Final answer:
An appropriate initial nursing response would be to help the client explore personal attitudes.
Step-by-step explanation:
An appropriate initial nursing response to a client with Crohn's disease who believes that their partner's behavior has caused an increase in their symptoms would be to:
A. Help the client explore personal attitudes.
This response allows the nurse to understand the client's beliefs and attitudes towards their partner's behavior, and how it may be impacting their health. Exploring personal attitudes can help the nurse determine appropriate interventions and provide support to the client.
It is important for the nurse to approach the situation without judgement and provide a non-biased environment for the client to express their concerns.
