Which of the following best describes the risk associated with prolonged second stage of labor?

The option that best describes the risk associated with a prolonged second stage of labor is maternal fatigue leading to intervention. During the second stage, when the baby descends through the birth canal, the mother exerts significant physical effort, which can lead to exhaustion. Prolonged labor can increase the likelihood of fatigue, which may compromise the mother's ability to continue pushing effectively. As a result, this fatigue might necessitate medical interventions, such as the use of forceps, vacuum delivery, or even an emergency cesarean section if there are concerns for the well-being of the mother or fetus.

Other options do not accurately reflect the risks associated with a prolonged second stage. Increased satisfaction of birth experience is generally attributed to successful outcomes and support during labor rather than prolonged efforts leading to fatigue. Improved fetal positioning does not inherently correspond with prolonged labor; while positioning can be critical for delivery, prolonged labor may actually hinder optimal fetal positioning. Lastly, a prolonged second stage is more likely to increase the risk of cesarean delivery rather than reduce it, as challenges may arise that necessitate surgical intervention. Thus, maternal fatigue leading to intervention stands out as the primary risk in the context of prolonged labor.
