1. Which role is primarily responsible for the technical development and maintenance of
electronic health record systems in a clinical setting?
A. Staff Nurse
B. Medical Assistant
C. Nurse Informaticist
D. Patient Advocate
Correct Answer: C
Explanation: The Nurse Informaticist acts as a liaison between clinical practice and
information technology departments to ensure systems meet provider needs. This role
requires a deep understanding of both nursing workflows and technical system
architecture. By maintaining these systems, the informaticist improves patient safety and
clinical documentation accuracy.
2. Which of the following represent significant barriers to the widespread implementation of
telehealth services? (Select all that apply)
A. Reimbursement limitations from insurance providers
,B. Interstate licensure requirements for healthcare professionals
C. Initial high costs of technology and infrastructure
D. Patient and provider resistance to change
E. Poor internet connectivity in rural areas
F. The ability to perform physical assessments remotely
Correct Answer: A, B, C, D, E
Explanation: Barriers such as reimbursement and interstate licensure create legal and
financial hurdles that vary by region and state laws. Rural infrastructure often lacks the
high-speed connectivity required for high-quality video conferencing and data
transmission. While technology is improving, the human factor of resistance remains a
critical obstacle that informatics nurses must address through education.
3. What is the primary goal of the HITECH Act in relation to nursing informatics?
A. To reduce the number of registered nurses in acute care
B. To restrict patient access to their own medical records
C. To eliminate all paper-based charting by the year 2010
D. To promote the adoption and meaningful use of health information technology
Correct Answer: D
Explanation: The HITECH Act was designed to provide financial incentives for healthcare
organizations to implement electronic health records. This legislation emphasizes that
,technology should be used meaningfully to improve patient safety and care coordination. It
also strengthened HIPAA privacy and security protections for electronic health
information.
4. The conceptual framework of Data, Information, Knowledge, and Wisdom (DIKW) is central
to nursing informatics. How is ‘Knowledge’ defined in this hierarchy?
A. Information that is synthesized to identify relationships and patterns
B. Data that has been processed and interpreted
C. Raw facts and symbols with no context
D. The appropriate use of knowledge to manage and solve problems
Correct Answer: A
Explanation: Knowledge is created when information is synthesized so that relationships
and patterns are identified between different data sets. For example, knowing that a
patient’s low potassium level relates to their heart rhythm represents the application of
knowledge. This level of the hierarchy allows nurses to understand the clinical significance
of the data they collect.
5. Which principle of informatics focuses on the ease of use and the effectiveness of a system
for its intended users?
A. Interoperability
B. Usability
C. Scalability
, D. Encapsulation
Correct Answer: B
Explanation: Usability involves assessing how well a user can learn and interact with a
system to achieve specific goals efficiently. A system with high usability reduces cognitive
load on nurses, thereby decreasing the likelihood of errors. Continuous usability testing is
essential during the development and implementation phases of any clinical software.
6. A nurse is using a clinical decision support system (CDSS) that alerts her to a potential drug-
drug interaction. What is the main benefit of this technology?
A. It replaces the nurse’s clinical judgment
B. It increases the time required for medication administration
C. It provides evidence-based information at the point of care
D. It eliminates the need for a pharmacist to review the order
Correct Answer: C
Explanation: Clinical decision support systems are designed to augment, not replace, the
clinical judgment of the healthcare provider. By providing real-time alerts based on patient
data, these systems significantly reduce the risk of adverse drug events. They ensure that
the most current evidence-based practices are integrated into the daily workflow of the
clinician.
