I doubt
@SWP's back could kill someone when ordering a beer in pigeon Arabic but actually ends up ordering a glass of marbles instead. A nurse on the other hand not having a basic grasp of the language of the country they operate in could be quite dangerous and should be a minimum standard. Which is why it is part of the NNMC’s fitness to practice test (including crazy stuff like qualifications) prior to providing a pin to enable them to work.
Anyone working abroad and not choosing to learn the basics will just end up making life harder on themselves. I can’t describe the troubles I had when I first moved to the USA, I particularly recall one episode when trying to explain that someone was off ill when I said they “were poorly” I then had to explain that they did have enough money to get to work but they were in fact unwell but the damage was done.
