Final answer:
The best response from the nurse to a child feeling bullied is to ask the child to elaborate on their feelings, validating their experience and potentially leading to more detailed discussions on how to address the issue.
Step-by-step explanation:
The most therapeutic response a school nurse could provide to a child expressing feelings of being bullied and isolated is option D: "Tell me more about how you feel." This response is empathetic and inviting, encouraging the child to express their emotions and experiences, which is a crucial first step in addressing bullying. It opens the door for developing a trusting relationship where the child feels heard and supported. Unlike the other options, this approach validates the child's feelings rather than offering solutions that might not be helpful or might inadvertently minimize the child's concerns.
