Educational Courses

Just throwing this question out there to see if any nurses might have any suggestions for me! I've worked in the US for 9 months as an RN (previous 8 years as an RN in Canada) and recently left my first US position as it wasn't a good fit for me. I am currently pregnant at the end of my second trimester and have decided it's not the right time to find fulltime work at present just due to the timing. I am really eager to stay active in the nursing community however and would love to find some reputable nursing courses that will keep me busy and allow me to still feel like I'm in "the game" so to speak until the baby comes. Any suggestions for short term, full time courses available in the US? I'd be open to volunteering options as well. Thanks in advance everyone!
