A client is prescribed 500 mcg of a medication but the Pharmacy delivers the medication in milligrams. How many milligrams of the medication should the nurse provide to the client?
1. 50
2. 5
3. 0.5
4. 0.05
3
Rationale 1: mg = 1 mg/ 1,000 mcg x 500 mcg/1. Multiply the numerators (1 x 500 = 500). Multiply the denominators (1,000 x 1 = 1,000). 500/1000 = 0.5.
