Correct Answer: C

Rationale: The correct answer is multiple myeloma (choice C). Back pain is a common presenting symptom in multiple myeloma, especially in older patients. This malignancy can lead to bone pain due to bone destruction and fractures. Hodgkin disease (choice A) and Non-Hodgkin lymphoma (choice B) typically present with symptoms like painless lymph node enlargement, fever, and weight loss. Acute thrombocythemia (choice D) is characterized by an increase in platelet count but is not typically associated with the symptoms described by the patient.

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 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: 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: A

Rationale: The correct action by the nurse is to assess the client's gait and balance. Severe low back pain in a client with a history of prostate cancer may indicate spinal cord compression, a serious complication. Assessing gait and balance can help determine if there is any spinal cord involvement, which requires immediate medical attention. Asking about changes in urinary symptoms (choice B) is important to assess for possible urinary obstruction, but assessing gait and balance takes precedence due to the risk of spinal cord compression. Documenting the report thoroughly (choice C) is essential but not the most immediate action needed. Inquiring about recent activities (choice D) is not as critical as assessing for spinal cord involvement.
