1. Which vitamin is essential for the synthesis of collagen?

• A. Vitamin C
• B. Vitamin D
• C. Vitamin B12
• D. Vitamin K

Correct answer: A

Rationale: The correct answer is Vitamin C. Vitamin C is essential for the synthesis of collagen, a protein crucial for maintaining the structure and integrity of skin, blood vessels, and bones. It plays a key role in the hydroxylation of proline and lysine residues in collagen synthesis, which is necessary for the stability and strength of collagen fibers. Choice B: Vitamin D is essential for bone health and calcium absorption but is not directly involved in collagen synthesis. Choice C: Vitamin B12 is important for red blood cell formation and neurological function but is not directly related to collagen synthesis. Choice D: Vitamin K is necessary for blood clotting and bone metabolism but does not play a direct role in collagen synthesis.

2. What is 28% of 100?

• A. 28
• B. 20
• C. 25
• D. 30

Correct answer: A

Rationale: The correct answer is A: 28. To find 28% of 100, you multiply 0.28 (the decimal equivalent of 28%) by 100. This calculation results in 28. Therefore, 28% of 100 is 28. Choice B, 20, is incorrect as it represents 20% of 100. Choice C, 25, is incorrect as it represents 25% of 100. Choice D, 30, is incorrect as it represents 30% of 100.

3. To implement something is to:

• A. prevent it from occurring
• B. emphasize the importance of
• C. cause it to happen
• D. follow from beginning to end

Correct answer: C

Rationale: The correct answer is C: 'cause it to happen.' 'Implement' means to put something into action or cause it to happen. Choices A, B, and D are incorrect because they do not reflect the meaning of 'implement.' Preventing something from occurring (Choice A), emphasizing the importance of something (Choice B), and following something from beginning to end (Choice D) are all different actions or concepts that do not align with the definition of 'implement.'

4. What is a device?

• A. An idea or concept
• B. A tool or piece of equipment
• C. A small part of a larger structure
• D. An accessory for fashion

Correct answer: B

Rationale: A device is defined as a tool or piece of equipment designed to serve a specific purpose. It is used to perform a particular function or task. An idea or concept (Choice A) may lead to the creation of a device, but they are not devices themselves. Choice C, referring to a small part of a larger structure, does not encompass the general definition of a device which implies standalone functionality. Choice D, an accessory for fashion, is entirely unrelated to the usual understanding of a device, which focuses on functionality rather than aesthetics.

5. The physician orders 1000 mg of Benadryl liquid; 1 g = 1 tsp. How many teaspoons will you give?

• A. .75 tsp
• B. 1.5 tsp
• C. 1 tsp
• D. 1.25 tsp

Correct answer: C

Rationale: Since 1 gram (g) equals 1000 milligrams (mg) and 1 g = 1 teaspoon (tsp), the prescribed 1000 mg is equal to 1 tsp. Therefore, you will give 1 teaspoon of the Benadryl liquid. Choices A, B, and D are incorrect because they do not correspond to the correct conversion of 1 g to 1 tsp, which is essential in solving this dosage calculation.
