Correct Answer: A

Rationale: The correct answer is A (Low ACTH and low cortisol) because in patients with an adrenal tumor causing Cushing's syndrome, the tumor autonomously produces cortisol, leading to suppression of ACTH secretion from the pituitary. This results in low ACTH levels and high cortisol levels. Choices B, C, and D are incorrect because they do not reflect the characteristic hormone levels seen in patients with an adrenal tumor causing Cushing's syndrome.

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: D

Rationale: The correct answer is D: Aspiration and culture of fluid. Given Jasmine's history of injection drug use, neck pain, inability to turn her neck, elevated temperature, and foul breath, there is a high suspicion of a deep neck space infection. Aspiration and culture of fluid from the affected area will help identify the causative organism and guide appropriate antibiotic therapy. This procedure is essential for definitive diagnosis and management of deep neck infections. A: Anteroposterior neck radiography is not the most appropriate initial diagnostic test for evaluating deep neck space infections as it may not provide detailed information on the extent or nature of the infection. B: CT scan of the neck may provide valuable information regarding the extent of the infection, but aspiration and culture of fluid are crucial for identifying the causative organism. C: White blood cell (WBC) differential may show signs of inflammation, but it does not provide specific information on the causative organism of the infection.

Correct Answer: C

Rationale: The correct answer is C: Placing client on Trendelenburg position. This helps prevent compression of the cord by moving the presenting part off the cord. Placing the client on all fours (choice A) may worsen cord compression. Application of fundal pressure (choice B) is contraindicated as it can further compress the cord. Labor augmentation with oxytocin (choice D) is not indicated in cord prolapse management as it does not address the immediate risk to the fetus. Trendelenburg position is the recommended intervention to alleviate cord compression and improve fetal oxygenation.
