1. How many micrograms are in 1 milligram?

• A. 1 µg
• B. 10 µg
• C. 100 µg
• D. 1,000 µg

Correct answer: D

Rationale: The correct answer is D: 1,000 µg. To convert milligrams to micrograms, you need to multiply by 1,000 because there are 1,000 micrograms in 1 milligram. Choices A, B, and C are incorrect because they do not correctly convert milligrams to micrograms. 1 milligram is equal to 1,000 micrograms, making choice D the right answer.

2. How many milligrams are in 2 grams?

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

Correct answer: B

Rationale: To convert grams to milligrams, you need to multiply by 1,000 since there are 1,000 milligrams in a gram. Therefore, 2 grams is equal to 2,000 milligrams. Choice A (200 mg) is incorrect as it represents 0.2 grams. Choice C (20 mg) is incorrect as it represents 0.02 grams. Choice D (20,000 mg) is incorrect as it represents 20 grams.

3. Convert 0.2 liters to milliliters. What is the equivalent volume?

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

Correct answer: B

Rationale: To convert 0.2 liters to milliliters, you need to multiply by 1,000 because there are 1,000 milliliters in a liter. So, 0.2 * 1,000 = 200 milliliters. Therefore, the correct answer is 200 ml. Choice A (20 ml) is incorrect because it represents 0.02 liters, not 0.2 liters. Choice C (2 ml) is incorrect as it represents 0.002 liters. Choice D (2000 ml) is incorrect as it represents 2 liters, not 0.2 liters.

4. Convert 0.04 grams to milligrams.

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

Correct answer: A

Rationale: To convert 0.04 grams to milligrams, you need to multiply by 1000, not 10000. Therefore, 0.04 grams equals 40 milligrams (0.04g * 1000 = 40mg). Choice B, '4 mg,' is incorrect as it reflects the value as if it was in grams. Choice C, '400 mg,' is incorrect as it incorrectly multiplies by 100 instead of 1000. Choice D, '0.4 mg,' is incorrect as it incorrectly moves the decimal point to the right instead of multiplying by 1000.

5. How many liters are in 2,000 milliliters?

• A. 0.2 liters
• B. 2 liters
• C. 0.02 liters
• D. 20 liters

Correct answer: B

Rationale: The correct answer is B: 2 liters. To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in a liter. Therefore, 2,000 milliliters is equal to 2 liters (2000 ÷ 1000 = 2). Choices A, C, and D are incorrect because they incorrectly convert milliliters to liters, resulting in values that are too low (A and C) or too high (D).
