1. What is the official name of the metric system?

• A. International Measurement System
• B. International System of Units
• C. Metric Unit System
• D. Measurement System of Units

Correct answer: B

Rationale: The official name of the metric system is the International System of Units (SI). The International System of Units is a globally recognized standard for measurement. Choice A, 'International Measurement System,' is incorrect as it does not accurately reflect the official name. Choice C, 'Metric Unit System,' while related to the metric system, is not the precise official name. Choice D, 'Measurement System of Units,' is a mix-up of terms and does not represent the correct official name of the metric system.

2. What is 0.875 as a simplified fraction?

• A. 7/8
• B. 9/10
• C. 5/6
• D. 3/4

Correct answer: A

Rationale: To convert 0.875 to a fraction, we write it as 875/1000. Then, simplify the fraction by dividing both the numerator and denominator by 125 to get 7/8, which is the simplest form of the fraction. Choice B (9/10), Choice C (5/6), and Choice D (3/4) are all incorrect because they do not represent the value of 0.875 when expressed as a fraction.

3. What is the equivalent of 0.3 mg in mcg?

• A. 300 mcg
• B. 30 mcg
• C. 3000 mcg
• D. 3 mcg

Correct answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you need to multiply by 1000 since 1 mg is equal to 1000 mcg. Therefore, 0.3 mg x 1000 = 300 mcg. This conversion is crucial in healthcare to ensure accurate medication dosages. Choice B (30 mcg) is incorrect as it represents the conversion of 0.03 mg to mcg. Choice C (3000 mcg) is incorrect as it is the result of multiplying 0.3 mg by 10 instead of 1000. Choice D (3 mcg) is incorrect as it is the result of not multiplying by 1000 to convert milligrams to micrograms.

4. How many ounces are in one pint?

• A. 12 ounces
• B. 16 ounces
• C. 8 ounces
• D. 20 ounces

Correct answer: B

Rationale: The correct answer is B: 16 ounces. One pint is equivalent to 16 ounces. This is a common conversion in cooking and baking measurements. Choice A (12 ounces) is incorrect because it does not represent the correct conversion of pints to ounces. Choice C (8 ounces) is incorrect as it is not the correct equivalent for a pint. Choice D (20 ounces) is incorrect as it overestimates the number of ounces in a pint. Understanding these conversions is essential when following recipes or working with liquid measurements in various contexts.

5. How many mcg are there in 0.2 mg?

• A. 20 mcg
• B. 200 mcg
• C. 2000 mcg
• D. 2 mcg

Correct answer: B

Rationale: To convert milligrams to micrograms, you need to multiply by 1000 since 1 mg is equal to 1000 mcg. Therefore, 0.2 mg is equivalent to 200 mcg. It is crucial to understand this conversion to ensure precise medication dosages. Choice A is incorrect because it does not account for the conversion factor of 1000 between milligrams and micrograms. Choice C is incorrect as it represents the conversion of grams to micrograms. Choice D is incorrect as it does not consider the conversion factor from milligrams to micrograms.
