The NIH stroke scale it used to identify the severity of stroke like symptoms, and should be scored on the patient's initial presentation, without coaching or duplication. It is important to be consistent when scoring all patients, and identify all deficits.
NIH stroke scale scores patients 0-42, with higher scores indicating increased severity.
Training for appropriate use of the NIH stroke scale is free, at http://nihss-english.trainingcampus.net/
iPhone applications, such as StatCoder, are available and free.

The Himmelfarb librarians have built an extensive reading list for internal medicine sub-specialties, from Cardiology to Infectious Disease. These are a great resource for studying up on both bread and butter as well as zebras.
