If 10% contamination with 5% dextrose occurs, the glucose reading can increase by how many mg/dL?

Explanation:
When a glucose measurement is contaminated with a glucose-containing fluid, the result increases by the amount of glucose contributed by that contaminant. A 5% dextrose solution contains 5 g per 100 mL, which is 5000 mg/dL. If 10% of the sample volume is this solution, the contaminant adds 0.1 × 5000 = 500 mg/dL of glucose to the final mixture. Therefore, the reading can rise by about 500 mg/dL (assuming the original sample’s glucose is not already very high).
