Which of the following is not true of type 1 diabetes?
Can be treated with oral glycemic agents.
Definite genetic link.
Pancreas is completely unable to produce insulin.
Acute onset.
The Correct Answer is A
Choice A reason: Type 1 diabetes cannot be treated with oral glycemic agents. These medications are typically used to manage type 2 diabetes, which is characterized by insulin resistance rather than a lack of insulin production. In type 1 diabetes, the pancreas is unable to produce insulin due to an autoimmune destruction of insulin-producing beta cells. Therefore, individuals with type 1 diabetes require insulin therapy to manage their blood glucose levels effectively.
Choice B reason: Type 1 diabetes has a definite genetic component, though it is not solely determined by genetics. A combination of genetic predisposition and environmental factors, such as viral infections or other autoimmune triggers, can lead to the development of type 1 diabetes. Certain genes, including those in the HLA region, are known to increase susceptibility to the disease.
Choice C reason: In type 1 diabetes, the pancreas is indeed completely unable to produce insulin. This is due to an autoimmune attack on the beta cells of the pancreas, which are responsible for insulin production. Without insulin, the body cannot regulate blood glucose levels, leading to hyperglycemia and the need for exogenous insulin administration.
Choice D reason: Type 1 diabetes often has an acute onset, particularly in children and young adults. Symptoms can develop rapidly over a few days to weeks, including increased thirst, frequent urination, unintended weight loss, and severe fatigue. This acute presentation is a hallmark of the disease and contrasts with the more gradual onset seen in type 2 diabetes.

Correct Answer is B
Explanation
Choice A reason: Edema refers to the accumulation of fluid in the interstitial spaces of tissues, leading to swelling. While it involves fluid retention, it does not specifically describe fluid accumulation in the peritoneal cavity.
Choice B reason: Third spacing refers to the abnormal accumulation of fluid in areas where it is not normally found, such as the peritoneal cavity, pleural cavity, or pericardial sac. In the context of the peritoneal cavity, this condition is known as ascites, a type of third spacing.
Choice C reason: Blanching refers to the whitening of the skin when pressure is applied, which is often used as a sign to assess capillary refill time. It does not relate to fluid accumulation.
Choice D reason: Pitting edema refers to a type of edema where pressing on the swollen area leaves an indentation or "pit" that takes time to refill. While it is a type of fluid retention, it does not specifically describe fluid accumulation in the peritoneal cavity.
Correct Answer is D
Explanation
Choice A reason: Exercise has been shown to decrease the cardiovascular effects of excessive glucose. Regular physical activity helps improve cardiovascular health by reducing blood pressure, improving cholesterol levels, and enhancing blood flow. In individuals with type 2 diabetes, exercise can help lower blood glucose levels and reduce the risk of cardiovascular complications, which are common in diabetes due to chronic high blood glucose levels.
Choice B reason: Skeletal muscles can indeed use glucose without a proportionate insulin amount during exercise. This is because exercise increases insulin sensitivity and allows muscles to take up glucose more efficiently. As a result, physical activity can help lower blood glucose levels and improve overall glucose control in individuals with type 2 diabetes.
Choice C reason: Exercise decreases stress, which is beneficial for individuals with type 2 diabetes. Physical activity helps release endorphins, which are natural stress relievers. Lower stress levels can help improve blood glucose control, as stress hormones like cortisol can raise blood glucose levels. Therefore, reducing stress through exercise can contribute to better diabetes management.
Choice D reason: All of the above reasons are correct. Exercise is encouraged in type 2 diabetes because it provides multiple benefits, including improving cardiovascular health, enhancing glucose uptake by skeletal muscles, and reducing stress levels. These combined effects help improve overall blood glucose control and reduce the risk of complications associated with type 2 diabetes.
