I took the NCLEX for the first time last week, and I encountered the same questions you had, first question SATA , then drugs , then this topic about nurses in conference etc., but I had 230 question before the computer shut down . I think I also failed because I tried the PVT trick and leads me to the CC page.
I do all the studying for months Kaplan, NCSBN , Nclex 4000 and all the tips and hints from this site. It seems I didn't study at all . My family knows I'm still waiting for the result since there is no quick result in California.
