1. What are the finger-like projections that increase the surface area for absorption in the small intestine called?

• A. Crypts of Lieberkühn
• B. Goblet cells
• C. Villi
• D. Paneth cells

Correct answer: C

Rationale: A) Crypts of Lieberkühn are small pits in the lining of the small intestine that contain cells involved in the production of intestinal juices, but they do not increase the surface area for absorption. B) Goblet cells are specialized cells that secrete mucus to protect the lining of the digestive tract, but they do not increase the surface area for absorption. C) Villi are finger-like projections in the small intestine that increase the surface area available for nutrient absorption. Each villus contains blood vessels and lacteals (lymphatic vessels) that help absorb nutrients from digested food. D) Paneth cells are specialized cells found in the small intestine that secrete antimicrobial substances, but they do not increase the surface area for absorption.

2. Kimberley earns $10 an hour babysitting, and after 10 p.m., she earns $12 an hour, with the amount paid being rounded to the nearest hour accordingly. On her last job, she worked from 5:30 p.m. to 11 p.m. In total, how much did Kimberley earn on her last job?

• A. $45
• B. $57
• C. $62
• D. $42

Correct answer: C

Rationale: Kimberley worked from 5:30 p.m. to 11 p.m., which is a total of 5.5 hours before 10 p.m. (from 5:30 p.m. to 10 p.m.) and 1 hour after 10 p.m. The earnings she made before 10 p.m. at $10 an hour was 5.5 hours * $10 = $55. Her earnings after 10 p.m. for the rounded hour were 1 hour * $12 = $12. Therefore, her total earnings for the last job were $55 + $12 = $67. Since the amount is rounded to the nearest hour, the closest rounded amount is $62. Therefore, Kimberley earned $62 on her last job. Choice A is incorrect as it does not consider the additional earnings after 10 p.m. Choices B and D are incorrect as they do not factor in the hourly rates and the total hours worked accurately.

3. Based on the facts in the passage, what prediction could you make about the time immediately following the Louisiana Purchase?

• A. Explorers were already on their way to the region.
• B. The government aimed to increase its power.
• C. Government officials would ensure explorers were dispatched to the region.
• D. Explorers would expect compensation for their work.

Correct answer: A

Rationale: The correct answer is A. The passage mentions that explorers like Lewis and Clark were sent to the newly acquired Louisiana Territory immediately after the Louisiana Purchase. This indicates that explorers were already on their way to the region following the purchase. Choice B is incorrect as there is no direct mention of the government wanting to increase its power right after the purchase. Choice C is incorrect as the passage does not state that government officials would specifically ensure explorers were dispatched to the region. Choice D is incorrect because there is no information provided in the passage about explorers expecting payment for their work.

4. Within a nursing program, 25% of the class wanted to work with infants, 60% wanted to work with the elderly, 10% wanted to assist general practitioners, and the rest were undecided. What fraction of the class wanted to work with the elderly?

• A. 1/4
• B. 1/10
• C. 3/5
• D. 1/20

Correct answer: C

Rationale: To find the fraction of the class wanting to work with the elderly, we convert the percentage to a fraction. 60% can be written as 60/100, which simplifies to 3/5. Therefore, 3/5 of the class wanted to work with the elderly. Choice A (1/4), choice B (1/10), and choice D (1/20) do not represent the fraction of the class wanting to work with the elderly, making them incorrect.

5. Which of the following is true about calcium-rich foods? I. Canned salmon with bones contains calcium. II. Cheese is a lactose-free food. III. Condensed soup made with water is a calcium-rich food.

• A. I only
• B. I and II only
• C. II and III only
• D. III only

Correct answer: A

Rationale: The correct answer is 'I only.' Canned salmon with bones contains calcium as the bones are a good source of calcium, making statement I true. However, statement II is false as cheese is not a lactose-free food. Statement III is also incorrect as condensed soup made with water is not necessarily a calcium-rich food. Other calcium-rich options include dairy products like milk, yogurt, and specific non-dairy products like calcium-fortified juices, canned fish with bones, soybeans, and leafy greens.
