Which of the following is an indication for administering an epidural?

Administering an epidural is indicated primarily for pain management during labor. When maternal request occurs during active first-stage labor, it typically signifies that the mother is experiencing significant pain and is seeking relief to facilitate a more positive labor experience. The decision to provide an epidural in this context aligns with the principles of shared decision-making in maternal care.

While other options may involve considerations relevant to labor management, they do not specifically justify the routine use of an epidural in the same direct manner. Maternal anxiety can be addressed through other supportive measures, and a history of prolonged labor does not inherently call for an epidural unless there's also an indication of pain management needs. Lastly, epidurals are not indicated solely due to fetal distress; in situations of fetal distress, other interventions are prioritized to ensure fetal safety, and the timing of an epidural may not be appropriate.
