A nurse is assisting in the care of a client who is in active labor. The nurse notes variable decelerations of the FHR. The nurse should identify which of the following as a cause of variable decelerations?

Fetal head compression

Polyhydramnios

Maternal fever

Umbilical cord compression

Answer and Explanation

The Correct Answer is D

Choice A reason:
Fetal head compression is incorrect, as this factor can cause early decelerations in the fetal heart rate. Early decelerations are symmetrical decreases in the FHR that mirror the contractions, which indicate fetal head compression and vagal stimulation. Fetal head compression occurs as the fetus descends into the birth canal and does not pose a threat to the fetal well-being.

Choice B reason:
Polyhydramnios is incorrect, as this factor can cause variable or late decelerations in the fetal heart rate, depending on the underlying cause. Polyhydramnios refers to an excessive amount of amniotic ﬂuid, which can result from fetal anomalies, maternal diabetes, multiple gestation, or other conditions. Polyhydramnios can cause umbilical cord prolapse, uterine overdistension, or placental abruption, leading to reduced blood ﬂow and oxygen delivery to the fetus.

Choice C reason:
Maternal fever is incorrect, as this factor can cause late decelerations in the fetal heart rate. Late decelerations are symmetrical decreases in the FHR that begin after the peak of the contraction and return to baseline after the contraction ends, which indicate uteroplacental insufficiency. Maternal fever can increase maternal and fetal metabolism and oxygen demand, leading to fetal hypoxia and acidosis.

Choice D reason:
Umbilical cord compression is correct, as this factor can cause variable decelerations in the fetal heart rate. Variable decelerations are abrupt decreases in the FHR that vary in onset, duration, and depth, which indicate umbilical cord compression and reduced blood ﬂow to the fetus. Umbilical cord compression can occur due to cord prolapse, nuchal cord, short cord, or other causes. The nurse should reposition the client, administer oxygen, and prepare for delivery if indicated.

Correct Answer is B

Explanation

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.

A. Place the client in a lateral position. B. Notify the provider. C. Increase IV ﬂuid rate. D. Elevate the legs.

Correct Answer is A

Explanation

Choice A reason:
Placing the client in a lateral position is the first action the nurse should take, as it can improve maternal and fetal circulation by relieving pressure on the inferior vena cava. The client's blood pressure is low, which can indicate hypotension due to epidural anesthesia or supine hypotension syndrome.

Choice B reason:
Notifying the provider is an important action, as it can facilitate further interventions and monitoring for the client and the fetus. However, this is not the first action the nurse should take, as it does not address the immediate problem of hypotension.

Choice C reason:
Increasing IV ﬂuid rate is an important action, as it can expand blood volume and increase blood pressure. However, this is not the first action the nurse should take, as it may not be eﬀective if the client is in a supine position.

Choice D reason:
Elevating the legs is an important action, as it can enhance venous return and increase blood pressure. However, this is not the first action the nurse should take, as it may worsen supine hypotension syndrome by increasing pressure on the inferior vena cava.
