What are the recommended strategies for managing a breech presentation?

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: A

Rationale: The correct answer is A: Uterine rupture. This is the most significant risk associated with VBAC, where the scar from the previous cesarean section may tear during labor. This can lead to severe complications for both the mother and baby. Postpartum hemorrhage (B) and placenta previa (C) are potential risks in any pregnancy but are not specifically increased in VBAC. Therefore, the correct answer is A, as it directly relates to the unique risk of VBAC.

Correct Answer: B

Rationale: The correct answer is B: Assess fetal lung maturity. Amniotic fluid analysis measures the levels of substances like surfactant, which indicates lung maturity. This helps in determining if the fetus is ready for delivery. Other choices are incorrect because amniotic fluid analysis is not primarily used to detect fetal infections (A), determine fetal position (C), or assess placental health (D). These functions are typically achieved through other diagnostic tests or imaging techniques.

Correct Answer: D

Rationale: The correct answer is D because the placenta performs multiple functions in managing fetal waste products. It filters toxins, facilitates nutrient absorption, and removes carbon dioxide. The placenta acts as a barrier between the mother and the fetus, allowing for the exchange of nutrients and waste products. Therefore, all of the above choices are correct in describing the role of the placenta in managing fetal waste products. The other choices are incorrect because they do not encompass all the functions that the placenta serves in this context.

Correct Answer: A

Rationale: The correct answer is A: Frank breech, complete breech, footling breech. In a frank breech presentation, the baby's buttocks are aimed at the birth canal with legs flexed at the hips and extended at the knees. In a complete breech presentation, the baby's buttocks are aimed at the birth canal with legs flexed at the hips and knees. In a footling breech presentation, one or both of the baby's feet are positioned to come out first. These are the three main types of breech presentations. Choices B, C, and D do not accurately describe the different types of breech presentations, making them incorrect.
