Document. Document. Document. It does not matter what the nurse before you did or did not see (well kind of). Things can change for the worse or better and you should chart what is right in front of you and how you perceive it using your best judgement. I've seen nurses simply chart what the nurse before them charted without even assessing the patient. Other nurses make mistakes, we are all human. But it is best to not second guess ourselves just because we see or don't see something different. That alone could save a person's life.
