I did my nurse training under old style apprenticeship nurse training, before type 1 diabetes, then did BSc, then got T1D, did MSc, which involved working in public health, and still nurse on mountain running races and do home care work for a disabled friend. The single most useful pieces of advice I'd give are ALWAYS trust your instincts and ALWAYS have sweets in your pocket. That will only be a problem if wearing scrubs eg in operating theatres, ICU etc. If in doubt about whether or not you're hypo, and no time to test, then eat sweets. Obviously, if there is time to test, then do so. Remember that you're a member of a team of nurses, all of whome will miss meal breaks at times, so try not to use your extra breaks unless you need. If your insulin pen and blood glucose meter kit are small enough to keep in tunic pocket, then do so, but make sure they can't fall out - safety pins / extra loops might help - get sewing!
