Correct Answer: C

Rationale: The correct answer is C. A BUN level of 18 mg/dL is within the normal range; however, since cisplatin is nephrotoxic, it requires close monitoring. Elevated BUN levels can indicate impaired kidney function. Choices A, B, and D are within normal ranges and do not directly relate to cisplatin therapy or require immediate intervention.

Correct Answer: B

Rationale: The correct answer is B: Risk for Infection. Induction therapy for acute myeloid leukemia suppresses the immune system, making the patient highly susceptible to infections due to neutropenia. Preventing infections is crucial in these patients to avoid complications. Activity Intolerance (Choice A) may be a concern, but infection prevention is of higher priority. Acute Confusion (Choice C) and Risk for Spiritual Distress (Choice D) are not the immediate priorities in this situation.

Correct Answer: A

Rationale: The correct answer is A: Administer antiemetics 30 minutes before chemotherapy. Administering antiemetics before chemotherapy is crucial to prevent nausea rather than treating it after it occurs. This proactive approach helps in minimizing the side effects. Choice B, offering small, frequent meals, can be beneficial but is not the first intervention for severe nausea and vomiting. Choice C, encouraging rest after meals, may help but is not the priority when the client is experiencing severe symptoms. Choice D, instructing the client to use relaxation techniques, is not the first-line intervention for severe nausea and vomiting in a client receiving chemotherapy.

Correct Answer: A

Rationale: The correct answer is A: Tumor lysis syndrome (TLS). Tumor lysis syndrome is a potential complication after treatment for certain cancers, including non-Hodgkin lymphoma. The rapid breakdown of cancer cells in response to treatment can lead to metabolic abnormalities, such as hyperkalemia, hyperphosphatemia, hypocalcemia, and hyperuricemia, which can be life-threatening. Choice B, Syndrome of inappropriate antidiuretic hormone (SIADH), is not typically associated with non-Hodgkin lymphoma treatment. Choice C, Disseminated intravascular coagulation (DIC), is more commonly seen in conditions such as sepsis or trauma, not directly related to non-Hodgkin lymphoma treatment. Choice D, Hypercalcemia, is not a common complication following treatment for non-Hodgkin lymphoma.

Correct Answer: C

Rationale: The correct answer is C: 'Brachytherapy is an internal radiation therapy.' Brachytherapy involves the placement of radioactive sources inside or next to the area requiring treatment. This differs from teletherapy, which is external radiation therapy. Choice A is incorrect as pregnant individuals should avoid exposure to radiation. Choice B is incorrect because teletherapy does not make the patient radioactive; the radiation source is external. Choice D is incorrect as feces is not a significant source of radiation during teletherapy.
