1. What is 0.25 mg to mcg?

• A. 250 mcg
• B. 25 mcg
• C. 2.5 mcg
• D. 2500 mcg

Correct answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you multiply by 1000 because 1 mg is equal to 1000 mcg. Therefore, 0.25 mg is equal to 250 mcg. Choices B, C, and D are incorrect as they do not consider the correct conversion factor.

2. Convert 354,000 millimeters to meters (m).

• A. 354 m
• B. 354 m
• C. 354,000 km
• D. 35,400 m

Correct answer: B

Rationale: To convert millimeters to meters, you need to divide by 1,000 since there are 1,000 millimeters in a meter. Therefore, 354,000 mm ÷ 1,000 = 354 meters. Choice A, '354 m,' is correct as it represents the converted value. Choice C, '354,000 km,' is incorrect as it suggests converting to kilometers instead of meters. Choice D, '35,400 m,' is incorrect as it is not the result of the correct conversion calculation.

3. What is 0.05 mg in mcg?

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

Correct answer: A

Rationale: 0.05 mg is equivalent to 50 mcg because 1 mg is equal to 1000 mcg. To convert milligrams to micrograms, you need to multiply by 1000. Therefore, 0.05 mg x 1000 = 50 mcg. Choices B, C, and D are incorrect because they do not correctly convert milligrams to micrograms. Option B (500 mcg) would be the result if the conversion was done incorrectly by adding an extra zero, while options C (5 mcg) and D (0.5 mcg) are incorrect due to miscalculating the conversion factor.

4. 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.

5. How many micrograms are in 0.15 mg?

• A. 150 mcg
• B. 15 mcg
• C. 1.5 mcg
• D. 1500 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, 0.15 mg is equal to 150 mcg. Choice B (15 mcg) is incorrect as it represents the conversion of 0.015 mg to mcg. Choice C (1.5 mcg) is incorrect as it represents the conversion of 0.0015 mg to mcg. Choice D (1500 mcg) is incorrect as it represents the conversion of 1.5 mg to mcg. So, the correct answer is 150 mcg, a conversion often used in medical dosing.
