A nurse is preparing an in-service program about preventing medication errors when transcribing a prescription. The nurse is using a dosage example of two tenths of a milligram. Which of the following examples should the nurse use to show appropriate transcription of this dosage?

A. 2 mg: This represents two milligrams, which is 10 times larger than the intended dose of 0.2 mg and could result in a serious medication error. B. 0.20 mg: Using a trailing zero can lead to misinterpretation if the decimal point is not clearly seen, potentially causing a tenfold overdose. C. 0.2 mg: Correct transcription for two tenths of a milligram. The leading zero before the decimal point prevents misreading as 2 mg, and no trailing zero is used. D. 2.0 mg: This would be read as two milligrams, which is ten times the intended dose and unsafe.
