If you’re a nurse and your job is to take histories, it’s better to take the history in the same way every time, systematically. This minimizes the chance of making mistakes.
Moreover the notes may be wrong, or you may give a different answer this time around. You might give an important detail this time around that you didn’t give the last several times, which actually turns out to be consequential.
It might seem like a waste of your time but it’s really not. Measure twice cut once.
