In the medical field, professionals are expected to evaluate knowledge deficits and provide teaching. This especially applies to RNs. In Louisiana it is a requirement for RNs. We never assume someone understands no matter how simple the information may seem. A professor in my nursing school taught us that to assume will make an a$$ out of you and me. That stuck. I assess for knowledge, teach and evaluate for understanding and re-teach if needed and re-evaluate. If I don't do that and something happens I am liable. The teaching is also documented as well as understanding by the client.
I understand all that....but to me informed consent means informed consent. Read the paperwork...ask questions when you are reading. That is expected. Of course when questions are asked an RN or MD answers them. But it does not require continuous reinforcing......does it? I'm beyond sure that the staff told family that Jahi was not to eat. How many times does it require being said? Would it have made a difference? Some how I doubt it. Just glad I'm retired.
