Roland, don't take this the wrong way, just take it as good advice. KEEP YOUR MOUTH SHUT ABOUT YOUR INTENTIONS!!
Yes, there are nurses, particularly some who instruct in nursing school who have a prejudice against CRNA's. I have seen it first hand. Some of it is jealosy, in that CRNA's make 3-4 times what the average nursing school instructor makes. Some instructors (and nurses) genuinely feel that CRNA's have left the truer faith of nursing. And some are put off by the fact that many, if not most, CRNA's are more conservative politically than the average nurse. There is a reason for that, but this isn't the place to go into it.
Whatever the reason, there are instructors in nursing school who will make your life as tough as they can, and WILL fail you if they can, once they find out about your intention to become a CRNA. Is it right? No. Is it fair? No. Is there anything you can do about it? NO. Just go along.
As to whether they could get into trouble for causing you problems, who will they get into trouble with? Other faculty, who feel the same way they do? I hardly think so. And as pointed out by others, there is a lot of room in clinical grading for "fudging."
Even if they can't get you thrown out, they can make life tougher on you, and who needs that? Is there any harm in keeping your intentions to yourself? Of course not. So, keep it under your hat until you graduate. I know of one (now) CRNA, who upon crossing the stage to receive their college diploma for BSN told the Chairman of the Department of Nursing (while shaking her hand and taking the diploma from her) said "I have taken my first step on the road to becoming a CRNA." Nothing the chair could do about it at that point but fume. Supposedly, the nurse took great pleasure in seeing the stuffed shirt (aren't nearly all Chairpersons of Departments of Nursing pretty full of themselves?) turn three shades of green. If you want to let the school know, graduation is the time. Till then, SHUT UP!
