1) Get a PDF copy of your official protocols. There are apps you can use, but I always felt more comfortable being able to pull up the actual guidelines as laid out by the state, and knowing they are up to date. Nice to double-check dosing when on the way to a call or whatever.
2) Google Translate! It’s free and works surprisingly well. I can manage Spanish well enough, but we had a lot of Mandarin-only, Russian-only, etc, patients. You can download the languages you use most often and it will work without using data.
