Primary vs Acute Care NP to Work in an Outpatient Specialty Area?

[Spine_CRNA, BSN, RN]

Hello,

I'm very new to NP talk as I decide my next move past M/S nursing so I apologize if my question is dumb. However, searching the internet provides little more than a firehose of information that's hard to sift through.

1.) If I want to work in an outpatient setting within a specialty like cardiology, nephrology, etc. should I go with a Primary Care NP degree (FNP) or an Acute Care one (Adult-Gerontology Acute Care NP) in order to be well trained and marketable post graduation?

2.) Also, how do I go about specializing as an NP? A school like UPENN has it built into the curriculum. However, that seems to be the minority. I'm thinking one either chooses specific courses/clinicals during the coursework or one gets a general adult NP degree and applies for a specialty clinic to work in after graduation.

I've little to no interest in working with kids as my career has been in Adult Liver patients.

Your time and effort in responding to my thread are GREATLY appreciated.

John
