1. Convert 250 milliliters to liters.

• A. 25 liters
• B. 0.25 liters
• C. 2.5 liters
• D. 0.025 liters

Correct answer: B

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in a liter. Therefore, 250 milliliters is equal to 250/1000 = 0.25 liters. Choice A, 25 liters, is incorrect as it is a magnitude higher than the correct answer. Choice C, 2.5 liters, is also incorrect as it is 10 times greater than the correct conversion. Choice D, 0.025 liters, is incorrect as it is a magnitude lower than the correct conversion.

2. Convert 35.40 kilograms to grams (g).

• A. 354 g
• B. 35,400 g
• C. 3,540 g
• D. 3.54 g

Correct answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1,000 since there are 1,000 grams in a kilogram. Therefore, 35.40 kg × 1,000 = 35,400 grams. Choice A (354 g) is incorrect because it is off by a factor of 10. Choice C (3,540 g) is incorrect as it is off by a factor of 100. Choice D (3.54 g) is incorrect as it represents kilograms instead of grams.

3. Is 0.25 mg equal to 250 mcg?

• A. TRUE
• B. FALSE
• C. Sometimes
• D. None of the above

Correct answer: A

Rationale: The correct answer is A: TRUE. 0.25 mg is indeed equal to 250 mcg. This conversion is obtained by multiplying 0.25 mg by 1000 to convert it to micrograms. In pharmaceuticals, it is crucial to understand and convert between different dosage units accurately. Choice B is incorrect as the two quantities are equivalent. Choice C, 'Sometimes,' is misleading as the conversion from milligrams to micrograms follows a consistent ratio. Choice D, 'None of the above,' is incorrect as there is a definitive equivalence between the provided quantities.

4. What is 0.3 ml in tsp?

• A. 0.06 tsp
• B. 0.1 tsp
• C. 0.2 tsp
• D. 0.3 tsp

Correct answer: A

Rationale: To convert milliliters to teaspoons, you can use the conversion factor that there are approximately 5 milliliters in a teaspoon. When you divide 0.3 ml by 5, you get 0.06 teaspoons, which is equivalent to 0.06 tsp. Therefore, the correct answer is A. Choice B, 0.1 tsp, is incorrect because it does not result from the conversion of 0.3 ml to tsp. Choice C, 0.2 tsp, is also incorrect as it does not accurately represent the conversion. Choice D, 0.3 tsp, is the same value as the original quantity in milliliters, which is not the correct conversion to teaspoons.

5. How many milliliters are there in 0.5 liters?

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

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in a liter. Therefore, 0.5 liters is equal to 500 milliliters. Choices B, C, and D are incorrect because they do not reflect the correct conversion from liters to milliliters.
