Which of the following best describes type 1 diabetes mellitus?
Insulin resistance and relative insulin deficiency.
Onset typically occurs in adulthood.
Caused by an autoimmune destruction of pancreatic beta cells.
Mainly managed through oral hypoglycemic agents.
The Correct Answer is C
Type 1 diabetes mellitus is characterized by an autoimmune destruction of pancreatic beta cells, leading to an absolute insulin deficiency. It is not primarily characterized by insulin resistance (choice a) and is not typically diagnosed in adulthood (choice b). Oral hypoglycemic agents (choice d) are not the mainstay of treatment for type 1 diabetes.

Incorrect choices:
a. This choice is incorrect. Metformin primarily improves insulin sensitivity and reduces hepatic glucose production.
b. This choice is incorrect. Glipizide stimulates insulin secretion from pancreatic beta cells.
d. This choice is incorrect. Insulin detemir is a long-acting basal insulin used in insulin therapy.
Correct Answer is C
Explanation
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.
