c)

Dry skin, rapid heartbeat, and weight loss.

d)

Coughing, sneezing, and sore throat.

2.

What is the function of red blood cells (RBCs)?

a)

To transport oxygen from the lungs to the body's tissues and carry carbon dioxide back to the lungs for exhalation.

b)

To produce hormones that regulate metabolism.

c)

To fight infections and provide immunity to the body.

d)

To aid in the digestion of food and absorption of nutrients.

3.

What is Type 2 Diabetes?

a)

A chronic condition that affects the way the body processes blood sugar (glucose).

b)

A temporary condition that occurs during pregnancy.

c)

A genetic disorder that affects the production of insulin.

d)

An autoimmune disease that destroys insulin-producing cells.

4.

What is negative feedback in the body?

a)

A process where the output of a system reduces or dampens the original stimulus, helping to maintain homeostasis.

b)

A mechanism that amplifies the original stimulus to enhance a response.

c)

A process that has no effect on the body's systems.

d)

A method of communication between cells that increases activity.

5.

What are the main differences between Type 1 and Type 2 Diabetes?

a)

Type 1 diabetes is an autoimmune condition where the body does not produce insulin, while Type 2 diabetes is characterized by insulin resistance and often associated with obesity.

b)

Type 1 diabetes is caused by excessive sugar intake, while Type 2 diabetes is primarily genetic.

c)

Type 1 diabetes can be cured with medication, while Type 2 diabetes requires insulin injections for life.

d)

Type 1 diabetes occurs only in children, while Type 2 diabetes occurs only in adults.

6.

What is the importance of insulin in the body?

a)

Insulin is a hormone that regulates blood sugar levels by facilitating the uptake of glucose into cells for energy.

b)

Insulin is a vitamin that helps in the absorption of nutrients from food.

c)

Insulin is a protein that builds muscle mass in the body.

d)

Insulin is a mineral that strengthens bones and teeth.

7.

What is pre-diabetes?

a)

A condition where blood sugar levels are normal.

b)

A condition where blood sugar levels are higher than normal but not high enough to be classified as Type 2 diabetes.

c)

A condition that only affects overweight individuals.

d)

A condition that can be cured with immediate lifestyle changes.

8.

What lifestyle changes can help manage Type 2 Diabetes?

a)

Regular physical activity, a balanced diet, weight management, and monitoring blood sugar levels

b)

Increased sugar intake and reduced physical activity

c)

Eating only low-carb foods and avoiding all fruits

d)

Drinking excessive amounts of soda and skipping meals

9.

How does obesity relate to Type 2 Diabetes?

a)

Obesity has no effect on Type 2 Diabetes.

b)

Obesity decreases the risk of developing Type 2 Diabetes.

c)

Obesity increases the risk of developing Type 2 Diabetes due to its association with insulin resistance.

d)

Obesity only affects Type 1 Diabetes.

10.

What are the potential complications of untreated diabetes?

a)

Cardiovascular disease

b)

Nerve damage

c)

Kidney damage

d)

a)

Below 80%

b)

Below 85%

c)

Below 90%

d)

Below 95%

12.

a)

90% to 95%

b)

92% to 98%

c)

95% to 100%

d)

97% to 100%

13.

What is insulin resistance?

a)

A condition where the body produces too much insulin.

b)

A condition in which the body's cells become less responsive to insulin, often leading to Type 2 diabetes.

c)

A condition that only affects people with Type 1 diabetes.

d)

A temporary state that resolves with diet changes.

14.

What is the role of Hemoglobin in the blood?

a)

To carry oxygen from the lungs to the rest of the body and return carbon dioxide back to the lungs.

b)

To help in blood clotting and prevent excessive bleeding.

c)

To transport nutrients from the digestive system to the cells.

d)

To regulate body temperature and maintain homeostasis.

15.

What is the significance of monitoring blood sugar levels?

a)

It helps in managing diabetes and preventing complications such as heart disease, nerve damage, and kidney failure.

b)

It is only necessary for patients with severe diabetes.

c)

It has no impact on overall health.
