Abstract: Computer-implemented methods and applications for providing a user with educational guidance for peripheral IV therapy are described. In one example, a computer-implemented method for providing educational guidance for peripheral IV therapy includes displaying, on a display of a machine, a main menu including a plurality of person profiles; machine-prompting the user to select one person profile of the plurality of person profiles; machine-prompting the user to select an insertion site from a plurality of insertion sites on a person's appendage based on the selected person profile; machine-prompting the user to select a first product category from a plurality of product categories; and machine-prompting the user to select a first product of a plurality of products within the first product category, the first product being a most appropriate product of the plurality of products based at least in part on the selected person profile.
