As an aide, it isn't within your scope of practice to do many of the things you listed. Perhaps you could be trained at your hospital to do phlebotomy or be a telemetry tech (read monitors), but only an RN can do patient assessments, and only RN's & some LPN's can hang IV's. The best way to learn a lot in your current position is to observe the nurses a lot, & ask if you can watch while they do certain procedures, etc.
