1. What is the magnification of an ocular lens on a microscope?

• A. 4x
• B. 10x
• C. 40x
• D. 100x

Correct answer: B

Rationale: The magnification of an ocular lens on a microscope is typically 10x, which is considered standard for most microscopes. Ocular lenses are designed to magnify the image produced by the objective lens further. Choices A, C, and D are incorrect because they do not represent the standard magnification of an ocular lens. A magnification of 4x, 40x, or 100x would not be typical for an ocular lens in a microscope.

2. During a wellness workshop, a healthcare provider is collecting comprehensive health histories from attendees. One of the written questions on the history form states, 'You don't smoke, drink, or take drugs, do you?' This question is an example of:

• A. talking too much.
• B. using confrontation.
• C. using biased or leading questions.
• D. using blunt language to address sensitive topics.

Correct answer: C

Rationale: The question provided is an example of using biased or leading questions. It suggests that one answer is more socially acceptable or preferable than another, potentially pressuring the individual to respond in a specific way. This can result in inaccurate information being provided and may also evoke feelings of guilt or judgment, influencing the person's responses. Choices A, B, and D are incorrect as they do not accurately describe the nature of the question. The question does not involve talking too much, confrontation, or blunt language; instead, it leads the respondent towards a specific answer.

3. Which statement could be inferred from the passage?

• A. The Georgia lab had conducted a previous study on the connection between exercise and energy.
• B. Exercise regimes are not recommended for patients with serious health problems.
• C. An increase in energy levels does not always correspond directly to a reduction in fatigue.
• D. There were fewer than 10 participants in each group in the Georgia study.

Correct answer: A

Rationale: The correct answer is A. The passage mentions a previous study by the same team on the connection between exercise and energy, indicating that the lab had conducted such research before. Choice B is incorrect because the passage actually states that low-impact exercise can help reduce fatigue in patients with serious health conditions. Choice C is incorrect as the passage indicates that an increase in energy levels does correspond to a reduction in fatigue. Choice D is incorrect as the passage does not provide information on the exact number of participants in each group.

4. What role does the liver play in metabolism?

• A. To produce bile
• B. To detoxify harmful substances
• C. To store glucose
• D. To produce insulin

Correct answer: B

Rationale: The correct answer is B: 'To detoxify harmful substances.' The liver is primarily responsible for detoxifying harmful substances present in the blood as part of its role in metabolism. While the liver does produce bile to aid in digestion and stores glucose for energy regulation, its main function in metabolism is detoxification. The liver does not produce insulin; insulin is produced by the pancreas to regulate blood sugar levels.

5. A group of 8 friends went out to eat at a restaurant. They decided to split the bill evenly. If the bill totaled $120, how much did each friend pay?

• A. $15
• B. $10
• C. $12
• D. $20

Correct answer: A

Rationale: To determine how much each friend paid, divide the total bill amount by the number of friends. In this scenario, $120 ÷ 8 friends = $15. Therefore, each friend paid $15. Choice B ($10) is incorrect because dividing $120 by 8 does not yield $10. Choice C ($12) is incorrect because dividing $120 by 8 does not yield $12. Choice D ($20) is incorrect because dividing $120 by 8 does not yield $20.
