You are right trust your instinct you have been gone longer than you worked as an RN if you feel you need to orient then you need to orient..Don't do anything that will risk your license.. You were honest about your time away let them deal with it and if they have a problem just goes to show you they are more interested in having you out there than having you practice safely and comfortably and that is somewhere that may not be where you want to work.. Good Luck and at therisk of sounding cliche everything happens for a reason.
