1. What is 0.25 mg to mcg?

• A. 250 mcg
• B. 25 mcg
• C. 2.5 mcg
• D. 2500 mcg

Correct answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you multiply by 1000 because 1 mg is equal to 1000 mcg. Therefore, 0.25 mg is equal to 250 mcg. Choices B, C, and D are incorrect as they do not consider the correct conversion factor.

2. What is equivalent to 1 L?

• A. 1 kilogram
• B. 1 quart
• C. 1 milliliter
• D. 1000 milliliters

Correct answer: D

Rationale: 1 liter is equivalent to 1000 milliliters. This conversion is based on the fact that 1 liter equals 1000 milliliters, a standard metric relationship. Choice A is incorrect because a kilogram is a unit of mass, not volume. Choice B, 1 quart, is a non-metric unit of volume and is not equivalent to 1 liter. Choice C, 1 milliliter, is too small to be equivalent to 1 liter; it takes 1000 milliliters to make up 1 liter.

3. What is 0.04 grams converted to milligrams?

• A. 40 mg
• B. 4 mg
• C. 400 mg
• D. 0.4 mg

Correct answer: A

Rationale: To convert grams to milligrams, you need to multiply by 1000, not 10000. Therefore, to convert 0.04 grams to milligrams, you multiply 0.04 by 1000, which equals 40 mg. Choice A (40 mg) is the correct answer. Choice B (4 mg) is incorrect as it represents converting 0.004 grams to milligrams. Choice C (400 mg) is incorrect as it is 10 times the correct conversion. Choice D (0.4 mg) is incorrect as it is 10 times smaller than the correct conversion.

4. What does 'cm' stand for in the metric system?

• A. centimeter
• B. cubic meter
• C. cord
• D. centi

Correct answer: A

Rationale: In the metric system, 'cm' stands for centimeter, which is a unit of length equal to 1/100th of a meter. The correct answer is 'centimeter' (A). Choice B, 'cubic meter,' is a unit of volume, not length. Choice C, 'cord,' is not a standard metric unit. Choice D, 'centi,' is a prefix meaning one-hundredth, but 'cm' specifically stands for centimeter, not just the prefix.

5. What is 0.075 mg converted to micrograms?

• A. 75 mcg
• B. 7.5 mcg
• C. 0.75 mcg
• D. 750 mcg

Correct answer: D

Rationale: To convert milligrams to micrograms, you need to multiply by 1000 since there are 1000 micrograms in a milligram. Therefore, to convert 0.075 mg to mcg, you would multiply 0.075 by 1000, which equals 75. Thus, the correct conversion is 750 mcg. Choice A, 75 mcg, is incorrect as it's the result if you mistakenly multiply by 10 instead of 1000. Choice B, 7.5 mcg, is incorrect as it's the result if you divide by 10 instead of multiplying by 1000. Choice C, 0.75 mcg, is incorrect as it's the result if you divide by 100 instead of multiplying by 1000.
