A nurse is speaking with a client who is addicted to heroin and who just learned that she is pregnant. The client states, "I just started taking methadone. Is there anything else I can do to make sure my baby is healthy?" Which information should the nurse provide?

A. Describe genetic testing protocols: Genetic testing is not specifically indicated due to heroin addiction or methadone use. While it may be part of routine prenatal care, it does not address the immediate steps for optimizing pregnancy outcomes in this context. B. Start a prenatal care plan as soon as possible: Early and consistent prenatal care is essential for monitoring maternal and fetal health, managing methadone therapy safely, and reducing complications associated with substance use during pregnancy. This intervention directly supports a healthy pregnancy outcome. C. Sign up for group therapy sessions: Counseling and support groups are beneficial for addiction management, but they complement rather than replace essential prenatal care. Immediate medical oversight is the priority. D. Discontinue the methadone right away: Abruptly stopping methadone can precipitate withdrawal in the mother and fetus, increasing the risk of complications. Continuation under medical supervision is critical for maternal and fetal safety.
