Correct Answer: C

Rationale: The correct statement is that Brachytherapy is an internal radiation therapy. Brachytherapy involves placing radioactive sources inside or near the tumor, delivering a high radiation dose to the targeted area while minimizing exposure to surrounding healthy tissues. Choices A and B are incorrect because pregnant nurses should not administer radiation therapy and brachytherapy does not make the patient radioactive. Choice D is incorrect as feces is not a source of radiation in teletherapy, and it does not require special disposal.

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: 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 care focuses on managing symptoms and improving the quality of life for clients with serious illnesses like cancer. Choice B is incorrect as palliative care can be provided alongside curative treatments. Choice C is incorrect because palliative care does not aim to prolong life at all costs; it focuses on improving the quality of life. Choice D is partially correct but does not fully capture the essence of palliative care, which includes symptom management and holistic support for the client and their family.

Correct Answer: A

Rationale: When a client is receiving rituximab, the nurse's priority assessment should be monitoring the blood pressure. Rituximab can lead to infusion-related reactions, such as hypotension. Therefore, assessing the client's blood pressure is crucial to detect and manage any potential adverse reactions promptly. While monitoring temperature, oral mucous membranes, and pain are essential aspects of care, they are not the priority when a client is receiving rituximab.
