Use of English language in hospitals

[harm_less]

I have always assumed that immigrant nurses have to pass an English language test before they are employed.  Is that not the case?

My sister has complained of additional workload created by her having to train immigrant nurses over the past couple of years. She is well used to 'retraining' the young nurses fresh out of polytech but the idiosyncrasies added by the likes of Asian immigrants whose default answer is yes, because it is less likely to result in negative connotations, or those who struggle with identifying gender because their native tongue doesn't differentiate in this.

"Is Mr Smith ready for surgery?"
"Yes she is."
"Do we need a chaperone for him/her?"
"Pardon?"
All made the more complex by recent moves by those that want to avoid being gender classified by using non-gender pronouns.

"Have you cannulated Mrs Jones?"
"Yes"
"Mrs Smith hasn't got an IV line in yet"
"Pardon?"

What could possibly go wrong?
