How do I keep up on my basic nursing knowledge?

I haven't even been a nurse for a year yet and I see that I'm already starting to forget some of my knowledge base that I don't use or see everyday on my floor. What do you seasoned nurses suggest I do to keep up with my nursing knowledge? Reading nursing magazines is not an option for me because I will not keep up with it if I have to read long articles. Do you know of any books/magazines that may have questions or case studies that i can do maybe once a week? I'm open to any suggestions. Thank you.
