Final answer:
The next step for the OT would be to redirect the elderly woman to a different task.
Step-by-step explanation:
In this situation, the next step for the occupational therapist (OT) would be to redirect her to a different task. This is because the elderly woman with a diagnosis of depression and dementia is displaying a repetitive behavior, which could be a symptom of her condition. By redirecting her to a different task, the OT can help her engage in a more meaningful and purposeful activity, which may help alleviate her symptoms and provide her with a sense of accomplishment.
