A client has been in labor for 10 hours.

(A) It is very important that there is a resting phase or relaxation period between the contractions. During this period, the uterus, placenta, and umbilical vessels re-establish blood flow. No resting phase between contractions can lead to fetal bradycardia, fetal hypoxia, and acidosis. It can also result in a tetanic contraction, which can cause uterine rupture. (B) The goal of the oxytocin infusion is to help establish a contraction pattern lasting 45–60 seconds occurring every 2 minutes and a uterine tonus of 60–70 mm Hg. (C) This choice is correct. The uterus has time to recover from the contraction. (D) The client’s tiring is no indication to stop the infusion. She will be tired even without the infusion.
