The nurse is explaining the role of insulin in diabetes mellitus. Which statement by the client indicates a need for further clarification?

"Insulin helps regulate blood sugar by allowing glucose to enter cells for energy."

"Insulin is produced by the pancreas and released in response to high blood sugar levels."

"In type 1 diabetes, the body does not produce insulin, so it must be administered externally."

"In type 2 diabetes, the body's cells become resistant to the effects of insulin."

Answer and Explanation

The Correct Answer is C

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.

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.

Incorrect choices:

a. This statement is correct. Daily inspection of the feet is important to detect any cuts, sores, or blisters early and prevent complications.

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.

A. Liver. B. Kidneys. C. Lungs. D. Spleen.

Correct Answer is A

Explanation

The liver plays a central role in blood glucose regulation by releasing glucose into the bloodstream through glycogenolysis and gluconeogenesis when blood glucose levels are low. It also stores glucose as glycogen and responds to insulin and glucagon signals.

Incorrect choices:

b. This choice is incorrect. While the kidneys play a role in filtering blood and excreting waste products, they are not primarily responsible for regulating blood glucose levels.

c. This choice is incorrect. The lungs are involved in oxygen and carbon dioxide exchange and are not directly involved in blood glucose regulation.

d. This choice is incorrect. The spleen is involved in immune function and blood filtration, but it does not play a central role in blood glucose regulation.
