Question 1

Which of the following is a common symptom of hyperthyroidism?

Accepted Answer

Heat intolerance

Answer

Hyperthyroidism is characterized by an overproduction of thyroid hormones, which significantly increases the body's metabolic rate. This elevated metabolism generates excess heat, causing individuals to feel uncomfortably warm and experience heat intolerance. Other common symptoms include weight loss, rapid heart rate, and nervousness.

Question 2

What is the most common cause of primary hypothyroidism?

Accepted Answer

Autoimmune thyroiditis (Hashimoto's disease)

Answer

Autoimmune thyroiditis, commonly known as Hashimoto's disease, is the most prevalent cause of primary hypothyroidism. In this condition, the body's immune system mistakenly attacks and gradually destroys the thyroid gland's cells. This chronic autoimmune assault impairs the thyroid's ability to produce sufficient thyroid hormones, leading to an underactive thyroid state.

Question 3

Which of the following laboratory tests is the best indicator of long-term glycemic control in diabetic patients?

Accepted Answer

Hemoglobin A1c

Answer

Hemoglobin A1c (HbA1c) is the best indicator of long-term glycemic control because it measures the average blood glucose levels over the preceding 2 to 3 months. This test reflects the amount of glucose attached to hemoglobin in red blood cells, which have a lifespan of approximately 120 days. Unlike fasting or random blood glucose tests, HbA1c provides a comprehensive picture of glucose management, making it crucial for monitoring diabetes treatment effectiveness.

Question 4

Which hormone is responsible for lowering blood glucose levels?

Accepted Answer

Insulin

Answer

Insulin is a hormone produced by the beta cells of the pancreas, and its primary role is to lower blood glucose levels. After a meal, when blood glucose rises, insulin is released to facilitate the uptake of glucose from the bloodstream into cells for energy or storage. It acts as a key, allowing glucose to enter cells, thereby reducing its concentration in the blood.

Question 5

In patients with Addison's disease, which hormone is deficient?

Accepted Answer

Cortisol

Answer

Addison's disease is a rare but serious condition characterized by the adrenal glands' inability to produce sufficient amounts of certain hormones. The most significant deficiency in Addison's disease is cortisol, a glucocorticoid vital for stress response, metabolism, and immune function. Aldosterone, a mineralocorticoid, may also be deficient, leading to electrolyte imbalances.
