Which laboratory test is commonly used to monitor long-term glycemic control in individuals with diabetes mellitus by measuring average blood glucose levels over the past 2 to 3 months?
Fasting blood glucose test.
Oral glucose tolerance test (OGTT).
Hemoglobin A1c (HbA1c) test.
C-peptide test.
The Correct Answer is C
The Hemoglobin A1c (HbA1c) test measures the percentage of hemoglobin that is glycated, reflecting average blood glucose levels over the past 2 to 3 months. It is a valuable tool for assessing long-term glycemic control.
Incorrect choices:
a. This choice is incorrect. The fasting blood glucose test measures blood glucose levels after an overnight fast and provides a snapshot of current glucose levels, rather than long-term control.
b. This choice is incorrect. The oral glucose tolerance test (OGTT) measures how the body responds to a glucose load and is used to diagnose diabetes and impaired glucose tolerance, rather than monitor long-term control.
d. This choice is incorrect. The C-peptide test is used to assess insulin production by measuring the level of C-peptide, a byproduct of insulin production.

Correct Answer is A
Explanation
Type 1 diabetes mellitus is characterized by an autoimmune process in which the body's immune system destroys the pancreatic beta cells responsible for producing insulin. This results in an absolute deficiency of insulin, requiring exogenous insulin administration for glycemic control.
Incorrect choices:
b. This choice is incorrect. Type 2 diabetes mellitus is characterized by insulin resistance and impaired insulin secretion, rather than autoimmune destruction of beta cells.
c. This choice is incorrect. Gestational diabetes mellitus occurs during pregnancy and is not characterized by autoimmune destruction of beta cells.
d. This choice is incorrect. Prediabetes is a precursor to type 2 diabetes and involves impaired glucose tolerance, but it does not result from autoimmune destruction of beta cells.
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.
