I don't think you'd be at a disadvantage. My ANP program's focus was on cardiovascular, consisting of blood pressure control, diabetes, cardiac, endo and was loaded with primary care, pain, derm, male/female issues. We even had 1/2 semester classes devoted to Gero and adolescent issues, focusing on dementia, acne, common sexual, psychological teen related discusssions, etc.
I think it's good to have options. I've thought about going back slowly to get a few counseling classes myself. I've always wanted to be able to offer some counseling to patients or volunteer my time during evenings/weekends for those who just need someone to talk to (or even a suicide hot-line, etc). Working in an ER, I really look up to the Psych folks...don't know how you do it.
To me, ANP and med/surg are two different animals. There is no time in the ANP program devoted to surgical issues. I'm sure there are programs which can be modified or customized for this, but I'd guess the ACNP folks are the ones who study this area. I know at my school, the ACNPs could choose to specialize, but not the ANPs. Now, if I'd wanted to chose a surgical preceptor, that might have been an option, but the ANP exam had nothing about surgical issues on it, so my director might have had issues w/this.
I think you're headed in the right track if you wish to work in a community health clinic. ANPs deal w/this type of work everyday. Health maintenance, primary care, etc. Good luck!
