Oncology Test Bank

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: Clients are often overwhelmed by a sudden cancer diagnosis; therefore, it is best for the nurse to call the client at home the next day to review teaching. This approach allows the client time to process the information before the surgery. Choice B may be beneficial but is not the priority at this time. Providing written instructions (Choice C) is helpful but does not offer the personalized interaction needed. Reassuring the client (Choice D) is important but does not address the educational aspect of preoperative preparation.

Correct Answer: D

Rationale: The correct answer is D because the statement 'Chemotherapy is effective in killing all cancer cells' is incorrect. Chemotherapy does not kill all cancer cells and is not the same as radiation therapy. Chemotherapy targets rapidly dividing cells, including cancer cells, but it may not kill every single cancer cell. It is important for the student nurse to understand and communicate this distinction to the patient. Choices A, B, and C provide accurate information about teletherapy, brachytherapy, and chemotherapy, respectively, and do not require additional teaching.

Correct Answer: B

Rationale: The correct answer is B because the skin at the radiation site is sensitive to sunlight, and exposure can cause further damage. It is crucial to protect the area from direct sunlight to prevent skin irritation or burns. Choice A is incorrect as salt water typically does not pose a significant risk to the radiation site. Choice C is a positive and encouraging response but does not provide necessary advice for post-radiation care. Choice D, while important in some cases, is not directly related to the client's beach vacation after completing radiation treatments.

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.
