Final answer:
Neglecting her own needs to care for the client poses the highest risk to interfering with the client's recovery from substance use disorder, as it can lead to caregiver burnout and undermine the support they provide.
Step-by-step explanation:
The behavior that is recognized as having the highest potential to interfere with the client's recovery after discharge to home is neglecting her needs to care for the client. When a caregiver neglects their own needs, they can become overwhelmed, leading potentially to burnout and an inability to provide the necessary support for the client's recovery from substance use disorder (SUD).
Caregivers should maintain their own well-being to effectively support their loved ones, which might involve setting boundaries and enlisting external support systems. Advice and opinions can be helpful when asked for, setting limits can promote a structured environment conducive to recovery, and ignoring requests for money prevents enabling harmful behaviors. Therefore it is crucial for the mother to find a balance in caregiving that prioritizes her health as well as supports the client's journey to sobriety.
