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 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: D

Rationale: Inspiratory stridor is the correct answer as it suggests airway obstruction, a critical issue requiring immediate intervention. Frequent swallowing (choice A) is a common postoperative finding and does not indicate an immediate need for intervention. The presence of mucous membranes (choice B) is a normal finding and does not require immediate intervention. Bubbling in the water-seal chamber (choice C) of a chest tube drainage system is an expected finding and indicates proper functioning of the system, not an immediate need for intervention.

Correct Answer: D

Rationale: The correct answer is D, Peripheral neuropathy. This can be a serious and dose-limiting side effect of chemotherapy for Hodgkin lymphoma. Peripheral neuropathy can cause tingling, numbness, and pain in the hands and feet due to nerve damage. While nausea and vomiting, alopecia, and fatigue are common side effects of chemotherapy, they are not typically as concerning or dose-limiting as peripheral neuropathy in the context of Hodgkin lymphoma treatment.
