I adore chemistry, so I am prejudiced.
Here's why I think it's helpful:
1. As Hotflashn said, it will help you understand other courses better: A&P in particular and Pharm in nursing school. Right now, I am taking microbiology, and understanding chemistry is helping me a lot; I feel like I get more out of the micro class. Overall, you will understand the processes of the human body better if you understand the chemistry that's going on in it.
2. Chemistry teaches you to think in a very orderly, step-by-step way. This will help you with critical thinking skills, and it also teaches you to instinctively know when an answer just isn't "right", even if if you're not sure why yet. The problem-solving approaches and methods are definitely transferable skills -- and important ones.
3. Chemistry emphasizes the method of dimensional analysis. I'm not in nursing school yet, but other nursing students have told me that being comfortable with dimensional analysis is a big help with medication calculations in NS.
But that's advice from someone who is fond of saying, "Chemistry is everything!".
