An unimmunized school-age child whose mother is in her first trimester of pregnancy is diagnosed with rubella after a local outbreak. What should the primary care pediatric nurse practitioner recommend?

• A. MMR vaccine for the mother and child
• B. Assessment of maternal rubella titers
• C. Intravenous immunoglobulin for the child
• D. Possible termination of the pregnancy

Answer: (B)

When rubella exposure occurs in a pregnant woman, the first step is to determine her immune and infection status through rubella serology. Checking maternal rubella IgG and IgM titers clarifies whether she is already immune, has a current acute infection, or is susceptible. This information guides what to do next and how to counsel the family. Vaccinating a pregnant woman with the MMR vaccine is not allowed because it is a live attenuated vaccine and could harm the fetus, so it will not be given during pregnancy. There is no specific antiviral therapy for rubella in pregnancy, so management centers on confirming infection status and continuing prenatal counseling, with postpartum vaccination for the mother to prevent future pregnancies from being affected.IVIG for the child with congenital rubella is not routinely beneficial, and decisions about termination, if fetal infection is confirmed, involve careful discussion with obstetrics and depend on gestational age and local guidelines. The immediate, best next step is to assess maternal rubella titers to determine infection status and fetal risk.
