I took a Kaplan course, and it helped a lot! They teach you how to answer the questions and will pretty much teach you how to pass in 75 questions. Don't give up you can do it!
I am a new graduate and working my first job as a nurse. I work for a home health agency that visits people with mental illness. I absolutely love it! I knew I wanted to have more time with the people I was helping which is why I love it! There is more to psych nursing than passing meds. I agree that we are their to just listen and teach!
