Correct Answer: C

Rationale: The correct answer is C: chronic biliary inflammation or obstruction. Biliary cirrhosis is a condition characterized by scarring of the liver due to long-term damage to the bile ducts. Chronic biliary inflammation or obstruction can lead to the build-up of bile in the liver, causing damage over time. Acute viral hepatitis (choice A) typically does not directly cause biliary cirrhosis. Alcohol hepatotoxicity (choice B) is more commonly associated with alcoholic liver disease rather than biliary cirrhosis. Hepatic failure with prolonged venous hepatic congestion (choice D) may lead to liver cirrhosis, but it is not specific to biliary cirrhosis.

Correct Answer: A

Rationale: The correct answer is A: Maintain strict records of intake and output. This is the best way to assess fluid balance in a burn patient because it provides quantitative data on fluid intake and output, helping to monitor for fluid imbalance. Monitoring skin turgor (B) is unreliable in burn patients due to skin damage. Weighing the client daily (C) may not accurately reflect fluid balance changes. Checking for edema (D) is not specific to assessing fluid balance in burn patients. Maintaining intake and output records allows for precise monitoring and early detection of fluid shifts, making it the most appropriate choice.

Correct Answer: A

Rationale: The correct answer is A: 30 minutes before breakfast. Glyburide is a sulfonylurea medication that stimulates insulin release from the pancreas, enhancing glucose uptake. Taking it before breakfast ensures peak insulin levels coincide with the postprandial glucose spike, aiding in glucose control throughout the day. Option B is incorrect as taking it after dinner may lead to hypoglycemia during sleep. Option C is incorrect as midmorning is not an optimal time for a sulfonylurea dose. Option D is incorrect as taking it at bedtime may also increase the risk of hypoglycemia overnight.

Correct Answer: A

Rationale: The correct answer is A because in the four-point gait with partial weight bearing, the client should move the right crutch ahead first to provide support and stability, followed by the left foot. This sequence ensures proper weight distribution and balance. Moving both crutches together (B) may compromise stability. Moving the left crutch and right foot together (C) may cause uneven weight distribution. Moving both crutches and weaker leg together (D) may not provide adequate support for the weaker leg.

Correct Answer: B

Rationale: Step-by-step rationale: 1. CD4+ cells are a type of white blood cell crucial for immune function. 2. HIV targets and destroys CD4+ cells, leading to immune system damage. 3. Measuring CD4+ levels helps determine the extent of this damage. 4. Therefore, the correct answer is B. Summary: A: Presence of opportunistic infections - CD4+ levels indirectly affect susceptibility, but not measured for this purpose. C: Level of the viral load - Measured separately from CD4+ levels. D: Resistance to antigens - CD4+ levels do not directly indicate resistance.
