What statement indicates that a parent understands teaching about caring for a newborn post-circumcision?

Applying petroleum jelly to the penis with each diaper change is a correct approach for caring for a newborn following a circumcision. This practice helps to prevent the diaper from sticking to the surgical site and reduces irritation during the healing process. It promotes a moist environment, which is beneficial for healing and can reduce discomfort for the baby.

In contrast, cleaning the area with alcohol is not recommended, as alcohol can irritate the sensitive skin of the newborn and may disrupt healing. Avoiding diaper changes altogether for the first week is not practical and can lead to other issues, such as infection or further irritation. Similarly, using a bandage to cover the area is generally unnecessary and could cause more harm than good, as proper exposure to air can facilitate healing and prevent moisture buildup that may lead to complications.
