Correct Answer: B

Rationale: The correct answer is B: Mauriceau-Smellie-Veit. This method involves flexing the hips, extending the thighs, and applying suprapubic pressure to deliver the head in a complete breech presentation. This technique helps to avoid hyperextension of the neck and potential spinal cord injury. The Lovset maneuver (A) is used for delivering the arms in a breech presentation. The Burns Marshall method (C) involves performing an episiotomy and delivering the baby by flexion and traction on the legs. Gentle traction of the neck (D) is not recommended as it can cause spinal cord injury. Mauriceau-Smellie-Veit is the preferred method for safe delivery of the head in a complete breech presentation.

Correct Answer: D

Rationale: The correct answer is D, as all three choices are key indicators for cesarean section during labor. Fetal distress indicates the baby is not tolerating labor well. Failure to progress may lead to complications for the mother or baby. Breech presentation increases the risk of complications during vaginal delivery. Therefore, all three indicators warrant consideration for a cesarean section to ensure the safety of both the mother and the baby.

Correct Answer: A

Rationale: The correct answer is A: Temperature > 102°F. A high fever in the context of right lower quadrant colicky pain raises concern for ureteral colic, which is often caused by kidney stones. Fever may indicate infection or obstruction, requiring urgent medical attention. Choices B, C, and D are incorrect because they are common findings in cases of ureteral colic but are not as specific to raise the index of suspicion. White blood cell count elevation and hematuria are common with kidney stones, while vomiting is a common symptom due to severe pain. However, fever is a more concerning sign that necessitates prompt evaluation.

Correct Answer: B

Rationale: The correct answer is B: Inadequate surfactant levels. Surfactant is a substance that reduces surface tension in the alveoli, preventing their collapse. In respiratory distress syndrome, premature infants have insufficient surfactant production, leading to collapsed alveoli and difficulty breathing. Choice A is incorrect because it focuses on quality rather than quantity of surfactant. Choice C is incorrect as rib cage underdevelopment is associated with congenital conditions like thoracic dystrophy, not RDS. Choice D is incorrect as gradual alveolar rupture is not a known cause of RDS.

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.
