An elderly woman experiences short-term memory problems and occasional disorientation a few weeks after her husband's death. She also is not sleeping, has urinary frequency and burning, and sees rats in the kitchen. The home care nurse calls the woman's primary health care provider to discuss the client's situation and background, assess, and give recommendations. The nurse concludes that the woman:

1. Is experiencing the onset of Alzheimer's disease.

2. Is having trouble adjusting to living alone without her husband.

3. Is having delayed grieving related to her Alzheimer's disease.

4. Is experiencing delirium and a urinary tract infection (UTI).
