Step-by-step explanation:
The nurse should include the statement: 'Rubella vaccine is crucial to prevent birth defects in future pregnancies.' Rubella, also known as German measles, is a teratogenic virus that can cause developmental defects in the fetus if the mother is infected during pregnancy. Vaccinating postpartum patients against rubella is important to prevent congenital rubella syndrome and its associated birth defects. It is not necessary to wait for complications or future pregnancies to consider the rubella vaccine, as the vaccine provides protection against the disease for the individual as well as the community.
