1. Convert 0.1 liter to milliliters. What is the equivalent volume?

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

Correct answer: C

Rationale: To convert liters to milliliters, you need to multiply the number of liters by 1,000 because there are 1,000 milliliters in a liter. Therefore, 0.1 liter is equal to 100 milliliters. Choice A (1 ml) is incorrect because it represents the conversion of 0.01 liters, not 0.1 liters. Choice B (10 ml) is incorrect as it also represents the conversion of 0.01 liters. Choice D (1000 ml) is incorrect as it represents the conversion of 1 liter, not 0.1 liter.

2. How many millimeters (mm) are in 3.45 meters?

• A. 345 mm
• B. 3,450 mm
• C. 345,000 mm
• D. 3.45 mm

Correct answer: B

Rationale: To convert meters to millimeters, you need to multiply by 1,000 because there are 1,000 millimeters in a meter. Therefore, 3.45 meters × 1,000 = 3,450 millimeters. Choices A, C, and D are incorrect because they do not reflect the correct conversion factor from meters to millimeters.

3. What is the correct conversion of 35,400 milligrams to grams (g)?

• A. 35.4 g
• B. 35.4 g
• C. 354 g
• D. 354,000 g

Correct answer: B

Rationale: To convert milligrams to grams, you need to divide by 1,000 because there are 1,000 milligrams in a gram. Therefore, 35,400 mg ÷ 1,000 = 35.4 grams. Choice A is incorrect because it does not account for the conversion from milligrams to grams. Choice C is incorrect as it incorrectly drops a zero, leading to an inaccurate conversion. Choice D is incorrect as it incorrectly multiplies instead of dividing, resulting in a significantly larger value than the correct answer.

4. What is 0.5 liters in ml?

• A. 500 ml
• B. 50 ml
• C. 5 ml
• D. 0.5 ml

Correct answer: A

Rationale: The correct answer is A: 500 ml. To convert liters to milliliters, you multiply the number of liters by 1000 because 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters x 1000 = 500 milliliters. Choices B, C, and D are incorrect because they do not correctly convert 0.5 liters to milliliters based on the conversion factor of 1000 ml per liter.

5. How many micrograms (mcg) are equivalent to 0.5 milligrams (mg)?

• A. 500 mcg
• B. 50 mcg
• C. 5 mcg
• D. 0.5 mcg

Correct answer: A

Rationale: To convert milligrams to micrograms, you need to multiply by 1000 because there are 1000 micrograms in 1 milligram. Therefore, 0.5 mg x 1000 = 500 mcg. This conversion is crucial in medication dosage calculations to ensure precise administration. Choice B, 50 mcg, is incorrect as it represents 0.05 mg. Choice C, 5 mcg, is incorrect as it corresponds to 0.005 mg. Choice D, 0.5 mcg, is incorrect because it is the same value as the initial amount in milligrams, rather than the converted value to micrograms.
