Grand Canyon University
1. According to the American Nurses Association (ANA), how is nursing informatics defined?
A. The use of computers to track patient vital signs and medication administration records.
B. A specialty that integrates nursing science, computer science, and information science to
manage and communicate data, information, knowledge, and wisdom in nursing practice.
C. The management of hospital hardware and software systems by registered nurses.
D. A method of documenting nursing care that relies solely on electronic medical records.
Correct Answer: B
Explanation: The ANA definition emphasizes the integration of three distinct sciences to
support nursing practice. This integration is designed to manage data and turn it into
wisdom. It helps nurses communicate information more effectively across the healthcare
continuum.
2. A nurse is reviewing the DIKW hierarchy. Which of the following examples best represents
‘Information’?
A. A heart rate of 120 beats per minute.
B. Recognizing that a heart rate of 120 bpm is tachycardic for an adult at rest.
,C. Applying clinical experience to determine that tachycardia is related to the patient’s
recent surgery.
D. Integrating multiple patient datasets to create a long-term care plan.
Correct Answer: B
Explanation: Information is data that has been processed and given meaning within a
context. In this case, ‘120 bpm’ is raw data, while the recognition that it is ‘tachycardic’
provides necessary context. This transition represents the second level of the DIKW model
used in informatics.
3. Under HIPAA, which of the following are considered Protected Health Information (PHI)
identifiers? (Select All That Apply)
A. Social Security Numbers
B. Full-face photographic images
C. Vehicle identifiers and serial numbers, including license plate numbers
D. Patient initials used in a clinical research paper
E. Geographic subdivisions smaller than a state (e.g., street address)
F. The patient’s preferred flavor of gelatin
Correct Answer: ABCE
Explanation: HIPAA identifies 18 specific identifiers that must be protected to maintain
patient privacy. This includes everything from physical addresses to photographic images
, and serial numbers. The patient’s preference for gelatin flavor is generally not considered a
protected identifier unless linked to specific medical records.
4. The nurse uses a Clinical Decision Support System (CDSS) to cross-check medication
interactions. What is the primary goal of this technology?
A. To enhance clinical performance and improve patient safety by providing evidence-
based information.
B. To reduce the time nurses spend at the bedside by automating tasks.
C. To replace the nurse’s clinical judgment with automated algorithms.
D. To ensure that the hospital meets the minimum billing requirements for Medicare.
Correct Answer: A
Explanation: CDSS tools are designed to assist healthcare providers in making informed
clinical decisions. They use patient data and evidence-based knowledge to trigger alerts
regarding safety issues like drug interactions. Ultimately, these systems aim to improve
patient outcomes rather than replacing the nurse’s expertise.
5. Which initiative was formed to bridge the gap between nursing practice and information
technology by defining informatics competencies?
A. The TIGER Initiative (Technology Informatics Guiding Education Reform)
B. QSEN (Quality and Safety Education for Nurses)
C. The HITECH Act
