Yikes, that is somewhat of a predicament... Most places want at least one year of experience (especially PRN) simply because you truly don't develop a "rhythm" to your own nursing skills until around that 12-18 month mark. PRN is especially hard because you have shorter orientation and are expected to know what to do and how to do things from the go. You also need time to understand the systemic process that you are treating and why you are treating them a certain way. My recommendation would be try and get some overtime at your current job instead of taking on a PRN position. That way you can have more income and gain more skills and knowledge in the current position your in without becoming overwhelmed. Longevity and unique skill sets are what make certain nurses more valuable than others.
