How does a nurse confirm successful lactogenesis after childbirth?

Recognizing the presence of colostrum is a key indicator of successful lactogenesis, which refers to the production of milk following childbirth. Colostrum is the first milk produced by the breasts, rich in antibodies and nutrients, and is typically apparent within the first few days postpartum. The presence of colostrum demonstrates that the body has begun the lactation process and is transitioning from pregnancy to breastfeeding.

The other options do not directly confirm lactogenesis. Observing the newborn's weight gain is more indicative of adequate feeding rather than the initiation of milk production. Monitoring maternal diet can be important for overall health but does not specifically indicate whether the lactation process has begun. Checking maternal anxiety levels may provide insight into her emotional state but does not reflect the physiological process of milk production. Thus, the recognition of colostrum is the most direct evidence of successful lactogenesis after childbirth.
