Which laboratory result should a nurse assess as a normal value for a two-hour postprandial glucose tolerance test?

• A. 140 mg/dl.
• B. 160 mg/dl.
• C. 180 mg/dl.
• D. 200 mg/dl.

Answer: (A)

In a two-hour postprandial glucose tolerance test, a normal blood glucose level is considered to be less than 140 mg/dl. This threshold indicates that the body is effectively processing the glucose from the meal consumed. Values above this level suggest potential glucose intolerance or diabetes. Specifically, a reading of 140 mg/dl or below typically indicates normal glycemic control after eating. Therefore, assessing a level of 140 mg/dl as normal aligns with established guidelines for glucose testing. Recognizing this helps healthcare professionals identify patients who may need further evaluation or management of their blood sugar levels.
