Interview apparel ?

I vote for business casual unless you are in New York where they tend to dress up more elaborately. Depending on where you live, there is probably a shortage of jobs out there - don't diminish your chances by under-dressing.

I would never wear scrubs to an interview. In the past I have worn a business-like pant suit or a very conservative low key dress. Always clean, neat and modern looking but nothing flashy. I was told once to dress how you want to be paid. If you dress like a bum they might think you have low standards. I cant say for sure but in some cases it might make a difference whether they offer you the high end or the low end of the range that they can offer you.
I once saw a nurse show up for an interview for a DON position in LTC wearing a cotton blouse with dress pants and WHITE SNEAKERS! This just blew my mind. Needless to say she did not get the job even though she had years of DON experience and they were desperate.

dress is important as is personal hygiene, nails, hair teeth must be clean, nails trimmed , hair appropriately combed etc, once had an applicant come in hair all over the place, nails chipped and dirty, teeth could have been brushed... made a terrible impression and despite good references, we didn't hire her!

I wore scrubs to an interview once. I had to schedule the interview after my shift working the floor and there was no time to change. The woman interviewing said she loved my scrub jacket which I had made myself! I got the job ---didn't have to wear scrubs any more. I interviewed with someone who was in her late 60's...she had her belly hanging out of her shirt and swore a blue streak. Not someone I would want to work for! It goes both ways. Be professionally dressed.
