Narrative:

During approach to runway 22 at rdm at approximately 7 miles from the airport on a right base; setting up for a 2 mile final we got a 'terrain; pull up' ground proximity warning. It only sounded once and was gone. The altitude at the time was 5;000 ft MSL. I immediately responded with the GPWS recovery procedure and climbed to approximately 5;500 ft. The display on the mfd was set to 10 mile scale. At no time did I see any terrain on our flight path that was at an altitude above us. The rest of the flight (5 minutes) was uneventful. Looking back at the flight perhaps our descent was closer to the higher terrain northwest of the airport. The smith rock area. Neither the first officer nor myself felt that we were close enough to the higher terrain. We both had the airport in sight from beyond 50 miles. At 30 miles from the airport; we were cleared for the visual approach. I maintained a course direct to the airport until about 7-10 miles out when I maneuvered to the base leg. Looking back; I would have continued to the airport and entered on the downwind.
