Can another nurse chart on behalf of you?

My DON rewrote a nurse's entry and wrote in the entry that she was rewriting it. I thought it was irregular at the time; we other nurses talked about it, but nobody would say anything to her. In that particular instance, the DON was present when the occurrence took place, so she could have made an entry anyway. But what made it wrong, in my mind's eye, was that the original entry left the chart for parts unknown. I couldn't understand why the DON would make the statement she did and remove the other entry.

Why can't you say 'Phone call received from RN Jones. She stated that pts dressing was changed today at 0300?'
