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: D

Rationale: The use of bed cradle in leg thrombosis management is to promote venous drainage. Elevating the legs on a bed cradle helps improve blood flow back to the heart, reducing swelling and preventing blood clots. Keeping the legs straight (A) is not the main purpose. Preventing embolism (B) is important but not the direct purpose of a bed cradle. Controlling body temperature (C) is unrelated to the use of a bed cradle for leg thrombosis.

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. In preeclampsia, epigastric pain is typically associated with liver and/or HELLP syndrome, not hyperacidity. Hyperacidity is more commonly seen in conditions like gastritis or peptic ulcers. Therefore, severe epigastric pain in preeclampsia is not related to hyperacidity. Other choices are not applicable as they do not provide relevant information to the question.

Correct Answer: A

Rationale: Rationale for Correct Answer (A): Shoulder dystocia is an impaction of the anterior shoulder after delivery of the head because the anterior shoulder gets stuck behind the pubic symphysis during childbirth. This can lead to serious complications for both the mother and the baby if not managed promptly. Summary of Incorrect Choices: B: Impaction of the posterior shoulder is not referred to as shoulder dystocia; it is the impaction of the anterior shoulder that causes the complication. C: Shoulder dystocia is not caused by a compound presentation of the fetus, which refers to a situation where more than one fetal part presents at the maternal pelvis simultaneously. D: Shoulder dystocia is indeed an emergency that requires immediate intervention, as delays can lead to birth injuries and complications. It does not resolve on its own and needs medical assistance.
