Well.. I dunno about the RN part but some traveling suggestions.. before you leave.. make sure you have an emergency kit that you keep in there at all times!! I always make my friends/family pack one, and one year it helped
My E. Kit:
Road Flare
60min calling card
band-aids/antibiotic
biggest can of Fix-A-Flat you can buy (This is your home you dont wanna drive on a flat).
Mace
Emergency Info Card (contact number, medical allergies, etc).
Batteries
Flashlight
Glow Sticks (its halloween, best time to buy some, these things work great when you pull over at night and get out to walk around, snap one and hang onto it. Drivers, etc will see you).
Well Im done

Everyone always laughed at me but then my grandmother went on a trip.. they broke down in the country (im talkin SERIOUS country.. house every 7miles or so) and she flagged down a care with a glow stick
