i sat for the nclex two days ago and stopped at 75 as well. mine was just like yours, and it seemed like i was taking a PHARM test. i am honestly weak at meds but i guess i expected for the worst so i could say i came in prepared for the meds part. i also had diet and nutrition. and i realized just now, those aren't low level questions. they come in "coma-coma" and i believe it's supposed to make you critically think which among the given are under whatever food category, or if it's safe for the client to take, and their diagnosis is also something to think about when answering these diet questions, correct? but just that's my opinion.
anyway. i too had the infamous pop-up everyone is getting, and i'm keeping my fingers crossed. try it, it'll help you feel less anxious:) goodluck and congrats in advance! :)
