During change of shift, Per our policy myself and the oncoming day shift nurse were checking duragesic patch placement on our residents. we entered resident A's room and she proceeded to look for resident a's patch. I had just seen it earlier on in the shift when i counted off with the 3-11 shift nurse. I reached down to help her look for the patch, and her face got red and she grabbed my arm really hard, dug her nails in and pushed my arm away from the resident, and stated "why do you always have to be so uptight?!?!" I almost started to cry, and was really embarrassed by the whole incident. Do you think that I'm reading too much into this?
