Which of the following is an appropriate intervention for a patient in labor experiencing back pain?

Providing a hot or cold pack to the lower back is an appropriate intervention for a patient in labor experiencing back pain. Heat can increase blood flow, relax muscles, and reduce pain perception, which can be especially beneficial during labor when a woman might experience discomfort or tension in her back. Cold therapy can also help reduce inflammation and numb sharp pain. The choice between heat or cold can depend on the specific situation and personal preference, but both methods are commonly used to alleviate back pain.

In contrast, encouraging the mother to lie on her back may actually exacerbate back pain, as this position can place additional pressure on the spine and decrease overall comfort. Suggesting she remain inactive is not ideal either; movement and changing positions can often relieve pain during labor. Performing a gentle abdominal massage may not address the specific discomfort in the lower back effectively, and massages in that area might not provide the relief needed. Therefore, using a hot or cold pack remains a well-supported intervention for managing back pain in labor.
