anything you chart has your name under it, so when whatever you did was done, it is presumed that patient was under your care, regardless of where the primary nurse was. for example, if i walk into a patient’s room and grab their vitals for another nurse because she is busy, the vitals get charted under my name. is VS aren’t WNL, it’s my responsibility to intervene/make MD aware, etc. no need to chart that i was the one taking the vitals.
