| Actual Q&A with Rationale (NRS450 Exam 2) |
Grand Canyon University
1. Which of the following describes the primary focus of the Health Information Technology
for Economic and Clinical Health (HITECH) Act?
A. Establishing strict protocols for manual charting in rural hospitals.
B. Promoting the adoption and meaningful use of health information technology.
C. Limiting the access of nurses to electronic health records to ensure privacy.
D. Providing federal funding for nursing education in informatics programs.
Correct Answer: B
Explanation: The HITECH Act was enacted to stimulate the adoption of electronic health
records (EHR) and supporting technology in the United States. It provides financial
incentives for demonstrating ‘meaningful use’ of these technologies to improve care
quality. The act also strengthens HIPAA rules regarding data privacy and security
requirements.
2. A nurse is explaining the difference between data and information to a student. Which
example best represents ‘information’?
A. A heart rate of 110 beats per minute.
B. A list of patient weights for a unit.
,C. The raw number 98.6.
D. A heart rate of 110 beats per minute recorded as tachycardia for a resting patient.
Correct Answer: D
Explanation: Information is data that has been interpreted and given context or meaning
within a specific clinical situation. In this case, labeling a specific heart rate as tachycardia
provides clinical significance that the raw number alone lacks. This transition from data to
information is a core concept of the DIKW (Data, Information, Knowledge, Wisdom)
framework used in nursing informatics.
3. Which clinical decision support (CDS) tool would most likely prevent a medication error at
the point of care?
A. An educational seminar on safe insulin administration protocols.
B. A monthly report on medication variance sent to the unit manager.
C. A printed pharmacological reference manual located at the nurse’s station.
D. An automated alert for a drug-drug interaction during order entry.
Correct Answer: D
Explanation: Automated alerts serve as real-time clinical decision support by providing
immediate feedback to the prescriber or nurse. These tools are designed to catch potential
errors before they reach the patient, such as allergies or incompatible medications. By
integrating this intelligence into the workflow, the system enhances patient safety and
reduces cognitive load.
,4. Select all that apply: Which of the following are considered primary goals of Meaningful
Use (MU) of electronic health records?
A. Improve quality, safety, and efficiency of patient care.
B. Engage patients and families in their own healthcare.
C. Improve care coordination across different facilities.
D. Ensure adequate privacy and security protections for personal health information.
E. Reduce the number of nurses required to staff a clinical unit.
F. Improve population and public health outcomes.
Correct Answer: A, B, C, D, F
Explanation: Meaningful Use focuses on five main health outcomes policy priorities,
including safety, patient engagement, and coordination. Reducing nursing staff is not a goal
of MU; informatics aims to support nursing practice rather than replace it. These objectives
were designed to be implemented in stages to ensure systemic improvements in the
healthcare delivery model.
5. When discussing interoperability, what is the significance of using a standardized nursing
terminology like SNOMED CT?
A. It prevents patients from accessing their own electronic health records.
B. It allows different computer systems to exchange data and use the information
consistently.
, C. It reduces the cost of electronic health record software licenses.
D. It eliminates the need for nurses to document their assessment findings.
Correct Answer: B
Explanation: Standardized terminologies ensure that clinical data has a shared meaning
across various platforms and providers. This semantic interoperability is crucial for
tracking patient outcomes and conducting large-scale research. Without standardized
terms, the data collected in one system might be misinterpreted when viewed in another.
6. A nurse is using a telehealth platform to monitor a patient with chronic heart failure.
Which action represents the use of ‘wisdom’ in the DIKW framework?
A. Adjusting the patient’s care plan to include immediate diuretics based on their weight
gain and symptoms.
B. Recognizing that the patient’s blood pressure is elevated compared to their baseline.
C. Documenting the blood pressure in the patient’s electronic portal.
D. Reading a blood pressure value of 160/95 mmHg.
Correct Answer: A
Explanation: Wisdom is the appropriate application of knowledge to manage and solve
human problems. It involves using clinical judgment and experience to determine the best
course of action for a specific patient. In this scenario, integrating data, information, and
knowledge to change a care plan exemplifies the highest level of the DIKW hierarchy.
