Which diagnostic test for diabetes mellitus provides a measure of glucose levels for the previous 8 to 12 weeks?

Glycosylated hemoglobin (HbA1C)

Oral glucose tolerance test

Postprandial glucose test

Fasting blood sugar (FSBS)

Answer and Explanation

The Correct Answer is A

A. Glycosylated hemoglobin (HbA1C): The HbA1C test provides an average measure of blood glucose levels over the past 8 to 12 weeks. It reflects the percentage of hemoglobin that has glucose attached to it, giving an indication of long-term blood sugar control.

B. Oral glucose tolerance test: This test measures the body’s response to glucose by checking blood sugar levels after drinking a sugary solution. It does not provide an average of blood glucose over weeks, but rather, it assesses blood glucose levels at specific time points after glucose ingestion.

C. Postprandial glucose test: This test measures blood glucose levels after eating a meal, typically 1 to 2 hours later. It provides information about immediate glucose levels, not long-term glucose control over weeks.

D. Fasting blood sugar (FSBS): This test measures blood glucose levels after fasting for at least 8 hours. It gives a snapshot of current glucose levels but does not provide a measure of glucose control over weeks.

Correct Answer is D

Explanation

A. Diarrhea: This is more commonly associated with hyperthyroidism, where increased metabolism can lead to more frequent bowel movements. It is not typically a sign of hypothyroidism, which often leads to constipation.

B. Tachycardia: Tachycardia (increased heart rate) is a common sign of hyperthyroidism due to the increased metabolic rate. In hypothyroidism, the heart rate often slows down, leading to bradycardia.

C. Weight loss: Weight loss is typically associated with hyperthyroidism, where the increased metabolic rate causes the body to burn more calories. In contrast, hypothyroidism generally leads to weight gain due to a slowed metabolism.

D. Cold intolerance: Cold intolerance is a common symptom of hypothyroidism. People with hypothyroidism have a slowed metabolism, leading to difficulty regulating body temperature, and they often feel unusually cold, even in warm environments.

A. lodine will be administered in the 2 weeks before surgery to increase the level of thyroid hormone being released into the bloodstream. B. Salt should be avoided during the 2 weeks before surgery. C. Medications will be administered to increase the vascularity of the gland before D. Medications will be administered in the 2 weeks before surgery to reduce the vascularity of the gland.

Correct Answer is D

Explanation

A. Iodine will be administered in the 2 weeks before surgery to increase the level of thyroid hormone being released into the bloodstream: Iodine is used to reduce thyroid hormone production and decrease vascularity of the thyroid gland, not to increase it before surgery.

B. Salt should be avoided during the 2 weeks before surgery: There is no requirement to avoid salt before a thyroidectomy, and it is not part of the standard preoperative care for this procedure.

C. Medications will be administered to increase the vascularity of the gland before surgery: Increased vascularity in the thyroid gland can complicate surgery, so medications are used to decrease vascularity, not increase it.

D. Medications will be administered in the 2 weeks before surgery to reduce the vascularity of the gland: Iodine and other medications are often used to reduce the vascularity and size of the thyroid gland before surgery, which helps minimize the risk of excessive bleeding during the procedure.
