答案
参考答案：C
解析：A drop in fetal heart rate signals fetal distress and may indicate the need for a cesarean delivery to prevent neonatal death. Maternal blood pressure, pulse rate, respiratory rate, intake and output, and description of vaginal bleeding are all important assessment factors; however, changes in these factors don’t always necessitate the delivery of the neonate.
