Correct Answer: B

Rationale: Two positive responses on the CAGE questionnaire strongly suggest alcohol dependence. Choice A is incorrect as the CAGE questionnaire specifically targets alcohol abuse. Choice C is incorrect because one positive response is not enough to indicate alcohol addiction. Choice D is incorrect because alcohol dependence can be suggested with two positive responses, not all four.

Correct Answer: B

Rationale: The correct answer is B: Start intravenous fluids at a fast rate. In a client with pheochromocytoma, the highest priority intervention is to ensure adequate intravascular volume before initiating any other treatment. This helps prevent a sudden drop in blood pressure that can occur due to the release of catecholamines during tumor manipulation. While monitoring blood pressure frequently is essential, ensuring adequate intravascular volume takes precedence. Administering pain medication and antihypertensive medications are important but are not the highest priority in the initial management of pheochromocytoma.

Correct Answer: B

Rationale: The correct answer is B: "The client's ammonia level decreases." In hepatic encephalopathy, elevated ammonia levels contribute to neurological symptoms. Lactulose works by promoting the excretion of ammonia in the stool, leading to decreased serum ammonia levels. Therefore, a decrease in ammonia levels indicates that lactulose is effectively reducing ammonia buildup, improving hepatic encephalopathy symptoms. Choices A, C, and D are incorrect because improvement in level of consciousness, bowel movements, or normalization of liver enzymes may not directly reflect the effectiveness of lactulose in reducing ammonia levels and improving hepatic encephalopathy.

Correct Answer: D

Rationale: Administering a diuretic as prescribed is the most appropriate intervention to manage fluid volume in a client with ascites due to advanced liver disease. Diuretics help reduce fluid accumulation in the body, including the abdominal cavity where ascites occurs. Increasing sodium intake would worsen fluid retention, and encouraging more fluid intake can exacerbate ascites. Placing the client in a supine position does not directly address the fluid volume issue associated with ascites.

Correct Answer: B

Rationale: In this scenario, the nurse should explain the reason for using only non-narcotics. Following head trauma, non-narcotic medications such as acetaminophen are preferred to avoid masking symptoms of neurological changes, such as increased intracranial pressure, that could worsen after stronger pain medication. Administering an anti-inflammatory medication (Choice A) may not be appropriate as it may not address the severity of the headache. Consulting the healthcare provider about a stronger medication (Choice C) is important, but the immediate need is to educate the client on the rationale for using non-narcotic medications first. Administering a stronger medication as requested (Choice D) could potentially mask important symptoms and should be avoided in this situation.
