Question

If fasting glucose was 90 mg\dL, which of the following 2-hour postprandial glucose results would mostt closely represent normal glucose metabolism?

a. 55 mg\dL (3.0 mmol\L)
b. 100 mg\dL (5.5 mmol\L)
c. 180 mg\dL (9.9 mmol\L)
d. 260 mg\dL (14.3 mmol\L)

Answer 1

The most representative 2-hour postprandial glucose result for normal glucose metabolism with a fasting glucose of 90 mg/dL would be 100 mg/dL (5.5 mmol/L), which is within the normal range post-meal.

Step-by-step explanation:

The 2-hour postprandial glucose result that would most closely represent normal glucose metabolism in a person with a fasting glucose level of 90 mg/dL is 100 mg/dL (5.5 mmol/L). This result is within the normal range for blood glucose levels after a meal, which is between 100-140 mg/dL (5.5-8.0 mmol/L), according to standard medical guidelines.

A result of 55 mg/dL indicates hypoglycemia, which is abnormally low blood sugar, while results like 180 mg/dL and 260 mg/dL suggest hyperglycemia, which can be indicative of impaired glucose tolerance or diabetes if consistently observed. Hence, the correct option is b. 100 mg/dL (5.5 mmol/L).
