Is anyone interested in applying for an extern? Has any one inquired about them? Most of the hospital allow you to become a nurse extern by shadowing a nurse if you are within one year of graduating with an RN degree. There is one hospital that with take you in as a nurse extern after completing your first semester. I am having a hard time deciding whether or not to apply for the extern position. I believe it would be a positive experience and provide more assistance when it comes to clinicals.
