how long to wait to apply for another position

Hello

I am having a career crisis I believe. I have been a nurse for over 14yrs. I am so over bedside nursing and have been looking at other areas such as PACU, OR, Endoscopy. However, most of these positions require experience or critical experience. I tried to work on a critical care unit for a year and absolutely hated it. My co workers were supportive and so was my manager. I just hated the acuity of the pts and was stressed out everyday. I only lasted a year. I finally decided to go back to med/surg since that's what I am familiar with. I have been at my current position and hospital for 3 months.

So found a position in PACU at a hospital that I worked at previously. It says "new nurses welcome" which makes me think they will train you and no previous is needed. I of course want to apply. I figure, it can't hurt to apply. However, if I get the position, would it be wrong to quit my current job only after 3 months. I get so worried about moving around. Again I have been a nurse for over 14 yrs, and have worked at four different hospitals. I feel the only reason I lasted that long was because I moved around.

I am interested on how others feel about moving around, what's an appropriate length of time to stay at a place(if any) and trying different specialties in nurses.

Thanks to all who read and respond.
