The client is taking rosiglitazone (Avandia) for control of his diabetes. Which laboratory result should be reported to the physician? A. Blood glucose of \(110 \mathrm{mg} / \mathrm{dL}\) B. Creatinine level of \(3.0 \mathrm{mg} / \mathrm{dL}\) C. Blood urea nitrogen level of \(10 \mathrm{mg} / \mathrm{dL}\) D. White blood cell count of 8,000

To decide which laboratory value should be reported to the physician, we need to know the normal ranges for each of them: A. Blood glucose level: Normal range is between 70 - 140 mg/dL, depending on when it was measured (fasting or after a meal). Lower values may indicate hypoglycemia, and higher values may indicate hyperglycemia. B. Creatinine level: Normal range is between 0.84 - 1.21 mg/dL for men and 0.59 - 1.04 mg/dL for women. Higher values may indicate problems with kidney function. C. Blood urea nitrogen (BUN) level: Normal range is between 7 - 20 mg/dL. Higher values may also indicate problems with kidney function. D. White blood cell (WBC) count: Normal range is between 4,000 - 11,000 cells/mcL. Higher values may indicate an infection, and lower values may indicate a weakened immune system.

The laboratory values to watch out for in a diabetic patient taking rosiglitazone (Avandia) include: 1. Blood glucose levels: High values may indicate poor diabetes control, and very low values may indicate hypoglycemia. 2. Kidney function: Diabetes can lead to kidney damage. Creatinine and BUN levels can help assess the kidney function of the patient. 3. Infections: Diabetic patients are more prone to infections due to a weakened immune system. WBC count can be used to check for an infection.

A. Blood glucose of \(110 \mathrm{mg}/ \mathrm{dL}\): This value falls within the normal range for blood glucose levels. B. Creatinine level of \(3.0 \mathrm{mg}/ \mathrm{dL}\): This value is above the normal range and indicates a potential problem with kidney function. C. Blood urea nitrogen level of \(10 \mathrm{mg}/ \mathrm{dL}\): This value falls within the normal range for BUN levels. D. White blood cell count of 8,000: This value falls within the normal range for WBC count.

From the comparison in step 3, the only lab value that is out of the normal range is the creatinine level of \(3.0 \mathrm{mg}/ \mathrm{dL}\). This suggests a potential problem with kidney function, which is important to monitor in diabetic patients. Therefore, the answer is: B. Creatinine level of \(3.0 \mathrm{mg} / \mathrm{dL}\)
