Which of the following statements accurately describes the pathophysiology of type 1 diabetes mellitus?

In type 1 diabetes, the body's cells become resistant to the effects of insulin.

Type 1 diabetes is primarily caused by lifestyle factors such as obesity and sedentary behavior.

In type 1 diabetes, the pancreas produces insufficient amounts of insulin or no insulin at all.

Type 1 diabetes typically develops in adulthood and is often associated with insulin resistance.

Answer and Explanation

The Correct Answer is C

Type 1 diabetes is characterized by the autoimmune destruction of pancreatic beta cells, leading to a lack of insulin production. This results in an absolute insulin deficiency and requires external insulin administration.

Incorrect choices:

a. This choice is incorrect. Insulin resistance is a characteristic of type 2 diabetes, not type 1.

b. This choice is incorrect. Type 1 diabetes is not primarily caused by lifestyle factors; it has an autoimmune etiology.

d. This choice is incorrect. Type 1 diabetes typically develops in childhood or adolescence, not adulthood, and is not associated with insulin resistance.

Correct Answer is C

Explanation

This statement is incorrect because it inaccurately suggests that insulin administration is only necessary for type 1 diabetes. While it is essential for type 1 diabetes, it can also be used in some cases of type 2 diabetes when other treatments are ineffective.

Incorrect choices:

a. This statement is correct. Insulin facilitates the entry of glucose into cells for energy.

b. This statement is correct. Insulin is produced by the pancreas and released in response to elevated blood sugar levels.

d. This statement is correct. In type 2 diabetes, insulin resistance occurs, meaning the body's cells become less responsive to the effects of insulin.

A. Type 1 diabetes mellitus. B. Type 2 diabetes mellitus. C. Gestational diabetes mellitus. D. Secondary diabetes mellitus.

Correct Answer is C

Explanation

Gestational diabetes mellitus (GDM) occurs during pregnancy due to hormonal changes that increase insulin resistance. It usually resolves after childbirth, but women with GDM have an increased risk of developing type 2 diabetes later in life.

Incorrect choices:

a. This choice is incorrect. Type 1 diabetes mellitus involves autoimmune destruction of beta cells and is not related to pregnancy.

b. This choice is incorrect. Type 2 diabetes mellitus involves insulin resistance and relative insulin deficiency and is not specific to pregnancy.

d. This choice is incorrect. Secondary diabetes mellitus is caused by other underlying medical conditions or factors and is not specific to pregnancy.
