1. Select the best answer. The navigation menu in Google Sites. - MAYBE: may display a subset of the pages that exist in the site; includes all pages that have been created in the site 2. A nursing informatics specialist is speaking to a group of colleagues about the benefits of informatics for the nursing profession. Which benefits would the specialist most likely include? (Select all that Apply) - Improvement in Documentation - Building of evidenced-based knowledge - Use of data for quality control 3. A clinician is reviewing computer systems available for purchase. Which operating system would they expect to find as the most common? - Microsoft windows 4. When using a computer program, a healthcare provider enters a command by painting & clicking. The healthcare provider understands that this action is the result of: - Graphical user interfaces 5. a Wide Area Network (WAN) - Covers a large geographical region 6. Which term describes what normally happens to a computer after a specific period of inactivity - Sleeping 7. Which advantages are associated with the use of cloud computing? Select all that Apply - Allows for sharing file with other users - Provides a backup of files in a location different from where the original document is stored 8. Which computer components are NOT located on the motherboard - Hard Disk drive 9. Which technology includes use of light waves to record data? - Optical disk 10.A processor’s clock speed influences computer cost.
- True 11.A patient connects to their healthcare provider to ask for a medication refill using a secure network connection or “tunnel”. HINT: this data must be encrypted for confidentiality & security reasons. The patient is using: - NOT: intranet - MAYBE: plug in? 12.A clinical is accessing the internet using the following URL- http://www.ahrq.gov/research/findings/evidence-based-reports/index.html. The clinician identifies the "gov" as: - Top-level domain name 13.A healthcare provider is using a web browser and wants to save links to some of the favorite clinical information websites. Which feature would be helpful to use? - Bookmark of favorites 14.A web browser is: - NOT: a server that responds to search engine requests 15.BIOS is considered RAM. - False 16.Briefly (in a sentence or two describe the purpose of a Sandbox environment. - ACTUAL ANSWER: Sandbox is your TEST environment. It would be bad practice to simply modify your published ePortfolio and risk introducing errors into it. Instead, make needed enhancements) to Sandbox first. Once the enhancements are made to Sandbox and they look good and you are comfortable that they don't break anything, then and only then should the same enhancements be made to ePortfollo. - My answer: Your Sandbox serves as your testing environment. It's not advisable to directly modify your published ePortfolio as this could lead to unintended errors. Instead, implement any necessary enhancements in the Sandbox first. Once you've ensured that the enhancements in the Sandbox are satisfactory and don't cause any issues, proceed to apply them to your ePortfolio.
17.The smaller the number of simultaneous bits a processor can handle, the greater its cost. - False 18.One drive is Google's cloud storage solution. - False 19.The focus of Healthcare Informatics is the information and the people who use it. While computers are a necessary tool, they are not the focus of Healthcare Informatics. - True 20.The differentiating feature of a tablet (versus a laptop) is that it has an attached physical keyboard. - False 21.A driver is a hardware component: - False 22.Healthcare professionals need to demonstrate computer fluency in order to be successful in today's healthcare delivery environment. - True 23.In the evolution of Healthcare Information Systems, the earlier focus on process is now shifting towards data. - True 24.One Drive is Microsoft's solution for Cloud Storage. - True 25.Cloud computing requires access to the internet. - True 26.Inframes are small computers with no hard drive limited software, often just providing a Graphical ser Interface (GUI) - False 27.8 bytes are used to represent a character on a keyboard. - False

28.Biosurveillance is enabled by the use of aggregate patient data. - True 29.Volatile memory loses its contents when a computer's power is turned off. - True 30. Computer software licensing - Protects IP 31.Briefly discuss how a particular named computer is able to be located on a network. Which network protocol is used? Be sure to include both static and dynamic addressing in your response, as well as the role of DNS. - Every computer has an IP (Internet protocol) address. It can either be static (always the same IP address) or dynamic (changes every time). TSP is used for data transmission. DNS (domain name system) is used to convert the human read IP address into machine read IP address, this is important for the flow of computers on a network. The IP address is 32 bits. 32.We reviewed 8 different theories in class that form the basis of Informatics. List 3 of these theories, and for each of the 3 briefly describe in a sentence or two their major contribution to Informatics. - According to informatics theory, there exists a systematic evolution from raw data (facts) to organized information and eventually to knowledge and wisdom. This framework holds significant relevance in informatics where data is meticulously examined and interpreted. For instance, in the context of a woman arriving at the emergency room of a hospital, her vital signs such as blood pressure, heart rate, and blood sugar levels are routinely assessed. This data is then augmented with additional contextual information and scrutinized to determine whether the observed values fall within expected norms. Based on nurses' expertise, if any values deviate from the norm, the decision to administer intravenous therapy may be considered. - - An additional perspective is provided by sociotechnical theory, which underscores that not all innovations yield positive outcomes; some may even have adverse effects. For instance, consider the automated phone system in hospitals where callers are directed through a series of prompts before reaching their desired destination. While this process can be frustrating for callers seeking
immediate assistance, it serves to streamline operations for hospital staff who might otherwise be inundated with continuous phone calls. This highlights the significance of evaluating not only the technological aspects but also the practical implications for end-users when implementing new systems. - - Roger's theory delineates various archetypes of individuals observed during periods of change implementation. For instance, there are innovators who readily embrace and adapt to new ideas, contrasting with laggards who exhibit resistance and reluctance towards change. Recognizing these distinct personas is crucial for effective planning and communication strategies when introducing new initiatives.
