A medication order is 0.75 mg. How many micrograms is this?

• A. 500 mcg
• B. 1000 mcg
• C. 250 mcg
• D. 750 mcg

Answer: (D)

Converting between milligrams and micrograms hinges on the fact that 1 mg equals 1000 mcg. To find micrograms from milligrams, multiply by 1000. For 0.75 mg, 0.75 × 1000 equals 750, so the dose is 750 micrograms. This also fits the idea that 0.75 mg is three-quarters of a milligram, and three-quarters of 1000 mcg is 750 mcg. The other options correspond to 0.5 mg (500 mcg), 1 mg (1000 mcg), and 0.25 mg (250 mcg), which do not equal 0.75 mg.
