1. Convert 0.025 mg to micrograms.

• A. 25 mcg
• B. 250 mcg
• C. 2.5 mcg
• D. 0.25 mcg

Correct answer: A

Rationale: To convert milligrams to micrograms, you multiply by 1000, not 10000. Therefore, 0.025 mg equals 25 mcg. Choice B (250 mcg) is incorrect as it incorrectly multiplies by 10000. Choice C (2.5 mcg) is incorrect as it incorrectly divides by 10. Choice D (0.25 mcg) is incorrect as it incorrectly multiplies by 10.

2. What is the equivalent of 0.3 milliliters?

• A. 0.03 ml
• B. 0.3 ml
• C. 3 ml
• D. 30 ml

Correct answer: B

Rationale: 0.3 milliliters is equivalent to 0.3 ml. This is a precise measurement commonly used in medical settings for administering small doses of liquid medication. It is important to understand and recognize the decimal point placement when converting between milliliters and other volume units. Choice A (0.03 ml) is incorrect as it represents a smaller amount than 0.3 ml. Choice C (3 ml) and Choice D (30 ml) are also incorrect as they are larger measurements and do not match the given amount of 0.3 ml.

3. Convert 5 kilometers to meters.

• A. 50 meters
• B. 500 meters
• C. 5000 meters
• D. 0.5 meters

Correct answer: C

Rationale: To convert kilometers to meters, you need to multiply by 1000 because there are 1000 meters in 1 kilometer. Therefore, 5 kilometers x 1000 = 5000 meters. Choice A (50 meters) is incorrect because it underestimates the conversion. Choice B (500 meters) is incorrect as it also underestimates the conversion. Choice D (0.5 meters) is incorrect as it incorrectly represents the conversion as less than a kilometer.

4. 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.

5. Convert 0.1 liter to milliliters.

• A. 10 ml
• B. 100 ml
• C. 1000 ml
• D. 1 ml

Correct answer: B

Rationale: To convert 0.1 liters to milliliters, you need to multiply by 1000, not 10000. Therefore, 0.1 liter converts to 100 ml. Choice A (10 ml) is incorrect because it is the equivalent of 0.01 liter. Choice C (1000 ml) is incorrect as it represents 1 liter. Choice D (1 ml) is significantly less than the correct conversion.
