1. How does being overweight predispose a person to a particular condition?

• A. Cancer
• B. Diabetes
• C. Heart disease
• D. Obesity

Correct answer: B

Rationale: Being overweight increases the risk of developing conditions like diabetes. Excessive weight can lead to insulin resistance and metabolic dysfunction, which are key factors in the development of type 2 diabetes. While obesity is a result of being overweight, it is not a condition that being overweight predisposes a person to. Cancer and heart disease can also be influenced by weight but are not the primary conditions typically associated with being overweight.

2. What is 60% of 150?

• A. 80
• B. 90
• C. 120
• D. 80

Correct answer: B

Rationale: To find 60% of 150, you multiply 0.6 by 150, which equals 90. Therefore, the correct answer is 90. Choice A (80) is incorrect because it does not represent 60% of 150. Choice C (120) is incorrect as it exceeds 100% of 150. Choice D (80) is a duplicate of choice A and does not accurately represent 60% of 150.

3. Which hormone is released by the pancreas to lower blood glucose levels?

• A. Insulin
• B. Glucagon
• C. Cortisol
• D. Somatostatin

Correct answer: A

Rationale: Insulin is the hormone released by the pancreas to lower blood glucose levels. Insulin facilitates the uptake of glucose into cells, helping to decrease blood glucose levels and store excess glucose for energy or future use. Glucagon, on the other hand, raises blood glucose levels by promoting the breakdown of glycogen into glucose. Cortisol and somatostatin do not directly regulate blood glucose levels in the same manner as insulin and glucagon.

4. A truculent patient is ______

• A. Friendly
• B. Argumentative
• C. Cooperative
• D. Passive

Correct answer: B

Rationale: A truculent patient is characterized by being argumentative or hostile. This type of patient tends to be confrontational and uncooperative, often displaying aggressive behavior. Choice A, 'Friendly,' is incorrect as truculent patients are not known for their friendliness. Choice C, 'Cooperative,' is also incorrect as truculent patients are the opposite of cooperative. Choice D, 'Passive,' is incorrect because truculent patients are not passive but rather assertive and combative.

5. A lab needs 200ml of a 5% salt solution. They only have a 10% solution. How much 10% solution and water should be mixed?

• A. 100ml 10% solution, 100ml water
• B. 150ml 10% solution, 50ml water
• C. 160ml 10% solution, 40ml water
• D. 200ml 10% solution, 0ml water

Correct answer: B

Rationale: Rationale: 1. Let x be the volume of the 10% solution needed and y be the volume of water needed. 2. The total volume of the final solution is 200ml, so x + y = 200. 3. The concentration of the final solution is 5%, so the amount of salt in the final solution is 0.05 * 200 = 10g. 4. The amount of salt in the 10% solution is 0.1x, and the amount of salt in the water is 0, so the total amount of salt in the final solution is 0.1x. 5. Since the total amount of salt in the final solution is 10g, we have 0.1x = 10. 6. Solving for x, we get x = 100ml. 7. Substituting x =
