I saw an obit the other day describing a CNA as “loved her nursing”. The girl aspired to be an RN and her obit said so, but used nursing as a verb. It bugged me until I thought about it for a while. We all “nurse” in the sense of nuturing.
That said, this girl is saying what she does is the same as an RN. If she hasn’t been disciplined by management, she should be and reported to the state BON. The OP notes that she repeatedly does this, so it’s not a mistake.
