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 B
Explanation
Choice A) Increased urinary output: This is not a sign of sepsis in newborns. In fact, sepsis can cause reduced urinary output due to poor blood flow to the kidneys and dehydration.
Choice B) Hypothermia: This is a sign of sepsis in newborns. Sepsis can cause changes in temperature, often fever, but sometimes low temperature. Hypothermia can indicate a severe infection that affects the body's ability to regulate its temperature.
Choice C) Wakefulness: This is not a sign of sepsis in newborns. Sepsis can cause reduced activity and lethargy due to inflammation and organ dysfunction.
Choice D) Interest in feeding: This is not a sign of sepsis in newborns. Sepsis can cause reduced sucking and difficulty feeding due to poor appetite, nausea, vomiting, and abdominal distension.
Correct Answer is B
Explanation
Choice a) 100 to 120 is incorrect because this is too low for a normal newborn's heart rate. The heart rate of a newborn is influenced by factors such as gestational age, activity level, temperature, and health status. A full-term, quiet, alert newborn should have a heart rate between 120 and 160 beats per minute, which reflects their high metabolic rate and oxygen demand. A heart rate below 100 beats per minute may indicate bradycardia, which can be caused by hypoxia, hypothermia, or cardiac problems.
Choice b) 120 to 160 is correct because this is the normal range for a full-term, quiet, alert newborn's heart rate. The apical pulse is the best way to measure the heart rate of a newborn, as it reflects the actual contractions of the heart. The apical pulse can be auscultated at the fourth intercostal space on the left side of the chest, just below the nipple line. The nurse should count the apical pulse for a full minute, as it may vary with the respiratory cycle.
Choice c) 80 to 100 is incorrect because this is also too low for a normal newborn's heart rate. A full-term, quiet, alert newborn should have a heart rate between 120 and 160 beats per minute, which is higher than that of an adult or an older child. A heart rate below 100 beats per minute may indicate bradycardia, which can be caused by hypoxia, hypothermia, or cardiac problems.
Choice d) 150 to 180 is incorrect because this is too high for a normal newborn's heart rate. A full-term, quiet, alert newborn should have a heart rate between 120 and 160 beats per minute, which is lower than that of a preterm or a crying newborn. A heart rate above 160 beats per minute may indicate tachycardia, which can be caused by fever, infection, anemia, or hyperthyroidism.
