What is an occult cord prolapse?
The cord is in front of the fetal head, but not visible or palpable
The cord is hidden, often next to but not in front of the fetal head.
The cord is visible or palpable outside of the vagina
The cord is wrapped around the fetal neck or body
The Correct Answer is B
The correct answer is choice B. The cord is hidden, often next to but not in front of the fetal head. This is called an occult cord prolapse and it occurs when the umbilical cord descends alongside–but not past–the presenting part of the baby. Occult cords can occur with ruptured or intact membranes. They can cause hypoxia, brain injury, and permanent disability in a baby, so medical personnel must address them rapidly and appropriately.
Choice A is wrong because it describes an overt cord prolapse, which means that the cord slips down into your cervix and vagina ahead of your baby during delivery. This is a medical emergency that can cut off your baby’s blood and oxygen supply during delivery.
Choice C is wrong because it describes a visible cord prolapse, which is a type of overt cord prolapse where the cord is visible or palpable outside of the vagina. This is also a medical emergency that requires immediate delivery.
Choice D is wrong because it describes a nuchal cord, which means that the cord is wrapped around the fetal neck or body. This is not a prolapse, but it can cause complications such as reduced blood flow, fetal distress, or umbilical cord strangulation.

Correct Answer is C
Explanation
This is a condition where there is too little amniotic fluid around the fetus.This increases the risk of umbilical cord prolapse because the cord can easily slip past the presenting part of the fetus and into the cervix or vagina.
This can cause fetal hypoxia and distress due to compression or occlusion of the cord.
Choice A. Transverse lie is wrong because this is a condition where the fetus lies horizontally across the uterus.This can increase the risk of cord prolapse if the membranes rupture and the cord descends alongside or before the fetus.
Choice B. Macrosomia is wrong because this is a condition where the fetus is larger than average.This can decrease the risk of cord prolapse because the presenting part of the fetus is more likely to fill the pelvis and prevent the cord from slipping past.
Choice D. Placenta previa is wrong because this is a condition where the placenta covers part or all of the cervix.This can increase the risk of bleeding during labor, but not necessarily cord prolapse.
Correct Answer is B
Explanation
The correct answer is choice B. Umbilical cord compression.Variable decelerations are the most common type of fetal deceleration and they are caused by compression of the umbilical cord.They vary in shape, duration, and intensity and may not have a constant relationship with uterine contractions.
Choice A is wrong because uteroplacental insufficiency is the cause of late decelerations, not variable decelerations.Uteroplacental insufficiency is a decrease in the blood flow to the placenta that reduces the amount of oxygen and nutrients transferred to the fetus.
Choice C is wrong because maternal hypotension is one of the possible causes of late decelerations, not variable decelerations.Maternal hypotension can reduce the uteroplacental blood flow and cause fetal hypoxia.
Choice D is wrong because fetal head compression is the cause of early decelerations, not variable decelerations.Early decelerations are benign and uniform in shape and they occur when the fetal head is pressed against the cervix during a uterine contraction.
