How Soon is to Soon?

I have worked for the same health care facility for over 3 years now. x something months as a patient sitter, 2 years as a nursing aide on an oncology unit and an ICU, and currently I've worked 7months as an RN floating between a medical and surgical ICU. Recently my feelings about working for the facility have changed. With a mass quitting of nurses on our unit,we are dangerously understaffed (though I believe we have hired 8 more nurses). Also with the hospital's inability to flow patients through the ED, the ICU has become a holding ground of tele overflows. Currently I am dissatisfied with my work situation. I want to take care of true ICU patients, not overflows all the time.

I have only been a nurse for 7 months now, so I've been hesitant to attempt to quit. However, this all changed. I recently received a text from a friend who's manager wants my resume ASAP. It would be on a Nero ICU in a downtown hospital. Even though I am not a fan of Nero, the opportunity would be a foot in the door to a wonderful working environment and an amazing opportunity. My question is, would it be too soon to leave my current job with only 7months as an RN? The new hospital knows my current experience.

p.s. I apologize if my grammar is sub-par
