Narrative:

During cruise flight at FL290 we received a frequency change to ZDC. I was the PNF and first officer was the PF. I checked on with center and shortly thereafter we received a TA 'traffic, traffic' aural alert. We saw the traffic on the TCASII system. It was at our 1 O'clock position and 1500 ft below us. He was climbing but I do not know at what rate. We began to look for traffic visually. As we were looking, we received an RA, 'climb, climb' aural warning. First officer disconnected the autoplt and began a climb as instructed by the TCASII system. As the airplane began the climb, I called for the controls and continued the climb at a greater rate. We received the 'clear of conflict' aural at FL300. I xferred the controls back to the first officer. I then called ATC to notify them of the RA. They reclred us back to FL290. I then called the flight attendant to let her know about the RA and to check that everyone was ok. One of the non-revenue pilots answered the interphone and notified me that the flight attendant had injured her ankle. They helped her to a seat and placed ice on her ankle. I called dispatch on comrdo and informed them of the situation and that there may be a potential delay with our flight to rdu. I told the dispatcher that we would need a paramedic to meet us at the airplane in jfk to assess flight attendant's injury. He offered to make those arrangements. After we landed in jfk the paramedics took flight attendants to the medical facility. I then called scheduling to inform them of the situation. I called the chief pilot's office to inform them of the situation as well. Supplemental information from acn 627121: MD83 was climbing to FL280. There was level traffic at FL290. The crj at FL290 received a TCASII alert and responded. I was informed that the flight attendant was injured during the TCASII alert. Supplemental information from acn 625699: we received an audible TA alert from the TCASII. I looked at the mfd and noticed that there was an aircraft at our 12-1 O'clock position. It was about 2000 ft below us and climbing at a rate of approximately 500 FPM. At about 1400 ft below us, I spotted the other aircraft, an MD83. At that time, I announced 'traffic in sight' and pointed in the direction of the MD83 to aid the captain.
