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?

Choice A reason: Administer terbutaline if the fundus is boggy is incorrect, as this action is contraindicated for a client who has a boggy fundus. Terbutaline is a tocolytic agent that can relax uterine contractions and worsen uterine atony and hemorrhage. The nurse should administer oxytocin or other uterotonic agents as prescribed to stimulate uterine contraction and prevent bleeding.

Choice B reason: Observe the lochia during palpation of fundus is correct, as this action can provide information about the amount, color, consistency, and odor of lochia. Lochia is the vaginal discharge that occurs after birth, which consists of blood, mucus, and tissue. The nurse should observe the lochia during fundal palpation and report any abnormal findings, such as excessive bleeding, large clots, foul smell, or infection.

Choice C reason: Document fundal height is correct, as this action can provide information about the progress of uterine involution. The fundus is the upper part of the uterus that can be palpated through the abdomen after birth. The nurse should document the fundal height in relation to the umbilicus and note any changes over time.

Choice D reason: Massage a firm fundus is incorrect, as this action is not necessary for a client who has a firm fundus. A firm fundus indicates adequate uterine contraction and involution and prevents excessive bleeding. The nurse should massage a boggy or soft fundus until it becomes firm and midline.

Choice E reason: Determine whether the fundus is midline is correct, as this action can provide information about the position of the uterus and bladder. The fundus should be midline and not displaced to either side. A deviated fundus can indicate bladder distension, which can interfere with uterine contraction and involution and increase the risk of hemorrhage and infection. The nurse should assist the client to empty their bladder and reassess the fundal position.

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.
