If you're a registered nurse who wants to maximize earning potential and qualify for better nursing jobs, consider earning a Bachelor of Science in Nursing (BSN). There are many RN to BSN programs available online that allow you to advance at your own pace while continuing to work in your current position. Many RN to BSN degree programs even offer college credit for skills learned on the job. Median earnings of RNs in 2006 topped $57,000. Adding a BSN degree to your resume could help you earn even more.
