A nurse is preparing to administer dinoprostone gel to a client who is pregnant. The client asks the nurse about the purpose of the medication. Which of the following responses should the nurse make?

Choice A reason: Position the client on her side is correct, as this is the first action the nurse should take according to the ABCDE priority framework. Late decelerations are symmetrical decreases in the fetal heart rate that begin after the peak of the contraction and return to baseline after the contraction ends, which indicate uteroplacental insufficiency and fetal hypoxia. Positioning the client on her side can improve blood flow and oxygen delivery to the placenta and fetus by relieving pressure on the vena cava and aorta.

Choice B reason: Elevate the client's legs is incorrect, as this is not a priority action for a client who has late decelerations. Elevating the legs can increase venous return and cardiac output, but it can also reduce blood flow and oxygen delivery to the placenta and fetus by compressing the vena cava and aorta.

Choice C reason: Administer oxygen via face mask is incorrect, as this is not the first action the nurse should take, although it is important to do later. Administering oxygen can increase oxygen saturation and delivery to the placenta and fetus, but it does not address the cause of uteroplacental insufficiency or improve blood flow.

Choice D reason: Increase the infusion rate of the IV fluid is incorrect, as this is not the first action the nurse should take, although it may be indicated later. Increasing the infusion rate of IV fluid can expand blood volume and improve placental perfusion, but it does not address the cause of uteroplacental insufficiency or improve blood flow. The nurse should obtain a provider's order before increasing the IV fluid rate.

Choice A reason: Amniotic fluid in the vaginal vault indicates that the membranes have ruptured, but this does not necessarily mean that the client is in labor. Some women may have a slow leak of amniotic fluid for hours or days before labor begins. Rupture of membranes also increases the risk of infection, so the nurse should monitor the client's temperature and fetal heart rate.

Choice B reason: Contractions every 3 to 4 minutes are a sign of labor, but they are not enough to confirm it. The nurse should also assess the duration and intensity of the contractions, as well as the client's response to them. Some women may have false labor contractions, also known as Braxton Hicks contractions, which are irregular, mild, and do not cause cervical changes.

Choice C reason: Pain just above the navel is not a typical sign of labor. It may indicate other problems, such as placental abruption, uterine rupture, or fetal distress. The nurse should report this finding to the nurse midwife and check for other signs of bleeding, shock, or fetal compromise.

Choice D reason: Cervical dilation is the most reliable indicator of labor. It means that the cervix is opening and thinning out to allow the passage of the fetus. The nurse should measure the cervical dilation in centimeters and document it along with the station and effacement of the cervix.
