A 25-year-old mother with opioid use disorder is in recovery with buprenorphine therapy. At her postpartum visit, she expresses fear of relapse due to social stressors and lack of support. Which nursing intervention best promotes long-term health?

Rationale: A. Recommending immediate discontinuation of buprenorphine is unsafe; abrupt cessation can trigger relapse and withdrawal symptoms. B. Encouraging her to rely solely on personal effort ignores the importance of social support and structured treatment in recovery. C. Focusing only on infant milestones neglects the mother’s health needs and risk of relapse, which are crucial for both her and the infant’s well-being. D. Referring her to a peer support group and coordinating follow-up with addiction services promotes long-term recovery by providing ongoing support, monitoring, and access to resources, which are evidence-based strategies for sustaining abstinence and improving maternal and infant outcomes.
