How long have you been at the job? If it's been less than a month or two, as a future employer I'd certainly question your not sticking it out longer. Absent some sort of fraudulent/illegal practice or "bait-and-switch" (e.g., hired to work with/in a specific population/location/format/etc.) where you show up on first day the job is DRASTICALLY different than what you were contracted to do, I'd be a bit wary. If the issue is something like different supervisor, small change in billable requirements, not the same office you expected I'd be very concerned about hiring you. In either case, have you built up some "capital" along the lines of a history of extended employment elsewhere? If you are early career, without a good work history, and it's only been a few weeks at this position (and no clear "bait and switch situation), I'm thinking along the lines of you being a bit impulsive or someone who didn't do their due diligence before accepting the offer. That may be TOTALLY off base, but a lot of time, energy, and money goes into onboarding clinical staff at a large operation such as an AMC, with multiple departments (HR, Clinical, Medical, Credentialing) involved. I'd be wary of taking that risk with you without a very compelling reason.
On the other hand, if you stick it out six-months to year and tell me in your interview that you knew clearly on day one that the position was not a good match but you hung around out of courtesy for the employer/clients/etc., then I'm more likely to be impressed with professionalism.
