I'm with Shelby P. Go to an accelerated nursing program. You get into this because you already have a degree. Then when you graduate take your NCLEX exam. This is an exam to get your RN License. Then apply for a master's program. Hope it works out for you for the best, good luck.
I don't think it is that big of deal as long as the physician didn't touch the end that touched the patient. That happens a lot in trauma, and I have seen it happen in the different hospitals that I travel to. As long as the sponge stays sterile shouldn't matter. Hope this helps with your anxiety. Have a good day!
