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?

0.2 mg

0.20 mg

20 mg

2 mg

Answer and Explanation

The Correct Answer is A

Choice A rationale
The correct transcription of two tenths of a milligram is 0.2 mg. This format avoids any potential confusion that could lead to a medication error.
Choice B rationale
While 0.20 mg is technically correct, it is not the preferred format. The trailing zero after the decimal point is unnecessary and could potentially lead to confusion.
Choice C rationale
20 mg is not correct. This is 100 times the intended dose of two tenths of a milligram, and could lead to a serious medication error.
Choice D rationale
2 mg is not correct. This is 10 times the intended dose of two tenths of a milligram, and could lead to a medication error.

Correct Answer is A

Explanation

Choice A rationale
Methylergonovine is a medication that is primarily used to prevent or treat excessive bleeding after childbirth. It works by increasing the rate and strength of contractions and the stiffness of the uterus muscles, which helps to decrease bleeding. This medication is given in a hospital or clinic setting. Therefore, the nurse should inform the client that this medication is intended to prevent postpartum hemorrhage.
Choice B rationale
While preventing postpartum infection is important, methylergonovine is not specifically used for this purpose. Postpartum infection is typically prevented and treated with antibiotics and good hygiene practices.
Choice C rationale
Thromboembolic events, such as blood clots, can be a risk after childbirth. However, methylergonovine is not used to prevent these events. Anticoagulant medications are typically used to prevent thromboembolic events.
Choice D rationale
Methylergonovine is not used to prevent hypertension. In fact, it can cause increased blood pressure as a side effect. Therefore, it would not be used as a preventative measure for hypertension.

A. 0.5 mL B. 1 mL C. 1.5 mL D. 2 mL .

Correct Answer is A

Explanation

Step 1 is to calculate the volume of Toradol to be drawn up. Toradol is available in 60 mg/mL. Therefore, to administer a dose of 30 mg, the nurse would need to draw up 30 mg ÷ 60 mg/mL = 0.5 mL.
