4. 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.

Rationale: To convert milligrams to micrograms, you need to multiply by 1000 because there are 1000 micrograms in 1 milligram. Therefore, 0.175 mg x 1000 = 1750 mcg. The correct answer is 1750 mcg. Choices A, B, and D are incorrect because they do not account for the conversion factor of 1000 between milligrams and micrograms. It's crucial to understand these conversions in medical calculations to ensure accurate dosing and prevent medication errors.
