A woman who gave birth 48 hours ago is experiencing swollen, warm, and tender breasts. What should the nurse do first?

In the context of a woman who has recently given birth and is experiencing swollen, warm, and tender breasts, the correct action to take first is to apply cold compresses to both breasts for comfort. Cold compresses can effectively reduce swelling and provide relief from discomfort associated with engorgement or conditions like mastitis, which can manifest in the first few days postpartum.

The application of cold compresses helps to constrict the blood vessels, decreasing inflammation and numbing the area, thereby alleviating pain. This immediate comfort measure supports the mother's well-being during a time when she can experience significant physical changes and discomfort as her body begins to respond to breastfeeding or weaning.

While other options may provide relief, such as expressing milk to alleviate pressure or using warm water to promote let-down, they might not address the initial discomfort caused by swelling and tenderness as effectively as cold compresses. A loose-fitting bra can help with comfort as well, but it does not directly address the acute issue of swelling and tenderness. Hence, the application of cold compresses serves as an appropriate first step in managing the situation.
