Because several disciplines support the foundation of informatics nursing, it is important for the informatics nurse to understand that:
- A. informatics nursing differs from other disciplines, as it focuses on supporting the process of obtaining data.
- B. informatics nursing uses the concepts, tools, and methods of various disciplines to facilitate nursing process.
- C. information technology and nursing technology are synonymous, as they have the same goal.
- D. the boundaries between the various disciplines are clearly defined.
Correct Answer: B
Rationale: Informatics nursing integrates concepts, tools, and methods from multiple disciplines (e.g., computer science, information science, and nursing) to support the nursing process, rather than focusing solely on data collection or having synonymous goals with IT.
In project management, the critical path is best described as a series of activities that:
- A. includes the path with the most slack or float.
- B. indicates the earliest possible time a project can be completed.
- C. is scheduled for the next current phase of the process.
- D. shows the shortest path through the network diagram.
Correct Answer: B
Rationale: The critical path is the sequence of activities that determines the earliest possible completion time for a project, as any delay in these activities will delay the project.
The informatics nurse is working on a chart to demonstrate the increasing incidence of obesity in the patient population at a health clinic. The data will represent patients who are of normal weight, overweight, obese, and morbidly obese, and it will include the percentage of the total population for each group. This type of data is most effectively represented by a:
- A. bar chart.
- B. column chart.
- C. line chart.
- D. pie chart.
Correct Answer: D
Rationale: A pie chart is ideal for showing the proportion of each category (e.g., normal weight, obese) as a percentage of the total population.
Adherence to a standardized nursing language will lead to:
- A. a barrier in national interoperability.
- B. a larger database of interventions.
- C. improved evaluation of nursing outcomes.
- D. increased nursing competencies.
Correct Answer: C
Rationale: Standardized nursing language ensures consistency in documentation, which facilitates data comparison and analysis, leading to improved evaluation of nursing outcomes.
Adult learners most effectively learn about a new clinical information system when the instructor:
- A. assumes that the learner knows nothing about the system.
- B. begins the formal training as early as possible in the implementation process.
- C. emphasizes the technical specifications of the structure of the system.
- D. encourages the learner to use previous experience to interpret new learning.
Correct Answer: D
Rationale: Adult learners benefit from leveraging prior experience to contextualize new information, making learning more relevant and effective.
