1. 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.

2. How many grams are in 0.5 kilograms?

• A. 50 grams
• B. 500 grams
• C. 5,000 grams
• D. 0.5 grams

Correct answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in 1 kilogram. Therefore, 0.5 kilograms is equal to 500 grams (0.5 x 1000 = 500). Choice A (50 grams) is incorrect as it is the result of multiplying by 10 instead of 1000. Choice C (5,000 grams) is incorrect as it is the result of adding an extra zero. Choice D (0.5 grams) is incorrect as it represents the original amount in grams, not the converted amount.

3. How many ounces is equal to 1 gram?

• A. 0.015 ounces
• B. 0.035 ounces
• C. 0.045 ounces
• D. 0.055 ounces

Correct answer: B

Rationale: To convert grams to ounces, you need to multiply the weight in grams by 0.035 to get the equivalent weight in ounces. Therefore, 1 gram is equal to 0.035 ounces. Choices A, C, and D are incorrect conversions and do not accurately represent the conversion factor from grams to ounces.

4. What is 0.004 as a simplified ratio?

• A. 1:250
• B. 4:35
• C. 7:28
• D. 4:00

Correct answer: A

Rationale: To convert 0.004 to a ratio, we first express it as 4/1000, which simplifies to 1/250. Hence, 0.004 is equivalent to the simplified ratio of 1:250. Choice B, 4:35, is incorrect as it does not reflect the correct conversion. Choice C, 7:28, is incorrect because it does not represent the simplified ratio of 0.004. Choice D, 4:00, is incorrect as it does not simplify to the original decimal value.

5. What is 0.4 expressed in inches?

• A. 0.04 inches
• B. 4 inches
• C. 0.4 inches
• D. 40 inches

Correct answer: C

Rationale: To express 0.4 in inches, you don't need to convert it further as it is already in inches. Therefore, the correct answer is 0.4 inches. Choice A (0.04 inches) is incorrect as it represents a smaller quantity. Choice B (4 inches) and Choice D (40 inches) are incorrect as they represent larger quantities, which are not equivalent to 0.4 inches.
