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. Withhold the digoxin dose for elevated BP: Elevated BP is not a contraindication for digoxin administration; rather, the heart rate is the critical factor.
B. Withhold the digoxin dose for decreased heart rate. A heart rate below 60 beats per minute is a contraindication for administering digoxin, as it can increase the risk of toxicity and bradycardia.
C. Administer digoxin 0.25 mg. Given the heart rate of 54/min, the nurse should not administer the full dose.
D. Administer digoxin 0.125 mg. While 0.125 mg may be appropriate in some cases, the heart rate should first be assessed to determine if the medication should be administered at all.
Correct Answer is C
Explanation
A. Notify the provider immediately if urine turns red-brown in color. Phenytoin can cause urine discoloration, but this is not typically a cause for immediate concern.
B. Obtain an annual flu vaccine while taking phenytoin. While vaccinations are important, there is no specific requirement for flu vaccination solely based on phenytoin use.
C. Shake the suspension vigorously prior to pouring the medication. Phenytoin suspension should be shaken gently to ensure even distribution of the medication.
D. Take an antacid with the medication to avoid gastric upset. Antacids should not be taken simultaneously with phenytoin, as they can decrease its absorption.
