Nursing Elites

1. The _____ student was not well liked by his peers.

• A. Geniality
• B. Affably
• C. Gregarious
• D. Detestable

Correct answer: D

Rationale: The correct answer is 'Detestable.' In this context, 'detestable' means deserving intense dislike, which fits the sentence describing a student who is not well-liked. 'Geniality' (choice A) means warmth and friendliness, which is the opposite of what is described in the sentence. 'Affably' (choice B) means in a friendly and pleasant manner, which doesn't convey the idea of being disliked. 'Gregarious' (choice C) means sociable and outgoing, which is also not suitable for describing someone who is not well-liked.

2. What is 20% of 150?

• A. 25
• B. 30
• C. 35
• D. 20

Correct answer: B

Rationale: To find 20% of 150, you need to multiply 150 by 0.20: 150 × 0.20 = 30. Therefore, 20% of 150 is indeed 30. Choice A (25) is incorrect as it represents 20% of 125, not 150. Choice C (35) is incorrect as it represents more than 20% of 150. Choice D (20) is incorrect as it is the original percentage to find.

3. Which mineral supports the function of the thyroid?

• A. Manganese
• B. Iodine
• C. Phosphorus
• D. Zinc

Correct answer: B

Rationale: Iodine is the mineral that supports the function of the thyroid. The thyroid gland requires iodine to produce thyroid hormones, which are essential for regulating metabolism and other important bodily functions. A deficiency in iodine can lead to thyroid disorders such as hypothyroidism or goiter. Manganese (Choice A), Phosphorus (Choice C), and Zinc (Choice D) do not play a direct role in supporting the thyroid function like iodine does. While these minerals are important for various bodily functions, they are not specifically required for the thyroid gland's hormone production.

4. How many neutrons are in an atom of carbon-12?

• A. 2
• B. 4
• C. 6
• D. 24

Correct answer: C

Rationale: An atom of carbon-12 has 6 neutrons. The atomic number of carbon is 6, representing the number of protons. The atomic mass of carbon-12 is 12. To find the number of neutrons, subtract the atomic number from the atomic mass: 12 - 6 = 6 neutrons. Choice A, 2, is incorrect as it does not reflect the correct calculation for neutrons in carbon-12. Choice B, 4, is incorrect as it does not match the correct number of neutrons in carbon-12. Choice D, 24, is incorrect as it is significantly higher than the actual number of neutrons in carbon-12.

5. Muscles are connected to bones by ______, and bones are connected to each other by ______.

• A. Muscles
• B. Tendons, ligaments
• C. Muscles
• D. Ligaments

Correct answer: B

Rationale: Muscles are connected to bones by tendons, which allow the muscle to exert force on the bone for movement. Bones are connected to each other by ligaments, which provide stability and support to the joints between bones. This relationship between muscles, tendons, bones, and ligaments is essential for proper movement and function of the musculoskeletal system. Choice A is incorrect because muscles are not directly connected to bones; tendons serve as the connection between muscles and bones. Choice D is incorrect because ligaments connect bones to each other, not muscles to bones.
