Which blood glucose level range is considered indicative of prediabetes?
Fasting blood glucose level of 70 mg/dL.
Fasting blood glucose level of 100 mg/dL.
Random blood glucose level of 150 mg/dL.
Hemoglobin A1c level of 6.5%.
The Correct Answer is B
A fasting blood glucose level of 100 to 125 mg/dL is considered indicative of prediabetes, which is a condition where blood glucose levels are higher than normal but not high enough to be classified as diabetes.
Incorrect choices:
a. This choice is incorrect. A fasting blood glucose level of 70 mg/dL is within the normal range.
c. This choice is incorrect. A random blood glucose level of 150 mg/dL indicates hyperglycemia, but it is not indicative of prediabetes.
d. This choice is incorrect. An hemoglobin A1c level of 6.5% or higher is diagnostic of diabetes mellitus, not prediabetes.

Correct Answer is B
Explanation
The "three P's" of diabetes mellitus refer to polyuria (excessive urination), polydipsia (excessive thirst), and polyphagia (excessive hunger) due to the body's inability to effectively use glucose for energy.
Incorrect choices:
a. This choice is incorrect. Increased appetite, weight gain, and bloating are not characteristic of diabetes mellitus; rather, diabetes is associated with weight loss despite increased appetite (polyphagia).
c. This choice is incorrect. Pallor, palpitations, and pain are not specific manifestations of diabetes mellitus.
d. This choice is incorrect. Panic attacks, paranoia, and paresthesia are not typical clinical manifestations of diabetes mellitus.
Correct Answer is C
Explanation
The HbA1c test measures the average blood glucose level over the past 2-3 months and provides information about long-term glucose control. It is commonly used to monitor diabetes management and assess the effectiveness of treatment.
Incorrect choices:
a. This choice is incorrect. The fasting blood glucose test measures blood glucose levels after an overnight fast and provides information about current glucose levels, not long-term control.
b. This choice is incorrect. The OGTT measures the body's ability to clear glucose from the blood and is used to diagnose diabetes and impaired glucose tolerance, but it is not typically used for assessing long-term glucose control.
d. This choice is incorrect. The C-peptide test is used to assess insulin production by the pancreas and is not typically used to assess long-term glucose control.
