1. Which of the following are primary components of a Clinical Decision Support System
(CDSS)? (Select All That Apply)
A. Knowledge base
B. Reasoning engine
C. Communication mechanism
D. Hardware power supply
E. User interface
F. Physical filing cabinet
Correct Answer: A, B, C, E
Rationale: A Clinical Decision Support System (CDSS) primarily consists of a knowledge
base, an inference or reasoning engine, and a communication mechanism with a user
interface. The knowledge base contains the compiled medical information and rules, while
the reasoning engine applies these rules to patient-specific data. The communication
mechanism allows the nurse or clinician to interact with the system to receive alerts or
,recommendations. Physical filing cabinets and hardware power supplies are not
considered core functional components of the CDSS software logic.
2. The nurse understands that ‘Information Literacy’ is best defined as:
A. The ability to use a computer keyboard and mouse efficiently.
B. The ability to repair medical equipment in the clinical setting.
C. Knowledge of complex coding languages like SQL or Python.
D. The capacity to recognize when information is needed and to locate, evaluate, and use it
effectively.
Correct Answer: D
Rationale: Information literacy involves a high-level cognitive skill set that allows a nurse
to identify a gap in knowledge and find the necessary data to fill it. It encompasses the
evaluation of the credibility of sources, particularly in the context of evidence-based
practice. This skill is essential for lifelong learning and professional development in the
rapidly evolving field of nursing informatics.
3. Which of the following is a major goal of the TIGER (Technology Informatics Guiding
Education Reform) initiative?
A. To eliminate all paper-based records by the year 2010.
B. To reduce the cost of healthcare by outsourcing nursing jobs.
C. To make nursing informatics a core competency for all healthcare professionals.
, D. To develop a single global EHR system for all countries.
Correct Answer: C
Rationale: The TIGER initiative was established to integrate informatics into nursing
education and practice to provide safer, high-quality patient care. It focuses on ensuring
that all nurses are computer literate, information literate, and capable of managing
information effectively. This initiative emphasizes that technology is a tool to support
clinical judgment rather than replace it.
4. The Health Insurance Portability and Accountability Act (HIPAA) Security Rule specifically
governs which type of information?
A. Oral communications between providers.
B. Paper records kept in a locked office.
C. Electronic Protected Health Information (ePHI).
D. Patient demographics shared on social media by the patient.
Correct Answer: C
Rationale: The HIPAA Security Rule specifically addresses the protection of health
information that is held or transferred in electronic form. It sets national standards for
administrative, physical, and technical safeguards to ensure the confidentiality, integrity,
and security of ePHI. While the Privacy Rule covers all forms of PHI, the Security Rule is
focused on the digital environment.
