Hi- I'm currently half way through nursing school and also work as a CNA in hospitals. We're finishing up learning about central lines/PICCs etc., and I know that you're not supposed to use an arm with a PICC to take the BP, or so I was taught and have always though. But, I'm working with a nurse tonight who said you could take the BP in the arm as long as it's below the PICC, so in the forearm- is this allowed? I've heard differing opinions- what's the right answer?
