Final answer:
The social worker should facilitate a conversation about service termination and referrals, preparing and supporting the client for the transition to other resources. Professional boundaries and the agency's policy limitations make other options less suitable.
Step-by-step explanation:
The social worker's next step should be to facilitate a conversation regarding termination and potential referrals.
This conversation would involve discussing the client's progress, acknowledging the nearing end of eligibility for the agency's services, and introducing the referrals to other resources that have been located for the client's ongoing needs.
It is essential that the social worker prepares the client for the transition and ensures that the client understands how to engage with the new resources.
Moreover, empowering the client to advocate for themselves in the future is also a key element of the social worker's role.
