The lie is defined as unstable when it keeps varying after

Correct Answer: A

Rationale: The correct answer is A (36 weeks gestation) because at this point in pregnancy, the fetus has reached a stable lie position. Before 36 weeks, fetal lie can vary due to the ample space in the uterus. After 36 weeks, the fetus tends to settle into a consistent head-down or breech position, making the lie stable. Choices B, C, and D are incorrect as they are past the point where the lie typically stabilizes, leading to less variability in fetal positioning.

Correct Answer: B

Rationale: The correct answer is B: FALSE. Severe epigastric pain in preeclampsia is not associated with hyperacidity but is more likely due to complications such as HELLP syndrome or liver involvement. Preeclampsia is characterized by high blood pressure and proteinuria, not hyperacidity. Therefore, severe epigastric pain in preeclampsia should not be attributed to hyperacidity. Other choices are not applicable.

Correct Answer: A

Rationale: The correct answer is A (36 weeks gestation) because at this stage, the fetal lie should stabilize into a consistent position, typically longitudinal. Before 36 weeks, fetal movement and position can vary frequently. Choices B, C, and D are incorrect as they are past the point where fetal lie should have stabilized. At 42 weeks gestation (Choice B), the baby is considered post-term, and fetal lie should have already been established. Similarly, Choices C (38 weeks) and D (40 weeks) fall within the expected range for fetal lie stabilization.

Correct Answer: D

Rationale: The correct answer is D, complete rupture of the uterus. This is an obstetric emergency due to the risk of severe bleeding and potential harm to both the mother and the fetus. A ruptured uterus can lead to life-threatening complications such as hemorrhage and shock. In contrast, options A, B, and C are not considered obstetric emergencies. Aftercoming head in breech, complete cephalic presentation, and complete breech presentation are normal variations in labor that do not typically require immediate intervention like a ruptured uterus does.

Correct Answer: A

Rationale: The correct answer is A because in cases of anteriorly situated placenta praevia, where the placenta partially or completely covers the cervix, a classical caesarean section is indicated to prevent severe bleeding during delivery. For choice B, a posteriorly situated placenta praevia does not necessitate a classical caesarean section. Choice C, gestation of more than 32 weeks, does not specifically indicate the need for a classical caesarean section. Choice D, aesthetic purpose on maternal request, is not a valid medical indication for a classical caesarean section.
