This one should accept the answer with or without article.
This is the name of a mildly interesting Thai horror film (but it's Nurses- plural), though I'm almost certain that's not what this is referring to since it's really not popular.
So is this "a nurse that is sick" or just "a nurse"?
Sick nurse doesn't even get a hit on Wikipedia, except for a Thai horror movie.
쩐다, 쩔어, "dictionary form" (though it's slang or something I have yet to find it in one) 쩔다 -- nobody around here knows this, and it may be as dated as I am . . .
"sick 5 [informal] Excellent."
