Diabetes Blood Sugar Management 3

Question 1

What blood glucose level (mg/dL) is generally used as the clinical threshold to define hypoglycemia in adults with diabetes?

Accepted Answer

Less than 70

Answer

A blood glucose below 70 mg/dL is the standard clinical threshold for hypoglycemia in adults with diabetes.

Question 2

A patient with type 2 diabetes consistently has high fasting glucose but acceptable daytime readings. What phenomenon does this most likely represent?

Accepted Answer

Dawn phenomenon

Answer

The dawn phenomenon is caused by early-morning surge of counter-regulatory hormones raising fasting glucose.

Question 3

Which food item is the BEST choice for quickly treating a blood glucose of 58 mg/dL?

Accepted Answer

4 oz of orange juice

Answer

Orange juice provides fast-acting simple carbohydrates that rapidly raise blood glucose, while fat slows absorption.

Question 4

What does 'time in range' (TIR) measure in continuous glucose monitoring?

Accepted Answer

Percentage of time glucose stays between 70–180 mg/dL

Answer

TIR represents the percentage of time a person's glucose remains within the target range of 70–180 mg/dL.

Question 5

Which condition can cause falsely LOW blood glucose readings on a standard glucometer?

Accepted Answer

Polycythemia (elevated red blood cell count)

Answer

Polycythemia can cause falsely low glucose readings because excess red blood cells consume glucose in the blood sample.
