Which of the following are contraindications for VBAC? (Select All that Apply.).
A prior vaginal delivery.
Gestation of 42 weeks.
Maternal obesity.
One prior cesarean delivery.
Macrosomic fetus.
Correct Answer : C,E
Choice A reason:
A prior vaginal delivery is not a contraindication for VBAC. In fact, it is a positive predictor of success for VBAC, as it indicates that the woman has a proven pelvis and can tolerate labor.
Choice B reason:
The gestation of 42 weeks is not a contraindication for VBAC. However, it is associated with an increased risk of stillbirth while awaiting spontaneous labor, which should be balanced against the risks of induction of labor or elective repeat cesarean.
Choice C reason:
Maternal obesity is a relative contraindication for VBAC. It is associated with a lower success rate of VBAC, a higher risk of uterine rupture, and a higher risk of maternal and neonatal complications. The decision to attempt VBAC in obese women should be made on a case-by-case basis by a senior obstetrician.
Choice D reason:
One prior cesarean delivery is not a contraindication for VBAC. Most women who have had one prior lower segment cesarean delivery are eligible for VBAC, as the risk of uterine rupture is low (0.5%) and the success rate is high (72-75%).
Choice E reason:
A macrosomic fetus is a relative contraindication for VBAC. It is associated with a lower success rate of VBAC, a higher risk of uterine rupture, and a higher risk of shoulder dystocia and birth trauma. The decision to attempt VBAC in women with suspected macrosomia should be made on a case-by-case basis by a senior obstetrician.

Correct Answer is B
Explanation
Choice A reason:
Using illicit drugs is not a known cause of congenital hip dysplasia. Illicit drugs may have other harmful effects on the baby, but they do not affect the formation of the hip joint.
Choice B reason:
Unknown. The exact cause of congenital hip dysplasia is not clear. Both genetic and environmental factors seem to play a role in the development of the disorder. Some risk factors include being female, firstborn, breech position, family history, and tight swaddling.
Choice C reason:
Being in nursing school is not a cause of congenital hip dysplasia. This is an irrelevant and incorrect choice.
Choice D reason:
Drinking too much is not a cause of congenital hip dysplasia. Alcohol consumption during pregnancy may increase the risk of fetal alcohol syndrome and other complications, but it does not affect the formation of the hip joint.
Correct Answer is A
Explanation
Choice A reason:
FAS is caused by alcohol, and NAS is caused by opioids. This is the correct answer because FAS stands for fetal alcohol syndrome, which is a condition that affects the development of a baby when the mother drinks alcohol during pregnancy. NAS stands for neonatal abstinence syndrome, which is a group of problems that can happen when a baby is exposed to opioid drugs for a length of time while in their mother's womb.
Choice B reason:
FAS and NAS are both incurable. This is incorrect because FAS and NAS are not diseases, but conditions that result from prenatal exposure to substances. FAS and NAS can cause various physical, mental, and behavioral problems in the baby, some of which may be permanent, but others may be improved with early intervention and treatment.
Choice C reason:
FAS is caused by analgesics and NAS is caused by NSAIDs. This is incorrect because analgesics are painkillers, and NSAIDs are nonsteroidal anti-inflammatory drugs. Neither of these types of drugs is known to cause FAS or NAS. However, some analgesics, such as codeine and oxycodone, are opioids and can cause NAS if used by pregnant women.
Choice D reason:
FAS and NAS are both curable. This is incorrect because FAS and NAS are not diseases, but conditions that result from prenatal exposure to substances. FAS and NAS can cause various physical, mental, and behavioral problems in the baby, some of which may be permanent, but others may be improved with early intervention and treatment. However, there is no cure for FAS or NAS.
