The best way to break a broody is to keep her in a small cage off the ground with a wire bottom for three or four days. The wire bottom keeps her undersides cool, which seems to help. Give her food and water and she should be fine. Do not give her anything that looks like a nest or nesting materials.
If you don't have the wire cage, any small cage will do, but it might take a little longer. Just find a way to keep her from going back to her nest.
Being broody is hard on a hen. Most can handle it but it is a stressful time. Why put your hen through that?
Laffindog, check your chickens for mites, especially red mites. I'll include a link. One of the biggest killers of broody hens is red mites. One week of being broody should not have killed her.
