Diabetes Mellitus Q 4

---

The goal of preprandial blood glucose for those with type 1 diabetes mellitus is:

  

    A. <80 mg/dl

    B. <130 mg/dl

    C. <180 mg/dl

    D. >8%

    

    

Correct Answer: B. <130 mg/dl

According to the American Diabetes Association, the recommended preprandial glucose target for an adult with diabetes is between 80-130 mg/dl. In the management of diabetes, health care providers usually assess glycemic control with fasting plasma glucose (FPG) and premeal glucose measurements, as well as by measuring HbA1c.

Option A: The word postprandial means after a meal; therefore, PPG concentrations refer to plasma glucose concentrations after eating. Many factors determine the PPG profile. In nondiabetic individuals, fasting plasma glucose concentrations (i.e., following an overnight 8- to 10-h fast) generally range from 70 to 110 mg/dl.

Option C: This is the recommended postprandial (1-2 hours after eating) glucose target for an adult with diabetes. Elevated postprandial glucose (PPG) concentrations may contribute to suboptimal glycemic control. Postprandial hyperglycemia is also one of the earliest abnormalities of glucose homeostasis associated with type 2 diabetes and is markedly exaggerated in diabetic patients with fasting hyperglycemia.

Option D: An A1c value of >8 signifies that diabetes is not well controlled and a high risk for diabetes complication is possible. For an HbA1c test to classify as normal, or in the non-diabetic range, the value must be below 5.7 %. Anyone with an HbA1c value of 5.7 % to 6.4 % is considered to be prediabetic, while diabetes can be diagnosed with an HbA1c of 6.5% or higher.
