Final answer:
The most therapeutic response is to validate the woman's feelings of grief and anger, allowing her space to experience these emotions without judgment or pressure to move on prematurely.
Step-by-step explanation:
The most therapeutic statement the nurse could provide to the 63-year-old woman is option (b): "It's OK to grieve and be angry with your daughter and anyone else for a time." This acknowledges the woman's feelings without imposing the nurse's experiences or suggesting that the woman should be feeling differently. It validates her emotions and gives her permission to feel them, which is an important aspect of the grieving process. A therapeutic response should meet the patient where she is in her grief, honoring and validating her experience without comparing it to others or rushing her through her feelings.
