The prescription is for 0.08 mg of a drug. How many micrograms should the nurse prepare?
Correct answer: C. 80 micrograms
- A. 0.8 micrograms
- B. 8 micrograms
- C. 80 micrograms
- D. 800 micrograms
Explanation
One milligram equals 1,000 micrograms, so 0.08 mg × 1,000 = 80 micrograms. The decimal must be moved three places to the right when converting milligrams to micrograms. Eight hundred micrograms would be ten times the prescribed dose.
