Wound care encompasses pressure ulcers, peripheral vascular ulcers, diabetic foot ulcers, chemical burns and regular burns, lacerations, surgical sites, wound vacs, etc. My experience is strictly as a wound care nurse for a SNF - however, I imagine it is similar to hospital work.
Generally, you are responsible for wound care for all wounds, documentation, implementing interventions, care plans
, MD and family notification. Also you are responsible for weekly measurements with appropriate documentation. In some facilities you may have secondary functions such as weights variance or IDT along with the RD.
I was relatively inexperienced when I accepted a wound care position at the SNF where I work. However it has changed my desired path and I truly enjoy doing it. You have to have a strong stomache at times, and you have to not mind poking around in someone's gaping wound with a cotton swab as well.
Hope this helps fill in the basics. I can reccomend looking in the wound care forum here at All Nurses, there are links to good sites for learning more. Also you did not mention if your LVN or RN - but there are two different certs for wound care nurses depending.
I think important skills for wound care are attention to detail, a sense of humor, excellent documentation skills, and the desire to continue learning everyday.
