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
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 C
Explanation
Choice A reason: "You will experience urinary retention." is incorrect, as this statement does not describe a sign preceding the onset of labor. Urinary retention can occur during labor due to pressure from the fetal head or epidural anesthesia, but it is not a sign that labor is imminent. The nurse should encourage the client to void frequently and monitor their bladder status.
Choice B reason: "You will have a decrease in vaginal discharge." is incorrect, as this statement does not describe a sign preceding the onset of labor. Vaginal discharge can increase before labor due to cervical ripening and dilation, which can cause bloody show or mucus plug loss. The nurse should educate the client about normal and abnormal vaginal discharge and when to report it.
Choice C reason: "You will experience a surge of energy." is correct, as this statement describes a sign preceding the onset of labor. A surge of energy, also known as nesting instinct, can occur before labor due to hormonal changes or psychological factors. The nurse should advise the client to conserve their energy and rest as much as possible before labor.
Choice D reason: "You will have a weight gain of 0.5 to 1.5 kilograms." is incorrect, as this statement does not describe a sign preceding the onset of labor. Weight gain can occur during pregnancy due to fetal growth, fluid retention, or increased caloric intake, but it is not a sign that labor is imminent. The nurse should monitor the client's weight and fluid balance and report any sudden or excessive weight gain that may indicate preeclampsia or other complications.
Correct Answer is A
Explanation
Choice A reason:
Checking the consistency of the client's uterine fundus is the first action the nurse should take, as it can indicate the cause of excessive bleeding. A boggy or soft fundus indicates uterine atony, which is the most common cause of postpartum hemorrhage. The nurse should massage the fundus until it becomes firm and contracted.
Choice B reason:
Having the client use the bedpan to urinate is an important action, as a full bladder can displace the uterus and prevent it from contracting properly. However, this is not the first action the nurse should take, as it does not address the immediate source of bleeding.
Choice C reason:
Increasing the client's fluid intake is an important action, as it can help replace fluid loss and prevent hypovolemia and shock. However, this is not the first action the nurse should take, as it does not stop the bleeding.
Choice D reason:
Preparing to administer oxytocic medication is an important action, as it can stimulate uterine contractions and reduce bleeding. However, this is not the first action the nurse should take, as it requires a provider's prescription and may not be necessary if fundal massage is effective.
