I had clinical on Thursday and during clinical, I was taking vitals for my assigned patients. When I was getting the vitals machine cleaned and ready to go to my next patient's room, the thermometer fell onto the ground. I picked it up and noticed it had a missing piece on it. I'm was unsure if it was already on there or not, so I look on the patient's floor to see if any piece came off and fell on the ground, but I didn't find anything. I did look at the machine and tested it to make sure it still worked and it did. So now I just remembered that incident and I felt that I should have said something. A nurse did come in after I was done testing the machine, but I guess that distracted me or something. I felt that I should have done something. Any input?
