Correct Answer: B

Rationale: The correct answer is B: Glycosylated hemoglobin (HbA1c). The glycosylated hemoglobin test measures average blood glucose levels over the past 2-3 months, providing an indication of long-term glycemic control in clients with diabetes. Choice A, postprandial blood glucose, reflects blood sugar levels after a meal and does not provide a long-term view. Choice C, glucose tolerance test, evaluates the body's ability to process sugar but does not offer a continuous assessment like the HbA1c test. Choice D, fasting blood glucose, measures blood sugar levels after a period of fasting, which is more indicative of immediate glycemic status rather than long-term management.

Correct Answer: C

Rationale: In acute pancreatitis, the nurse should expect elevated blood glucose levels. This is due to impaired insulin production by the inflamed pancreas. While serum amylase and lipase levels are typically elevated in acute pancreatitis, blood glucose levels are also affected due to the pancreatic dysfunction. Therefore, choices A and B are incorrect. Elevated calcium levels are not typically associated with acute pancreatitis, making choice D incorrect.

Correct Answer: A

Rationale: The correct answer is A. Clients with chronic kidney disease often develop anemia due to reduced erythropoietin production, leading to decreased red blood cell production. Iron supplementation is frequently required to enhance red blood cell production. Choices B, C, and D are incorrect because in chronic kidney disease, there is a need to restrict phosphorus intake, control carbohydrate intake for blood sugar management, and monitor electrolytes and fluid balance rather than blood glucose levels.

Correct Answer: B

Rationale: The correct action for the nurse to take when assisting with the insertion of a nontunneled percutaneous central venous catheter into the subclavian vein is to place the client in Trendelenburg position. This position helps distend the veins and reduces the risk of air embolism during the insertion procedure. Option A, positioning the client in a high-Fowler's position, would not be appropriate as it does not facilitate venous distention. Option C, placing a rolled towel under the client's neck, is not directly related to the procedure and does not serve a specific purpose in this context. Option D, assisting the client into a side-lying position, is also not the correct choice as Trendelenburg position is preferred for this procedure to aid in vein distention.

Correct Answer: D

Rationale: The correct answer is D. Swelling in the feet can indicate worsening heart failure due to fluid retention, and clients should report this to their healthcare provider immediately. Choices A, B, and C are incorrect because weighing once a week may not provide timely information on fluid retention, timing of diuretic medication is usually advised in the morning to prevent nocturia, and limiting fluid intake to 3 liters per day may not be appropriate for all clients with heart failure.
