The most appropriate time for the nurse to encourage a laboring woman to push is during

A. Right occiput posterior position: This position refers to the baby's head being down but facing the mother's back, which can make labor more challenging but is not a contraindication for amniotomy.

B. -2 station: This indicates that the baby's head is not yet engaged in the pelvis. While it can complicate labor, it is not an absolute contraindication for amniotomy, though caution is advised.

C. Cephalic presentation: This is the most common and favorable position for delivery, where the baby's head is down and ready for birth. It is not a contraindication for amniotomy.

D. Dilation less than 3 cm: This is a contraindication for amniotomy because the cervix is not sufficiently dilated, which can increase the risk of complications such as infection or prolonged labor.

Choice A reason:

Measuring urinary output. This is not the priority nursing care associated with an oxytocin infusion, because urinary output is not directly affected by oxytocin. Urinary output may be affected by other factors, such as fluid intake, dehydration, or kidney function, but these are not related to oxytocin administration. • Choice B reason:

Evaluating cervical dilation. This is also not the priority nursing care associated with an oxytocin infusion, because cervical dilation is a result of uterine contractions, not oxytocin itself. Oxytocin is used to stimulate or augment uterine contractions, but it does not cause cervical dilation directly. Cervical dilation is important to monitor during labor, but it is not the main focus of oxytocin infusion. • Choice C reason:

Increasing infusion rate every 30 minutes. This is not the priority nursing care associated with an oxytocin infusion, because increasing the infusion rate every 30 minutes is not a standard protocol for oxytocin administration. The infusion rate should be adjusted according to the patient's response and the provider's orders, but not arbitrarily or routinely. Increasing the infusion rate too quickly or too often can cause hyperstimulation of the uterus, which can be dangerous for both the mother and the fetus.

• Choice D reason:

Monitoring uterine response. This is the correct answer and the priority nursing care associated with an oxytocin infusion, because oxytocin can cause excessive or prolonged uterine contractions, which can lead to fetal distress, uterine rupture, or placental abruption. Therefore, the nurse must monitor the frequency, duration, and intensity of uterine contractions, as well as the fetal heart rate and blood pressure, to ensure that oxytocin is having the desired effect and not causing any adverse outcomes.
