The nurse knows that which of the following is not a cause of mastitis?

Choice A rationaleInfrequent or inconsistent feedings lead to milk stasis, providing an environment conducive to bacterial growth, which can result in mastitis. Proper breastfeeding frequency ensures milk drainage, reducing stasis and infection risk. Milk stasis is a primary contributor to the development of mastitis, emphasizing the importance of regular feeding practices.Choice B rationaleNipple cracks and fissures are a direct portal for bacterial entry, increasing the likelihood of infection in the lactiferous ducts. Staphylococcus aureus, commonly present on the skin, can invade through damaged tissue, resulting in mastitis. Proper nipple care and hygiene are essential in prevention.Choice C rationaleGradual weaning allows for a decrease in milk production, preventing engorgement and stasis, which reduces the risk of mastitis. Gradual weaning gives the mammary glands time to adapt. Mastitis is more commonly associated with abrupt changes in feeding patterns or milk stasis rather than controlled weaning processes.Choice D rationaleEngorgement from oversupply creates increased intraductal pressure, which can lead to blocked ducts and milk stasis, creating conditions favorable for bacterial growth. Engorgement needs prompt management to prevent secondary infections such as mastitis, particularly in lactating individuals.
