Are you talking about Northern Virginia Community college?
I don't remember a fine arts requirement when I did my undergrad but I had taken classes that qualified. Northern Virginia CC has an articulation agreement with George Mason I believe and I think your best bet would be to look at what type of classes George Mason requires. They actually list out various classes that fulfill the Arts requirement.
Scroll down until you see Arts and the various classes listed.
And I'm guessing it probably doesn't matter what classes you take and I know I've seen nursing students grumble a bit about having to take humanities type courses. I think though there has been work in things like art and music therapy so a course in that might be beneficial later on. Also, one of the best ways to understand a culture is to look at their art, whether that is visual art or musical art. So I think art classes from various cultures can bring some cultural knowledge.
Lastly, feel free to take a class on just a general subject that interests you.
