How might the nursing home's social worker help Ms. O's friends in visiting her?

The correct answer is B. Ms. O's friends, who are elderly and cannot drive, ride buses to visit her. The social worker can help by finding easier transportation options for them. Not having family around, friends' visits can significantly impact Ms. O's well-being. It may be challenging for the friends to ask for help themselves, so the social worker can reach out to volunteer groups for assistance. Making friends at the dialysis center might not be feasible due to the nature of treatments. Asking other residents' families to bring her friends could burden them further and might deter them from helping. It's important to consider the friends' convenience and emotional support for Ms. O.
