What did you learn besides license-required professional nursing care? You learned disease processes, medications, diagnostic tests, life span health & psychsoc issues. You learned about mental illness, public health, preventative care, health education and more. You have experience interacting with people in times of crisis, vulnerability, anxiety, etc. You spent time in different health care facilities, directly interacting with health care personnel. Even without a license or professional clinical practice, this kind of knowledge and experience is valuable and in demand in various areas. Having a bachelor's degree in addition that specific background can definitely help open doors to certain jobs.
Since nursing is related to most any aspect of health and well-being, you can look for health-related jobs that require/prefer a bachelor's degree in a "related field." I suggest checking local hospital job boards, health department job boards (county, state), academic medical centers, & universities. Also, explore the listings at any major employers in your area as they might have a department involved in something health-related that you weren't aware of, such a niche medical supply manufacturing branch or an internal employee health department.
Do some exploratory job listing searches on-line using key words like "medical" "health" "entry-level" "bachelor's required" etc. From what you find, start identifying other key words & phrases that might help find other "hidden" job listings... words & phrases such as clinical research coordinator, health information managment, reimbursement, and more. Other areas/businesses/key words to check out insurance companies, medical suppliers, manufacturers, health information technology, quality improvement, publishing, professional associations, coding, abstracting, community health and more.
One thing is to not let yourself get too distracted by all the RN job listings you may come across in your searches and end up spending too much time thinking "if only".
Finally, even if there aren't any open job listings that you are currently qualified for, you can still give a company/department manager/etc a call and ask more about a certain job, their line of business, recommendations for getting into their field, etc just for information. It could be a fruitless effort, but it's also possible that you'd learn more about other related possibilities and directions to explore!
Best wishes to you!
