Correct Answer: B

Rationale: The correct answer is B: Iron and folic acid. Diamorphic anemia is characterized by the presence of both microcytic and macrocytic red blood cells, which can be caused by a deficiency in both iron and folic acid. Iron deficiency leads to microcytic anemia, while folic acid deficiency results in macrocytic anemia. Thiamine deficiency (Choice A) primarily affects the nervous system and does not directly cause diamorphic anemia. Liver enzymes deficiency (Choice D) does not directly lead to diamorphic anemia. Folic acid and thiamine deficiency (Choice C) can cause individual types of anemia but not diamorphic anemia.

Correct Answer: C

Rationale: The correct answer is C: Chest radiography. In cases of acute abdomen, a chest radiograph is essential to rule out conditions like pneumothorax, pleural effusion, or pneumonia which may present with similar symptoms. This helps in identifying potential causes of abdominal pain outside the abdomen. Abdominal radiograph (A) may not provide enough information for diagnosis. Contrast radiography (B) and ultrasonography (D) are not universally essential for all cases of acute abdomen and may not be appropriate in certain situations.

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: A

Rationale: The correct answer is A: Type A aortic aneurysm. Type A involves the ascending aorta, which is more critical due to proximity to the heart. Immediate surgical intervention is necessary to prevent catastrophic complications like aortic dissection or rupture. Choice B, Type B, usually involves the descending aorta and can often be managed through medical therapy initially. Choice C, Descending aneurysm, may not require immediate surgery unless symptomatic or rapidly expanding. Choice D, Symptomatic aneurysm, could refer to any type and would need further evaluation to determine the urgency of surgical intervention.

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.
