Which maternal condition always necessitates delivery by cesarean section?
Ectopic pregnancy
Preeclampsia
Partial abruptio placentae
Total placenta previa
The Correct Answer is D
Choice a) Ectopic pregnancy is incorrect because this is not a condition that requires delivery by cesarean section. Ectopic pregnancy is a condition where the fertilized egg implants outside the uterus, usually in the fallopian tube. It is a life-threatening complication that can cause internal bleeding and rupture of the tube. Ectopic pregnancy cannot result in a viable baby and must be terminated as soon as possible, either by medication or surgery. Therefore, this response is irrelevant and inaccurate.
Choice b) Preeclampsia is incorrect because this is not a condition that always necessitates delivery by cesarean section. Preeclampsia is a condition where the blood pressure rises above 140/90 mmHg after 20 weeks of pregnancy, along with proteinuria and edema. It can cause complications such as eclampsia, HELLP syndrome, placental abruption, and fetal growth restriction. The only cure for preeclampsia is delivery of the baby and placenta, but the mode of delivery depends on several factors, such as the gestational age, the severity of the condition, the fetal status, and the maternal preference. Therefore, some women with preeclampsia may deliver vaginally, while
others may need a cesarean section.
Choice c) Partial abruptio placentae is incorrect because this is not a condition that always necessitates delivery by cesarean section. Abruptio placentae is a condition where the placenta separates from the uterine wall before delivery, causing vaginal bleeding, abdominal pain, uterine contractions, and fetal distress. It can be classified as partial or complete, depending on the extent of the separation. The mode of delivery for abruptio placentae depends on several factors, such as the degree of bleeding, the fetal viability, the cervical dilation, and the fetal position.
Therefore, some women with partial abruptio placentae may deliver vaginally, while others may need a cesarean section.
Choice d) Total placenta previa is correct because this is the only condition that always necessitates delivery by cesarean section. Placenta previa is a condition where the placenta covers part or all of the cervix, preventing normal delivery. It can be classified as marginal, partial, or total, depending on the degree of overlap. The mode of delivery for placenta previa depends on several factors, such as the type of previa, the amount of bleeding, the gestational age, and the fetal status. However, women with total placenta previa have no chance of delivering vaginally, as the placenta completely blocks the birth canal. Therefore, they must have a cesarean section to avoid hemorrhage and fetal compromise.

Correct Answer is C
Explanation
Choice a) Have the parent fold the infant's arms across the chest is incorrect because this is not a helpful way to calm a preterm infant. Folding the arms across the chest can restrict the infant's breathing and movement, and may increase their stress and discomfort. Preterm infants need gentle and supportive touch, not restraint or pressure.
Choice b) Encourage the parent to place the infant back in the warmer is incorrect because this is not a necessary or beneficial action for a preterm infant who is showing signs of overstimulation. Placing the infant back in the warmer can interrupt the bonding and attachment process between the parent and the infant, and may make the infant feel more isolated and insecure. Preterm infants need close and frequent contact with their parents, not separation or detachment.
Choice c) Encourage the parent to do kangaroo care is correct because this is an effective and evidence-based method of soothing and stabilizing a preterm infant who is experiencing overstimulation. Kangaroo care is a technique where the parent holds the infant skin-to-skin on their chest, providing warmth, comfort, and security. Kangaroo care can reduce the infant's stress hormones, lower their heart rate and blood pressure, improve their oxygenation and breathing, enhance their growth and development, and strengthen their bond with their parent.
Choice d) Cover the infant with a warm bed blanket is incorrect because this is not a sufficient or optimal way to comfort a preterm infant who is displaying signs of overstimulation. Covering the infant with a warm bed blanket can provide some warmth and protection, but it does not offer the same benefits as kangaroo care. A warm bed blanket cannot mimic the parent's heartbeat, voice, smell, and movement, which are essential for the infant's emotional and physiological well-being. Preterm infants need human touch and interaction, not just physical warmth.
Correct Answer is B
Explanation
Choice A: This is incorrect because acetylsalicylic acid (ASA), also known as aspirin, is not a cure for preeclampsia, but a preventive measure. ASA may reduce the risk of preeclampsia in some high-risk women by inhibiting platelet aggregation and improving blood flow to the placenta. However, ASA is not recommended for all pregnant women, as it may have adverse effects on the mother and the fetus, such as bleeding, premature closure of the ductus arteriosus, or fetal growth restriction.
Choice B: This is the correct answer because delivery of the fetus is the only definitive treatment for preeclampsia, as it eliminates the source of the placental factors that cause the condition. Preeclampsia is a multisystem disorder characterized by hypertension, proteinuria, and edema that occurs after 20 weeks of gestation. It is caused by abnormal placentation and endothelial dysfunction that lead to vasoconstriction, inflammation, and coagulation.
Delivery of the fetus and the placenta resolves these abnormalities and restores normal maternal physiology.
Choice C: This is incorrect because antihypertensive medications are not a cure for preeclampsia, but a symptomatic management. Antihypertensive medications may lower the blood pressure and reduce the risk of maternal complications, such as stroke, seizure, or organ damage. However, antihypertensive medications do not address the underlying cause of preeclampsia and do not improve fetal outcomes. Moreover, some antihypertensive medications are contraindicated in pregnancy due to their teratogenic effects.
Choice D: This is incorrect because magnesium sulfate is not a cure for preeclampsia, but a prophylaxis for eclampsia. Eclampsia is a severe complication of preeclampsia that involves seizures and coma. Magnesium sulfate is an anticonvulsant that prevents or treats eclamptic seizures by stabilizing neuronal membranes and reducing cerebral edema. However, magnesium sulfate does not lower blood pressure or improve renal function in preeclamptic women. It also has side effects such as nausea, flushing, headache, or respiratory depression.
