A maternal indication for the use of vacuum extraction is
Maternal exhaustion.
Failure to progress past 0 station.
A wide pelvic outlet.
A history of rapid deliveries.
The Correct Answer is A
Choice A reason:
Maternal exhaustion is a maternal indication for the use of vacuum extraction. Vacuum extraction is a technique that can assist the mother in delivering the baby when she is unable to push effectively or when pushing poses a risk to her health. Vacuum extraction can shorten the second stage of labor and reduce maternal fatigue and distress. According to the Cleveland Clinic, vacuum extraction might be indicated if "the mother can't push anymore, either due to exhaustion or a health condition.".
Choice B reason:
Failure to progress past 0 station is not a maternal indication for the use of vacuum extraction. The station refers to the position of the baby's head in relation to the mother's pelvis. 0 station means that the baby's head is at the level of the pelvic inlet, or the narrowest part of the pelvis. Vacuum extraction is usually not performed before the baby reaches +2 station, which means that the head is 2 cm below the pelvic inlet and visible at the vaginal opening. According to the American Academy of Family Physicians, vacuum extraction should not be attempted if "the fetal head is not engaged (above 0 station).".
Choice C reason:
A wide pelvic outlet is not a maternal indication for the use of vacuum extraction. The pelvic outlet is the lower part of the pelvis that forms the exit for the baby during delivery. A wide pelvic outlet means that there is more space for the baby to pass through, which can facilitate vaginal delivery and reduce the need for instrumental assistance. Vacuum extraction is more likely to be indicated when there is a narrow pelvic outlet, which can obstruct labor and cause fetal distress.
Choice D reason:
A history of rapid deliveries is not a maternal indication for the use of vacuum extraction. Rapid deliveries, also known as precipitous deliveries, are those that occur within 3 hours of the onset of labor. Rapid deliveries can pose risks to both the mother and the baby, such as excessive bleeding, umbilical cord prolapse, or birth trauma. However, vacuum extraction is not usually indicated in these cases, as it requires time and preparation to apply the device and monitor its effects. Vacuum extraction is more likely to be indicated when labor is prolonged or stalled in the second stage, and when there is a nonreassuring fetal heart rate.

Correct Answer is A
Explanation
The correct answer is c. Dehydration. A significantly indented anterior fontanelle in a newborn is most commonly a sign of dehydration.
Choice A reason:
Increased intracranial pressure: This statement is incorrect because increased intracranial pressure typically causes a bulging, not indented, fontanelle. Symptoms include irritability, vomiting, and a high-pitched cry.
Choice B reason:
Vernix caseosa: This statement is incorrect because vernix caseosa is a white, cheesy substance covering the skin of newborns, unrelated to fontanelle indentation. It serves as a protective layer for the baby’s skin.
Choice C reason:
Dehydration: This statement is correct. Dehydration in newborns can cause a sunken fontanelle due to the loss of fluid. Other signs include dry mouth, sunken eyes, and fewer wet diapers.
Choice D reason:
Cyanosis: This statement is incorrect because cyanosis refers to a bluish discoloration of the skin due to lack of oxygen, not related to fontanelle shape. It indicates issues with oxygenation or circulation.
Correct Answer is C
Explanation
Choice A reason:
Occasional uterine cramping when the infant nurses is a normal phenomenon that occurs as the uterus contracts and returns to its pre-pregnancy size. This is not a sign of infection or complication and does not need to be reported.
Choice B reason:
Descent of the fundus one fingerbreadth each day is also a normal finding that indicates the uterus is involuting properly. The fundus is the top of the uterus that can be felt through the abdomen. It should be at the level of the umbilicus immediately after delivery and then descend about one fingerbreadth (or 1 cm) each day until it reaches the pelvic brim by 10 days postpartum.
Choice C reason:
Reappearance of red lochia after it changes to serous is an abnormal sign that may indicate uterine atony, subinvolution, or retained placental fragments. Lochia is the vaginal discharge that occurs after childbirth, consisting of blood, mucus, and tissue. It usually changes from red to pink to brown to yellow-white over a period of several weeks. If it becomes red again, it may mean that there is bleeding from the uterus or infection in the endometrium. This should be reported to a health care provider as soon as possible.
Choice D reason:
Oral temperature that is 37.2 C (99 F) in the morning is within the normal range and does not indicate fever or infection. A slight elevation in temperature may occur due to dehydration, breast engorgement, or hormonal changes. This does not need to be reported unless it exceeds 38 C (100.4 F) or persists for more than 24 hours.
