When I had similar questions I looked online, discovering a bewildering array of regulations and requirements for MAs. depending on which state you live in. Your state Board of Nursing will most likely not have the info you seek since they are limited to the practice of nursing. Your state Medical Board may be a better source. I know that most MAs are trained in phlebotomy, so it may be legal to start the IV but not add meds to the infusion or other restrictions. Sorry we couldn't answer with more specificity.
