A nurse is teaching a group of pregnant clients about the risk factors for umbilical cord prolapse.
Which of the following factors should the nurse include? (Select all that apply.)
Polyhydramnios
Breech presentation
Premature rupture of membranes
Post-term pregnancy
Multiple gestation
Correct Answer : A,B,C,E
The correct answer is choices A, B, C and E. These are all risk factors for umbilical cord prolapse, which is a complication that occurs when the umbilical cord drops through the cervix and into the vagina ahead of the baby during delivery. This can cause fetal hypoxia and distress by compressing the cord and reducing blood flow to the baby.
Choice A is correct because polyhydramnios, or excessive amniotic fluid around the fetus, can cause the cord to slip out when the membranes rupture.
Choice B is correct because breech presentation, or abnormal positioning of the baby, can make it easier for the cord to slip between and past the fetal feet and into the pelvis.
Choice C is correct because premature rupture of membranes, or breaking of the water before labor begins, can cause the cord to prolapse if the baby’s head is not well engaged in the pelvis.
Choice D is wrong because post-term pregnancy, or pregnancy that lasts longer than 42 weeks, is not a risk factor for umbilical cord prolapse. However, it can increase the risk of other complications such as fetal macrosomia, placental insufficiency and meconium aspiration.
Choice E is correct because multiple gestation, or having more than one baby in the uterus, can cause unstable lie, or frequent changes in the position of the baby. This can increase the risk of cord prolapse if the membranes rupture when the baby is not in a cephalic (head-down) position.

Correct Answer is C
Explanation
The correct answer is choice C. FHR of 80/min with severe variable decelerations.This indicates that the umbilical cord is prolapsed and compressed by the baby’s body, causing a decrease in blood and oxygen supply to the baby.A normal fetal heart rate is between 120 and 160 beats per minute.Severe variable decelerations are abrupt drops in the fetal heart rate that do not correspond to contractions.
Choice A is wrong because FHR of 160/min with accelerations is a normal finding that indicates a healthy baby.Accelerations are temporary increases in the fetal heart rate that usually occur with fetal movement or contractions.
Choice B is wrong because FHR of 120/min with early decelerations is also a normal finding that indicates a well-oxygenated baby.Early decelerations are gradual decreases in the fetal heart rate that mirror contractions and are caused by head compression.
Choice D is wrong because FHR of 140/min with late decelerations is an abnormal finding that indicates uteroplacental insufficiency, not cord prolapse.Late decelerations are gradual decreases in the fetal heart rate that occur after contractions and are caused by reduced blood flow to the placenta.
Correct Answer is A
Explanation
The correct answer is choice A. Push the presenting part upward with gloved fingers.This action can relieve cord compression and improve fetal oxygenation until an emergency cesarean section can be performed.
Choice B is wrong because pulling the cord gently to reduce tension can cause more damage to the umbilical vessels and increase the risk of fetal hemorrhage.
Choice C is wrong because clamping the cord with sterile forceps can cut off the blood supply to the fetus and cause fetal death.
Choice D is wrong because cutting the cord and tying it with sterile string can also cut off the blood supply to the fetus and cause fetal death.
Some additional information:
• A prolapsed umbilical cord is a rare but life-threatening obstetric emergency that occurs when the umbilical cord is abnormally positioned between the fetal presenting part and the cervix.
• The normal range of umbilical cord length is 40 to 60 cm.A longer cord can increase the risk of prolapse.
• The normal range of fetal heart rate is 110 to 160 beats per minute.A prolapsed cord can cause fetal bradycardia (slow heart rate) due to hypoxia.
