Final answer:
The nurse should choose option C: 'Neither my hair nor my perfume is the focus of today's session.'
Step-by-step explanation:
The best response by the nurse to address the breach of boundaries would be option C: Neither my hair nor my perfume is the focus of today's session.
This response allows the nurse to acknowledge the client's comment while redirecting the focus of the session back to the client's issues. By avoiding confrontation or personalizing the comment, the nurse maintains professionalism and ensures that the therapeutic relationship remains intact. It is important for healthcare professionals to establish clear boundaries to maintain the integrity of the therapeutic environment.
