Rephase the question

About charting, I come on the floor halfway thru first shift, nurses are super busy doing treatments and meds, so, I am asked to go to the units and chart for them, on their findings, etc all the while I am going on the information the nurses provide for me to chart(written on report) about general findings, ongoing skin issues, etc. Also, LSC and BSP but I try to zip around and listen for that myself too. I dont feel that comfortable with this, but it seems they want me there help out at the end of first shift and charting is the only thing left that has to be done. That and a few tratments which I do too, and chart on my findings. Do I refuse to chart for the other nurses? What is the right thing to do here?
