Narrative:

We arrived at the cha airport at XA40L and proceeded to our aircraft. Given the early hour; the cha tower was still closed. The ASOS reported that the winds were 020 degrees at 9 KTS; visibility 10 miles; sky condition clear and that the approach was set up for runway 2. The first officer and I both had our taxi charts out and had briefed our departure for runway 2 and our taxi route as straight out of the ramp via taxiway east followed by a left turn on taxiway a. We executed a right-hand turnout of the gate with both engines running and headed westbound to join taxiway east. The first officer announced our intentions over the CTAF. Given the dark conditions at the time; the fact that there were numerous taxiway/runway intersections; there was confusion as to which taxiway was which. I taxied slow until we were sure that we knew where we were. We were both heads out and established the correct taxiway (taxiway east) and proceeded to cross runway 15/33. I expected and briefed an immediate left-hand turn onto taxiway a; and upon entering the runway environment; I turned on the left; right; and center landing lights and the wing inspection lights in addition to the taxi lights that were already on. As we came close to the far side of runway 15/33; I looked for the left turn and was surprised that we had not crossed a hold short line for runway 15/33; but were in very close proximity to the hold short line of runway 2/20. I applied the brakes as to not cross onto runway 2/20. At that point; the first officer and I heard a loud crash/bang and heard our flight attendant X scream. I brought the aircraft to a stop; set the parking brake and by that point the flight attendant called forward and informed us that she was hurt. We informed operations that we were returning to the gate and to have paramedics standing by. We taxied back to the gate and secured the engines. I went to the cabin to help the flight attendant. She told me that she had been standing near the galley; had fallen forward and struck her face and arm on the galley partition. I then opened the main cabin door to allow the paramedics on the aircraft. The paramedics evaluated her and informed me that they would need to transport her to the local hospital. After she had deplaned; the passengers were taken inside and the aircraft was repositioned to ZZZ.

Title: A Cabin Attendant fell and was hurt when the Captain of a CRJ-200 braked sharply to avoid a runway incursion in the dark at CHA. Confusing taxiway and runway intersections contributed.
