1. 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.

2. How many quarts are in 1 gallon?

• A. 2 quarts
• B. 4 quarts
• C. 3 quarts
• D. 1 quart

Correct answer: B

Rationale: The correct answer is B: 4 quarts. There are 4 quarts in 1 gallon. This conversion is based on the fact that 1 gallon is equivalent to 4 quarts. Choice A is incorrect as 2 quarts are half of a gallon, not a whole gallon. Choice C is incorrect as 3 quarts is less than a gallon. Choice D is incorrect as it represents only one quart, whereas the question asks for the quantity in a gallon.

3. Convert 0.20 liters to milliliters. What is the equivalent volume?

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

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in 1 liter. So, 0.20 liters x 1000 = 200 milliliters. This makes choice A, '200 ml,' the correct answer. Choices B, C, and D are incorrect because they do not reflect the correct conversion factor from liters to milliliters.

4. What is 0.04 g in mg?

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

Correct answer: A

Rationale: To convert grams to milligrams, you multiply by 1000 since there are 1000 milligrams in a gram. Therefore, to convert 0.04 grams to milligrams, you would do 0.04 * 1000 = 40 mg. Choice A, '40 mg,' is the correct answer. Choices B, C, and D are incorrect because they do not correctly convert grams to milligrams. Choice B, '400 mg,' is incorrect because it mistakenly multiplies by 10 instead of 1000. Choice C, '4 mg,' is incorrect because it does not account for the correct conversion factor. Choice D, '0.4 mg,' is incorrect because it underestimates the conversion by a factor of 10.

5. How many milliliters are in 2 liters?

• A. 20 mL
• B. 200 mL
• C. 2,000 mL
• D. 20,000 mL

Correct answer: C

Rationale: To convert liters to milliliters, you need to multiply the number of liters by 1,000 since there are 1,000 milliliters in 1 liter. Therefore, 2 liters x 1,000 = 2,000 milliliters. Choices A, B, and D are incorrect because they do not account for the correct conversion factor from liters to milliliters.
