Correct Answer: A

Rationale: The correct answer is to elevate the head of the bed. Elevating the head of the bed can help reduce the pressure on the superior vena cava, improve venous return, and facilitate breathing in clients with superior vena cava syndrome. Administering steroids (Choice B) may be necessary in some cases, but it is not the priority in the immediate care of a client with superior vena cava syndrome. Providing supplemental oxygen (Choice C) may help improve oxygenation but does not directly address the underlying issue of venous congestion. Administering diuretics (Choice D) may be contraindicated as it can further decrease preload and worsen the condition in superior vena cava syndrome.

Correct Answer: C

Rationale: The correct answer is C: Muscle weakness. In patients with multiple myeloma who have developed hypercalcemia, monitoring for muscle weakness is crucial. Hypercalcemia can lead to muscle weakness due to its effects on neuromuscular function. Choice A, increased heart rate, is more commonly associated with conditions like dehydration or anxiety rather than hypercalcemia. Choice B, decreased urine output, is commonly seen in conditions leading to acute kidney injury rather than hypercalcemia. Choice D, hypertension, is not a typical symptom of hypercalcemia and is more commonly associated with other conditions like uncontrolled high blood pressure.

Correct Answer: C

Rationale: The correct answer is that normal cells undergo apoptosis, which is a programmed cell death process essential for maintaining tissue homeostasis. Choice A is incorrect as normal cells do have specific functions. Choice B is incorrect as the size of the nucleus may vary but is not a defining characteristic of normal cells. Choice D is incorrect as the color of the nucleus is not a standard characteristic of normal cells.

Correct Answer: D

Rationale: The course of polycythemia vera can be best ascertained by monitoring the patient's hematocrit, which should remain below 45%. Hematocrit levels are a key indicator in assessing the progression of the disease. Choices A, B, and C are not the most appropriate methods for gauging the course of polycythemia vera. Monitoring the color of the patient's palms and face, or their response to erythropoietin injections, may not provide an accurate reflection of the disease's progression. Similarly, while erythrocyte sedimentation rate can be affected in polycythemia vera, it is not the primary marker for monitoring the disease's course.

Correct Answer: A

Rationale: The correct answer is A: Palliative. Palliative surgery is aimed at relieving symptoms and improving quality of life when a cure is not possible. In this scenario, where the cancer has recurred and metastasized, the goal of surgery would be to alleviate symptoms rather than to cure the disease. Choices B, C, and D are incorrect because reconstructive surgery aims to restore function or appearance, salvage surgery aims to remove or salvage tissue to prevent further complications, and prophylactic surgery aims to prevent the development of a condition rather than treat its progression.
