Question:
A provider writes an order for viii mg of a medication. The
nurse must enter the dose into the electronic record using
Arabic numerals before administration. How many milligrams is
the ordered dose?
,Options:
A. 6 mg
B. 8 mg
C. 10 mg
D. 12 mg
Correct Answer: B. 8 mg
Rationale:
Correct: viii equals 8. The nurse should transcribe the order as 8
mg before verifying the medication against the MAR. Accurate
numeral conversion prevents transcription errors.
A: 6 mg would reflect an incorrect Roman numeral conversion.
C: 10 mg would be x, not viii.
D: 12 mg would be xii, not viii.
Teaching Point: Roman numerals must be converted correctly
before dose verification.

Question:
A medication label in a legacy order reads xiv mg. The nurse is
,preparing to transcribe the order into Arabic numerals. What
dose should the nurse document?
Options:
A. 12 mg
B. 14 mg
C. 16 mg

C: 16 mg is not represented by xiv.
D: 18 mg is not represented by xiv.
Teaching Point: Roman numerals must be read exactly as
written to avoid dosing errors.

, Question:
The provider orders 3/4 tablet of a medication. Each scored
tablet contains 500 mg. How many milligrams will the nurse
administer?
Options:
A. 250 mg
B. 375 mg
C. 400 mg
D. 500 mg
Correct Answer: B. 375 mg
Rationale:
Correct: Set up dimensional analysis: 3/4 tablet × 500 mg / 1
tablet = 375 mg. The tablets cancel, leaving milligrams.
A: 250 mg reflects half a tablet, not 3/4.
C: 400 mg is a common estimation error.
D: 500 mg would be the full tablet dose.
Teaching Point: Multiply the fraction of the tablet by the
strength on the label.
