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 B
Explanation
Choice A reason: Wear a nipple shield is incorrect, as this recommendation is not indicated for a client who has engorged breasts. A nipple shield is a thin, flexible device that covers the nipple and areola and can help with latch problems, flat or inverted nipples, or sore nipples. However, a nipple shield can also reduce milk transfer, stimulate less milk production, and cause nipple confusion or preference.
Choice B reason: Express milk from both breasts is correct, as this recommendation can help relieve engorgement and maintain milk production. Engorgement is a normal and expected phenomenon that occurs when the milk comes in, usually around 72 to 96 hr after birth. Engorgement can cause breast fullness, tenderness, warmth, and hardness. The nurse should advise the client to express milk from both breasts by breastfeeding frequently and effectively or by using a breast pump or hand expression.
Choice C reason: Obtain a prescription for an antibiotic is incorrect, as this recommendation is not indicated for a client who has engorged breasts. An antibiotic is used to treat mastitis, which is an infection and inflammation of the breast tissue that can cause redness, pain, swelling, warmth, and fever in the affected breast. The nurse should assess the client for signs of mastitis and report any abnormal findings to the provider.
Choice D reason: Apply a heating pad to her breasts is incorrect, as this recommendation can worsen engorgement and cause discomfort. A heating pad can increase blood flow and swelling in the breasts, which can impair milk flow and increase pain. The nurse should advise the client to apply cold compresses or cabbage leaves to her breasts to reduce inflammation and discomfort.
Correct Answer is B
Explanation
Choice A reason:
A warm sitz bath can promote healing and comfort, but it is not recommended until 24 hr after delivery, as it can increase swelling and bleeding.
Choice B reason:
An ice pack can reduce inflammation and pain by causing vasoconstriction and numbing the area. It should be applied for 20 minutes at a time, with a cloth barrier between the skin and the ice.
Choice C reason:
A soft pillow under the client's butocks can increase pressure on the perineum and worsen the pain. The client should be encouraged to lie on her side or sit in a semi-Fowler's position.
Choice D reason:
A heating lamp can dry out the wound and delay healing. It can also cause burns and discomfort. It should be avoided for episiotomy care.
