BSN317 - Carswell is one of the five BOP Medical Referral Centers. It specializes in Mental Health for females, and Tertiary Medical Care for males and females. While most BOP facilities are Ambulatory Care, you could actually work inpatient Nursing at Carswell (which is actually Fort Worth, TX).
The other Medical Centers are at Rochester, MN (about a mile from the Mayo Clinic); Butner, NC; Springfield, MO, and Lexington, KY.
If you are interested in any of these places, I would suggest contacting the Director of Nursing at these places. For other BOP Facilities, the Health Services Administrator (HSA) is the best contact.
If they are interested in you, you need to be persistent. Once you have an offer of employment, they will invite in for an interview (or teleconference interview). An then and "quick" BOP Physical exam (vital signs, chest x-ray, etc) and a UA drug screen.
After that, you are in. Report to duty, work about a month, and then off to Glynco, Georgia for 3 week of training at the Federal Law Enforcement Training Center. Here, they will teach you the basics of working around Inmates.
Is it dangerous, not really. Correctional Officers are the main responders to fights. In Health Services, I have never had any problems. We do run to emergencies with the stretcher and medical bag.
If you are interested in Atlanta, then contact the Health Services Administrator there. They might have an RN opening.
My best advice with the BOP is persistance. Just getting through with a telephone call can sometimes take several tries, just because people are doing things in the prison and not sitting next to a telephone all day. (The solution, ask to have them Paged.)
