the nurse advised that i go to a hospital....that seems like the better translation...
Closer to the Esperanto sentence, yes, but would you really say that?
I would but I'm Mexican american so i guess maybe that colors my speech
In RL I'd probably say "suggested" and drop a should in there, somewhere.
I would, and I'm a native English speaker (Canadian).
flegi (“to nurse”) + -isto (“professional”)
