Informatics and Health Care Technologies
An informatics nurse specialist is working as part of a team that will be developing and
implementing a new client assessment tool. During which phase of the system
development lifecycle would the team be integrating information about workflow
patterns, standard terminology, and recommendations for screen layout from supportive
research? *** Design and build
Explanation:
Mapping out workflow patterns, using standard terminology, and integrating evidence-
based research findings for screen layouts would be accomplished during the design
and build phase of the system development lifecycle. During the analyze and plan
phase, the team would determine the purpose of the technology and the problem to be
solved to establish the need. Testing is done once the technology is designed and built.
Training of the end-users occurs after the system is tested but before it is implemented.
An informatics nurse specialist is working with a team to design a clinical information
system. To ensure system usability, the team would make sure that the language meets
which criterion? Select all that apply. *** Conciseness
Clarity
Familiarity for the user
Explanation:
All language used in a clinical information system should be concise and unambiguous.
Terminology used also must be familiar and meaningful to the end users in the context
of their work; no terms related to computers, technology, HL7, databases, and so forth
should appear in the user interface.
During a recent visit to the clinic, a client tells the nurse, "I've been using my cell phone
to track and record the foods that I eat so that I can better understand if I'm making
healthy food choices." The nurse interprets the client's statement as reflecting which
technology? *** mHealth
Explanation:
The term "mHealth" is used to describe the rapidly evolving use of mobile technologies
to track and improve health outcomes. Nurses, health care providers, other care
providers, and clients are using apps that enable quick and easy access to screens that
provide information and can track progress. Telemedicine refers to the use of
telecommunications technologies to support the delivery of all types of medical,
diagnostic, and treatment-related services, usually by health care providers or nurse
practitioners. Examples include conducting diagnostic tests, monitoring a client's
progress after treatment or therapy, and facilitating access to specialists that are not
located in the same place as the client. Telemedicine involves only remote clinical
services. Patient portals are a web-based tool that promote client engagement.
Pharmacogenomics uses information about a person's genetic makeup, or genome, to
choose the drugs and drug doses that are likely to work best for that particular person.
, Several nurses are discussing their impressions of the newly implemented electronic
health record with an informatics nurse specialist. They say, "There is so much
information on one screen, it hard to tell what we should do first. It's not really clear."
The informatics nurse specialist interprets the comments as reflecting an issue with
which area? *** Usability
Explanation:
The nurses' statement reflects usability. Electronic health records and order-entry
systems are complex. Sometimes the way screens are formatted can be confusing,
making it a real challenge to perform nursing tasks in a way that makes sense.
Interoperability refers to the ability to share data across health care systems.
Optimization refers to strategies to improve processes, maximize effective use, reduce
errors, reduce costs, eliminate workflow inefficiencies, improve clinical decision support,
and improve end-user skills and satisfaction with the system. Security refers to the
ability to keep information private and confidential.
An informatics nurse specialist is engaged in evaluating a clinical information system. At
which time would the nurse specialist anticipate the need to obtain help from a
statistician? *** When determining the data collection method
Explanation:
It would be appropriate to secure the help of a statistician when the informatics nurse
specialist is determining the data collection method and sample size. Securing help
during the literature search would be too early. When preparing how to display the data
or just prior to documenting the outcome evaluation would be too late. The nurse
specialist would have had to analyze the data with the help of a statistician before
displaying it.
An informatics nurse specialist is working on a team that is considering a new
technological system for the facility. Which aspect would be most important for the team
to do as the first step? *** Determine the need or problem to be solved
Explanation:
Before considering the use of any new technology or an update to the system, analysis
and planning must occur. This involves determining the need for the technology or
update or identifying the problem to be solved. Once that step is completed, then design
(such as using standard terminology), testing and training would occur.
An informatics nurse is teaching a clinic staff about a newly implemented patient portal
being used. The informatics nurse determines that the teaching was effective when the
staff identify which aspect as being the focus of this technology? *** Greater client
engagement
