3 Multiple choice questions
- 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.
- Performed in place of OGTT (Oral Glucose Tolerance Test). For patients w/ poor absorption of orally administered glucose. [May have a glucose transporter problem in GI tract].
-Impaired Glucose Tolerance (IGT). Glucose level rises higher than 140 but is less than 200.
-Impaired Fasting Glucose (IFG).
3 True/False questions
Impaired glucose tolerance → 2hrs after 75g glucose load. Correlates to values between 140 and 199mg/dL. Value of less than 140mg/dL are considered normal.
What are the 3 criteria that lead to a diagnosis of diabetes? → - Fasting plasma glucose (FPG): 126 mg/dL or higher
- Plasma glucose 2 hr after 75 g glucose load (2hr PG): 200 mg/dL or higher
- A casual/random plasma glucose (PG) of 200 mg/dL or higher
- Confirmation is not required if the patient presents with either a hyperosmolar or ketotic crisis. The criteria apply to both adult and pediatric patients.
Two Hour Posprandial Plasma Glucose (2-H PP) → Irrespective of last meal or time of day. Glucose result of 200mg/dL or greater in presence of symptoms is presumptive of DM.
