correct the record
Answer: C
Explanation: Maintaining accurate and current data in the EHR is a
fundamental responsibility of the nurse. Outdated or erroneous data
must be corrected according to established protocols. The process
typically involves making a new entry that supersedes the old one,
leaving an audit trail. Simply deleting the entry is often not permitted,
and ignoring it compromises patient safety. While the IT department
manages the system, the clinical content is the responsibility of the
clinical user.
Question 5
Which term describes the ability of different information systems to
exchange data and use the information that has been exchanged?
A) Standardization
B) Interoperability
C) Integration
D) Digitization
Answer: B
Explanation: Interoperability is the key concept referring to the capacity
of different systems, such as an EHR and a laboratory system, to
communicate, exchange data, and interpret the shared data. While
standardization (A) enables interoperability, and integration (C) is a
