NCLEX/RN registration is various state by state, Nepali PCL can qualify to sit directly for RN exam or state may ask to take some deficient courses. Ask her to take IELTS/TOEFL test at KTM and probably it will help to take/pass NCLEX exam quickly, there are several test preparation classes available and I guess its not too hard to pass the exam. 82% mark does not guarantee US RN ( I meant nepali doctor/professor fail DMV written exam multiple times) . GOOD LUCK.
