Correct Answer: B

Rationale: Glycosylated hemoglobin (HbA1c) is the most accurate test for long-term management of blood glucose levels in individuals with diabetes mellitus. HbA1c reflects average blood glucose levels over the past 2-3 months, providing valuable information on the effectiveness of treatment and disease control. Postprandial blood glucose, glucose tolerance test, and fasting blood glucose are essential for monitoring blood glucose levels at specific times but do not offer the same insight into long-term disease management as HbA1c.

Correct Answer: C

Rationale: Using a hydrocolloid dressing is the appropriate care for a stage 2 pressure ulcer because it provides a moist healing environment, promotes healing, and helps to prevent infection. Cleaning the area with normal saline (Choice A) is important but not the primary treatment for a stage 2 pressure ulcer. Applying antibiotic ointment (Choice B) may not be necessary unless there is a sign of infection. Changing the dressing daily (Choice D) may disrupt the healing process and is not recommended unless the dressing is soiled or compromised.

Correct Answer: D

Rationale: The correct answer is D: Serum albumin 3.5 g/dL. A low serum albumin level indicates protein deficiency, which can be a complication of TPN therapy and requires prompt intervention. The other laboratory findings provided (serum calcium 8.5 mg/dL, blood glucose level 120 mg/dL, and serum sodium 138 mEq/L) are within normal ranges and do not specifically indicate complications related to TPN therapy.

Correct Answer: B

Rationale: The correct answer is to measure the client's abdominal girth daily. Measuring abdominal girth helps monitor for ascites, a common complication of cirrhosis. Limiting sodium intake is important in cirrhosis but there is no specific value given, making choice A less precise. Monitoring urine specific gravity is not directly related to cirrhosis management, making choice C incorrect. Encouraging the client to drink 3 liters of fluid per day may not be suitable for all patients with cirrhosis, especially those with fluid restrictions, so choice D is not the most appropriate intervention.

Correct Answer: A

Rationale: In patients with heart failure, monitoring daily weight is the most accurate method for assessing fluid balance. Weight gain can indicate fluid retention, a common issue in heart failure patients. Monitoring input and output (B) is essential but may not always accurately reflect fluid balance. Checking for edema (C) is important as it can indicate fluid accumulation, but daily weight monitoring is more precise. Monitoring blood pressure (D) is important in heart failure management but does not directly assess fluid balance.
