Final answer:
A nurse should address the psychiatric-mental health client's concern with empathy and offer to discuss their feelings or communicate with the doctor to clarify the situation.
Step-by-step explanation:
When a psychiatric-mental health client tells the nurse about their perception that the doctor dislikes them, the most therapeutic response would be to address the concern empathetically while also clarifying the situation. A good response might be, 'I understand you're feeling upset because the doctor didn't come by after dinner as promised. Sometimes emergencies can change their schedules unexpectedly. Would you like to talk about how his absence made you feel, or can I help convey any concerns to him?'
