Convulsions in amniotic fluid embolism are confused for:

Correct Answer: D

Rationale: The correct answer is D: Postpartum eclampsia. In amniotic fluid embolism, convulsions can mimic postpartum eclampsia due to similarities in symptoms such as seizures and hypertension. However, the key differentiator is the timing of onset - postpartum eclampsia occurs after delivery, while amniotic fluid embolism typically occurs during labor or immediately postpartum. Choices A, B, and C are incorrect as they do not align with the timing and clinical presentation of amniotic fluid embolism. Antepartum eclampsia occurs before delivery, stroke presents with neurological deficits, and pre-existing epilepsy is a chronic condition unrelated to the immediate postpartum period.

Correct Answer: A

Rationale: The correct answer is A (1000-500 gm) because extremely low birth weight babies are typically defined as those weighing less than 1000 grams (1kg) at birth. This range specifically includes weights below 1000 grams, making it the most accurate choice. Choice B (500-1500 gm) is incorrect because it includes weights above the threshold for extremely low birth weight (1000 gm). Choice C (1001-1500 gm) is incorrect because it excludes babies weighing less than 1000 gm, which are considered extremely low birth weight. Choice D (1500-2000 gm) is also incorrect as it includes weights above the range for extremely low birth weight babies.

Correct Answer: D

Rationale: The correct answer is D because Down syndrome is primarily caused by trisomy of chromosome 21. This means there is an extra copy of chromosome 21, leading to the characteristic features of the syndrome. Mosaicism and translocation of chromosome 21 can also result in Down syndrome, albeit less frequently. Option A includes deletion, which is not a common cause of Down syndrome. Option B lists duplication, which is not a typical mechanism for Down syndrome. Option C includes deletion and mosaicism, but trisomy is the main cause of Down syndrome, making option D the most accurate choice.

Correct Answer: A

Rationale: The correct answer is A: External cephalic version. This procedure involves manually manipulating the baby from a breech position to a head-down position. It is recommended as a safe and effective way to manage breech presentations, reducing the need for a cesarean section. Immediate cesarean (B) is not always necessary and should be reserved for specific medical reasons. Pelvic X-ray (C) is not routinely recommended for managing breech presentations. Induction of labor (D) is not the primary strategy for managing breech presentations, as it does not address the positioning of the baby.

Correct Answer: D

Rationale: The correct answer is D because both statements A and C are true. Older mothers have a higher risk of developing preeclampsia due to age-related complications. Additionally, advanced maternal age is associated with an increased likelihood of requiring a cesarean section due to factors like decreased uterine elasticity. Statement B is incorrect as younger mothers are not at higher risk of miscarriage compared to older mothers. This is because maternal age is not a significant factor in miscarriage risk.
