NSG320 COMPREHENSIVE NURSING
INFORMATICS AND RESEARCH EXAM
QUESTIONS AND ANSWERS
1. A nurse manager is evaluating the effectiveness of a new electronic medication
administration record (eMAR) system. Which metric best represents ‘Information’ in the
DIKW (Data, Information, Knowledge, Wisdom) hierarchy?
A. The number of medication errors recorded in the last month.
B. A single blood glucose reading of 120 mg/dL.
C. The trend of decreasing medication errors since the system implementation.
D. The clinical protocol for treating hypoglycemia.
Answer: C
Conceptual Explanation: Information is data that has been processed or organized to
provide meaning, such as trends or comparisons.
,2. When constructing a PICO question, a researcher defines the ‘I’ as ‘the use of robotic-
assisted therapy.’ Which of the following would be an appropriate ‘C’ (Comparison) in a high-
level research study?
A. The duration of the robotic therapy session.
B. Standard manual physical therapy.
C. Patient satisfaction scores.
D. Reduction in hospital length of stay.
Answer: B
Conceptual Explanation: The Comparison (C) represents the alternative to the
intervention (I), which in this case is the standard care (manual therapy).
3. A nurse is participating in a usability test for a new clinical decision support tool. The nurse
is asked to ‘think aloud’ while navigating the interface. This method primarily evaluates:
A. The nurse’s cognitive load and mental model.
B. System interoperability.
C. The speed of the local area network.
D. Data encryption standards.
Answer: A
Conceptual Explanation: The think-aloud method is a usability technique used to
understand how a user perceives and interacts with a system’s interface.
, 4. According to the HIPAA Security Rule, which of the following is considered a technical
safeguard?
A. Locked filing cabinets for paper records.
B. Workforce training programs.
C. Facility access controls.
D. Encryption and decryption of electronic PHI.
Answer: D
Conceptual Explanation: Technical safeguards involve the technology and the policy and
procedures for its use that protect electronic PHI and control access to it.
5. In a quantitative study, a researcher reports a p-value of 0.02. If the alpha level was set at
0.05, what is the correct interpretation?
A. The null hypothesis is rejected.
B. The findings are not statistically significant.
C. The null hypothesis is accepted.
D. The intervention had no clinical effect.
Answer: A
Conceptual Explanation: A p-value less than the alpha level (0.05) indicates statistical
significance, leading the researcher to reject the null hypothesis.
