A client who is one day postpartum tells the nurse that her baby cannot latch onto the breast. The nurse determines that the client's nipples are inverted. Which action should the nurse implement?

Choice A rationale: Applying ice can cause vasoconstriction and potentially inhibit the let-down reflex. While it might temporarily firm the tissue, it does not effectively address the anatomical challenge of inverted nipples. Choice B rationale: While a pump can help draw out a nipple or maintain supply, the immediate concern is the baby's inability to latch at the breast for a successful feeding session. Choice C rationale: Offering formula as a first-line intervention can undermine the mother's breastfeeding goals and interfere with the establishment of her milk supply and the infant's natural sucking reflex. Choice D rationale: A breast shield is a silicone device that fits over the nipple and areola, providing a firm, protruded surface for the infant to latch onto when nipples are flat.
