What's a MLPN???

I have never even heard of a MLPN but I have heard of someone saying that they had a "advance LPN" but I asked my teacher today & she told me taht because all the schools have to be acceridated that they all pretty much teach the same thing...or program does have a IV cert. in it though.
My teacher was also a LPN for 13 years & then went on to get her masters & said she had never heard of it.

Seems like a title specific to Duke University Health System. Ask them.
