Nursing informatics end of chapter questions with verified answers 2024 A nurse informaticist is using the steps of the SDLC to design a new system for home health care documentation. The nurse analyzes the old system and develops plans for the new system. What step of this process will the nurse take next? A. Testing B. Designing C.Implementing D. Evaluating - Correct Answer b. The SDLC focuses on the areas of Analyze and Plan, Design and Build, Test, Train, Implement, Maintain, and Evaluate. After analyzing and planning the new system, the nurse would move on to the design step in which the basic design of the new system is developed. The nurse would then test the system, train employees, and implement, maintain, and evaluate the new system in that order. After instituting a new system for recording patient data, a nurse evaluates the "usability" of the system. Which actions will the nurse include in this step? Select all that apply. A. Checking that the screens are formatted to allow for ease of data entry B. Reordering the screen sequencing to maximize effective use of the system C. Ensuring that the computers can be used by specified users effectively D. Checking that the system is intuitive and supportive of nurses E. Improving end-user skills and satisfaction with the new system F. Ensuring patient data is shareable across health care systems - Correct Answer a, c, d. Usability refers to the extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency, and satisfaction in a specified context of use. Checking that screens are formatted to allow ease of data entry, ensuring that computers can be used by specified users effectively, and checking that the system is intuitive and supportive of nurses are all tasks related to the "usability" of the system. Maximizing screen sequencing and improving end-user skills and satisfaction with the new system refer to optimization. The ability to share patient data across health care systems is termed interoperability. A nurse is using informatics technology to determine which patients may be at risk for readmission. What term best describes this type of analytic? A. Data visualization B. Predictive analytics C. Big data D. Data recall - Correct Answer b. Predictive analytics uses statistical techniques to analyze current and historical facts to make predictions about future or otherwise unknown events.
