1. What is the function of parathyroid hormone?

• A. Increasing energy levels
• B. Stimulating cell reproduction
• C. Speeding up metabolism
• D. Activating vitamin D

Correct answer: D

Rationale: The correct answer is D. Parathyroid hormone plays a crucial role in activating vitamin D. This activation occurs in the kidneys, where parathyroid hormone stimulates the conversion of inactive vitamin D to its active form. Active vitamin D is essential for maintaining proper levels of calcium and phosphorus in the body, which are important for bone health and other physiological functions. Choices A, B, and C are incorrect because parathyroid hormone is not involved in increasing energy levels, stimulating cell reproduction, or speeding up metabolism. Its primary function is related to calcium and phosphorus homeostasis through the activation of vitamin D.

2. What is the result of dividing 3.44 by 0.6?

• A. 11.41
• B. 5.73
• C. 2.33
• D. 0.57

Correct answer: B

Rationale: The correct answer is B: 5.73. When dividing 3.44 by 0.6, the calculation is 3.44 ÷ 0.6 = 5.73. Choice A (11.41) is incorrect because it is the result of multiplying, not dividing. Choice C (2.33) and Choice D (0.57) are also incorrect results obtained by incorrect calculations.

3. What is the author’s primary purpose in writing the essay about Sunny-Side Up?

• A. To persuade.
• B. To reflect.
• C. To entertain.
• D. To inform.

Correct answer: D

Rationale: The author's primary purpose is to inform readers about the benefits of sunlight, including its role in vitamin D synthesis and other health benefits. While the passage does advocate for sunlight exposure, the primary aim is to provide information rather than persuade or entertain, making D the most accurate choice.

4. A patient is prescribed 500 mg of medication, but the available tablets are 250 mg each. How many tablets should be given?

• A. 3 tablets
• B. 2 tablets
• C. 4 tablets
• D. 5 tablets

Correct answer: B

Rationale: To find out how many tablets of 250 mg are needed to reach a total of 500 mg, you divide the total prescribed dosage by the dosage per tablet. In this case, 500 mg / 250 mg per tablet = 2 tablets. Therefore, the correct answer is 2 tablets. Choice A (3 tablets) is incorrect because it would exceed the prescribed dosage. Choices C (4 tablets) and D (5 tablets) are incorrect as they would also provide more medication than needed.

5. Select the meaning of the underlined word in the following sentence. The chemicals in plastic containers may be deleterious to children’s health.

• A. Harmful
• B. Deleting
• C. Delightful
• D. Inoffensive

Correct answer: A

Rationale: The word 'deleterious' means causing harm or damage. In this context, the sentence implies that the chemicals in plastic containers can be harmful to children's health. Therefore, the correct meaning of the underlined word is 'harmful,' making option A the most suitable choice. Option B 'Deleting' is incorrect because it refers to removing or erasing, which does not fit the context. Option C 'Delightful' is incorrect as it means causing great pleasure or delight, the opposite of the intended meaning. Option D 'Inoffensive' is incorrect as it means not causing any harm or annoyance, which is contrary to the negative impact described in the sentence.
