3 Multiple choice questions
- Plasma glucose measured 2hrs after 75g glucose load. Value greater than or equal to 200mg/dL indicative of DM if confirmed on another day by either an elevated FPG (above 126) or RPG value (200) or elevated glycosylated hemoglobin A1c.
- Irrespective of last meal or time of day. Glucose result of 200mg/dL or greater in presence of symptoms is presumptive of DM.
- 2hrs after 75g glucose load. Correlates to values between 140 and 199mg/dL. Value of less than 140mg/dL are considered normal.
3 True/False questions
Fasting Plasma Glucose (FPG) Assay → Fast for at least 8hrs. FPG result less than 110 mg/dL is normal, between 110 and 125 mg/dL imply impaired fasting glucose (IFG), values greater than or equal to 126 mg/dL indicate DM.
Oral Glucose Tolerance Test (OGTT) → Plasma glucose levels measured every 30mins for up to 3hrs. In diabetic, glucose levels start high and rise higher than in a normal patient. Levels also remain higher for a longer period of time.
-Line 1 is a normal response. What is Line 2 showing?
-Line 1 is normal response. What is line 3 showing?
-Line 1 is normal. What is line 4 showing? → No fasting required. 50g glucose load. Between 24-28 weeks gestation. If FPG >125mg/dL then GDM confirmed. If Peak plasma or 2hr glucose value >200mg/dL then GDM confirmed.
