NYC specific - There are volunteer things to do that use the nursing license for example: redcross, Medical reserve corp, new york road runners NYRR medical volutneer for marathons. I've worked with and volunteered with both groups, you meet alot of seasoned professionals, get to network and use your skills. You can always lead teaching workshops get a few nursing classmates together put together teaching material topics and approach clinic directors, nursing homes, shelters, offering your services. Ex: diabetes education, medication edu, nutrition. Ah make sure you get permission from the person in charge of the place first. Regular hospital volunteering, some places have special volunteers inside the emergency dept you get to push pts up to thier exams, see trauma units, help out with many things. Offer to tutor your fellow nursing underclassmen at your school while you job search
, help prepare themfor thier clinical practicum whie refreshing your own memory, Be creative there's stuff out there we can do.
Doing things like this helps build your confidence, people skills, and lets you meet others in the profession "networking". I did all the above or some combination of it.
