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.

Answer and Explanation

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 D

Explanation

Chronic hyperglycemia in diabetes mellitus can lead to damage of small blood vessels and nerves, resulting in neuropathy characterized by numbness, tingling, and pain in the extremities.

Incorrect choices:

a. This choice is incorrect. Nausea, vomiting, and abdominal pain are not typically manifestations of neuropathy in diabetes mellitus.

b. This choice is incorrect. Blurred vision and vision loss are associated with diabetic retinopathy, a microvascular complication, not nerve damage.

c. This choice is incorrect. Impaired wound healing and increased susceptibility to infections are related to the effects of hyperglycemia on blood flow and immune function, rather than nerve damage.

A. Diabetic ketoacidosis (DKA). B. Diabetic nephropathy. C. Diabetic neuropathy. D. Peripheral arterial disease (PAD).

Correct Answer is D

Explanation

Peripheral arterial disease (PAD) is a chronic complication of diabetes mellitus that results from the thickening and narrowing of small blood vessels, leading to reduced blood flow to the lower extremities. This can cause symptoms such as leg pain, numbness, and poor wound healing.

Incorrect choices:

a. This choice is incorrect. Diabetic ketoacidosis (DKA) is an acute complication characterized by high blood glucose levels, ketosis, and metabolic acidosis.

b. This choice is incorrect. Diabetic nephropathy is a chronic complication that affects the kidneys and can lead to impaired kidney function.

c. This choice is incorrect. Diabetic neuropathy refers to nerve damage due to diabetes and can cause symptoms such as tingling, pain, and loss of sensation in the extremities.
