A pregnant client diagnosed with depression expresses concern about pharmacological treatments due to the potential risks. What is the nurse's priority action when addressing her concerns?

A. Encouraging the client to decide independently without providing information is unsafe and does not support informed decision-making. Clients need evidence-based guidance to weigh risks and benefits. B. Consulting the healthcare provider about alternatives is appropriate, but the priority is first to educate the client about risks of untreated depression, as this information frames any subsequent discussion about therapy options. C. Advising against all medications during pregnancy is overly restrictive and may put both the mother and fetus at risk if depression remains untreated. Some antidepressants can be used safely under medical supervision. D. Educating the client about the potential adverse effects of untreated depression during pregnancy is the priority action. Untreated maternal depression can lead to poor prenatal care, preterm birth, low birth weight, impaired maternal-infant bonding, and worsening maternal mental health. By providing this information, the nurse helps the client engage in informed decision-making, weighing the risks of both treatment and non-treatment.
