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 A
Explanation
Choice A reason:
This is a caput succedaneum, which is a collection of fluid from pressure of the vacuum extractor. This is the correct answer because caput succedaneum is a swelling of the scalp that crosses the suture line and is caused by prolonged pressure on the baby's head during delivery. It can also result from the use of vacuum extraction or forceps. Caput succedaneum is harmless and usually resolves on its own within a few days.
Choice B reason:
This is erythema toxicum, which is a transient allergic reaction that causes edema in the skin. This is incorrect because erythema toxicum is a common rash that affects newborns, but it does not cause swelling of the scalp or cross the suture line. It appears as red blotches with small white or yellow bumps that can occur anywhere on the body. Erythema toxicum is also harmless and usually disappears within a week.
Choice C reason:
This is a cephalhematoma, which will resolve on its own in 3 to 5 days. This is incorrect because cephalhematoma is bleeding under the scalp that does not cross the suture line and is caused by ruptured blood vessels in the scalp. It can also result from the use of vacuum extraction or forceps. Cephalhematoma may take weeks or months to resolve and can increase the risk of jaundice.
Choice D reason:
This is a Mongolian spot, which is found on many newborns. This is incorrect because Mongolian spots are bluish-gray patches of skin that are present at birth and are caused by melanocytes (pigment-producing cells) that are trapped in the deeper layers of the skin. They are not related to swelling or pressure on the head and usually fade by age 5.
Correct Answer is A
Explanation
Choice A reason:
Expressions of excitement are an expected finding during the taking-in phase of maternal postpartum adjustment. This is the time of reflection for the woman because, within the 2 to 3-day period, the woman is passive and dependent on her healthcare provider or support person with some of the daily tasks and decision-making. The woman prefers to talk about her experiences during labor and birth and also her pregnancy. The taking-in phase provides time for the woman to regain her physical strength and organize her rambling thoughts about her new role.
Choice B reason:
Lack of appetite is not an expected finding during the taking-in phase of maternal postpartum adjustment. The woman is oriented primarily to her own needs and she primarily focuses on sleeping and eating. She may have increased appetite due to the energy expenditure during labor and delivery. Lack of appetite may indicate postpartum depression or other complications.
Choice C reason:
Eagerness to learn newborn care skills is not an expected finding during the taking-in phase of maternal postpartum adjustment. This is more characteristic of the taking-hold phase, which starts 2 to 4 days after delivery. The woman starts to initiate actions on her own and make decisions without relying on others. She starts to focus on the newborn instead of herself and begins to actively participate in newborn care.
Choice D reason:
Focus on the family unit and its members is not an expected finding during the taking-in phase of maternal postpartum adjustment. This is more indicative of the letting-go phase, which occurs when the woman finally accepts her new role and gives up her old role. This is the phase where postpartum depression may set in. Readjustment of the relationship is needed for an easy transition to this phase.
