Which of the following is a potential consequence of prolonged hyperglycemia in diabetes mellitus?
Hypoglycemic episodes and dizziness.
Increased cellular glucose uptake and energy production.
Formation of advanced glycation end products (AGEs) leading to tissue damage.
Enhanced insulin sensitivity and improved glucose control.
The Correct Answer is C
Prolonged hyperglycemia in diabetes can lead to the formation of advanced glycation end products (AGEs), which contribute to tissue damage, inflammation, and complications such as neuropathy and nephropathy.
Incorrect choices:
a. This choice is incorrect. Hypoglycemic episodes are associated with low blood sugar, not prolonged hyperglycemia.
b. This choice is incorrect. Increased cellular glucose uptake and energy production would not be consequences of prolonged hyperglycemia; rather, hyperglycemia impairs cellular glucose uptake.
d. This choice is incorrect. Prolonged hyperglycemia leads to insulin resistance, not enhanced insulin sensitivity.

A fasting blood glucose level of 126 mg/dL or higher on two separate occasions is indicative of diabetes mellitus. A level of 110 mg/dL is within the normal range, and levels of 90 mg/dL and 100 mg/dL are also normal.
Incorrect choices:
a. This choice is incorrect. A fasting blood glucose level of 110 mg/dL is within the normal range.
c. This choice is incorrect. A fasting blood glucose level of 90 mg/dL is within the normal range.
d. This choice is incorrect. A fasting blood glucose level of 100 mg/dL is within the normal range.
Correct Answer is B
Explanation
Type 2 diabetes mellitus is characterized by insulin resistance, where cells do not effectively respond to insulin, and relative insulin deficiency due to impaired beta cell function.
Incorrect choices:
a. This choice is incorrect. Type 1 diabetes mellitus involves autoimmune destruction of beta cells and an absolute insulin deficiency.
c. This choice is incorrect. Gestational diabetes mellitus occurs during pregnancy and may involve a combination of insulin resistance and impaired insulin secretion.
d. This choice is incorrect. Secondary diabetes mellitus is caused by other medical conditions or factors, not primarily by insulin resistance and relative insulin deficiency.
