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.

0.2 mg

B.

0.20 mg

C.

20 mg

D.

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 C

Explanation

Step 1: The order is to administer Morphine 5mg IV once immediately. The available concentration is 2.5 mg/mL. To find out how many mL of morphine the nurse should prepare for administration, we need to divide the ordered dose by the available concentration.

Step 2: Calculation: 5 mg ÷ 2.5 mg/mL = 2 mL So, the nurse should prepare 2 mL of morphine for administration.

Correct Answer is C

Explanation

Choice A reason:

Fetal head compression is associated with early decelerations, not late. Early decelerations are a normal finding during labor as the fetal head is compressed during contractions, leading to a vagal response that temporarily decreases the heart rate.

Choice B reason:

Umbilical cord compression leads to variable decelerations, not late. Variable decelerations can occur at any time during the contraction cycle and are caused by compression of the umbilical cord, which can restrict blood flow to the fetus.

The correct answer is C. Uteroplacental insufficiency.

Late decelerations are indicative of uteroplacental insufficiency, which is a condition where the placenta is not delivering enough oxygen and nutrients to the fetus.

Choice D reason:

Maternal bradycardia, which is a slower than normal heart rate in the mother, does not cause late decelerations in the fetus. Instead, maternal bradycardia can be a separate concern and does not directly affect the fetal heart rate pattern observed on the monitor.
