Diabetes Test 2

Question 1

Which diabetes-related claim is untrue?

Accepted Answer

The U.S. prevalence of diabetes is decreasing

Answer

The U.S. prevalence of diabetes has been steadily increasing over the past several decades, not decreasing. This rise is largely attributed to factors such as increasing rates of obesity, an aging population, and improved diagnostic methods. The other statements accurately reflect the significant public health burden and complications associated with diabetes.

Question 2

Treatment for proliferative retinopathy frequently involves:

Accepted Answer

Laser surgery

Answer

Proliferative retinopathy is an advanced stage of diabetic eye disease where new, fragile blood vessels grow on the retina. Laser surgery, specifically panretinal photocoagulation, is a common and effective treatment to destroy these abnormal vessels, preventing further bleeding, scarring, and retinal detachment, thereby preserving vision. Other options are diagnostic tools or treatments for different conditions.

Question 3

All of the following may result in hyperinsulinemia, with the exception of:

Accepted Answer

Type 1 diabetes

Answer

Hyperinsulinemia refers to abnormally high levels of insulin in the blood. In Type 1 diabetes, the body's immune system destroys the insulin-producing beta cells in the pancreas, leading to an absolute deficiency of insulin, not an excess. Conditions like nesidioblastosis (excessive beta cell activity), insulinoma (insulin-secreting tumor), and insulin resistance (where the body produces more insulin to compensate for poor cell response) all result in elevated insulin levels.

Question 4

For a male born in 2000, the risk of developing diabetes is:

Accepted Answer

1 in 3

Answer

According to data from the Centers for Disease Control and Prevention (CDC) and various epidemiological studies, the lifetime risk of developing diabetes for a male born in 2000 is estimated to be approximately 1 in 3. This statistic underscores the significant and growing public health challenge posed by diabetes. The risk is even higher for certain ethnic groups.

Question 5

Which of the following diabetes medications works by reducing the amount of glucose the liver produces?

Accepted Answer

Biguanides

Answer

Biguanides, with metformin being the primary drug in this class, work by reducing the amount of glucose produced by the liver through a process called gluconeogenesis. They also improve insulin sensitivity in peripheral tissues, helping the body use insulin more effectively. Other medication classes listed have different primary mechanisms of action, such as stimulating insulin secretion or delaying carbohydrate absorption.
