Radiofrequency Identification (RFID) vs. Barcode /Nursing Informatics Reading and Sharing

A primary difference between radiofrequency identification (RFID) and barcode is that RFID has great read range. While the read range for barcode ranges from inches to a few feet, passive ultra-high frequency (UHF) RFID ranges up to 40 feet if readers are fixed or up to 20 feet if readers are handheld. Active RFID has a read range hundreds of feet. Active RFID tags are battery powered and emit a signal while passive RFID tags require activation by a reader.

When displaying patient data for clinical decision making, which type of display tends to slow cognitive processing of the data? — multiple displays on one screen (distracting and slow cognitive processing of data. in most cases, multiple modes of presentation of data provide the best information)

The effective display or patient data for clinical decision making requires that information be rapidly available with minimal cognitive effort. The decision tree is a common presentation with potential options, consequences, and expected outcomes.

Graphs: line graphs, column graphs, and bar charts (compare variables), pie charts and area charts (illustrate the percentage composition of an entity)

Line graph: used to show data over a period of time. is considered the best type of chart for displaying data over time.

Table: use labeled columns and rows to present statistical or alphabetical data in an organized way. although technically not visual aids, they provide a different way of grouping and presenting analyzed data that an analyst wants to communicate to proposal readers.

Pictorial displays: visual indicators, such as colors, may be used to highlight information, such as abnormal lab results, and pictorial displays can be effective.
