Certification advice

Hi, I am a new grad and currently work on an inpatient post-op floor in a trauma 1 hospital. They require that RNs receive some sort of certification after the first year. Most do the med-surg track, but I'm not planning on staying in the hospital setting more than 2 years so I can go into home health, probably with a local VNA. So I'm wondering if something like a wound care cert might be better for HH and make me more marketable for my first HH job, come that time. Any thoughts?
