I am so sorry this happened to you, some instructors are idiots. I have heard a lot of negative comments regarding nursing in Nv. I do think there are issues that need attention, but you have time to investigate facilities, search the web, contact the board, and maybe even make a little trip out there. No one call predict your failure unless you are truly an incometent student, if that were so, the school would be doing all in its power to get rid of you, so do not let this instructor's remark stop you from at least seeking answers to your goal.
Some instructors say the meanest things to students, some just really don't think how it sounds, others are sort of jealous of the young nurse with the light in their eyes, seeking their first jobs. Some instructors are real burnouts, and these are the ones who do damage to the students.
I wish you good luck in your quest. I have a daughter out there now, she says it is an awsome place. She doesn't gamble, isn't really interested in the shows, but did go see the Monet on exhibit, has gone to some canyons to see the wild horses, and plans trips to several spots that interest her before she heads back up north. (Just threw that in because people to go to Nv for reasons other than gambling ) Oh yes, there is a large Morman population in NV, seems that was an early church missionary area. The area is growing every month by several thousand people. Rent is high, but not like California, water is a concern and there are strict laws on water usuage. The traffic is horrible at rush hours but that is everywhere. Schools are not keeping up with the influx of students. It is becoming a multicultural area quicker than any other city its size. The opportunity for work is everywhere and age is not as much of an issue as it is other places. I have written you all of this because I found all of this out online. So I know someone committed to a move there will do a better search that I did just fooling around. Good luck again and let us know how it goes.
