Final answer:
The nurse should provide breast shells and assist with a breast pump before feeding to aid a mother with inverted nipples in breastfeeding.
Step-by-step explanation:
In assisting a postpartum client with inverted nipples attempting to breast-feed, the nurse should provide breast shells and assist the mother with using a breast pump before each feeding. This procedure helps to draw out the nipples, making it easier for the newborn infant to latch on properly. Since proper latch-on is essential for successful breastfeeding, aiding the mother in this way can facilitate an effective feeding process and ensure that the infant receives the necessary nutrients and hydration contained in the mother's breast milk.
