Final answer:
The nurse would intervene if an expectant parent claimed that formula feeding is more convenient, as this contradicts the promotion of breastfeeding and its benefits such as nutrition, passive immunity, and bonding. The correct option is c.
Step-by-step explanation:
The nurse would intervene if an expectant parent makes the statement c) Formula feeding is more convenient and time-saving. This statement suggests a preference for formula feeding over the many benefits of breast milk, which the nurse is promoting in the discussion. Breast milk provides the ideal nutrition and passive immunity to the baby, which are significant advantages over formula feeding. Colostrum, the first milk produced, is particularly important as it is rich in immunoglobulins, helping to boost the newborn's immune system. Additionally, the process of breastfeeding also encourages bonding between mother and baby, stimulates milk production through positive feedback, and can help the mother return to her pre-pregnancy weight.
