The nurse has a medication bottle with the following drug label. How many g will the patient take per tablet?

The home-care nurse is visiting a patient. The patient has two medication bottles with the same drug name, Drug A. The first medication bottle has printed on its label, "Drug A 500 mcg in each tablet." The second medication bottle has printed on its label, "Drug A 0.5 mg in each tablet." Is the nurse correct in informing the patient that the doses are equivalent? Provide a rationale for your answer.
