Cross Contaminated

Today I attempted my first competency on Prosthetic care. I actually went over the procedure over and over again in my head the night before. I didn't pass it because I made a few mistakes and that I had never done it before. I put the partial in the Ziploc bag and then took it to the ultrasonic cleaner and opened the cabinet to get a marker. Well, I had my gloves on the whole time so I cross contaminated. I was so mad at that moment because I knew I failed it. At that point I lost my train of thought and forgot to put the cleaner in the bag as well. I really wanted to get one comp done because I have not had an opportunity to do any! It is a lot of pressure to do something you have never done before and expect to be competent in that. Also I still am not sure how I am supposed to transfer the bag to the ultrasonic cleaner. Gloves or no gloves? I would think gloves. Then I would have to set the bag down somewhere to take off the gloves and open the cabinet to get the marker! This is a glitch that threw off my whole competency! I always think about cross contamination, don't get me wrong, so I get it. My suggestion for anyone doing this comp in the future is to write the name of the patient on the bag before they even get there so you don't have to open any cabinets. Also hope that a FAM person is there so you can have them grab the cleaner? This seems more complicated than it has to be.
