To add to what Abby and the contributors in the other question are saying, check with your college's student job center if there is one. Many colleges do have one as a resource for graduating seniors to help find jobs, help with mock interviews, resume and cover letter recommendations, etc. There are also resources online that help with the same things if your college doesn't have a dedicated student job center.
For your field of Nursing there are opportunities as local hospitals. If you're interested in that type of job you can research and contact hospitals in your area for job opening that may fit you.
There are also many online job boards which can help you find a career. Below is one example of www.Indeed.com with a simple search for nursing. You can research and narrow done by your location that you want, years of experience, job responsibility etc.
Most of the friends I have that became RNs did some sort of in-hospital training or rotation as part of their classes. If you did something similar then those businesses would be a good place to start as you already have a foot in the door with them, and they know your work ethic.
