"Anki is a spaced repetition system (SRS). It helps you remember things by intelligently scheduling flashcards, so that you can learn a lot of information with the minimum amount of effort." Free, open-source, multi-platform desktop application.
Import a list of Questions / Answers (or front and back) for flashcards and then print them out. Instrutors could make these available for students. Or, student could make them available for each other.
I really like the use of flashcards especially for undergraduate students. An assignment can be designed in which each student is to do one flashcard for each lecture. As a faculty member, I can collect all of the flash cards and utilize them in class as a learning tool with students.
This site has over 18,000,000 sets of flash cards posted. Over 2,000 are tagged with "nursing". The site is well organized, providing easy access to card sets for specific topics.
