1) Arabic Numbers and Roman Numerals
Reference: Ch. 1 — Arabic Numbers and Roman Numerals
Question:
A medication label uses Roman numerals for the strength of a
tablet and reads X mg. The nurse must verify the dose before
administration. How many milligrams does the label indicate?
,A. 5 mg
B. 10 mg
C. 12 mg
D. 15 mg
Correct Answer: B. 10 mg
Rationale:
Correct Answer: X equals 10 in Roman numerals, so the
tablet strength is 10 mg. The nurse should translate Roman
numerals to Arabic numbers before giving the medication to
prevent dose errors.
A: V equals 5, not X. This would underdose the patient.
C: XII equals 12, not 10. This is a common numeral
substitution error.
D: XV equals 15, not 10. This would lead to a higher-than-
ordered dose.
Teaching Point: Roman numerals must be converted accurately
before medication administration.

2) Arabic Numbers and Roman Numerals
Reference: Ch. 1 — Arabic Numbers and Roman Numerals
Question:
The provider writes an order that includes XII mg of a
,medication. The nurse is checking the order against the label
before administration. How many milligrams is the dose?
A. 10 mg
B. 12 mg
C. 14 mg
D. 20 mg
Correct Answer: B. 12 mg
Rationale:
Correct Answer: XII equals 12. The nurse should identify the
Arabic equivalent before preparing the medication.
A: X equals 10, which is less than the ordered amount.
C: XIV equals 14, not XII. This reflects a numeral mix-up.
D: XX equals 20, which is not the ordered dose.
Teaching Point: Roman numeral recognition prevents
transcription errors.

3) Multiplying Fractions
Reference: Ch. 1 — Fractions — Multiplying Fractions
Question:
A child is prescribed 1/2 tablet twice daily for 4 days. The
, tablets are scored and may be split safely. How many tablets
will the nurse prepare in total?
A. 2 tablets
B. 4 tablets
C. 6 tablets
D. 8 tablets
Correct Answer: B. 4 tablets
Rationale:
Correct Answer: 12×2×4=4\frac{1}{2} \times 2 \times 4 =
421×2×4=4 tablets. The nurse multiplies the fraction dose by
the number of doses per day and number of days.
A: This reflects counting only one part of the schedule. It
ignores the full 4-day duration.
C: This likely comes from adding instead of multiplying.
D: This doubles the correct amount and is unsafe.
Teaching Point: Multiply the fraction dose by the number of
doses and days.
