A nurse is assisting in 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 transcription examples should the nurse use?
2.0 mg
0.2 mg
.2 mg
0.20 mg
0.20 mg
The Correct Answer is B
A. 2.0 mg: This notation indicates two milligrams, which is not equivalent to two tenths of a milligram.
B. 0.2 mg: This is the proper way to write two tenths of a milligram.
C. .2 mg: While it may be understood, it is not the preferred notation because it lacks a leading zero, which can lead to misinterpretation.
D. 0.20 mg: This is technically correct but not necessary. It suggests more precision than needed for two tenths and can be misinterpreted as a larger dose.

Correct Answer is B
Explanation
A. “I will hold the inhaler with my non-dominant hand." The inhaler should be held with the dominant hand for better control and coordination.
B. "I will hold my breath at least 10 seconds after inhaling the medication." Holding the breath for 10 seconds helps the medication to be absorbed effectively in the lungs.
C. "I will wait 10 min between each inhalation." The standard recommendation is to wait about 1 minute between inhalations to allow the first dose to work before administering the second.
D. "I will tilt my head forward while inhaling the medication." The head should be tilted slightly back to allow for better aerosol delivery into the lungs.
Correct Answer is ["0.6"]
Explanation
- Amount prescribed: 3 mg
- Amount available: 5 mg/mL
- mL needed = Amount prescribed / Amount available = 3 mg / 5 mg/mL = 0.6 mL.
