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: The cervix is effaced 3 cm, it is dilated 30%, and the presenting part is 1 cm above the ischial spines is incorrect, as this does not follow the correct order and measurement of cervical assessment. Cervical effacement is measured in percentage, not in centimeters, and it indicates the thinning or shortening of the cervix. Cervical dilation is measured in centimeters, not in percentage, and it indicates the opening or widening of the cervix.

Choice B reason: The cervix is dilated 3 cm, it is effaced 30%, and the presenting part is 1 cm above the ischial spines is correct, as this follows the correct order and measurement of cervical assessment. Cervical dilation, effacement, and station are recorded in that order to describe the progress of labor. Station refers to the relationship between the presenting part of the fetus and the maternal pelvis, measured by the level of the ischial spines. A negative station means that the presenting part is above the spines, while a positive station means that it is below.

Choice C reason: The cervix is effaced 3 cm, it is dilated 30%, and the presenting part is 1 cm below the ischial spines is incorrect, as this does not follow the correct order and measurement of cervical assessment. Cervical effacement is measured in percentage, not in centimeters, and it indicates the thinning or shortening of the cervix. Cervical dilation is measured in centimeters, not in percentage, and it indicates the opening or widening of the cervix.

Choice D reason: The cervix is dilated 3 cm, it is effaced 30%, and the presenting part is 1 cm below the ischial spines is incorrect, as this does not match the documentation of station. A negative station means that the presenting part is above the spines, while a positive station means that it is below.
