Which of the following pathophysiological mechanisms contributes to hyperglycemia in type 2 diabetes mellitus?

Autoimmune destruction of pancreatic beta cells.

Increased sensitivity of cells to insulin.

Insulin resistance in target tissues.

Excess insulin production by the pancreas.

Answer and Explanation

The Correct Answer is C

In type 2 diabetes, insulin resistance occurs, meaning that the body's cells do not respond effectively to the action of insulin. This leads to decreased glucose uptake by cells and elevated blood sugar levels.

Incorrect choices:

a. This choice is incorrect. Autoimmune destruction of pancreatic beta cells is characteristic of type 1 diabetes, not type 2.

b. This choice is incorrect. Increased sensitivity of cells to insulin would result in improved glucose uptake and reduced hyperglycemia.

d. This choice is incorrect. Excess insulin production by the pancreas is not a typical mechanism in type 2 diabetes.

Correct Answer is B

Explanation

Soaking feet in hot water can lead to burns and is not recommended for individuals with diabetes, as they may have reduced sensation. Warm water and gentle cleaning are more appropriate for foot care.

c. This statement is correct. Wearing comfortable shoes and avoiding high heels helps protect the feet and prevent injuries.

d. This statement is correct. Moisturizing the feet regularly can help prevent dry skin, which can lead to cracks and potential infections.

Correct Answer is D

Explanation

Gestational diabetes mellitus (GDM) is a type of diabetes that develops during pregnancy and is characterized by high blood glucose levels. It usually resolves after childbirth but increases the risk of developing type 2 diabetes in the future.

Incorrect choices:

a. This choice is incorrect. GDM typically resolves after childbirth, not after.

b. This choice is incorrect. GDM is not a rare condition; it affects a significant percentage of pregnant women.

c. This choice is incorrect. Women with GDM have an increased risk of developing type 2 diabetes, not type 1 diabetes, later in life.
