To reduce risk of mastitis during breastfeeding, which instruction should the nurse include?

• A. Block the milk duct with a bra
• B. Apply heat to breast
• C. Remove all clothing
• D. Use your finger to release suction after feeding.

Answer: (D)

The key idea is preventing milk stasis and nipple trauma to lower the risk of mastitis. After a feeding, gently slip a finger into the corner of the baby’s mouth to break suction before removing the baby. This helps the breast drain fully and reduces tugging on the nipple, protecting tissue and ducts from micro-tears and clogging. When drainage is complete and the nipple is preserved, the chance of blocked ducts and subsequent mastitis decreases.

Wearing a bra that blocks or compresses the ducts can trap milk and increase engorgement or blockage, making mastitis more likely. Heat is sometimes used for engorgement but isn’t the preventive measure here, and removing all clothing doesn’t affect breast drainage or nipple protection.
