Which diagnostic test is used to assess the body's ability to clear glucose from the blood and is commonly used to diagnose diabetes mellitus?
Fasting blood glucose test.
Hemoglobin A1c (HbA1c) test.
C-peptide test.
Oral glucose tolerance test (OGTT).
The Correct Answer is D
The OGTT measures the body's ability to clear glucose from the blood by drinking a glucose solution and measuring blood glucose levels at specific intervals. It is commonly used to diagnose diabetes mellitus.
Incorrect choices:
a. This choice is incorrect. The fasting blood glucose test measures blood glucose levels after an overnight fast and is not specifically used to assess glucose clearance.
b. This choice is incorrect. The HbA1c test measures average blood glucose levels over the past 2-3 months and is not specifically used to assess glucose clearance.
c. This choice is incorrect. The C-peptide test assesses insulin production by the pancreas and is not specifically used to assess glucose clearance.

Correct Answer is A
Explanation
Excessive thirst and frequent urination are classic symptoms of hyperglycemia in diabetes mellitus. These symptoms result from the body's attempt to eliminate excess glucose through urine.
Incorrect choices:
b. This choice is incorrect. Bradycardia and low blood pressure are not classic symptoms of hyperglycemia; they may be associated with other conditions.
c. This choice is incorrect. Weight gain and increased appetite are not typical symptoms of hyperglycemia; they may be observed in certain situations, but they are not characteristic of uncontrolled diabetes.
d. This choice is incorrect. Hypoglycemic episodes with confusion are symptoms of low blood sugar, not hyperglycemia.
Correct Answer is C
Explanation
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.
