yeah she does that, she wont despawn even if you teleport all the way across the map, plantara does though when she leaves the jungle, so if you set up a pylon network to the nurse and to a base by your arena then she will try to chase you but if you are fast enough you can go back to the jungle and she will come back, i would recommend this strategy with queen bee too so that your nurse is never in danger and you can always heal
