Correct Answer: A

Rationale: The correct answer is A: Hair loss. Radiation therapy targets fast-growing cancer cells, which can also affect healthy cells such as those in hair follicles, leading to hair loss. This adverse effect occurs commonly with radiation therapy due to its impact on rapidly dividing cells. Hair loss is a well-known side effect that clients undergoing radiation therapy are often prepared for. The other choices, B: Fatigue, C: Stomatitis, and D: Vomiting, are also potential side effects of radiation therapy, but hair loss is specifically associated with radiation treatment due to its effect on hair follicles. Fatigue is a common side effect of cancer treatment in general, stomatitis is more commonly associated with chemotherapy, and vomiting can be a side effect of radiation but is not as directly linked as hair loss.

Correct Answer: C

Rationale: The correct answer is C: Abdominal girth. Serum albumin helps to increase oncotic pressure in the blood vessels, reducing fluid leakage into the abdomen and decreasing ascites, leading to a decrease in abdominal girth. Option A is incorrect because serum albumin does not directly affect urinary output. Option B is incorrect as serum albumin does not directly impact serum ammonia levels. Option D is incorrect because while serum albumin can help improve liver function, it does not directly treat hepatic encephalopathy.

Correct Answer: C

Rationale: During the evaluation phase, the nurse performs the key action of determining the effectiveness of the care plan. This involves assessing whether the client's goals are being met, if interventions are achieving the desired outcomes, and if any modifications are necessary. This step is crucial to ensure the care plan is successful and the client's needs are being addressed appropriately. Choice A is incorrect because diagnosing the client's condition is typically done in the assessment phase, not during evaluation. Choice B is incorrect as identifying nursing interventions is part of the planning phase. Choice D is incorrect as developing goals and outcomes is part of the planning phase as well. Overall, the evaluation phase focuses on assessing the effectiveness of the care plan rather than diagnosing, identifying interventions, or developing goals.

Correct Answer: C

Rationale: Elevating the head of the bed is the correct answer because it helps to promote venous drainage, reduce cerebral edema, and decrease intracranial pressure (ICP). By positioning the patient with the head elevated, gravity assists in preventing further increases in ICP. Encouraging fluids may lead to fluid overload and exacerbate cerebral edema. Providing physical therapy and frequent repositioning may increase ICP by causing unnecessary movement and potential strain on the patient's head and neck.

Correct Answer: B

Rationale: The correct answer is B: I.V. administration and urinary excretion. Lomustine is typically administered intravenously, allowing for rapid systemic distribution. The drug is metabolized in the liver and excreted primarily through the kidneys, thus the urinary route. This choice is correct as lomustine's pharmacokinetics align with this pattern. A: Oral administration and urinary - While some drugs are administered orally, lomustine is not typically given orally due to poor bioavailability. C: I.V. administration and fecal excretion - Lomustine is not primarily excreted via the feces, making this choice incorrect. D: Oral administration and fecal excretion - Lomustine is not primarily excreted via the feces, making this choice incorrect.
