This may not be so harmful if it was only a gulp. The two oils will mix okay and may not do any damage.
The chances for damage are high if you drive the vehicle that way, so change it immediately, for the safety of your seals and pump. Draw out as much fluid out with a turkey baster or syringe as absolutely possible. Then refill it with power steering fluid and repeat and few times. Depending on the vehicle, that will probably be fine, however, some vehicles are more picky than others (Hondas, for example, tend to be very particular about their power steering fluid) and if your vehicle isn't running right, then a full flush will be necessary. If all else fails, visit your local mechanic.
