I think it's a bad idea to take a year-long vacation. You may no longer be eligible for new grad positions when you start applying to jobs. The longer you wait after graduation, the harder it is to find a job. A handful of people from my graduating class have not yet found nursing jobs
, while some from the most recent class to graduate from my school have landed jobs.
I was at an Open House when I started applying. Two of us sitting together had just graduated, and the hiring people at the Open House were interested in us. A third was in a prestigious direct-entry master's program that allows the student to sit for NCLEX after the first year, while continuing master's studies in the second year. She had been licensed for for a year, but had not yet found a job because she was working on her master's. The hiring people didn't even take her resume that was sitting next to ours on the table.
This is just an anecdote, but I don't think it's too far off of the general attitude toward long-licensed RNs that have never been employed as an RN, regardless of the reason.
